Detailed Description
Base class for weighted animation constraints.
Constraints are primarily used to impose limits on properties of objects (e.g. position, orientation, scale) and to automate animation processes. A constrained object is an object with properties constrained by one or more weighted constraint sources.

| double GetSourceWeight | ( | const FbxObject * | pObject | ) | const |
Get the weight associated with a constraint source.
- Parameters:
-
pObject The given constraint source.
- Returns:
- The weight of the constraint source.
| virtual void Construct | ( | const FbxConstraint * | pFrom | ) | [protected, virtual] |
| virtual void ConstructProperties | ( | bool | pForceSet | ) | [protected, virtual] |
Optional property constructor override, automatically called by default constructor.
- Parameters:
-
pForceSet If the property value must be set regardless of default value.
- Remarks:
- If your object have properties, they must be initialized in this function.

Member Data Documentation
This property represents the degree of influence of a constraint from 0.0 (no influence) to 100.0 (full influence).
Default value is 100.0.
Definition at line 40 of file fbxconstraint.h.
This property controls whether the constraint is applied or not.
If the value is false the constraint will have no effect. The default value is true.
Default value is true.
Definition at line 47 of file fbxconstraint.h.
This property handles the lock state of the constraint.
When enabled, the constrained object cannot be moved away from its constrained location when the constraint is active.
Default value is false.
