  • Sprites as Actors

    - by Scán
    Hello, I'm not experienced in GameDev questions, but as a programmer. In the language Scala, you can have scalable multi-tasking with Actors, very stable, as I hear. You can even habe hundreds of thousands of them running at once without a problem. So I thought, maybe you can use these as a base class for 2D-Sprites, to break out of the game-loop thing that requires to go through all the sprites and move them. They'd basically move themselves, event-driven. Would that make sense for a game? Having it multitasked like that? After all, it will run on the JVM, though that should not be much of a problem nowadays.

  • How to I get a rotated sprite to move left or right?

    - by rphello101
    Using Java/Slick 2D, I'm using the mouse to rotate a sprite on the screen and the directional keys (in this case, WASD) to move the spite. Forwards and backwards is easy, just position += cos(ang)*speed or position -= cos(ang)*speed. But how do I get the sprite to move left or right? I'm thinking it has something to do with adding 90 degrees to the angle or something. Any ideas? Rotation code: int mX = Mouse.getX(); int mY = HEIGHT - Mouse.getY(); int pX = sprite.x+sprite.image.getWidth()/2; int pY = sprite.y+sprite.image.getHeight()/2; double mAng; if(mX!=pX){ mAng = Math.toDegrees(Math.atan2(mY - pY, mX - pX)); if(mAng==0 && mX<=pX) mAng=180; } else{ if(mY>pY) mAng=90; else mAng=270; } sprite.angle = mAng; sprite.image.setRotation((float) mAng); And the movement code (delta is change in time): Input input = gc.getInput(); Vector2f direction = new Vector2f(); Vector2f velocity = new Vector2f(); direction.x = (float) Math.cos(Math.toRadians(sprite.angle)); direction.y = (float) Math.sin(Math.toRadians(sprite.angle)); if(direction.length()>0) direction = direction.normalise(); //On a separate note, what does this line of code do? velocity.x = (float) (direction.x * sprite.moveSpeed); velocity.y = (float) (direction.y * sprite.moveSpeed); if(input.isKeyDown(sprite.up)){ sprite.x += velocity.x*delta; sprite.y += velocity.y*delta; }if (input.isKeyDown(sprite.down)){ sprite.x -= velocity.x*delta; sprite.y -= velocity.y*delta; }if (input.isKeyDown(sprite.left)){ //??? }if (input.isKeyDown(sprite.right)){ //??? }

  • Need help in determing what, if any, tools can be used to create a free Flash game

    - by ReaperOscuro
    Yes I proudly -and sadly- declare that I am a complete nincompoop when it comes to Flash, and I have been fishing around the big wide web for information. The reason for this is that I have been contracted to create a game(s) for a website -the usual flash-based games caveat. Please I do not mean things like by those gaming generator websites, I mean small yet professional games- but the caveat, as always, is that impossible dream: it needs to be done all for free. The budget...well imagine it as not there. Annoyingly is that I am a game designer yes, but with a ridiculously tight deadline I haven't got much time to re-learn (ah the heady days of programming at uni) everything by the end of March, so I'd like to ask some people who know their stuff rather than keep looking at a gazillion different things. This is my understanding: with the flash sdk you can create a game, albeit you need to be pretty programming savvy. FlashDevelop helps there -yet I am not entirely sure how. Yet even FD says to use Flash for the animation/graphics. Yes its undeniably powerful but as I said there is the unattainable demand of no money. The million dollar question: what, if any, tools can I use to create a free flash game?

  • How can I fade something to clear instead of white?

    - by Raven Dreamer
    I've got an XNA game which essentially has "floating combat text": short-lived messages that display for a fraction of a second and then disappear. I've recently added a gradual "fade-away" effect, like so: public void Update() { color.A -= 10; position.X += 3; if (color.A <= 10) isDead = true; } Where color is the Color int the message displays as. This works as expected, however, it fades the messages to white, which is very noticeable on my indigo background. Is there some way to fade it to transparent, rather than white? Lerp-ing towards the background color isn't an option, as there's a possibility there will be something between the text and the background, which would simply be the inverse of the current problem.

