[1.12.2] Checking if the player can place a block using PlayerInteractEvent.RightClickBlock

[tuku747]

Is there a way to tell if the item used during PlayerInteractEvent is going to result in a block being placed in the world? The issue with PlayerInteractEvent.RightClickBlock is that it's called on the client even when the player is too close to the clicked block for a new block to be placed. I need to check before BlockEvent.PlaceEvent is triggered because I want to prevent the ItemStack's count from decreasing.

I tried using world.mayPlace() but it doesn't seem to detect if the player is standing in the way. I'm using this method in PlayerInteractEvent.RightClickBlock:

Block block = Block.getBlockFromItem(event.getItemStack().getItem());
if (world.mayPlace(block, event.getPos().offset(event.getFace()), false, event.getFace(), player)) {

}

 

Alternatively, is there a reliable way to detect when an item is consumed or depleted in stack size?

Only execute on serverside then.

This causes the client and the server to desync. The item is used up on the client but still exists on the server. Is there a reliable way to update the client's hotbar?
