BulletHingeConstraint¶

class BulletHingeConstraint¶

Bases: BulletConstraint

The hinge constraint lets two bodies rotate around a given axis while adhering to specified limits. It’s motor can apply angular force to them.

BulletHingeConstraint.__init__()¶

Creates a hinge constraint which connects one rigid body with some fixe dpoint in the world.

Constructs a hinge constraint which connects two rigid bodies.

Creates a hinge constraint in the same way as the other constructor, but uses the world as second body so that node_a is fixed to some point in mid- air for example.

Creates a hinge connecting node_a to node_b. The pivot point is the point at which the body is fixed to the constraint. In other words: It specifies where on each body the rotation axis should be. This axis is specified using axis_a and axis_b. Remember, everything is specified in the bodies own coordinate system!

BulletHingeConstraint.enable_angular_motor()¶

Applies an impulse to the constraint so that the angle changes at target_velocity where max_impulse is the maximum impulse that is used for achieving the specified velocity.

Note that the target_velocity is in radians/second, not degrees.