  • Obtaining a HBITMAP/HICON from D2D Bitmap

    - by Tom
    Is there any way to obtain a HBITMAP or HICON from a ID2D1Bitmap* using Direct2D? I am using the following function to load a bitmap: http://msdn.microsoft.com/en-us/library/windows/desktop/dd756686%28v=vs.85%29.aspx The reason I ask is because I am creating my level editor tool and would like to draw a PNG image on a standard button control. I know that you can do this using GDI+: HBITMAP hBitmap; Gdiplus::Bitmap b(L"a.png"); b.GetHBITMAP(NULL, &hBitmap); SendMessage(GetDlgItem(hDlg, IDC_BUTTON1), BM_SETIMAGE, IMAGE_BITMAP, (LPARAM)hBitmap); Is there any equivalent, simple solution using Direct2D? If possible, I would like to render multiple PNG files (some with transparency) on a single button.

  • Corona SDK: Quality of support and resources?

    - by Nick Wiggill
    I've not used Corona SDK before and am looking into it for a friend. (He is also considering Unity.) I wonder what the support is like for Corona? While Unity has a great many customers and so the Unity team can often not address issues directly, the community at large is very helpful and there are many excellent resources: tutorials, forum posts, code resources. What is Corona like in this regard, and by comparison?

  • Java - 2d Array Tile Map Collision

    - by Corey
    How would I go about making certain tiles in my array collide with my player? Like say I want every number 2 in the array to collide. I am reading my array from a txt file if that matters and I am using the slick2d library. Here is my code if needed. public class Tiles { Image[] tiles = new Image[3]; int[][] map = new int[500][500]; Image grass, dirt, mound; SpriteSheet tileSheet; int tileWidth = 32; int tileHeight = 32; public void init() throws IOException, SlickException { tileSheet = new SpriteSheet("assets/tiles.png", tileWidth, tileHeight); grass = tileSheet.getSprite(0, 0); dirt = tileSheet.getSprite(7, 7); mound = tileSheet.getSprite(2, 6); tiles[0] = grass; tiles[1] = dirt; tiles[2] = mound; int x=0, y=0; BufferedReader in = new BufferedReader(new FileReader("assets/map.txt")); String line; while ((line = in.readLine()) != null) { String[] values = line.split(","); for (String str : values) { int str_int = Integer.parseInt(str); map[x][y]=str_int; //System.out.print(map[x][y] + " "); y=y+1; } //System.out.println(""); x=x+1; y = 0; } in.close(); } public void update() { } public void render(GameContainer gc) { for(int x = 0; x < 50; x++) { for(int y = 0; y < 50; y ++) { int textureIndex = map[y][x]; Image texture = tiles[textureIndex]; texture.draw(x*tileWidth,y*tileHeight); } } } } I tried something like this, but I it doesn't ever "collide". X and y are my player position. if (tiles.map[(int)x/32][(int)y/32] == 2) { System.out.println("Collided"); }

  • XNA C# Platformer - physics engine or tile based?

    - by Hugh
    I would like to get some opinions on whether i should develop my game using a physics engine (farseer physics seems to be the best option) or follow the traditional tile-based method. Quick background: - its a college project, my first game, but have 4 years academic programming experience - Just want a basic platformer with a few levels, nothing fancy - want a shooting mechanic, run and gun, just like contra or metal slug for example - possibly some simple puzzles I have made a basic prototype with farseer, the level is hardcoded with collisions and not really tiled, more like big full-screen sized tiles, with collision bodies drawn manually along the ground and walls etc. My main problem is i want a simple retro feel to the jumping and physics but because its a physics simulation engine its going to be realistic, whereas typical in air controllable physics for platformers arent realistic. I have to make a box with wheel body fixture under it to have this effect and its glitchy and doesnt feel right. I chose to use a physics engine because i tried the tile method initially and found it very hard to understand, the engine took care of alot things to save me time, mainly being able to do slopes easily was nice and the freedom to draw collision bounds wherever i liked, rather then restricted to a grid, which gave me more freedom for art design also. In conclusion i don't know which method to pick, i want to use a method which will be the most straight forward way to implement and wont give me a headache later on, preferably a method which has an abundance of tutorials and resources so i dont get "stuck" doing something which has been done a million times before! Let me know i haven't provided enough information for you to help me! Thanks in advance, Hugh.

