Unigine.JointBall Class
| Inherits from: | Joint |
This class is used to create ball joints.
Example#
The following code illustrates connection of two bodies (b0 and b1) using a ball joint.
Source code (C#)
JointBall joint = new JointBall(b0, b1);
// setting joint axis coordinates
joint.setWorldAxis(new vec3(1.0f, 0.0f, 0.0f));
// setting common joint constraint parameters
joint.setLinearRestitution(0.8f);
joint.setAngularRestitution(0.8f);
joint.setLinearSoftness(0.0f);
joint.setAngularSoftness(0.0f);
// setting angular damping
joint.setAngularDamping(16.0f);
// setting swing angular limit, in degrees
joint.setAngularLimitAngle(30.0f);
// setting twist angular limits, in degrees [-20; 20]
joint.setAngularLimitFrom(-20.0f);
joint.setAngularLimitTo(20.0f);
// setting number of iterations
joint.setNumIterations(16);See Also#

JointBall Class
Properties
vec3 WorldAxis#
The joint axis. the joint axis is calculated based on the axes of the connected bodies.
float AngularLimitTo#
The high twist limit angle. twist limit specifies how much a connected body can twist around the joint axis.
float AngularLimitFrom#
The low twist limit angle. twist limit specifies how much a connected body can twist around the joint axis.
float AngularLimitAngle#
The swing limit angle. swing limit specifies how much connected bodies can bend from the joint axis. 0 means there is no limit.
float AngularDamping#
The angular damping of the joint.
vec3 Axis1#
The axis of the second connected body.
vec3 Axis0#
The axis of the first connected body.
