From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Spottedleaf Date: Wed, 15 Apr 2020 17:56:07 -0700 Subject: [PATCH] Don't run entity collision code if not needed Will not run if: Max entity cramming is disabled and the max collisions per entity is less than or equal to 0. Entity#isPushable() returns false, meaning all entities will not be able to collide with this entity anyways. The entity's current team collision rule causes them to NEVER collide.
