• Technique to have screen independent grid based puzzle with sprite animation

  - by Yan Cheng CHEOK

  Hello all, let's say I have a fixed size grid puzzle game (8 x 10). I will be using sprites animation, when the "pieces" in the puzzle is moving from one grid to another grid. I was wondering, what is the technique to have this game being implemented as screen resolution independent. Here is what I plan to do. 1) The data structure coordinate will be represented using double, with 1.0 as max value. // Puzzle grid of 8 x 10 Environment { double width = 0.8; double height = 1.0; } // Location of Sprite at coordinate (1, 1) Sprite { double posX = 0.1; double posY = 0.1; double width = 0.1; double height = 0.1; } // scale = PYSICAL_SCREEN_SIZE drawBitmap ( sprite_image, sprite_image_rect, new Rect(sprite.posX * Scale, sprite.posY * Scale, (sprite.posX + sprite.width) * Scale, (sprite.posY + sprite.Height) * Scale), paint ); 2) A large size sprite image will be used (128x128). As sprite image shall look fine if we scale from large size down to small size, but not vice versa. Besides the above mentioned technique, is there any other consideration I had missed out?

• Skyrim Creation Kit with Xbox 360

  - by funseiki

  I posted this on stackoverflow but was advised to post here (here is a link to the stackoverflow question). I'm hoping for constructive feedback on its plausibility. Update on progress: It looks like there are ways to stuff files back onto the console (horizon, modio, xplorer360, etc) and they do require some form of signing. As of now, though, I've had no luck. I was hoping I could get away with just placing the ".esp" into the directory containing marketplace downloads for Skyrim, along with the signed ".bsa" file (basically a zipped up file containing any extra content the .esp will need to refer that doesn't exist in the basic game). This doesn't work, at least not in the ways I've tried, so next I'm going to try install the entire game to my flash drive (if possible) and attempt to traverse through the game's directory (this is probably unlikely). If anyone else has suggestions or luck or wants more detail on my failures comment/answer away. Here is the question: I'm thinking about buying the PC version of Skyrim to get the Creation Kit (I already own a copy for the Xbox). I have read the faq and scoured plenty of forums to see if there was some way to mod Skyrim for a console (Xbox 360, in particular), but they are generally coming up negative. I realize the CreationKit is on the PC, but I was wondering if there was a way to set up the '.esp' (hopefully I'm interpreting this correctly) files to be placed on the Xbox 360 file system in a similar manner to how game add-ons are downloaded from the Xbox Live Marketplace. I believe it is possible to transfer saves between the console and the PC (e.g. google: 'skyrim mod xbox360'), but these are referencing items that already exist in the game (e.g. a console command for maximum carry weight does not require reference to new animations or models). It would probably be easier if one could navigate through the xbox's file system to see where the games' files are placed, but with the current setup, the file system is abstracted away. Any help or insight on the matter would be much appreciated. I would love to work on a project that would make it possible to let console gamers experience and enjoy all the great mods available to the PC community.

• SFML - Moving a sprite on mouseclick

  - by Mike

  I want to be able to move a sprite from a current location to another based upon where the user clicks in the window. This is the code that I have: #include <SFML/Graphics.hpp> int main() { // Create the main window sf::RenderWindow App(sf::VideoMode(800, 600), "SFML window"); // Load a sprite to display sf::Texture Image; if (!Image.LoadFromFile("cb.bmp")) return EXIT_FAILURE; sf::Sprite Sprite(Image); // Define the spead of the sprite float spriteSpeed = 200.f; // Start the game loop while (App.IsOpened()) { if (sf::Keyboard::IsKeyPressed(sf::Keyboard::Escape)) App.Close(); if (sf::Mouse::IsButtonPressed(sf::Mouse::Right)) { Sprite.SetPosition(sf::Mouse::GetPosition(App).x, sf::Mouse::GetPosition(App).y); } // Clear screen App.Clear(); // Draw the sprite App.Draw(Sprite); // Update the window App.Display(); } return EXIT_SUCCESS; } But instead of just setting the position I want to use Sprite.Move() and gradually move the sprite from one position to another. The question is how? Later I plan on adding a node system into each map so I can use Dijkstra's algorithm, but I'll still need this for moving between nodes.

• Can't get sprite to rotate correctly?

  - by rphello101

  I'm attempting to play with graphics using Java/Slick 2d. I'm trying to get my sprite to rotate to wherever the mouse is on the screen and then move accordingly. I figured the best way to do this was to keep track of the angle the sprite is at since I have to multiply the cosine/sine of the angle by the move speed in order to get the sprite to go "forwards" even if it is, say, facing 45 degrees in quadrant 3. However, before I even worry about that, I'm having trouble even getting my sprite to rotate in the first place. Preliminary console tests showed that this code worked, but when applied to the sprite, it just kind twitches. Anyone know what's wrong? int mX = Mouse.getX(); int mY = HEIGHT - Mouse.getY(); int pX = sprite.x; int pY = sprite.y; int tempY, tempX; double mAng, pAng = sprite.angle; double angRotate=0; if(mX!=pX){ tempY=pY-mY; tempX=mX-pX; mAng = Math.toDegrees(Math.atan2(Math.abs((tempY)),Math.abs((tempX)))); if(mAng==0 && mX<=pX) mAng=180; } else{ if(mY>pY) mAng=270; else mAng=90; } //Calculations if(mX<pX&&mY<pY){ //If in Q2 mAng = 180-mAng; } if(mX<pX&&mY>pY){ //If in Q3 mAng = 180+mAng; } if(mX>pX&&mY>pY){ //If in Q4 mAng = 360-mAng; } angRotate = mAng-pAng; sprite.angle = mAng; sprite.image.setRotation((float)angRotate);

• ActionScript - clicking and determining the sprite's class

  - by TheDarkIn1978

  i'd like to add all or most of my mouse events to stage, but in order to do that i need to be able to tell what is the type of the sprite being clicked. i've added two sprites to the display list, one of which is from a class called Square, the other from a class called Circle. var mySquare:Sprite = new Square(); var myCircle:Sprite = new Circle(); addChild(mySquare); addChild(myCircle); now when i click on these sprites, i'd like to know from which class they are from, or which type of sprite it is. //mousePoint returns mouse coordinates of the stage var myArray:Array = stage.getObjectsUnderPoint(mousePoint()); if (myArray[myArray.length - 1] is Sprite) ... so far i know how to do is determine if it IS a sprite display object, but since i'll only be working with sprites i need something more specific. rather than checking "is Sprite", is there a way i can check "is Square" or "is Circle"? if (myArray[myArray.length - 1] is Square)

• Custom Music in Skyrim's Creation Kit?

  - by CptSupermrkt

  Can you bring in external music such as mp3s? If so, how? I didn't see anything about this in the wiki Bethesda released. Also how does this work with regards to the Steam Workshop? Don't imagine they would appreciate uploading copyrighted content. I don't particularly care about making a public mod, I just want to screw around privately and create dungeons/towns using music from some of my favorite games. Thanks.

• Sprite transparency not effected libGDX

  - by Aon GoltzCrank

  I am making a game using libGDX and Tween Universal Engine. My problem is as follows: I have 2 screens so fars, a splash screen with the logo, and a second one which is the main menu. In the splash screen I use a SpriteBatch and a Sprite with the Texture of the image I want (which goes through some scaling.) Now I use the Tween engine, along with a created SpriteAccessor to control the alpha of the sprite. I fade the picture in, then fade it out, then change it to the next screen. In the next screen I have a single sprite, and a single, 3 slot, sprite array. In this screen I also use the tween engine, I fade the single sprite into the screen (it's the background image) then I try to, using the same method, (Tween.to) to change the alpah of the sprite array (each sprite by itself.), I first set it to 0 using Tween.set, then using the method I change it. This didn't work, after some tests I tried setting the alpha of a single sprite from the array to 0, and that didn't work. It's like the program is ignoring the alpha value, I even printed out the alpha value, it saying 0, but the sprite is visible. How can I fix this, or why might it be caused?

• Jittery Movement, Uncontrollably Rotating + Front of Sprite?

  - by Vipar

  So I've been looking around to try and figure out how I make my sprite face my mouse. So far the sprite moves to where my mouse is by some vector math. Now I'd like it to rotate and face the mouse as it moves. From what I've found this calculation seems to be what keeps reappearing: Sprite Rotation = Atan2(Direction Vectors Y Position, Direction Vectors X Position) I express it like so: sp.Rotation = (float)Math.Atan2(directionV.Y, directionV.X); If I just go with the above, the sprite seems to jitter left and right ever so slightly but never rotate out of that position. Seeing as Atan2 returns the rotation in radians I found another piece of calculation to add to the above which turns it into degrees: sp.Rotation = (float)Math.Atan2(directionV.Y, directionV.X) * 180 / PI; Now the sprite rotates. Problem is that it spins uncontrollably the closer it comes to the mouse. One of the problems with the above calculation is that it assumes that +y goes up rather than down on the screen. As I recorded in these two videos, the first part is the slightly jittery movement (A lot more visible when not recording) and then with the added rotation: Jittery Movement So my questions are: How do I fix that weird Jittery movement when the sprite stands still? Some have suggested to make some kind of "snap" where I set the position of the sprite directly to the mouse position when it's really close. But no matter what I do the snapping is noticeable. How do I make the sprite stop spinning uncontrollably? Is it possible to simply define the front of the sprite and use that to make it "face" the right way?

