Sounds like you're in over your head.

Do you know how to program?
Do you know how to program games for a PC?
Do you know how to program for the PSP?

I would solve these problems in that order.

Excellent, sounds like you're experienced enough. Sorry, there are so many newbie posts nowadays... I did not mean to offend.

I would go for a top-down approach, then you should find that what you need to do becomes apparent as you need it.

Start off with the high level logic flow - initialisation, title screen, game "play" screen, game over, etc. Some design patterns like "Run and return successor" can help with this.

Then you'll probably find that you need to set up a world for playing in, with a tile-based map, and sprites for characters. How you store and process this lot depends on your preferences.

Hope this helps,
Pete

i think my problems will be only world scrolling and collisions betweeb character and world..

anyway..tnx! :)

Scrolling's not so bad, you just offset your blits by the camera position.

Collision can be a paint though, especially if you support slopes.

If you want to take a look, I started a side-scrolling engine game months ago. It is written in Lua but should give you an idea of how the block collision works.

doesnt the oldschool library give you the ability for easy scrolling / sprites / tiles etc ?
