Subject: [PATCH] Improve Maps (in item frames) performance and bug fixes
|
|
|
|
Maps used a modified version of rendering to support plugin controlled
|
|
imaging on maps. The Craft Map Renderer is much slower than Vanilla,
|
|
causing maps in item frames to cause a noticeable hit on server performance.
|
|
|
|
This updates the map system to not use the Craft system if we detect that no
|
|
custom renderers are in use, defaulting to the much simpler Vanilla system.
|
|
|
|
Additionally, numerous issues to player position tracking on maps has been fixed.
