This function is not supported in earlier versions.

Creates a constraint joint between two bodies. A WeldJoint essentially glues two bodies together. The constraint is a bit soft, however, due to Box2D's iterative solver.

O.png Making changes to a World is not allowed inside of the beginContact, endContact, preSolve, and postSolve callback functions, as BOX2D locks the world during these callbacks.

boolean collideConnected (false)
Specifies whether the two bodies should collide with each other.

Returns

WeldJoint joint
The new WeldJoint.
