Passing elapsed time to the update function from the game loop
- by Sri Harsha Chilakapati
I want to pass the time elapsed to the update() method as this would make easy to implement the animations and time related concepts.
Here's my game-loop.
public void gameLoop(){
boolean running = true;
long gameTime = getCurrentTime();
long elapsedTime = 0;
long lastUpdateTime = 0;
int loops;
while (running){
loops = 0;
while(getCurrentTime()>gameTime && loops<Global.MAX_FRAMESKIP){
elapsedTime = getCurrentTime() - lastUpdateTime;
lastUpdateTime = getCurrentTime();
update(elapsedTime);
gameTime += SKIP_STEPS;
loops++;
}
displayGame();
}
}
getCurrentTime() method
public long getCurrentTime(){
return (System.nanoTime()/1000000);
}
update() method
long time = 0;
public void update(long elapsedTime){
time += elapsedTime;
if (time>=1000){
System.out.println("A second elapsed");
time -= 1000;
}
}
But this is printing the message for 3 seconds.
Thanks.
