accumulatedAcc.add(force.multiply(inverseMass));

which tends to make code much more verbose and less clear (particularly in some

of the very complex collision response algorithms where we saw many operators in a

single line).

On the other hand, in ActionScript, once you’ve decided to make a method call,

there is no additional penalty for having virtual methods. That means structures such

as the polymorphic

ContactGenerator and ForceGenerator could be replicated in

various kinds of RigidBody, Particle,orevenContact—classes for which I did not

use virtual methods in C++. This makes some kinds of programming much clearer.
