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.
