Physics: Joints

[eprikazchikov]

Is your feature request related to a problem? Please describe.

This issue is a continuation of #64 issue. In this part must be implemented joints and forces for the physics module.

Describe the solution you'd like

Additional components must be implemented

• Joint - Is the base class for all joints.
• HingeJoint - The HingeJoint groups together 2 rigid bodies, constraining them to move like connected by a hinge.
• SpringJoint - The spring joint ties together 2 rigid bodies, spring forces will be automatically applied to keep the object at the given distance.
• FixedJoint - The Fixed joint groups together 2 rigidbodies, making them stick together in their bound position.

Describe alternatives you've considered