  • Dynamic character animation - Using the physics engine or not

    - by Lex Webb
    I'm planning on building a dynamic reactant animation engine for the characters in my 2D Game. I have already built templates for a skeleton based animation system using key frames and interpolation to specify a limbs position at any given moment in time. I am using Farseer physics (an extension of Box2D) in Monogame/XNA in C# My real question lies in how i go about tying this character animation into the physics engine. I have two options: Moving limbs using physics engine - applying a interpolated force to each limb (dynamic body) in order to attempt to get it to its position as donated by the skeleton animation. Moving limbs by simply changing the position of a fixed body - Updating the new position of each limb manually, attempting to take into account physics collisions. Then stepping the physics after the animation to allow for environment interaction. Each of these methods have their distinct advantages and disadvantages. Physics based movement Advantages: Possibly more natural/realistic movement Better interaction with game objects as force applying to objects colliding with characters would be calculated for me. No need to convert to dynamic bodies when reacting to projectiles/death/fighting. Disadvantages: Possible difficulty in calculating correct amount of force to move a limb a certain distance at a constant rate. Underlying character balance system would need to be created that would need to be robust enough to prevent characters falling over at the touch of a feather. Added code complexity and processing time for the above. Static Object movement Advantages: Easy to interpolate movement of limbs between game steps Moving limbs is as simple as applying a rotation to the skeleton bone. Greater control over limbs, wont need to worry about characters falling over as all animation would be pre-defined. Disadvantages: Possible unnatural movement (Depends entirely on my animation skills!) Bad physics collision reactions with physics engine (Dynamic bodies simply slide out of the way of static objects) Need to calculate collisions with physics objects and my limbs myself and apply directional forces to them. Hard to account for slopes/stairs/non standard planes when animating walking/running animations. Need to convert objects to dynamic when reacting to projectile/fighting/death physics objects. The Question! As you can see, i have thought about this extensively, i have also had Google into physics based animation and have found mostly dissertation papers! Which is filling me with sense that it may a lot more advanced than my mathematics skills. My question is mostly subjective based on my findings above/any experience you may have: Which of the above methods should i use when creating my game? I am willing to spend the time to get a physics solution working if you think it would be possible. In the end i want to provide the most satisfying experience for the gamer, as well as a robust and dynamic system i can use to animate pretty much anything i need.

  • Smarphone Apps. music, licenses and fees .. nightmare

    - by mm24
    I have recently asked a question about music in games like Guitar Hero. I have found that that in Europe (at least) if I do want to use a track composed by a musician member of a royalty collecting society I need to pay a flat fee to the society and not only to the member. So a "one-to-one" agreement is not valid and the society can come up to me and ask me for money for each download. Even if for FREE! This is a fee sheet list of the UK agency: for fee, see "Permanent download services" It is about 1,200 GBP for less than 22,000 copies and they DON'T specify anything more and they said me on the phone that I need to wait and see how many downloads I get before knowing the price. This is kind of crazy as If I give away the App for free I will have to PAY 1,200 GBP!! I am shocked and I feel very bad. One agency suggested me to use a fake name of the artist, but in this way is not fair to my collaborators as what they hope is that the App gets lots of downloads and in this way that other people will get to know about them and hopefully commission them more work. The other solution is to work only with non registered musicians. The question here to you is.. has anyone found a legal way to do use music from registered authors in a game?

  • How do walls affect lighting?

