Debug Block Collision

 It can be difficult to ensure that complex sets of block collision boxes are positioned properly.

This client-side mod makes this easier by rendering the collision/bounding boxes of blocks.

Issues should be submitted via GitHub (here), if possible, but can be submitted internally, if need be.

This mod has been released into the public domain. Use it anywhere in any way.

Color Key:

green = full collision boxes

blue = non-full collision boxes

red = bounding boxes (for blocks with no collision boxes)

Pressing F3 + the ‘Mode’ keybind (default = letter O) will toggle debug box rendering.

While rendering is enabled, pressing the ‘Mode’ keybind on its own will cycle the mode:
