PhysX Prismatic Joint Component
The PhysX prismatic joint component is a joint that links two actors such that they can only slide along one axis relative to each other.
Optionally, how for the joined actors can slide can be limited.
LimitMode: Specifies whether the distance of sliding is limited and how.
NoLimit: The actors can slide unlimited far. Since they will still collide with other objects, there may be no need to limit the slide distance through the joint.
HardLimit: When the actors reach the end of the joint range, they will be stopped. In this mode
SpringStiffnessis a restitution value that defines how much the actor will bounce back.
SpringDampingis a force theshold, if the actor hits the limit with less force than this, it will not bounce back, making it a bit sticky.
SoftLimit: When the actors pass the joint limits, they will not be stopped. Instead, a spring will start pulling them back together. In this mode
[0; inf]range) defines how strongly the spring will pull the actors.
SpringDampingdampens the spring, to prevent oscilation.
UpperLimit: How far the joined actors can move apart before being stopped or pulled back.
