  • Why do I have an error when adding states in slick?

    - by SystemNetworks
    When I was going to create another state I had an error. This is my code: public static final int play2 = 3; and public Game(String gamename){ this.addState(new mission(play2)); } and public void initStatesList(GameContainer gc) throws SlickException{ this.getState(play2).init(gc, this); } I have an error in the addState. above the above code. I don't know where is the problem. But if you want the whole code it is here: package javagame; import org.newdawn.slick.*; import org.newdawn.slick.state.*; public class Game extends StateBasedGame{ public static final String gamename = "NET FRONT"; public static final int menu = 0; public static final int play = 1; public static final int train = 2; public static final int play2 = 3; public Game(String gamename){ super(gamename); this.addState(new Menu(menu)); this.addState(new Play(play)); this.addState(new train(train)); this.addState(new mission(play2)); } public void initStatesList(GameContainer gc) throws SlickException{ this.getState(menu).init(gc, this); this.getState(play).init(gc, this); this.getState(train).init(gc, this); this.enterState(menu); this.getState(play2).init(gc, this); } public static void main(String[] args) { try{ AppGameContainer app =new AppGameContainer(new Game(gamename)); app.setDisplayMode(1500, 1000, false); app.start(); }catch(SlickException e){ e.printStackTrace(); } } } //SYSTEM NETWORKS(C) 2012 NET FRONT

  • How to get this wavefront .obj data onto the frustum?

    - by NoobScratcher
    I've finally figured out how to get the data from a .obj file and store the vertex positions x,y,z into a structure called Points with members x y z which are of type float. I want to know how to get this data onto the screen. Here is my attempt at doing so: //make a fileobject and store list and the index of that list in a c string ifstream file (list[index].c_str() ); std::vector<int>faces; std::vector<Point>points; points.push_back(Point()); Point p; int face[4]; while ( !file.eof() ) { char modelbuffer[10000]; //Get lines and store it in line string file.getline(modelbuffer, 10000); switch(modelbuffer[0]) { case 'v' : sscanf(modelbuffer, "v %f %f %f", &p.x, &p.y, &p.z); points.push_back(p); cout << "Getting Vertex Positions" << endl; cout << "v" << p.x << endl; cout << "v" << p.y << endl; cout << "v" << p.z << endl; break; case 'f': sscanf(modelbuffer, "f %d %d %d %d", face, face+1, face+2, face+3 ); cout << face[0] << endl; cout << face[1] << endl; cout << face[2] << endl; cout << face[3] << endl; faces.push_back(face[0]); faces.push_back(face[1]); faces.push_back(face[2]); faces.push_back(face[3]); } GLuint vertexbuffer; glGenBuffers(1, &vertexbuffer); glBindBuffer(GL_ARRAY_BUFFER, vertexbuffer); glBufferData(GL_ARRAY_BUFFER, points.size(), points.data(), GL_STATIC_DRAW); //glBufferData(GL_ARRAY_BUFFER,sizeof(points), &(points[0]), GL_STATIC_DRAW); glVertexAttribPointer(0, 4, GL_FLOAT, GL_FALSE, 0, 0); glVertexPointer(3, GL_FLOAT, sizeof(points),points.data()); glIndexPointer(GL_DOUBLE, 0, faces.data()); glDrawArrays(GL_QUADS, 0, points.size()); glDrawElements(GL_QUADS, faces.size(), GL_UNSIGNED_INT, faces.data()); } As you can see I've clearly failed the end part but I really don't know why its not rendering the data onto the frustum? Does anyone have a solution for this?

