Subject: [PATCH] Optimize Collision to not load chunks
|
|
|
|
The collision code takes an AABB and generates a cuboid of checks rather
|
|
than a cylinder, so at high velocity this can generate a lot of chunk checks.
|
|
|
|
Treat an unloaded chunk as a collision for entities, and also for players if
|
|
the "prevent moving into unloaded chunks" setting is enabled.
|
|
|
|
If that serting is not enabled, collisions will be ignored for players, since
|
|
movement will load only the chunk the player enters anyways and avoids loading
|
|
massive amounts of surrounding chunks due to large AABB lookups.
