Subject: [PATCH] limit the range at which we'll consider an attackable target
|
|
|
|
This patch aims to ensure that MCP World#getNearestAttackablePlayer
|
|
will not trigger chunk loads due to PathfinderGoalNearestAttackableTarget
|
|
performing a ray trace operation by pre-checking the maximum limit;
|
|
|
|
Given that the implementation shows that the limit should only ever
|
|
decrease when set, allowing us to skip further checks earlier on
|
|
when looking for an attackable entity
