C# (CSharp) Project290.Physics.Dynamics Body.ResetMassData Examples

ResetMassData() public method

This resets the mass properties to the sum of the mass properties of the fixtures. This normally does not need to be called unless you called SetMassData to override the mass and you later want to reset the mass.

public ResetMassData ( ) : void
return	void

Example #1

            // Let the world know we have a new fixture. This will cause new contacts
            // to be created at the beginning of the next time step.
