The MaxAngle property of the HingeJoint class specifies the maximum angle, in degrees, that the hinge joint is allowed to rotate. This property is useful for constraining the movement of the joint to prevent it from exceeding a certain angle, which can be critical in maintaining the desired behavior of a physical simulation.

To use the MaxAngle property, you can set it to a desired value to limit the rotation of the hinge joint. This is typically done when configuring the joint in a physics simulation to ensure that it behaves as expected.

Example usage:

HingeJoint hingeJoint = new HingeJoint();
hingeJoint.MaxAngle = 90.0f; // Set the maximum angle to 90 degrees
