1.18 Delta Time variable


Recommended Posts

How to get DeltaTime variable?  I tried to take one from the Minecraft instance and multiply by 3 (because the default is not 60 but 20 fps). This works, except that with shaders the variable becomes several times larger and the animations become too fast.

Minecraft uses what's known as a partialTick which is some value between 0-1 that represents the frames between the previous tick and the current tick. Typically, you would have the original position and the new position, and then linearly interpolate using the partialTick (usually via `Mth#lerp`). The partialTick is provided in nearly all rendering methods as a float.

I tried to do it like this, but with shaders the animations are 2x faster..

private static long LAST_TIME = 0;
public static float DELTA_TIME = 0;

public static void onRenderTick(TickEvent.RenderTickEvent event) {
        if (event.phase == TickEvent.Phase.START) {
            final long time = Util.getNanos();
            DELTA_TIME = (time - LAST_TIME) / 16666666F;
            LAST_TIME = time;
