[1.12.2] Block Collision

[Chokearth]

Hello, I make a block like a fence, but when I approach, the block pushes me away.

Did you look at the code for BlockFence? Did you look at what they do for collision bounding box?

Yes I looked.

Could this be your problem?

[Chokearth]

No I change the value in the constructor. 

[Chokearth]

Okay, I found, I was using isFullBlock () instead of isFullCube ().
