PrismaticJoint class

A prismatic joint. This joint provides one degree of freedom: translation along an axis fixed in bodyA. Relative rotation is prevented. You can use a joint limit to restrict the range of motion and a joint motor to drive the motion or to model joint friction.

Properties

anchorA → Vector2
Get the anchor point on bodyA in world coordinates.
no setterinherited
anchorB → Vector2
Get the anchor point on bodyB in world coordinates.
no setterinherited
bodyA ↔ Body
getter/setter pairinherited
bodyB ↔ Body
getter/setter pairinherited
collideConnected → bool
Get collide connected. Note: modifying the collide connect flag won't work correctly because the flag is only checked when fixture AABBs begin to overlap.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
isActive → bool
Short-cut function to determine if either body is inactive.
no setterinherited
islandFlag ↔ bool

maxMotorForce ↔ double
Set the maximum motor force, usually in N.
getter/setter pair
motorSpeed ↔ double
Get the motor speed, usually in meters per second.