  • XNA Drag Gestures - fractional delta values

    - by Den
    I have an issue with objects moving roughly twice as far as expected when dragging them. I am comparing my application to the standard TouchGestureSample sample from MSDN. For some reason in my application gesture samples have fractional positions and deltas. Both are using same Microsoft.Xna.Framework.Input.Touch.dll, v4.0.30319. I am running both apps using standard Windows Phone Emulator. I am setting my break point immediately after this line of code in a simple Update method: GestureSample gesture = TouchPanel.ReadGesture(); Typical values in my app: Delta = {X:-13.56522 Y:4.166667} Position = {X:184.6956 Y:417.7083} Typical values in sample app: Delta = {X:7 Y:16} Position = {X:497 Y:244} Have anyone seen this issue? Does anyone have any suggestions? Thank you.

  • Black or White Border/Shadow around PNGs in SDL/OPENGL

    - by Dylan
    having the same issue as this: Why do my sprites have a dark shadow/line/frame surrounding the texture? however, when I do the fix suggested there (changing GL_SRC_ALPHA to GL_ONE) it just replaces the black border with a white border on the images, and messes with my background color and some polygons I'm drawing (not all of them weirdly) by making them much lighter... any ideas? heres some of my relevant code. init: glMatrixMode(GL_PROJECTION); glLoadIdentity(); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glEnable(GL_DEPTH_TEST); glEnable(GL_MULTISAMPLE); glEnable(GL_TEXTURE_2D); glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE); glAlphaFunc(GL_GREATER, 0.01); glEnable(GL_ALPHA_TEST); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glEnable(GL_BLEND); when each texture is loaded: glGenTextures(1, &textureID); glBindTexture(GL_TEXTURE_2D, textureID); gluBuild2DMipmaps(GL_TEXTURE_2D, GL_RGBA, surface->w, surface->h, GL_BGRA, GL_UNSIGNED_BYTE, surface->pixels); glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_LINEAR); glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);

  • Amazon GameCircle Integration

    - by user1095509
    I'm trying to integrate Amazon GameCircle and I have been able to successfully initialize GameCircle in my app, but the problem is when I click on the button that displays achievements, the GameCircle achievement list comes up but it says "You have unlocked 0 of 0 achievements". Same happens with leaderboards i.e there are no leaderboards for this app. I have created a Leaderboard and a few achievements on the online developer portal for Amazon but they don't show for some reason. Can someone help me with this. Any links/resources that help with integrating GameCircle will be appreciated. Thanks.

  • Character with several colliders and rigidbodies

    - by Lautaro
    I am doing a PvP fighting game. This is the GameObject hierarchy of the player character. Player contains: Legs Sword Torso Head I want to be able to Register impacts of the sword on a specific body part Use AddForce on the whole player entity when a body part is struck Change the animation of the player that owns the sword that hit Questions Is it correct that the only rigidbody should be on the root Player GameObject ? Is it correct that The body parts should have colliders and be triggers ? Is it correct that The swords should have colliders but not be trigger ?

  • Create Adventure Game Scene/Room/Backdrop from Real Photo

    - by Lyuben
    Is there a suitable software or a good tutorial for creating 2D rooms/scenery for adventure games from real photos? Is it possible to achieve good results by using photos, or the hand-drawn style will always be the best choice? Thank you! --- EDIT --- I want to clarify that I'm particularly interested in the art creation process, not on the environment in which to build games. I'm writing the game in Java for Android, but I don't think it matters. Also, I'm not trying to decide if the game will have photo realistic rooms or not - I want to achieve 2d pixelated, old-school style background scenes and I wonder if this can be made from photos, because I cannot draw them myself. For example, can I shoot a scene with my camera and then make it look something like the image in the following link: PIXEL ART FOREST I know that I cannot get the same quality as an absolutely hand-drawn pixel, but I'm looking for some decent technology/tutorial/software to make them somewhat similar.

