[Solved] Detect when player hits the ground

[DavidM]

I'm trying to call a function whenever the player, holding a specific item, falls (hits) the ground. The closest I can get is to override Item#onUpdate and detect whether the player is on the ground, but this triggers every tick when the player is on the ground instead of the tick when the player hits the ground.

@Override
public void onUpdate(ItemStack stack, World world, Entity entity, int itemSlot, boolean isSelected) {
  super.onUpdate(stack, world, entity, itemSlot, isSelected);

  if (world.isRemote || !(entity instanceof EntityPlayer)) return;
  EntityPlayer player = (EntityPlayer) entity;

  if (isSelected) {
  	if (player.onGround) {
		someFunction();
	}
  }
}

 

I was thinking the record whether the player is on the ground, and check to recorded value during the tick after to see if onGround is true this tick while onGround is false the previous tick, but I haven't implement it yet.