    - by Milkboat
    I have been trying to implement a simple form of lighting in my 2D game. In the screenshot, I don't think it looks very good, kind of just plastered over the top of the map. How would the wall effect how the lighting is displayed? Just looking for tips on how to make my lighting look a bit better. Right now I gave each tile a light value and I change that depending on if there is a light source near by. I don't take in account if there are any objects near by. Screenshot:

  • How to attach turrets to tiles in a tile based game

    - by Joseph St. Pierre
    I am a flash developer, and I am building a Tower Defense game. The world is being built through tiles, and I have gotten that accomplished easily. I have also gotten level changes and enemy spawning down as well. However, I wish the player to be able to spawn turrets, and have those turrets be on specific tiles, based upon where the player placed it. Here is my code: stop(); colOffset = 50; rowOffset = 50; guns = []; placed = true; dead = 0; spawned = 0; level = 1; interval = 350 / level; amount = level * 20; counter = 0; numCol = 14; numRow = 10; tiles = []; k = 0; create = false; tileName = new Array("road","grass","end", "start"); board = new Array( new Array(1,1,1,1,3,1,1,1,1,1,2,1,1,1), new Array(1,1,1,0,0,1,1,1,1,1,0,1,1,1), new Array(1,1,1,0,1,1,1,1,1,1,0,0,1,1), new Array(1,1,1,0,0,0,1,1,1,1,1,0,1,1), new Array(1,1,1,0,1,0,0,0,1,1,1,0,0,1), new Array(1,1,1,0,1,1,1,0,0,1,1,1,0,1), new Array(1,1,0,0,1,1,1,1,0,1,1,0,0,1), new Array(1,1,0,1,1,1,1,1,0,1,0,0,1,1), new Array(1,1,0,0,0,0,0,0,0,1,0,1,1,1), new Array(1,1,1,1,1,1,1,1,0,0,0,1,1,1) ); buildBoard(); function buildBoard(){ for ( col = 0; col < numCol; col++){ for ( row = 0; row < numRow; row++){ _root.attachMovie("tile", "tile_" + col + "_" + row, _root.getNextHighestDepth()); theTile = eval("tile_" + col + "_" + row); theTile._x = (col * 50); theTile._y = (row * 50); theTile.row = row; theTile.col = col; tileType = board[row][col]; theTile.gotoAndStop(tileName[tileType]); tiles.push(theTile); } } } init(); function init(){ onEnterFrame = function(){ counter += 1; if ( spawned < amount && counter > 50){ min= _root.attachMovie("minion","minion",_root.getNextHighestDepth()); min._x = tile_4_0._x + 25; min._y = tile_4_0._y + 25; min.health = 100; choose = Math.round(Math.random()); if ( choose == 0 ){ min.waypointX = [ tile_4_1._x +25, tile_3_1._x + 25, tile_3_2._x + 25, tile_3_6._x + 25, tile_2_6._x + 25, tile_2_8._x + 25, tile_8_8._x + 25, tile_8_9._x + 25, tile_10_9._x + 25, tile_10_7._x + 25, tile_11_7._x + 25, tile_11_6._x + 25, tile_12_6._x + 25, tile_12_4._x + 25, tile_11_4._x + 25, tile_11_2._x + 25, tile_10_2._x + 25, tile_10_0._x + 25]; min.waypointY = [ tile_4_1._y +25, tile_3_1._y + 25, tile_3_2._y + 25, tile_3_6._y + 25, tile_2_6._y + 25, tile_2_8._y + 25, tile_8_8._y + 25, tile_8_9._y + 25, tile_10_9._y + 25, tile_10_7._y + 25, tile_11_7._y + 25, tile_11_6._y + 25, tile_12_6._y + 25, tile_12_4._y + 25, tile_11_4._y + 25, tile_11_2._y + 25, tile_10_2._y + 25, tile_10_0._y + 25]; } else if ( choose == 1 ){ min.waypointX = [ tile_4_1._x +25, tile_3_1._x + 25, tile_3_2._x + 25, tile_3_3._x + 25, tile_5_3._x + 25, tile_5_4._x + 25, tile_7_4._x + 25, tile_7_5._x + 25, tile_8_5._x + 25, tile_8_8._x + 25, tile_8_9._x + 25, tile_10_9._x + 25, tile_10_7._x + 25, tile_11_7._x + 25, tile_11_6._x + 25, tile_12_6._x + 25, tile_12_4._x + 25, tile_11_4._x + 25, tile_11_2._x + 25, tile_10_2._x + 25, tile_10_0._x + 25 ]; min.waypointY = [ tile_4_1._y +25, tile_3_1._y + 25, tile_3_2._y + 25, tile_3_3._y + 25, tile_5_3._y + 25, tile_5_4._y + 25, tile_7_4._y + 25, tile_7_5._y + 25, tile_8_5._y + 25, tile_8_8._y + 25, tile_8_9._y + 25, tile_10_9._y + 25, tile_10_7._y + 25, tile_11_7._y + 25, tile_11_6._y + 25, tile_12_6._y + 25, tile_12_4._y + 25, tile_11_4._y + 25, tile_11_2._y + 25, tile_10_2._y + 25, tile_10_0._y + 25 ]; } min.i = 0; counter = 0; spawned += 1; min.onEnterFrame = function(){ dx = this.waypointX[this.i] - this._x; dy = this.waypointY[this.i] - this._y; radians = Math.atan2(dy,dx); degrees = radians * 180 / Math.PI; xspeed = Math.cos(radians); yspeed = Math.sin(radians); this._x += xspeed; this._y += yspeed; if( this._x == this.waypointX[this.i] && this._y == this.waypointY[this.i]){ this.i++; } if ( this._x == tile_10_0._x + 25 && this._y == tile_10_0._y + 25){ this.removeMovieClip(); dead += 1; } } } if ( dead >= amount ){ dead = 0; level += 1; amount = level * 20; spawned = 0; } } btnM.onRelease = function(){ create = true; } } game.onEnterFrame = function(){ } It is possible for me however to complete this task, but only once. I am able to make the turret, drag it over to a tile, and have it attach itself to the tile. No problem. The issue is, I cannot do these multiple times. Please Help.

