So I’ve decided that I want an iPad 2 but in order to help my inner bank manager be happy with this decision I figured it’s probably a good idea to make a game for it so in order to do this I’m putting together a bunch of prototypes.
One of these involves a tank however I’m having a bit of trouble getting my head around the controls, what I have implemented is a multi-touch trackbar component. The idea is that I want the tank to be controlled in a similar fashion (albeit naturally simplified) where the player will use two fingers to control the separate tracks. Push both fingers forward for full movement, push one forward to turn push one forward and one back for sharp turn etc
Here are some images to help illustrate this better:
The first image shows the control in its idle state and the second image shows it in a sharp turn to the left.
As you can see, each control can be pushed forward between 0 and 1 and pulled backwards between 0 and -1
Yes that little green box is the tank 
The blue bar is the turret, controlled separately and already working.
Any ideas on how this could be done? [import]uid: 5833 topic_id: 8093 reply_id: 308093[/import]