  • I Need Help With A Game (Well The API)! [closed]

    - by user1758938
    I'm not "sure" which API (or language) I should use for a little 3D FPS game I'm gonna make although I don't have helpers lol. Anyway I'm ok with Java, C# and C++ but I need a good setup (easy to use) with the tools I need to make the game. I tried things like XNA but I want to check other options first because I don't like how it makes a installer and stuff, it's really annoying. I Need A API That Can Do These Things: 3D Rendering Input Sound And If It's Not Too Much To Ask Some Cool Shaders, Dynamic Lighting And A 3D Sound System Im "Ok" If I Have To Use Multiple APIs To Do This But Please Help Me!

  • How to acheive a smoother lighting effect

    - by Cyral
    I'm making a tile based game in XNA So currently my lightning looks like this: How can I get it to look like this? Instead of each block having its own tint, it has a smooth overlay. I'm assuming some sort of shader, and to tell it the lighting and blur it some how. But im not an expert with shaders. My current lighting calculates the light, and then passes it to a spritebatch and draws with a color parameter EDIT: No longer uses spritebatch tint, I was testing and now pass parameters to set the light values. But still looking for a way to smooth it

  • SpriteBatch.Begin() making my model not render correctly

    - by manning18
    I was trying to output some debug information using DrawString when I noticed my model suddenly was being rendered like it was inside-out (like the culling had been disabled or something) and the texture maps weren't applied I commented out the DrawString method until I only had SpriteBatch.Begin() and .End() and that was enough to cause the model rendering corruption - when I commented those calls out the model rendered correctly What could this be a symptom of? I've stripped it down to the barest of code to isolate the problem and this is what I noticed. Draw code below (as stripped down as possible) GraphicsDevice.Clear(Color.LightGray); foreach (ModelMesh mesh in TIEAdvanced.Meshes) { foreach (Effect effect in mesh.Effects) { if (effect is BasicEffect) ((BasicEffect)effect).EnableDefaultLighting(); effect.CurrentTechnique.Passes[0].Apply(); } } spriteBatch.Begin(); spriteBatch.DrawString(spriteFont, "Camera Position: " + cameraPosition.ToString(), new Vector2(10, 10), Color.Blue); spriteBatch.End(); GraphicsDevice.DepthStencilState = DepthStencilState.Default; TIEAdvanced.Draw(Matrix.CreateScale(0.025f), viewMatrix, projectionMatrix);

  • Unity: Assigning String value in inspector

    - by Marc Pilgaard
    I got an issue with Unity I can't seem to comprehend, and it is possibly very simple: I am trying to write a simple piece of code in JavaScript where a button toggles the activation of a shield, by dragging a prefab with Resources.load("ActivateShieldPreFab") and destroying it again (Haven't implemented that yet). I wish to assign this button through the inspector, so I have created a string variable which appears as intended in the inspector. Though it doesn't seem to register the inspector input, even though I changed the value through the inspector. It only provides the error: "Input Key named: is unknown" When the button name is assigned within the code, there is no issues. Code as follows: var ShieldOn = false; var stringbutton : String; function Start(){ } function Update () { if(Input.GetKey(stringbutton) && ShieldOn != true) { Instantiate(Resources.load("ActivateShieldPreFab"), Vector3 (0, 0, 0), Quaternion.identity); ShieldOn = true; } } Hope somebody can help, in advance... Thanks

  • How do history generation algorithms work?

    - by Bane
    I heard of the game Dwarf Fortress, but only now one of the people I follow on Youtube made a commentary on it... I was more than surprised when I noticed how Dwarf Fortress actually generates a history for the world! Now, how do these algorithms work? What do they usually take as input, except the length of the simulation? How specific can they be? And more importantly; can they be made in Javascript, or is Javascript too slow? (I guess this depends on the depth of the simulation, but take Dwarf Fortress as an example.)

  • Movement in RPG

    - by user1264811
    I want to make an RPG game in which I move tile by tile. So when I hit up, the tile row that I am on decreases by one for example. Also, it's supposed to be a slow movement so that I can see the change in tile, i.e. I can see my sprite move from tile to tile. Currently, with the code I have, when I hit a direction on my keyboard, I move several blocks within seconds and by the time I release the button I have already gotten a nullPointerException error because I have left the map. How can I slow down the movement?