  • Problems with texture orientation in space

    - by frankie
    I am currently drawing texture in 3D space and have some problems with it's orientation. I'd like me textures always to be oriented with front face to user. My desirable result looks like Note, that text size stay without changes when we rotating world and stay oriented with front face to user. Now I can draw text in 3D space, but it is not oriented with front but rotating with world. Such results I got with following shaders: Vertex Shader uniform vec3 Position; void main() { gl_Position = vec4(Position, 1.0); } Geometry Shader layout(points) in; layout(triangle_strip, max_vertices = 4) out; out vec2 fsTextureCoordinates; uniform mat4 projectionMatrix; uniform mat4 modelViewMatrix; uniform sampler2D og_texture0; uniform float og_highResolutionSnapScale; uniform vec2 u_originScale; void main() { vec2 halfSize = vec2(textureSize(og_texture0, 0)) * 0.5 * og_highResolutionSnapScale; vec4 center = gl_in[0].gl_Position; center.xy += (u_originScale * halfSize); vec4 v0 = vec4(center.xy - halfSize, center.z, 1.0); vec4 v1 = vec4(center.xy + vec2(halfSize.x, -halfSize.y), center.z, 1.0); vec4 v2 = vec4(center.xy + vec2(-halfSize.x, halfSize.y), center.z, 1.0); vec4 v3 = vec4(center.xy + halfSize, center.z, 1.0); gl_Position = projectionMatrix * modelViewMatrix * v0; fsTextureCoordinates = vec2(0.0, 0.0); EmitVertex(); gl_Position = projectionMatrix * modelViewMatrix * v1; fsTextureCoordinates = vec2(1.0, 0.0); EmitVertex(); gl_Position = projectionMatrix * modelViewMatrix * v2; fsTextureCoordinates = vec2(0.0, 1.0); EmitVertex(); gl_Position = projectionMatrix * modelViewMatrix * v3; fsTextureCoordinates = vec2(1.0, 1.0); EmitVertex(); } Fragment Shader in vec2 fsTextureCoordinates; out vec4 fragmentColor; uniform sampler2D og_texture0; uniform vec3 u_color; void main() { vec4 color = texture(og_texture0, fsTextureCoordinates); if (color.a == 0.0) { discard; } fragmentColor = vec4(color.rgb * u_color.rgb, color.a); } Any ideas how to get my desirable result?

