Making a 2D game have perspective

Hello everyone. I'm looking for input.

I want to see if it's possible to create a game similar to this old game for Nokia phones:

youtube.com/watch

I want to have clouds, birds and other things in the level though. I've been thinking that I'd make every sprite have a variable that determines its position:

x = horizontal position, relative to the frame

y = vertical position, relative to the frame

z = altitude

I was thinking it might be possible to set all objects' position and size (the further away from the player's view, the smaller the object).

Even with no scrolling involved I would have to take distance into consideration. If an object is far away it won't move so much on the x and y axis, but if it's closer it has to move a lot.

I'm stumped so does anyone have any good tips in that might help?

this tutorial talks about pseudo 3D. which introduces the z-axis.

It might give you a few ideas.

I reckon you could do this by adjusting layer scale and parallax over time. Quick test: skydiver.capx

cvp - Thanks. I'll be sure to read it :)

ramones - Thanks to you to. Really nice you could just whip that up like that. I'll take a look at the code and see what's what.

ramones the little demo... it's awesome :D
