blaze.dynamics.joints.prismaticJoint

class PrismaticJointDef : blaze.dynamics.joints.joint.JointDef;

Prismatic joint definition. This requires defining a line of motion using an axis and an anchor point. The definition uses local anchor points and a local axis so that the initial configuration can violate the constraint slightly. The joint translation is zero when the local anchor points coincide in world space. Using local anchors and a local axis helps when saving and loading a game.

this(Body body1, Body body2, bVec2 anchor, bVec2 axis);

Initialize the bodies, anchors, axis, and reference angle using the world anchor and world axis.

bVec2 localAnchor1 ;

The local anchor point relative to body1's origin.

bVec2 localAnchor2 ;

The local anchor point relative to body2's origin.

bVec2 localAxis1 ;

The local translation axis in body1.

float referenceAngle ;

The constrained angle between the bodies: body2_angle - body1_angle.

bool enableLimit ;

Enable/disable the joint limit.

float lowerTranslation ;

The lower translation limit, usually in meters.

float upperTranslation ;

The upper translation limit, usually in meters.

bool enableMotor ;

Enable/disable the joint motor.

float maxMotorForce ;

The maximum motor torque, usually in N-m.

float motorSpeed ;

The desired motor speed in radians per second.

class PrismaticJoint : blaze.dynamics.joints.joint.Joint;

A prismatic joint. This joint provides one degree of freedom: translation along an axis fixed in body1. 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.

float jointTranslation ();

Get the current joint translation, usually in meters.

float jointSpeed ();

Get the current joint translation speed, usually in meters per second.

bool isLimitEnabled ();

Is the joint limit enabled?

void enableLimit (bool flag);

Enable/disable the joint limit.

float lowerLimit ();

Get the lower joint limit, usually in meters.

float upperLimit ();

Get the upper joint limit, usually in meters.

void limits (float lower, float upper);

Set the joint limits , usually in meters.

bool isMotorEnabled ();

Is the joint motor enabled?

void enableMotor (bool flag);

Enable/disable the joint motor.

void motorSpeed (float speed);

Set the motor speed, usually in meters per second.

float motorSpeed ();

Get the motor speed, usually in meters per second.

void maxMotorForce (float force);

Set the maximum motor force, usually in N.

float motorForce ();

Get the current motor force, usually in N.
