Subject: [PATCH] Cap Entity Collisions
|
|
|
|
Limit a single entity to colliding a max of configurable times per tick.
|
|
This will alleviate issues where living entities are hoarded in 1x1 pens
|
|
|
|
This is not tied to the maxEntityCramming rule. Cramming will still apply
|
|
just as it does in Vanilla, but entity pushing logic will be capped.
|
|
|
|
You can set this to 0 to disable collisions.
