Unigine.JointPrismatic Class
| Inherits from: | Joint |
This class is used to create prismatic joints.
Example#
The following code illustrates connection of two bodies (b0 and b1) using a prismatic joint.
Source code (C#)
JointPrismatic joint = new JointPrismatic(b0, b1);
// setting joint axis coordinates
joint.setWorldAxis(new vec3(0.0f, 0.0f, 1.0f));
// setting common joint constraint parameters
joint.setLinearRestitution(0.4f);
joint.setAngularRestitution(0.4f);
joint.setLinearSoftness(0.4f);
joint.setAngularSoftness(0.4f);
// setting linear damping
joint.setLinearDamping(4.0f);
// setting linear limits [-1.5; 1.5]
joint.setLinearLimitFrom(-1.5f);
joint.setLinearLimitTo(1.5f);
// setting number of iterations
joint.setNumIterations(16);See Also#

JointPrismatic Class
Properties
float CurrentLinearVelocity#
The current velocity of the attached motor.
float CurrentLinearDistance#
The current distance between the bodies.
mat3 WorldRotation#
The Returns a rotation matrix of the anchor point in the world system of coordinates.
mat3 Rotation1#
The Returns a rotation matrix of the anchor point in a system of coordinates of the second connected body.
mat3 Rotation0#
The Returns a rotation matrix of the anchor point in a system of coordinates of the first connected body.
float LinearVelocity#
The target velocity of the attached motor.
float LinearSpring#
The rigidity coefficient of the spring. 0 means that the spring is not attached.
float LinearLimitTo#
The high limit distance. this limit specifies how far a connected body can move along the joint axis.
float LinearLimitFrom#
The low limit distance. this limit specifies how far a connected body can move along the joint axis.
float LinearForce#
The maximum force of the attached motor. 0 means that the motor is not attached.
float LinearDistance#
The target distance of the attached spring. the spring tries to move the connected bodies so that to keep this distance between them.
float LinearDamping#
The linear damping of the joint.
vec3 WorldAxis#
The joint axis in the world coordinates.
vec3 Axis0#
The joint axis in the local coordinates of the first body.
