Hey, I want to implement a top-down camera as used in games like SimCity etc.
The game will be for mobile, so the camera needs to be controlled by touchscreen drags.
As an extension I will may need a zoom gesture.
I thought this would be a common concept and it should have been done somewhere, but I couldn't find any tutorial or example code.
Do you know any example code or do you have any tips on how to go about this?
