A set of bitflags for configuring client-side visual effects.

Flags

#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

EF_BRIGHTFIELD : [1]

The "pollen" or "firefly" particles that appear when a monster is placed inside a wall.

EF_MUZZLEFLASH : [2]

A single-frame elight with the RGB(255,192,64) at attachment 0.

EF_BRIGHTLIGHT : [4]

Emits a dlight of RGB(250,250,250) and a random radius of 400 to 431 from the origin.

EF_DIMLIGHT : [8]

Emits a dlight of RGB(100,100,100) and a random radius of 200 to 231 from the origin.

EF_INVLIGHT : [16]

Get MDL lighting from the ceiling instead of from the floor. This has no effect if the model is currently receiving sunlight from a light_environment. Keep in mind that only world brushes (including func_group and func_detail) contribute to MDL lighting.

EF_NOINTERP : [32]

Don't interpolate on the next frame.

Bug:Causes crashes^{[citation needed]}.

If used on a model entity using a SPR, allows framerates above 10 Hz.

EF_LIGHT : [64]

Emits a dlight of RGB(100,100,100) and a radius of 200 from the entity origin, and render sprites/animglow01.spr using glow rendermode if present.

EF_NODRAW : [128]

Entity is completely ignored by the client, and stops drawing the entity.

Important:Can cause prediction errors if a player proceeds to collide with it on the server.

Confirm:Do flags 256, 512, and 1024 work in all games, or only Deleted Scenes?

FGD entries

These can either be added individually to an entity as needed, or made a BaseClass at the top of the FGD to be inherited. Note that several entities override this keyvalue; for example, the MonsterInit() run as part of most monsters' spawn function resets this key to 0, disabling any user-set values.
