Native systems

Scripted systems are ordered against the engine’s own systems by name (see systems). This list is generated by scanning the engine sources for add_system calls, so it matches the code the docs were built from. It shows the systems registered with a literal name; a few are registered from tables (for example the physics and per-dimension systems) and do not appear here, but the engine’s system list prints every name at run time.

Names starting vanilla: are anchors that other systems order against (they are registered by tables the scanner does not follow).
