b2Body.prototype.GetLinearVelocity() should not return a reference to the b2Body's data member #26

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
The data member returned, m_linearVelocity, is an object so any changes to it ( 
such as GetLinearVelocity().Normalize() ) will alter the b2Body's data member 
directly. 

GetLinearVelocity() should return a copy of m_linearVelocity.

SetLinearVeloity() should be used to modify m_linearVelocity.

What version of the product are you using? On what operating system?
