How to make background pictures
General idea is to produce map consist on rectangular tiles which looks-like 3d. Here is example of what we want to have:
OK, now look at this using grid:
We can see now how it can be divided into tiles. Tile here is sized 32x16 (some grid lines are splitting tiles into two rectangular ones).
I want to use much bigger tiles - I think 128x64 will be best, but this size is not fixed. For example by now it's sized 32x16. Each tile has it's own 4 borders - borders used are shown below.
D indicates dark rock, L light rock and S sand. Each borders are defined by two letters in correct order. (S,D is not equal to D,S).
Suppose backgrounds numbered 1 and 2 can be placed near. Below are listed all posibilities of tiles borders (if we've got only backgrounds 1 and 2). If we need more backgrounds (supprising, but natural) we need to have full tiles (with all borders B/B where B is background number) for all backgrounds and all border tiles for backgrounds which can be placed near (without separating borders).
Borders are listed as follows: up,left,down,right; Each numbers a/b means that a is more to left/higher than b.
- Full tiles - 1/1 1/1 1/1 1/1 and 2/2 2/2 2/2 2/2.
- Border tiles - 1/1 1/1 1/2 1/2, 1/1 1/2 2/1 1/1, 1/2 1/2 2/2 2/2, 2/1 2/2 2/2 1/2, 2/2 2/1 1/2 2/2, 2/2 2/2 2/1 2/1, 1/2 1/1 1/1 2/1 and 2/1 2/1 1/1 1/1.
- Special tiles - 2/1 2/1 1/2 1/2 and 1/2 1/2 2/1 2/1.
Picture below explains full 1 and 2 backgrounds for simple tileset (green and yellow).
