static JointPrismaticPtr create()
Constructor. Creates a prismatic joint with an anchor at the origin of the world coordinates.static JointPrismaticPtr create(const Ptr<Body> & body0, const Ptr<Body> & body1)
Constructor. Creates a prismatic joint connecting two given bodies. An anchor is placed between centers of mass of the bodies.Arguments
- const Ptr<Body> & body0 - First body to be connected with the joint.
- const Ptr<Body> & body1 - Second body to be connected with the joint.
static JointPrismaticPtr create(const Ptr<Body> & body0, const Ptr<Body> & body1, const Math::Vec3 & anchor, const Math::vec3 & size)
Constructor. Creates a prismatic joint connecting two given bodies with specified axis coordinates and an anchor placed at specified coordinates.Arguments
- const Ptr<Body> & body0 - First body to be connected with the joint.
- const Ptr<Body> & body1 - Second body to be connected with the joint.
- const Math::Vec3 & anchor - Anchor coordinates.
- const Math::vec3 & size - Axis coordinates.
Ptr<JointPrismatic> cast(const Ptr<Joint> & joint)
Casts a JointPrismatic out of the Joint instance.Arguments
- const Ptr<Joint> & joint - Joint instance.
Return value
JointPrismatic.void setAxis0(const Math::vec3 & axis0)
Sets a joint axis in the local coordinates of the first body.Arguments
- const Math::vec3 & axis0 - Joint axis in the coordinates of the first body.
Math::vec3 getAxis0()
Returns the joint axis in the local coordinates of the first body.Return value
Joint axis in the coordinates of the first body.float getCurrentLinearDistance()
Returns the current distance between the bodies.Return value
Current distance in units.float getCurrentLinearVelocity()
Returns the current velocity of the attached motor.Return value
Current velocity in units per second.void setLinearDamping(float damping)
Sets a linear damping of the joint.Arguments
- float damping - Linear damping. If a negative value is provided, 0 will be used instead.
float getLinearDamping()
Returns the linear damping of the joint.Return value
Linear damping.void setLinearDistance(float distance)
Sets a target distance of the attached spring. The spring tries to move the connected bodies so that to keep this distance between them.Arguments
- float distance - Target distance in units.
float getLinearDistance()
Returns the target distance of the attached spring. The spring tries to move the connected bodies so that to keep this distance between them.Return value
Target distance in units.void setLinearForce(float force)
Sets a maximum force of the attached motor.Arguments
- float force - Maximum force. 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. 0 means that the motor is not attached.Return value
Maximum force.void setLinearLimitFrom(float from)
Sets a low limit distance. This limit specifies how far a connected body can move along the joint axis.Arguments
- float from - Distance in units.
float getLinearLimitFrom()
Returns the low limit distance. This limit specifies how far a connected body can move along the joint axis.Return value
Low limit distance in units.void setLinearLimitTo(float to)
Sets a high limit distance. This limit specifies how far a connected body can move along the joint axis.Arguments
- float to - Distance in units.
float getLinearLimitTo()
Returns the high limit distance. This limit specifies how far a connected body can move along the joint axis.Return value
High limit distance in units.void setLinearSpring(float spring)
Sets a rigidity coefficient of the spring.Arguments
- float spring - Rigidity coefficient. If a negative value is provided, 0 will be used instead. 0 detaches the spring.
float getLinearSpring()
Returns the rigidity coefficient of the spring. 0 means that the spring is not attached.Return value
Rigidity coefficient.void setLinearVelocity(float velocity)
Sets a target velocity of the attached motor.Arguments
- float velocity - Target velocity in units per second.
