- Public Attributes inherited from b2JointDef
b2JointType type
 The joint type is set automatically for concrete joint types.
void * userData
 Use this to attach application specific data to your joints.
 The first attached body.
 The second attached body.
bool collideConnected
 Set this flag to true if the attached bodies should collide.

Detailed Description

Mouse joint definition. This requires a world target point, tuning parameters, and the time step.

Member Data Documentation

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).

b2Vec2 b2MouseJointDef::target

The initial world target point. This is assumed to coincide with the body anchor initially.