• Making my XNA sprite jump properly

  - by Matthew Morgan

  I have been having great trouble getting my sprite to jump. So far I have a section of code which with a single tap of "W" will send the sprite in a constant velocity upwards. I need to be able to make my sprite come back down to the ground a certain time or height after begining the jump. There is also a constant pull of velocity 2 on the sprite to simulate some kind of gravity. // Walking = true when there is collision detected between the sprite and ground if (Walking == true) if (keystate.IsKeyDown(Keys.W)) { Jumping = true; } if (Jumping == true) { spritePosition.Y -= 10; } Any ideas and help would be appreciated but I'd prefer a modified version of my code posted if at all possible.

• Simple thruster like behaviour when rotating sprite

  - by ensamgud

  I'm prototyping some 2D game concepts with XNA and have added some basic keyboard inputs to control a triangle sprite. When I press key up the sprite accelerates in it's current facing direction, when I release the key it brakes down. For rotation, when I press left/right keys I rotate the sprite. Currently the sprite immedately changes direction when I rotate it. What I want is for it to keep moving in the same direction when I rotate, until I hit key up, adding thrust in whatever direction the sprite is pointing at. This would simulate thrusters on a classic space shooter like Asteroids. I'm adding an image to describe the behaviour I'm after and some code samples of how I'm doing things at the moment. This is my player struct, holding information of the sprite. public struct PlayerData { public Vector2 Position; // where to draw the sprite public Vector2 Direction; // travel direction of sprite public float Angle; // rotation of sprite public float Velocity; public float Acceleration; public float Decelleration; public float RotationAcceleration; public float RotationDecceleration; public float TopSpeed; public float Scale; } This is how I'm currently handling thrusting / braking (when pressing/releasing key up) (simplified, removed some bounds checking etc): player.Velocity += player.Acceleration * 0.1f; player.Velocity -= player.Acceleration * 0.1f; And when I rotate the sprite left and right: player.Angle -= player.RotationAcceleration * 0.1f; player.Angle += player.RotationAcceleration * 0.1f; This runs in the update loop, keeps the direction updated and updates the position: Vector2 up = new Vector2(0f, -1f); Matrix rotMatrix = Matrix.CreateRotationZ(player.Angle); player.Direction = Vector2.Transform(up, rotMatrix); player.Direction *= player.Velocity; player.Position += player.Direction; I am following along various beginner tutorials and haven't found any describing this, but I have tried some on my own without success. Do I need to change my velocity and acceleration fields to Vectors instead of floats to accomplish this type of movement? I realise my Angle and the Direction vector is currently tied together and I need to disconnect these somehow to be able to rotate freely without changing the direction of the movement, but I can't quite figure out how to do this while keeping the acceleration/decceleration functional. Would appreciate an explanation rather than pure code samples. Thanks,

• Replacing image in sprite - cocos2d game development of iphone

  - by sagar

  I want to change the sprite image. Say for example. mainSprite=[Sprite spriteWithFile:@"redFile.png"]; [self addChild:mainSprite]; Here, Sprite is already added to a layer. I have mainSprite (pointer) which can access it. If I change [mainSprite setOpacity:150]; it works perfectly. But Here I want to change the sprite image instead of opacity. But Don't know how? Thanks in advance for helping me. Sagar

• Optimal sprite size for rotations

  - by Panda Pajama

  I am making a sprite based game, and I have a bunch of images that I get in a ridiculously large resolution and I scale them to the desired sprite size (for example 64x64 pixels) before converting them to a game resource, so when draw my sprite inside the game, I don't have to scale it. However, if I rotate this small sprite inside the game (engine agnostically), some destination pixels will get interpolated, and the sprite will look smudged. This is of course dependent on the rotation angle as well as the interpolation algorithm, but regardless, there is not enough data to correctly sample a specific destination pixel. So there are two solutions I can think of. The first is to use the original huge image, rotate it to the desired angles, and then downscale all the reaulting variations, and put them in an atlas, which has the advantage of being quite simple to implement, but naively consumes twice as much sprite space for each rotation (each rotation must be inscribed in a circle whose diameter is the diagonal of the original sprite's rectangle, whose area is twice of that original rectangle, supposing square sprites). It also has the disadvantage of only having a predefined set of rotations available, which may be okay or not depending on the game. So the other choice would be to store a larger image, and rotate and downscale while rendering, which leads to my question. What is the optimal size for this sprite? Optimal meaning that a larger image will have no effect in the resulting image. This is definitely dependent on the image size, the amount of desired rotations without data loss down to 1/256, which is the minimum representable color difference. I am looking for a theoretical general answer to this problem, because trying a bunch of sizes may be okay, but is far from optimal.

