class: PrismaticJoint

[18:7] extends: Joint

Wraps jbox2d's PrismaticJoint (com.almasb.fxgl.physics.box2d.dynamics.joints.PrismaticJoint). Provides one degree of freedom: translation along an axis fixed in bodyA. Relative rotation is prevented. Supports an optional joint limit to restrict the range of motion and a joint motor to drive the motion or model joint friction.

Methods

PrismaticJoint ()

Empty default constructor; populated by adopt.
adopt (object Ajo)

Wraps an existing PrismaticJoint AussomJavaObject.
getLocalAnchorA ()

Returns the local anchor on body A as a Vec2 wrapper.
getLocalAnchorB ()

Returns the local anchor on body B as a Vec2 wrapper.
getLocalAxisA ()

Returns the local translation axis in body A as a Vec2 wrapper.
getReferenceAngle ()

Returns the reference angle (radians) between the bodies.
getJointTranslation ()

Returns the current joint translation, usually in meters.
getJointSpeed ()

Returns the current joint speed.
isLimitEnabled ()

Returns whether the joint limit is enabled.
enableLimit (bool Flag)

Enables or disables the joint limit.
getLowerLimit ()
