What exactly about tk2dCamera is causing you problems?
Here is my quick way for working with it:
- decide on the resolution of your game, be it 480x320, or 960x640, etc. This is your native resolution.
- make all your assets, calculations, movements, based on this resolution
- if you want to support a different resolution, make use of the overrides. Everything should *just work*.
Tip: It helps to get a hold of 2D Toolkit 2.1 Beta, it makes the overrides make a lot more sense.
