Unigine::JointPrismatic Class
| Header: | #include <UniginePhysics.h> |
| 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++)
include <UniginePhysics.h>
/* .. */
JointPrismaticPtr joint = JointPrismatic::create(b0, b1);
// setting joint axis coordinates
joint->setWorldAxis(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#
