../_images/JointModifiers.png

The Joint Modifiers are shortcuts to the Motor->Enable, Range->Enable and Spring->Enable properties for Hinge and Prismatic joints.

With the Joint Modifiers you can easily toggle the use of motors, range and spring for these joints.

24.1. Motor

Select a joint, click Motor and the motor is enabled for the selected joint with a default speed. The default available force/torque is calculated by Momentum to avoid motors that has infinite force/torque.

24.2. Range

Select a joint, click Range and the Range is enabled for the selected joint with the default range of [-INF, INF]. This really means that you will not notice the Range in work until you change the range to some relevant values. The maximum available force/torque for a range is INF.

24.3. Spring

Select a joint, click Spring and the Spring is enabled for the selected joint with the default position at 0. This spring will try to move the attached rigid bodies so that the joint reaches the spring position.
