$collisionjoints
From Valve Developer Community
Contents
The QC command $collisionjoints is used to define a collision mesh made up of multiple independent parts, either for a ragdoll or for an animated object. If your model has no moving parts that need to collide, use $collisionmodel instead.
A ragdoll can have up to 32 separate parts (i.e. 32 bones can be simulated, 24 on older versions of source). The limit for an animated model is unknown.
Tip:Use vcollide_wireframe 1 to view collision meshes in-game.Syntax
$collisionjoints <collision mesh SMD/DMX> { <options> }
Options
- All
$collisionmodeloptions, except$concave -
Confirm:Is $masscenter allowed? - $concaveperjoint
- Permit concave collision geometry for individual bones.
- $rootbone <string|bone>
- Overrides the collision mesh's root bone.
- $jointskip <string|bone>
- Eliminates a joint in the skeleton that you don't want to use in collisions.
-
$jointmerge <string|bone1> <string|bone2> - Merges the vertex assignments for two joints.
-
$jointconstrain <string|bone> <axis> <allow_option> <min_angle> <max_angle> <friction> - Limits of the a bone's movement relative to its parent bone. See $jointconstrain for a full description.
-
$jointinertia <string|bone> <float|scale> - Per-bone
$inertia. -
$jointdamping <string|bone> <float|scale> - Per-bone
$damping. -
$jointrotdamping <string|bone> <float|scale> - Per-bone
$rotdamping. -
$jointmassbias <string|bone> <float|bias> - Mass is automatically distributed by volume, this lets you bias it per-bone.
-
$noselfcollisions - Disables collisions between bones in the same collision model for performance.
-
Warning: Results in arms clipping through torsos and other weirdness if used improperly! -
$jointcollide <string|bone1> <string|bone2> - If any
$jointcollidepairs are specified, only those joints collide with each other. -
$animatedfriction <float|FrictionTimeIn> <float|FrictionTimeOut> <float|FrictionTimeHold> <float|MinAnimatedFriction> <float|MaxAnimatedFriction> - Used to animate the amount of friction on joints over time.
