Timer Based Movement with Vsync Tweening

By: Kevin Picone Added: August 23rd, 2009

Category: All, Fps, Timing

The aim of this example is to demonstrate an approach for decoupling your games logic from the host computers drawing performance, which is commonly referred to as timer based movement.

However in this approach, we're going to keep our frame based approach also. By doing this, our game logic is the virtually the same as what it would be, expect we're selectively executing the logic, and trying to tween (interpolate) the graphical output between logic refreshes.