• Make a basic running sprite effect

  - by PhaDaPhunk

  I'm building my very first game with XNA and i'm trying to get my sprite to run. Everything is working fine for the first sprite. E.g : if I go right(D) my sprite is looking right , if I go left(A) my sprite is looking left and if I don't touch anything my sprite is the default one. Now what I want to do is if the sprite goes Right, i want to alternatively change sprites (left leg, right leg, left leg etc..) xCurrent is the current sprite drawn xRunRight is the first running Sprite and xRunRight1 is the one that have to exchange with xRunRight while running right. This is what I have now : protected override void Update(GameTime gameTime) { float timer = 0f; float interval = 50f; bool frame1 = false ; bool frame2 = false; bool running = false; KeyboardState FaKeyboard = Keyboard.GetState(); // Allows the game to exit if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); if ((FaKeyboard.IsKeyUp(Keys.A)) || (FaKeyboard.IsKeyUp(Keys.D))) { xCurrent = xDefault; } if (FaKeyboard.IsKeyDown(Keys.D)) { timer += (float)gameTime.ElapsedGameTime.TotalMilliseconds; if (timer > interval) { if (frame1) { xCurrent = xRunRight; frame1 = false; } else { xCurrent = xRunRight1; frame1 = true; } } xPosition += xDeplacement; } Any ideas...? I've been stuck on this for a while.. Thanks in advance and let me know if you need any other part from the code.

• Sprite batching seems slow

  - by Dekowta

  I have implemented a sprite batching system in OpenGL which will batch sprites based on their texture. How ever when I'm rendering ~5000 sprites all using the same texture i'm getting roughly 30fps. The process is as followed create sprite batch which also create a VBO with a set size and also creates the shaders as well call begin and initialise the render mode (at the moment just setting alpha on) call Draw with a sprite. This checks to see if the texture of the sprite has already been loaded and if so it just creates a pointer to the batch item and adds the new sprite coords. If not then it creates a new batch item and adds the sprite coords to that; it adds the batch item to the main batch. if the max sprite count is reached render will be called call end which calls render to render the left over sprites in the batch. and also resets the buffer offset render loops through each item in the batch and will bind the texture of the batch item, map the data to the buffer and then draw the array. the buffer will then be offset by the amount of sprites drawn. I have a feeling that it could be the method i'm using to store the batched sprites or it could be something else that i'm missing but I still can work it out. the cpp and h files are as followed http://pastebin.com/ZAytErGB http://pastebin.com/iCB608tA On top of this i'm also getting a weird issue where then two sprites are batched on after the other the second sprite will use the same coordinates as the last. And then when one if drawn after it is fine. I can't seem to find what is causing this issue. any help would be appreciated iv been sat trying to work this all out for a while now and cant seems to put my finger on what's causing it all.

• Tool to convert a series of image into a single sprite sheet

  - by senbei

  Are there any known tools that can take a serie of pictures and generate a single sprite sheet from them? (ie. place all the images into a single image, one after the other). I have found some very basic software doing this, but I am looking for one that is able to detect duplicate frames as well as outputting some kind of data structure that allow me to programatically retrieve the coordinate of each frame on the generated image. I need this to convert existing animations with many duplicate frames and I am a bit surprised that there is no standard software to do this, as most infos you can find on the web about this is people doing this completely manually.. Any recommendations?

• Overlay 2d weapon sprite over character sprite ?

  - by Mr.Gando

  Hello, I'm working on a game where my character needs to be able to have different weapons. For that I think that somehow overlaying the weapon over the moving sprite would be the correct choice, but I'm not sure about how could I do this. Assuming my Character spritesheet looks like this: And my preliminar weapon spritesheet ( haven't decided on a fixed square size for the weapon yet ), looks like this: How would you make the overlay to set the weapon correctly over the character hand for each of his frames? I know that one way would be just to have a weapon frame the same size as my character sprites, and overlay those too, but I think that if the game has way too much weapons (say 15 different kinds of one hand weaps) this could get pretty insane ( having one weapon sprite sheet the same size as the character sprite sheet for each type of weapon ) Do you guys have any advice on how to implement this? (supporting overlaying the weapon sprites over the character sprites) Thanks!

