Composite Actors
- Function AddCompositeChild(actor, child_actor, t_matrix)
Adds a child Actor to a composite actor.
Returns the child index in the composite actor.
NOTE: Reference the included Composite Demo for an example
See also
- Function GetCompositeChildCount(actor)
Returns the number of child actors in a composite actor
- Function GetCompositeChild(actor, child_index)
Returns the actor stored as the child actor at a given index in a composite actor
- Function GetCompositeChildIndex(actor, child_index)
Returns the index an actor is stored at in a composite actorr
- Sub RemoveCompositeChild(actor, child_index)
Removes the actor stored as a child at the given index in a composite actor
NOTE: This will change the index of all the remaining child actors
See also
- Function GetCompositeChildTransform(actor, child_index, t_matrix)
Stores the transform from composite actor to the child index shape in t_matrix.
- Function GetCompositeAABB(actor, t_matrix, ByRef min_x, ByRef min_y, ByRef min_z, ByRef max_x, ByRef max_y, ByRef max_z)
Returns the bounding box of a composite actor
t_matrix will store the transform for the bounding box.
- Sub RecalculateCompositeAABB(actor)
Recalculates the bounding box for a composite actor.
- Sub GenerateCompositeAABBFromChildren(actor)
Generates a bounding box based on the child actorsr.
- Sub CalculateCompositePrincipalTransform(actor, ByRef masses, principal_matrix, ByRef x, ByRef y, ByRef z)
Calculates the center of mass and principal intertia axes for a composite actor.
Parameters:
- masses - An array with masses for each child in the compound shape.
- principal_matrix - This will be set to principal axis transform (x, y, z) - Inertia

- Sub UpdateCompositeChildTransform(actor, child_index, t_matrix, recalc_flag)
Sets a new child transform and updates dynamic AABB tree.
- Function GetCompositeUpdateRevision(actor)
Returns a counter that increments when the composite actor shape is modifed.
