#[1.21] Adding delay to block

Fabric itself does not include APIs to schedule something in the future.
DO NOT use threads or java.util.Timer. (This can cause a crash!) Instead:
- If you are making a block do something in the future:
world.scheduleBlockTick+ overridescheduledTickin yourBlock. - If you are making a custom tickable stuff (usually block entity/entity) do something in the future/periodically: see below, but instead of Mixin just implement yourself
- If you are making a vanilla tickable thing (world, server, etc) do something in the future/periodically: use the following mixin.
@Mixin(StuffToTick.class) // ServerWorld, MinecraftServer, etc
public class StuffTimer implements StuffTimerAccess {
@Unique
private long ticksUntilSomething;
@Inject(method = "tick", at = @At("TAIL"))
private void onTick(CallbackInfo ci) { // Fix parameters as needed
if (--this.ticksUntilSomething == 0L) {
doSomething();
// If you want to repeat this, reset ticksUntilSomething here.
}
}
@Override
public void yourmod_setTimer(long ticksUntilSomething) {
this.ticksUntilSomething = ticksUntilSomething;
}
}
public interface StuffTimerAccess {
void yourmod_setTimer(long ticksUntilSomething);
}
Usage:
MinecraftServer server;
((StuffTimerAccess) server).yourmod_setTimer(100L); // do something after 100 ticks

scheduleBlockTick makes it so that the method scheduledTick will be called on your block after the desired time.
It does NOT suspend the method and wait for the time to then continue the code right at the method call.
You currently have the falling behaviour still in the same method onSteppedOn right after you schedule the block tick -- you need to move the falling behaviour from there into the scheduledTick method you have overridden
