Need help from Fox or any1 who knows tile engines...

[squirrelly1]

Fox or whoever,

I saw a thread about how a person setup a tile map using DirectDraw adn the map looked something like this...

1203104
2012310
3122310
3122310

Where 0 would be grass, 1 whatever, 2 whatever, and so on...

Do you know what I mean??? I hope so...

My question is... What is the principle behind this? It seems like a pretty simple way of doing things, if I could only grasp the concept.

I'm pretty new to direct draw, so you might want to be a little explanitory in your reply...

Thanx in Advance,

You would replace each instance of 0 with a grass tile, say you had an array of these:

Dim Map(5,5) As Integer
Dim I, J
For I = 0 to 4
For J = 0 to 4
Select Case Map(J,I)
Case 0
   DrawTile ddPath, J * TILE_WIDTH, I * TILE_HEIGHT
Case 1
   DrawTile ddMountain, J * TILE_WIDTH, I * TILE_HEIGHT
Case 2
   DrawTile ddForest, J * TILE_WIDTH, I * TILE_HEIGHT
Case 3
   DrawTile ddPlains, J * TILE_WIDTH, I * TILE_HEIGHT
Case 4
   DrawTile ddLava, J * TILE_WIDTH, I * TILE_HEIGHT
Case 5
   DrawTile ddGrass, J * TILE_WIDTH, I * TILE_HEIGHT
Case 6
   DrawTile ddWater, J * TILE_WIDTH, I * TILE_HEIGHT
Case 7
   DrawTile ddDirt, J * TILE_WIDTH, I * TILE_HEIGHT
End Select
Next J
Next I

This is of course a bad way of doing things, you may have DrawTile Tiles(Map(J,I)), J * TILE_WIDTH, I * TILE_HEIGHT, which would be a lot better and easier. DrawTile would be a hand-made function, a wrapper for DirectDraw when drawing a tile. TILE_WIDTH and _HEIGHT would be how big your tiles were (16x16, 32x32, etc.)

Sastraxi,

Thanx for the help, and exspecially the code! I understood that I would have to replace the numbers with a picture of some sort (tile), but wasn't sure how...

Thanx,

P.S. If I run into any more problems, I'll be sure to post them for you VB Wizards out there!