• how to re-use a sprite in cocos2d-x

  - by zinking

  some times it takes time to create the sprite structures in the scene, I might need to setup structures inside this sprite to meet requirement, thus I would hope to reuse such structures with the game again and again. I tried that, remove the child from parent, detach it from parent , clean parent with the sprite. but when I try to add the sprite to another scene, it's just wont pass the assertion that the sprite already have parent did I miss some step ? add an example: I have a sprite A which involves of quite a few steps to construct, so I used it in scene A layer A, and then I want to use it in scene A layer B, scene B layer A1 etc..... generally speaking I don't want to reconstruct the sprte again.

• Sprite rotation

  - by Kipras

  I'm using OpenGL and people suggest using glRotate for sprite rotation, but I find that strange. My problem with it is that it rotates the whole matrix, which sort of screws up all my collision detection and so on and so forth. Imagine I had a sprite at position (100, 100) and in position (100, 200) is an obstacle and the sprite's facing it. I rotate the sprite away from the obstacle and when move upwards my y axis, even though the projection shows like it's going away from the obstacle, the sprite will intersect it. So I don't see another way of a rotating a sprite and not screwing up all collision detection other than doing mathematical operations on the image itself. Am I right or am I missing something?

• moving a sprite causes jerky movement

  - by mac_55

  I've got some jerky movement of my sprite. Basically, when the user touches a point on the screen, the sprite should move to that point. This is working mostly fine... it's even taking into account a delta - because frame rate may not be consistant. However, I notice that the y movement usually finishes before the x movement (even when the distances to travel are the same), so it appears like the sprite is moving in an 'L' shape rather than a smooth diagonal line. Vertical and horizontal velocity (vx, vy) are both set to 300. Any ideas what's wrong? How can I go about getting my sprite to move in a smooth diagonal line? - (void)update:(ccTime)dt { int x = self.position.x; int y = self.position.y; //if ball is to the left of target point if (x<targetx) { //if movement of the ball won't take it to it's target position if (x+(vx *dt) < targetx) { x += vx * dt; } else { x = targetx; } } else if (x>targetx) //same with x being too far to the right { if (x-(vx *dt) > targetx) { x -= vx * dt; } else { x = targetx; } } if (y<targety) { if (y+(vy*dt)<targety) { y += vy * dt; } else { y = targety; } } else if (y>targety) { if (y-(vy*dt)>targety) { y -= vy * dt; } else { y = targety; } } self.position = ccp(x,y); }

• Scaling sprite velocity / co-ordinatesin Android

  - by user22241

  I'm trying to find the answer to a question that I've had for a long time, but am having trouble finding it! I hope someone can help :-) I'm trying to find information on how to scale sprite velocity / movement / co-ordinates. What I mean by this is how do I get a sprite to move at the same speed relative to the screen size / DPI so that it takes the same amount of real-time to get from one side of the screen to the other? All of the posts pertaining to sprite scaling that I can find on the various forums relate to the size of the sprite, but this part of it I'm OK with so far, it's just that when I move a sprite, it kind of gets there at different speed depending on the dpi / resolution of the device. I hope I'm making sense. This is the code I have so far, instead of using explicit amounts, like 1, I'm using something like the following: platSpeedFloat= (1 * (dpi/160)); //Use '1' so on an MDPI screen, the sprite will move by 1 physical pixel Then basically what I'm doing is something like this: (all varialble previously declared) platSpeedSave+=platSpeedFloat; //Add the platSpeedFloat value to the current platSpeedSave value platSpeed=(int) platSpeedSave; //Cast to int so it can be checked in the following statement if (platSpeed==platSpeedSave) //Check the casted int value to float value stored previoiusly {floorY=floorY-platSpeed; //If they match then change the Y value platSpeedSave=0;} //Reset Would be grateful if someone could assists - hope I'm making sense. The above doesn't seems to work the sprite moves 'faster' on lower DPI screens. Thanks

• Flex Sprite ButtonMode

• android - How to draw only the sprite from an image on the canvas

  - by user1320494

  this is the first time for me here, so I hope I'm doing this right :) My question is the following: how do I draw the sprite from an image on the canvas, so that I don't get the entire (squared) image to show, but only the parts of the image I want (= the sprite). For example, I have an image of a robot on a white background and I only want to see the robot, and not the white background. I hope someone here can help me with this problem, because it's giving me headaches of not knowing how to do it :P
