Detailed Description
Mouse joint definition.This requires a world target point, tuning parameters, and the time step.
Member Data Documentation
The initial world target point.
This is assumed to coincide with the body anchor initially.
| float32 b2MouseJointDef::maxForce |
The maximum constraint force that can be exerted to move the candidate body.
Usually you will express as some multiple of the weight (multiplier * mass * gravity).