  • How to had operation with character/items on binary with concrete operations on C++?

    - by Piperoman
    I have the next problem. A item can had a lot of states: NORMAL = 0000000 DRY = 0000001 HOT = 0000010 BURNING = 0000100 WET = 0001000 COLD = 0010000 FROZEN = 0100000 POISONED= 1000000 A item can had some states at same time but not all of them Is impossible to be dry and wet at same time. If you COLD a WET item, it turns into FROZEN. If you HOT a WET item, it turns into NORMAL A item can be BURNING and POISON Etc. I have try to set binary flags to states, and use AND to set operation to combine different states, checking before if is possible or not to do it, or change to another status. Exist a concrete patron to solve this problem efficiently without had a interminable switch that check every states with everynew states? It is relative easy to check 2 different states, but if exist a third state it is not trivial to do.

  • Bridge made out of blocks at an angle

    - by Pozzuh
    I'm having a bit of trouble with the math behind my project. I want the player to be able to select 2 points (vectors). With these 2 points a floor should be created. When these points are parallel to the x-axis it's easy, just calculate the amount of blocks needed by a simple division, loop through that amount (in x and y) and keep increasing the coordinate by the size of that block. The trouble starts when the 2 vectors aren't parallel to an axis, for example at an angle of 45 degrees. How do I handle the math behind this? If I wasn't completely clear, I made this awesome drawing in paint to demonstrate what I want to achieve. The 2 red dots would be the player selected locations. (The blocks indeed aren't square.) http://i.imgur.com/pzhFMEs.png.

  • How can I read a portion of one Minecraft world file and write it into another?

    - by RapierMother
    I'm looking to read block data from one Minecraft world and write the data into certain places in another. I have a Minecraft world, let's say "TemplateWorld", and a 2D list of Point objects. I'm developing an application that should use the x and y values of these Points as x and z reference coordinates from which to read constant-sized areas of blocks from the TemplateWorld. It should then write these blocks into another Minecraft world at constant y coordinates, with x & z coordinates determined based on each Point's index in the 2D list. The issue is that, while I've found a decent amount of information online regarding Minecraft world formats, I haven't found what I really need: more of a breakdown by hex address of where/what everything is. For example, I could have the TemplateWorld actually be a .schematic file rather than a world; I just need to be able to read the bytes of the file, know that the actual block data starts always at a certain address (or after a certain instance of FF, etc.), and how it's stored. Once I know that, it's easy as pie to just read the bytes and store them.

  • Is there any simple game that involves psychological factors?

    - by Roman
    I need to find a simple game in which several people need to interact with each other. The game should be simple for an analysis (it should be simple to describe what happens in the game, what players did). Because of the last reason, the video games are not appropriate for my purposes. I am thinking of a simple, schematic, strategic game where people can make a limited set of simple moves. Moreover, the moves of the game should be conditioned not only by a pure logic (like in chess or go). The behavior in the game should depend on psychological factors, on relations between people. In more details, I think it should be a cooperation game where people make their decisions based on mutual trust. It would be nice if players can express punishment and forgiveness in the game. Does anybody knows a game that is close to what I have described above? ADDED I need to add that I need a game where actions of players are simple and easy to formalize. Because of that I cannot use verbal games (where communication between players is important). By simple actions I understand, for example, moves on the board from one position to another one, or passing chips from one player to another one and so on.

  • Animations / OpenGL (ES 2) in game menu

    - by user16547
    (I am specifically asking for Android) If you look at Angry Birds (and in fact many other games), you can already see a lot of animations & effects going in the main menu and in other places even before starting to play. I assume they are done with OpenGL, more precisely a FrameLayout is used and inside it a GLSurfaceView is somewhere at the bottom of the hierarchy; above the GLSurfaceView you have regular Android buttons and texts. Is this how it's done*? Also would you reuse the same GLSurfaceView when running the actual game or should another one be created? *I am aware an alternative approach would be to make absolutely everything in OpenGL. Of these two I prefer the FrameLayout one, but I don't know whether other developers agree.

  • How to get the blocks seen by the player?

    - by m4tx
    I'm writing a Minecraft-like game using Ogre engine and I have a problem. I must optimize my game, because when I try draw 10000 blocks, I have 2 FPS... So, I got the idea that blocks display of the plane and to hide the invisible blocks. But I have a problem - how do I know which blocks at a time are visible to the player? And - if you know of other optimization methods for such a game, write what and how to use them in Ogre.

  • How many achievements should I include, and of what challenge?

    - by stephelton
    I know this question is fairy broad and subjective, but I'm wondering if there's been any published research into what an optimal number of achievements is and what kind of challenge they should present. The game this question directly relates to is a shoot-em-up, but an ideal answer is fairly theoretical. If there are there are too few achievements, or they are not challenging, I would expect they would fail in their goal to keep people playing. If there are too many, or they are unreasonably difficult, I would expect people to quickly give up. I personally witnessed the latter happening in Starcraft 2; a section of the achievements would have you win hundreds of games against their AI opponents (boring!)

  • Architectural approaches to creating a game menu/shell overlay on PC/Linux?

    - by Ghopper21
    I'm am working on a collection of games for a custom digital tabletop installation (similar to Microsoft Surface tables). Each game will be an individual executable that runs full-screen. In addition, there needs to be a menu/shell overlay program running simultaneously. The menu/shell will allow users to pause games, switch to other games, check their game history, etc. Some key requirements of the shell: it intercepts all user input (mainly multitouch) first before passing it on to the currently running game (so that it can, for instance, know to pop-up at a "pause" command); can reveal on arbitrary portions of the screen, with the currently running (but presumably paused) game still showing underneath, ideally with its shape/size being dynamic, to allow for creation of an animated in/out drawer effect over the game. I'm currently looking into different architectural approaches to this problem, including Fraps and DirectX overlays, but I'm sure I'm missing some ways to think about this. What are the main approaches I should be considering? (Note the table is currently being run by Windows PC, but it could potentially be a Linux box instead.)

  • On Screen Coin Animation

    - by Siddharth
    am working with side scrolling skater game. I want to perform coin animation such that as player collect coin it moves upside and attach with currency sprite. My main character and coin present in game scene and currency sprite present in HUD layer. This situation creates problem for me. Directly I can not apply modifier to coin because it is side scrolling game so based on main character speed it reaches at different position. That I have checked. So that I have to generate other coin at same position at game layer coin has, in HUD layer and move upward to it. But I didn't able to get its y position correct though I can able to get x position correctly. Many time main character goes downward so it get minus value many time. I also tried following code float[] position = GameHUD.this .convertSceneCoordinatesToLocalCoordinates(GameManager .getInstance().getCoinX(), GameManager.getInstance() .getCoinY()); But I am getting same coordinate as I provide. No difference in that so please some one provide me guidance in that. Because I am near to complete my game. EDIT: Here game layer and hud layer is totally different. Actual coin present in game layer which player has to collect and at same position I want to generate another coin in hud layer to perform some animation. It is recommended to generate coin in hud layer because through that only I can able to complete my target.

  • How do I get the point coords of a rotated SFML shaperect?

    - by user15498
    I am trying to get collisions of bullets working, and am using SFML. I am using code to get the position of the points of the rectangle for collisions, however I think there's a way to do this without having to get points but by simply getting the points from SFML, since the shape is a rectangle and the points are stored in that way. Is there a way to do that? Through a combination of getPoint() and getGlobalBounds() maybe? While on this topic, is it better to use shapeRects or sprites? I used to only use sprites, however with the addition of textures and more low level stuff I think it would be best to switch to using rectangles and setting their size.