  • Texture the quad with different parts of texture

    - by PolGraphic
    I have a 2D quad. Let say it's position is (5,10) and size is (7,11). I want to texture it with one texture, but using three different parts of it. I want to texture the part of quad from x = 5 to x = 7 with part of texture from U = 0 to U = 0.5 (replaying it after achieving 0.5, so I will have 4 same 0.5-lenght fragments). The second one with some other part of texture (also repeating it) and third in the same style. But, how to achieve it? I know that: float2 tc = fmod(input.TexCoord, textureCoordinates.zw - textureCoordinates.xy) + textureCoordinates.xy; //textureCoordinates.xy = fragments' offset Will give me the texture part replaying.

  • how to do event checks for loops?

    - by yao jiang
    I am having some trouble getting the logic down for this. Currently, I have an app that animates the astar pathfinding algorithm. On start of the app, the ui will show the following: User can press "space" to randomly choose start/end coords, then the app will animate it. Or, user can choose the start/end by left-click/right-click. During the animation, the user can also left-click to generate blocks, or right-click to choose a new destiantion. Where I am stuck at is how to handle the events while the app is animating. Right now, I am checking events in the main loop, then when the app is animating, I do event checks again. While it works fine, I feel that I am probably doing it wrong. What is the proper way of setting up the main loop that will handle the events while the app is animating? In main loop, the app start animating once user choose start/end. In my draw function, I am putting another event checker in there. def clear(rows): for r in range(rows): for c in range(rows): if r%3 == 1 and c%3 == 1: color = brown; grid[r][c] = 1; buildCoor.append(r); buildCoor.append(c); else: color = white; grid[r][c] = 0; pick_image(screen, color, width*c, height*r); pygame.display.flip(); os.system('cls'); # draw out the grid def draw(start, end, grid, route_coord): # draw the end coords color = red; pick_image(screen, color, width*end[1],height*end[0]); pygame.display.flip(); # then draw the rest of the route for i in range(len(route_coord)): # pausing because we want animation time.sleep(speed); # get the x/y coords x,y = route_coord[i]; event_on = False; if grid[x][y] == 2: color = green; elif grid[x][y] == 3: color = blue; for event in pygame.event.get(): if event.type == pygame.MOUSEBUTTONDOWN: if event.button == 3: print "destination change detected, rerouting"; # get mouse position, px coords pos = pygame.mouse.get_pos(); # get grid coord c = pos[0] // width; r = pos[1] // height; grid[r][c] = 4; end = [r, c]; elif event.button == 1: print "user generated event"; pos = pygame.mouse.get_pos(); # get grid coord c = pos[0] // width; r = pos[1] // height; # mark it as a block for now grid[r][c] = 1; event_on = True; if check_events([x,y]) or event_on: # there is an event # mark it as a block for now grid[y][x] = 1; pick_image(screen, event_x, width*y, height*x); pygame.display.flip(); # then find a new route new_start = route_coord[i-1]; marked_grid, route_coord = find_route(new_start, end, grid); draw(new_start, end, grid, route_coord); return; # just end draw here so it wont throw the "index out of range" error elif grid[x][y] == 4: color = red; pick_image(screen, color, width*y, height*x); pygame.display.flip(); # clear route coord list, otherwise itll just add more unwanted coords route_coord_list[:] = []; clear(rows); # main loop while not done: # check the events for event in pygame.event.get(): # mouse events if event.type == pygame.MOUSEBUTTONDOWN: # get mouse position, px coords pos = pygame.mouse.get_pos(); # get grid coord c = pos[0] // width; r = pos[1] // height; # find which button pressed, highlight grid accordingly if event.button == 1: # left click, start coords if grid[r][c] == 2: grid[r][c] = 0; color = white; elif grid[r][c] == 0 or grid[r][c] == 4: grid[r][c] = 2; start = [r,c]; color = green; else: grid[r][c] = 1; color = brown; elif event.button == 3: # right click, end coords if grid[r][c] == 4: grid[r][c] = 0; color = white; elif grid[r][c] == 0 or grid[r][c] == 2: grid[r][c] = 4; end = [r,c]; color = red; else: grid[r][c] = 1; color = brown; pick_image(screen, color, width*c, height*r); # keyboard events elif event.type == pygame.KEYDOWN: clear(rows); # one way to quit program if event.key == pygame.K_ESCAPE: print "program will now exit."; done = True; # space key for random start/end elif event.key == pygame.K_SPACE: # first clear the ui clear(rows); # now choose random start/end coords buildLoc = zip(buildCoor,buildCoor[1:])[::2]; #print buildLoc; (start_x, start_y, end_x, end_y) = pick_point(); while (start_x, start_y) in buildLoc or (end_x, end_y) in buildLoc: (start_x, start_y, end_x, end_y) = pick_point(); clear(rows); print "chosen random start/end coords: ", (start_x, start_y, end_x, end_y); if (start_x, start_y) in buildLoc or (end_x, end_y) in buildLoc: print "error"; # draw the route marked_grid, route_coord = find_route([start_x,start_y],[end_x,end_y], grid); draw([start_x, start_y], [end_x, end_y], marked_grid, route_coord); # return key for user defined start/end elif event.key == pygame.K_RETURN: # first clear the ui clear(rows); # get the user defined start/end print "user defined start/end are: ", (start[0], start[1], end[0], end[1]); grid[start[0]][start[1]] = 1; grid[end[0]][end[1]] = 2; # draw the route marked_grid, route_coord = find_route(start, end, grid); draw(start, end, marked_grid, route_coord); # c to clear the screen elif event.key == pygame.K_c: print "clearing screen."; clear(rows); # go fullscreen elif event.key == pygame.K_f: if not full_sc: pygame.display.set_mode([1366, 768], pygame.FULLSCREEN); full_sc = True; rows = 15; clear(rows); else: pygame.display.set_mode(size); full_sc = False; # +/- key to change speed of animation elif event.key == pygame.K_LEFTBRACKET: if speed >= 0.1: print SPEED_UP; speed = speed_up(speed); print speed; else: print FASTEST; print speed; elif event.key == pygame.K_RIGHTBRACKET: if speed < 1.0: print SPEED_DOWN; speed = slow_down(speed); print speed; else: print SLOWEST print speed; # second method to quit program elif event.type == pygame.QUIT: print "program will now exit."; done = True; # limit to 20 fps clock.tick(20); # update the screen pygame.display.flip();

