Remarks
Sets Constraint Angular Soft Twist Limit parameters
Parameters
| Name | Description |
|---|---|
| Accessor | Constraint accessor to change |
| bSoftTwistLimit | True is the twist limit is soft |
| TwistLimitStiffness | Stiffness of the soft Twist limit. Only used when Soft limit is on ( positive value ) |
| TwistLimitDamping | Damping of the soft Twist limit. Only used when Soft limit is on ( positive value ) |
| TwistLimitRestitution | Controls the amount of bounce when the constraint is violated. A restitution value of 1 will bounce back with the same velocity the limit was hit. A value of 0 will stop dead. |
| TwistLimitContactDistance | Determines how close to the limit we have to get before turning the joint on. Larger value will be more expensive, but will do a better job not violating constraints. A smaller value will be more efficient, but easier to violate. |
