Now I've built games in xna so I think I'll be ok with the framework mono touch, but I've only ever worked on really simple games in xna so I need to ask a few questions that will help me get started:
If I want to build a world thats bigger than my screen and when the character moves, keep him in the center of the screen but have him move towards the destination that was touched (move the world not the character ?!). Then when world space runs out allow the character to move from the centre on that axis - how would this be implemented? Is there an algorithm or does this have a name so I can look into it?
I want to get started on a simple a* path finding solution, does anyone have any ideas how this would be tied into the question above.