  • Level Creating Help

    - by Brandon oubiub
    I am making a little 2d overhead RPG type game just for fun. I have almost all the basic stuff set up, but I just need a little help on level creation. I can already make a level and place each tile how I want it, but having to place each tile gets annoying after a while. I noticed that in a lot of games, even extremely simple ones, they have LOTS of levels with LOTS of tiles in each. Creating all that in this fashion would take forever. So I guess my question is, as a game developer, am I supposed to do all that, or maybe make a little level editor so I can see things as I create it? What do game developers do? I'm using Java. EDIT: Okay, say if I had an image for a map, that I made in MS paint or photoshop, and each pixel represent a tile value, could I somehow in Java detect what color an individual pixel is? If so, that would be perfect. If so, how?

  • How does an Engine like Source process entities?

    - by Júlio Souza
    [background information] On the Source engine (and it's antecessor, goldsrc, quake's) the game objects are divided on two types, world and entities. The world is the map geometry and the entities are players, particles, sounds, scores, etc (for the Source Engine). Every entity has a think function, which do all the logic for that entity. So, if everything that needs to be processed comes from a base class with the think function, the game engine could store everything on a list and, on every frame, loop through it and call that function. On a first look, this idea is reasonable, but it can take too much resources, if the game has a lot of entities.. [end of background information] So, how does a engine like Source take care (process, update, draw, etc) of the game objects?

