Obscure detail in that if you teleport right on a chunk line, it adds +1 to your collision check and will check the unloaded neighbor. but the call to load the chunk then returned null if it was pending unload, such as the load we did in Player List However we want gen=true for players here anyways, so use getType

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.
