Detailed Description

The base joint class. Joints are used to constraint two bodies together in various fashions. Some joints also feature limits and motors.

Member Function Documentation

◆ GetCollideConnected()

bool b2Joint::GetCollideConnected ( ) const

inline

Get collide connected. Note: modifying the collide connect flag won't work correctly because the flag is only checked when fixture AABBs begin to overlap.

The documentation for this class was generated from the following file:
