Detailed Description

Typedef Documentation

HLIGHT

typedef int [] HLIGHT

Light handle.

Definition at line 122 of file enworld.c.

Enumeration Type Documentation

LightFlags

enum LightFlags

Enumerator
DYNAMIC	Dynamic light. Dynamic objects are included in the query. There is limit 512 dynamic lights per world and 32 per camera view. They are faster when moving and changing shape. Also they are always attached to owner entity
CASTSHADOW
CHEAP	for cheaper dynamic lights, like muzzle flashes (might use cheaper rendering method)

LightType

enum LightType

Enumerator
POINT
SPOT
DIRECTIONAL
AMBIENT
