2D Scrolling

Hi all,
Just wondering how people go about doing a 2D scrolling game.
I am doing a game when the level will be populated using a tile map and I want to be able to scroll the map in 8 directions at any speed with accurate collisions.
Would I be better storing my tile info in an array or in a type, to allow more flexability.
I am using BlitzMax.

Any links to tutorials or tips welcome.

Cheers
DIJ

Take a look at this : http://www.scottshaver2000.com/forum/viewtopic.php?t=94

I'd make a 2d array of ints/shorts/bytes if your mapdata only has a simple structure and a custom tiletype if your mapdata is a little bit more complex (gfx numbers, event triggers, discovery fog etc.).

Then it's all a matter of displaying parts of the map in the right part of the screen. Just work with pixel-based coordinates. If your tiles are like 16x16 and your pixelcoordinate/mapoffset is like 66,40 then the tile offset would be 4,2 (int 66/16, int 40/16) and the pixel/scroll offset would be 2,8 (66 mod 16, 40 mod 16). So, you'll know what tiles to draw and at which offset.. piece o' cake!

There is also my tilemap example available from the code section of my Blitz site below (the right one of those two logos). Just scroll down a bit and you'll find one for BlitzMax.

The link doesn't work.

Thanks for the help and links, I should be able to figure it out from there.

@JazzieB, I'll have a look at the example. Ta

I would probably use an array of types
