How to boost Frame Per Second?

Question

Ok I see all these games that get a good 30-60 fps. I have a game I created that is 2d with some .png images. I need to boost my fps from 16 to 30+ How would I go about this? This is how I have it set <Main Applet> -> <swing.timer(1ms)> -> Repaint() is that the only way to get good fps?

Answer 1

I actually made a game with several hundred fps, I had to slow it down though - it was ridiculous.
When you press the left key, the character would move 1 pixel per frame - and it looked like it was teleporting.
Try something like this (Note: wait is just a method I made that waits the provided amount of milliseconds):
long lastTime, nextTime;
public void capFrameRate(int time) {
  if(lastTime == 0) {
   wait(1000/time);
  else {
   nextTime = System.currentTimeMillis()-lastTime;
   if(nextTime < 1000/time) {
    wait(1000/time);
  lastTime = System.currentTimeMillis();
}It may also be because you are using png images, png usually are larger in size than jpeg (and gif, I think).
Note: it is always a good idea to load the images prior to gameplay or it will halt until the image loads.
EX: If you made a game where if you get hit by a laser, you'd blow up - the game would halt while loading the explosion for the first time.
