问题 I can't figure this out..hopefully someone else can. I have an image button . The hover effect works fine. However, I have the IE broken image icon over the button image. Lookie here: Funky Image Funky Image Hover As you can see...they both work except for that annoying broken image. Here's my CSS: .donate-btn{ background: transparent url(/custom/img/donate-btn.png) no-repeat; overflow:hidden; height:45px; width:210px; float:left; } .donate-btn:hover{ background: transparent url(/custom/img

问题 My game has 1000+ frames and format of sprites is Crunch because of too many sprites in this project. when I want to switch it from windows to android it takes me almost 1 day to switch (actually I don't permit it to switch completely) but switching to windows is not that much, maybe just 15 minuets. Just I want to know is it sensible or not ? and if it doesn't, is there any solution ? 回答1: I have my projects in a version control system (like SVN or Git) and have a checkout per build platform

问题 Is the only benefit of using css image sprites that there is less http requests? Or is there other benefits? Also is there an easy way of detiming which area of a sprite to show? 回答1: Like you said, one of the main advantage is to reduce the number of requests to the server, improving the response time (especially if you're loading a large amount of small images). But this is not the only reasons people use sprites. If you don't use sprites for a "mouse over" display, the user will see the

问题 I need help figuring out the rotation of a sprite with my finger. The sprite is rotating fine but on the initial touch of my finger it somehow rotates by a few degrees by itself. Also the rotations only work when the finger is rotated around the center of the sprite. I am trying to simulate the bicycle wheel and have a gear sprite and a pedal sprite as a child of the gear sprite. I want the bicycle wheel to rotate as I touch the pedal and rotate it. I haven't got that far yet. Right now I am

问题 I'm a newbie and trying to display a sprite on my iPhone screen using OpenGL ES. I know its far simpler and easier to do it with cocos2d but now I'm trying to code directly on OpenGL. Is there any simple yet efficient way to load and display sprites in OpenGL ES. What I've found until now is much much complex. :( 回答1: Here is some code to load a png from bundle: UIImage* image = [UIImage imageNamed:@"PictureName.png"]; GLubyte* imageData = malloc(image.size.width * image.size.height * 4);

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . Which are the choices I should look into for a Delphi sprite engine. I am aware of GLScene Andorra 2D anything else I am missing? It is best if it relies on OpenGL. DirectX only solutions are not very welcome. 回答1: Take a look at Asphyre. It's a 2D/3D Delphi framework that can use OpenGL, DirectX 7, DirectX 9

问题 I'm new to OpenGL and I'm teaching myself by making a 2D game for Android with ES 2.0. I am starting off by creating a "Sprite" class that creates a plane and renders a texture to it. To practice, I have two Sprite objects that are drawn alternating in the same place. I got this much working fine and well with ES 1.0, but now that I've switched to 2.0, I am getting a black screen with no errors . I'm exhausted trying to figure out what I'm doing wrong, but I have a strong feeling it has to do

问题 I am using Starling to make a really, really, really easy game - I am just trying to add a stationary sprite to the stage...and make it so that when the mouse touches the sprite...the game "stops" and a score is sent. I haven't tried implementing hitTest yet for the collision, but I have run into a sort of conflict problem where, when I comment out the line(s) that is supposed to change the cursor image (see Startup.as - stage.addEventListener(TouchEvent.TOUCH, touchHandler); and

问题 Using EaselJS, I have an animation that the user may scroll through with a custom slider. It uses 10 sprite sheets to display 152 frames of size 1924 x 1708. //images were declared above in style | var chromophoreAni0 = new Image(); | var data = { images: [chromophoreAniImage0, chromophoreAniImage1, chromophoreAniImage2, chromophoreAniImage3, chromophoreAniImage4, chromophoreAniImage5, chromophoreAniImage6, chromophoreAniImage7, chromophoreAniImage8, chromophoreAniImage9], frames: {count: 152

问题 How would one implement KeyListener so that I can create a two-player system where one person uses '.' and '/' to control a character, and the other person can use the arrow keys without them interrupting each other? The way I have it now is that when one person holds down the arrow key, their character moves, but the instant you use the other player's controls, the first person's character stops. 回答1: Create a HashMap<Int,Boolean> that marks which keys are currently pressed/depressed. Then
