Hello guys!
I've been looking on the internet now after i tried myself for 2 hours without any succes, I tryed with loops i tried with timers.. Nothing worked for me..
My problem is when you kill a monster in my game i whant the to explode.. And for that i need like 5 different pictures but i don't know how to make it like show picture 1 then sleep then show picture 2 then sleep and so on.. Cus if i just write
Well a simplish solution is to add a 'timeTillNextFrame' float variable to your class. Then every time your update function is called just minus the time since the last update from your 'timeTillNextFrame'. Then if it is less than or equal to zero change your explosion sprite.
Also, timeTillNextFrame should be measured in milliseconds.
Well what I told you was kinda a timer. I forgot that Java has timers, so you could use Java's timers, it wouldn't be as efficient because I think it makes a new thread...
This is what I was talking about, it's in C# and XNA, but hopefully you can convert.
public void Update(GameTime gameTime)
{
timeTillNextFrame -= ((float)gameTime.ElapsedGameTime.Milliseconds / 1000f); // converts milliseconds to seconds
if ( !done && timeTillNextFrame <= 0) // If its time to change the picture
{
currentFrame++;
if (currentFrame > maxFrames)
done = true;
SetGraphic(picture[currentFrame]); // This is where you would change your picture
timeTillNextFrame = 1f; // I set it to 1 so that the picture changes once every second
}
Perhaps you can't figure out how to calculate the time that has past?
Try this:
private long lastTime, currentTime;
public void Update()
{
lastTime = currentTime;
currentTime = System.currentTimeMillis();
timeTillNextUpdate -= ( (currentTime - lastTime) / 1000f); // divide by a thousand to make it into seconds (unless game is updating slowly, it will probably be a fraction of a second)
