Entity Effects are the effects that can be applied onto entities. It can be done with the addition of pev->effects in programming or adding effects key value in any entity properties in mapping.

Programming

According to the code in const.h, these are the available effects in the vanilla game.
// entity effects
#define EF_BRIGHTFIELD 1 // swirling cloud of particles
#define EF_MUZZLEFLASH 2 // single frame ELIGHT on entity attachment 0
#define EF_BRIGHTLIGHT 4 // DLIGHT centered at entity origin
#define EF_DIMLIGHT 8 // player flashlight
#define EF_INVLIGHT 16 // get lighting from ceiling
#define EF_NOINTERP 32 // don't interpolate the next frame
#define EF_LIGHT 64 // rocket flare glow sprite
#define EF_NODRAW 128 // don't draw entity
#define EF_NIGHTVISION 256 // player nightvision
#define EF_SNIPERLASER 512 // sniper laser effect
#define EF_FIBERCAMERA 1024 // fiber camera
To use these effects, simply add the effect definition in the pev->effects argument. (e.g.: pev->effects = EF_BRIGHTLIGHT)

Mapping

Mappers can easily add effects key value to use these effects for their entities (Turn off Smart Edit first). The entities must be brushed-tied (usually starts with prefix func_ and must be tied with an origin texture, similar to doors, or else its origin will be the map origin. Example of the effects:
Entity effects #1Entity effects #1
Entity effects #4Entity effects #4
Entity effects #8Entity effects #8
Entity effects #64Entity effects #64

Do this work on point entities? If not, need to specify that it only works on brushes.

I can confirm at least EF_INVLIGHT (16) and EF_LIGHT (64) works on point entities.
It'd be useful to do further testing and create a table of which effects works on which type of entity.
