JointPath Class
| Inherits: | Joint |
A path joint is used with BodyPath: it attaches an arbitrary BodyRigid to move along its path.
Notice
The path is a spline along which an object can be moved.

JointPath Class
Members
static JointPath()
Constructor. Creates a path joint with an anchor at the origin of the world coordinates.static JointPath(Body body0, Body body1)
Constructor. Creates a path joint connecting two given bodies. An anchor is placed in the center of the rigid body attached the path body.Arguments
- Body body0 - BodyRigid to be connected with the joint.
- Body body1 - BodyPath to be connected with the joint.
static JointPath(Body body0, Body body1, Vec3 anchor)
Arguments
- Body body0
- Body body1
- Vec3 anchor
JointPath cast(Joint joint)
Arguments
- Joint joint
float getCurrentLinearVelocity()
Returns the current linear velocity of the attached motor.Return value
Current linear velocity in units per second.void setLinearDamping(float damping)
Sets damping factor of linear velocities of bodies connected by the joint.Arguments
- float damping - Linear damping to be set. If a negative value is provided, 0 will be used instead.
float getLinearDamping()
Returns the current damping factor for linear velocities of bodies connected by the joint.Return value
Linear damping.void setLinearForce(float force)
Sets a maximum force of the attached motor. 0 means that the motor is not attached.Arguments
- float force - Maximum force to be set. If a negative value is provided, 0 will be used instead. 0 detaches the motor.
float getLinearForce()
Returns the maximum force of the attached motor.Return value
Maximum force.void setLinearVelocity(float velocity)
Sets a target linear velocity of the attached motor.Arguments
- float velocity - Target velocity in units per second.
float getLinearVelocity()
Returns the current linear velocity of the attached motor.Return value
Target velocity in units per second.void setRotation0(mat3 rotation0)
Sets a rotation matrix of the anchor point in a system of coordinates of the connected rigid body.Arguments
- mat3 rotation0 - Rotation matrix in the body-space coordinates.
mat3 getRotation0()
void setWorldRotation(mat3 rotation)
Sets a rotation matrix of the anchor point in the world coordinates.Arguments
- mat3 rotation - Rotation matrix in the world-space coordinates.
mat3 getWorldRotation()
