[Request] make b2World::DrawDebugData const #317

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
The b2World::DrawDebugData method should be made const, because drawing 
something should never modify anything. It would also be compatible with SFMLs 
const draw() method specified in the sf::Drawable interface.

Also the DrawShape method and the DrawJoint method must also be made const. In 
line 1201 in b2World.cpp, there is a pointer to a b2BroadPhase. This pointer 
also needs to be const.

This was intentional. A user implementation of b2Draw may have state. I know 
about mutable and prefer not to use it.
