SetModelFlag

Actor

void SetModelFlag(int flag)

void A_SetModelFlag(int flag) — Action function version for calling from StateProvider and PSprites.

Usage

Sets the MODELDEF flags of the model currently attached to the actor.

Parameters

• int flag:

The flag(s) to set on the model. Multiple flags can be combined with |. You can use any of the MDL_ constants from the list below:

MODELDEF flag name	Related ZScript constant	Description
PITCHFROMMOMENTUM	MDL_PITCHFROMMOMENTUM	Adjusts the model's pitch to match the momentum of the actor. Useful for projectiles that don't call A_FaceMovementDirection to adjust their actual pitch in flight.
IGNORETRANSLATION	MDL_IGNORETRANSLATION	Ignores the actor's color translation.
INTERPOLATEDOUBLEDFRAMES	MDL_INTERPOLATEDOUBLEDFRAMES	Smoothes model interpolation for actors that use the same frame twice in a row (for example, most of the standard Doom monsters do this in their see state).
ROTATING	MDL_ROTATING	Makes the model rotate continuously. Useful for pickup models a la Quake. Related properties must be defined AFTER this flag in MODELDEF.
NOINTERPOLATION	MDL_NOINTERPOLATION	Forces uninterpolated animation.
USEACTORPITCH	MDL_USEACTORPITCH	Model's pitch adjusts to match actor's pitch.
USEACTORROLL	MDL_USEACTORROLL	Model's roll adjusts to match actor's roll.
INHERITACTORPITCH (deprecated)	none	Model's pitch adjusts to match the actor's pitch, deprecated because of the unintended pitch inversion and bad name choice
INHERITACTORROLL (deprecated)	none	Model's roll, adjusts to match actor's roll. Same as USEACTORPITCH, deprecated because of bad name choice.
DONTCULLBACKFACES	MDL_DONTCULLBACKFACES	Forcefully disables backface culling.
FORCECULLBACKFACES	MDL_FORCECULLBACKFACES	Forcefully enables backface culling.
USEROTATIONCENTER	MDL_USEROTATIONCENTER	Makes Rotation-Center affect actor angles (the property must be set AFTER this flag to work). Useless unless any of the actor rotation flags are also used.
NOPERPIXELLIGHTING	MDL_NOPERPIXELLIGHTING	Disables per-pixel lighting on the model.
SCALEWEAPONFOV	MDL_SCALEWEAPONFOV	Scales the weapon's model along with the user's FOV to reduce distortion.
MODELSAREATTACHMENTS	MDL_MODELSAREATTACHMENTS	If the actor uses an IQM model, another model can be attached to it, provided the other model uses the same armature. For example, this can be used to hot-swap the weapon model in a character's hands. Model and index 0 is considered the base model. Attached models cannot have separate animations; they will be animated alongside the armature of the base model. Each model needs to have the same exact armature or unwanted behavior may occur. Having this flag defined takes priority over the Animation property.
CORRECTPIXELSTRETCH	MDL_CORRECTPIXELSTRETCH	By default, models stretch when their pitch or roll changes, in a way that matches aspect ratio correction. This flag disables that behavior so the model always retains the same size without any distortion. Note: Although technically a bug, the stretching can nevertheless be useful, for example, to ensure that a beam-shaped model retains the same length in map units regardless of orientation.
