@Deltakosh: Question ... Does javascript provide a high resolution timer?
I've written a few game engines from scratch, some in C, some in Java, some in Flash. I always follow the same basic model when it comes to animations and interactive graphics. Create a basic class/structure with the following design:
void init() { /* called once, preload essential resources here */ }
void update(double time) { /* updates game/animation state using high resolution time */ }
void render(double time) { /* updates screen graphics using high resolution time */ }
void run()
{
double time;
init();
while (!done)
{
time = queryTime();
update(time);
render(time);
}
}
Time is so important to smooth animations and game state calculations. In native code Windows I use QueryPerformanceCounter()/QueryPerformanceFrequency() to perform the role of queryTime() each game loop and pass the time to update/render. In Java I use System.nanoTime().
What's the equivalent in Javascript? That is, some function like queryTime() which returns a time value with a high degree of accuracy (sub millisecond). From what I've heard the best accuracy you can get in Javascript is ~15ms ... which is horrible for animation.
Curious