  • When should a bullet texture be loaded in XNA?

    - by Bill
    I'm making a SpaceWar!-esque game using XNA. I want to limit my ships to 5 active bullets at any time. I have a Bullet DrawableGameComponent and a Ship DrawableGameComponent. My Ship has an array of 5 Bullet. What is the best way to manage the Bullet textures? Specifically, when should I be calling LoadTexture? Right now, my solution is to populate the Bullet array in the Ship's constructor, with LoadTexture being called in the Bullet constructor. The Bullet objects will be disabled/not visible except when they are active. Does the texture really need to be loaded once for each individual instance of the bullet object? This seems like a very processor-intensive operation. Note: This is a small-scale project, so I'm OK with not implementing a huge texture-management framework since there won't be more than half a dozen or so in the entire game. I'd still like to hear about scalable solutions for future applications, though.

  • XNA GUI: Creating a 'scroll pane' widget

    - by Keith Myers
    I'm trying to create a simple GUI system and am currently stuck on how to implement a textarea with a scrollbar. In other words, the text is too large to fit into the view area. I want to learn how to do this, so I'd rather not use an already rolled API. I believe this could be done if the text were part of a texture, but if the game had a lot of unique dialog, this seems expensive. I researched creating a texture on the fly and writing to it, but came up with nothing. Any suggested strategies would be appreciated. I believe it boils down to: text in a texture and how? Or something I have not thought of...

  • What version of Java should I target for applets?

    - by Christopher Horenstein
    I recently deployed an applet that seems to require Java 6 Update 24. I assume the reason for this requirement is the matching JDK version I used to create the applet (I am new to Java). The fact that my applet requires a Java download/update for users who already have some version of Java installed is a big concern for me; the applets I'm creating slip into a web comic, so it's very disruptive. Having used the most recent version of Java, it seems as though I am able to assume that most of the readers I get will have to update Java to continue reading/playing. Is there a best practice concerning which version of Java to use to make the process of using an applet easy for end-users? Any reading material on this would be very helpful. Should I be using an older version of Java if I don't require new features? I am using Slick for 2D games.

  • Can't click on a button with startDrag() active on stage

    - by Pedro
    I need to know how can I enable mouse click on a button when I have a MouseEvent listener for the stage. I have a MClip associated with the mouse cursor: Mouse.hide(); scope.startDrag(true); And an MouseEnvet on the stage: stage.addEventListener(MouseEvent.CLICK, FunctionXYZ); When I try to click on any button they don't assume the function that I create for those buttons... for example, button for fullscreen, exit, help, etc... Thank you very much. BR, Pedro

  • Inverting matrix then decomposing gives different quaternion than decomposing then inverting the quat

    - by Fraser
    I'm getting different signs when I convert a matrix to quaternion and invert that, versus when I invert a matrix and then get the quaternion from it: Quaternion a = Quaternion.Invert(getRotation(m)); Quaternion b = getRotation(Matrix.Invert(m)); I would expect a and b to be identical (or inverses of each other). However, it looks like q1 = (x, y, -z, -w) while q2 = (-x, -y, w, z). In other words, the Z and W components have been switched for some reason. Note: getRotation() decomposes the transform matrix and returns just the rotation part of it (I've tried normalizing the result; it does nothing). The matrix m is a complete transform matrix and contains a translation (and possibly a scale) as well as a rotation. I'm using D3DXMatrixDecompose to do the actual decomposition.

  • Rotate/Translate object in local space

    - by Mathias Hölzl
    I am just trying to create a movementcontroller class for game entities. These class should transform the entity affected by the mouse and keyboard input. I am able to calculate the changed rotation and the new globalPosition. Then I multiply: newGlobalMatrix = changedRotationMatrix * oldGlobalMatrix; newGlobalMatrix = MatrixSetPosition(newPosition); The problem is that the object rotates around the global axis and not around the local axis. I use XNAMath for the matrix calculation.
