What Is the Proper Way of Speeding up the Entire Game?

I’m creating an evolution simulator using cocos2d-x, which uses the physics engine extensively. As you can guess, I need to control the speed of the simulation.

In the scene where I want to control the speed, I’d set the Director’s Scheduler’s time scale along with PhysicsWorld’s speed, like this:


However, settings the SPEED too high (e.g. 10) would cause weird behaviors to happen - such as objects getting inside static objects. I only apply force and impulse to control the motion of objects.

I have few questions:

  • Am I doing anything wrong here?
  • Is there a better way to control the speed of the entire scene?
  • Is there a limit to the speed I can set before the system breaks down?

I’d also like to know if I can make cocos2d-x calculate a specific amount of game steps before rendering. So, let’s say, the simulation will reach a specific state after a specific number of game steps - can I just make cocos2d-x calculate the steps and reach that state as fast as possible?
