awt

I am currently working on a simple top down shooter. The object is a ball that slides around the screen, and I am trying to make a sort of wet-dragging affect. I am using Java Swing and just the default Graphics2d lib inside. This is what I have: and this is my goal: I need to know how I can make a curved line that has the ability to change alpha at the trailing end. I have searched online but I can only find non-dynamic solutions. (The tail needs to update as the player moves across the screen.) A simple solution might be to simple add each point to a List of Point s which before the player

I'm doing the following call in my code: ... setLayout(null); ... I'm trying to place a button and a textfield by specifying their x and y coordinates. The problem when I run the program (either with Eclipse or BlueJ) is that I need to run on the panel up to the position of the button and the textfield in order to see respectively the button and the textfield. When I find the textfield, it is small. Only when I start writing it assumes the size I specified. Does anyone know how to solve it? Avoid setLayout (null), unless you have a very good reason for it. You can learn about layout managers

How to draw heart using java awt libaray? I am using Java AWT Libaray and I need to draw a heart for my game. How can I do this using AWT? Here what I was thinking: may be use g.fillArc() ? but then if I make two curves at top than how to make a triangle at button? Would that be g.fillPolygon() ? g.fillArc(x, y, 20,20, 60, 60); //so this will be left curve g.fillArc(x+20, y, 20,20, 60, 60); //so right curve? //button triangle? I was wondering if any one is experence in awt and could show me how to do this? Had to write this code for something I'm doing and it works well enough. Draws a

I have a specific "problem" with a game I'm creating for class. The game is an implementation of "Break it". To move the platform at the bottom I just used a key listener. The problem is that after the first key press there is a short "lag" or "stutter" before the platform starts moving. How could I prevent this to get a smooth response? Is there another way than KeyListener? KeyBindings? Here is the key listener implementation private class KeyControl implements KeyListener { private int dx = 20; public void keyPressed(KeyEvent e) { if(e.getKeyCode() == KeyEvent.VK_RIGHT) { if(dx < 0 ) dx =

So I created a simple simple simulation where squares are spawned randomly with random vectors and bounce of the edges of the window. I wanted it to take into account the window being resized. So that if I change the dimensions of the window from 600x600 to 1200x600 the squares will bounce of the new border rather than 600x600. I tried doing getWidth() getHeight() but it would return 0. So I put it in the pain() (since it gets called on window resize) method and saved the return values as local variables. But I cannot call getjpWidth() from the Rect class. So basically what I need is to get

I know this is probably close to a duplicate of this thread: Animated GIF in Splashscreen But since it seems unanswered and I can't comment on it or anything I'm sorry to repost this but it would be awesome if someone could give me an answer. I am making a game and this game takes quite a lot of time to start. Therefore I want to give the user feedback during the loading screen so he knows the application hasn't crashed. That's why I use the SplashScreen API from java 7. In eclipse, when I run my application using the following configuration in VM Arguments, SplashScreen.getSplashScreen()
