- Lots of itemstack cloning removed. Only clone if the item is actually moved - Return true when a plugin cancels inventory move item event instead of false, as false causes pulls to cycle through all items. However, pushes do not exhibit the same behavior, so this is not something plugins could of been relying on. - Add option (Default on) to cooldown hoppers when they fail to move an item due to full inventory - Skip subsequent InventoryMoveItemEvents if a plugin does not use the item after first event fire for an iteration

Subject: [PATCH] Fix FallingBlocks being stuck on fences
|
|
|
|
Fallingblocks would previously only check if directly beneath them a block exists. They also
|
|
hover on top of the 1.5 block tall hitbox of fences during these check. This
|
|
resulted in them always thinking they would be on air.
|
|
|
|
We now first check, if if we are already on the ground.
|
|
if not, we check if the falling block is inside of the hitbox of the block at y - 1.
