I'd like it to be so that when a player right clicks on a block, any entity on top gets bounced into the air a little bit.

It works on most entities, but for some reason it doesn't work on players.

@Override
public ActionResultType use(BlockState state, World world, BlockPos pos, PlayerEntity playerEntity, Hand hand, BlockRayTraceResult hit) {
	if (!world.isClientSide()) {
		List<Entity> entitiesToBoing = world.getEntitiesOfClass(Entity.class, new AxisAlignedBB(pos.getX(), pos.getY() + 1.0f, pos.getZ(), pos.getX() + 1.0f, pos.getY() + 2.0f, pos.getZ() + 1.0f));
		for (Entity entity : entitiesToBoing) {
			entity.setDeltaMovement(entity.getDeltaMovement().add(0.0f, 0.5f, 0.0f));
		}
	}
	return ActionResultType.SUCCESS;
}

My reckoning is that the velocity of player entities is changed after this method is called and before their positions are updated, but I don't know how to work around that for my purposes.

Does anybody know why this isn't working and what I can do to fix it?

(I'm using Forge 36.1.0 for MC 1.16.5, if that's relevant)

Player movement is controlled by the client, that is you need to set the movement on the client.

Aha, that was it. Setting hurtMarked to true if the entity was an instance of PlayerEntity did the trick.

Thank you for the help
