strange tiles...

[theHAWKER]

i am having some truble under standing thies tiles...

in the script "dirt path" found in levels/npcs it uses numbers and letters (0xaa)

how do thise number-letter-combonations corospond to the tile set, so i can make bush generators, or things like tree genorators

Edit: here is a bigger example:

PHP Code:

function laypath() {
  sandtiles = {0xaa,0xab,0x12d,0x8,0xf};
  grasstiles = {0x0,0x1,0x10,0x1ff,0x3ff,0x7ff,0x835,0x836,0x837};
  sandspot = {
    0x176,0x166,0x177,
    0x1a7, 0xaa,0x197,
    0x188,0x178,0x169
    };
