PROBLEM SOLVED. I had to make the array 22 x 22, and the for loops < 22. I realized the pack_fread function counts in the line changes as two chars. Anyway, thanks for the help guys.
Hi, I´ve been starring at this code the whole day, so I was hoping someone with fresh eyes could help me out why the tiles are not lining up properly on screen. I suspect it has something to do with the size of the maptab array or loadbuffer.
the tiles are 32 x 24 and the screen is 640 x 380 (20 x 20 = 400 tiles on screen).
| 1 | |
| 2 | |
| 3 | int maptab[20][20]; |
| 4 | |
| 5 | void mapload() |
| 6 | { |
| 7 | char loadbuffer[400]; |
| 8 | |
| 9 | PACKFILE *themap; |
| 10 | themap = pack_fopen("tiletest.txt", "r"); |
| 11 | pack_fread(loadbuffer, 400, themap); |
| 12 | pack_fclose(themap); |
| 13 | |
| 14 | int x; |
| 15 | int y; |
| 16 | int z = 0; |
| 17 | |
| 18 | for (y = 0; y < 20; y++) |
| 19 | for (x = 0; x < 20; x++) |
| 20 | { |
| 21 | maptab[ y ][ x ] = loadbuffer[z]; |
| 22 | z++; |
| 23 | } |
| 24 | } |
| 25 | |
| 26 | void tilemapping() |
| 27 | { |
| 28 | int x = 0; |
| 29 | int y = 0; |
| 30 | |
| 31 | for (y = 0; y < 20; y++) |
| 32 | for (x = 0; x < 20; x++) |
| 33 | if( maptab[ y ][ x ] == 1) blit(plat_cheq, buffer, 0, 0, x * 32, y * 24, 32, 24); |
| 34 | |
| 35 | } |
Here is the map file (20 x 20):
| 1 | |
| 2 | 11111111111111111111 |
| 3 | 00000000000000000000 |
| 4 | 00000000000000000000 |
| 5 | 00000000000000000000 |
| 6 | 00000000000000000000 |
| 7 | 00000000110000000000 |
| 8 | 00000000000000000000 |
| 9 | 00000000000110000000 |

What you mean exactly? Can you maybe provide a screenshot of what's going wrong?

]]>If you're waiting for diamond-shape style tilemap, you're not using the right formulae.
Other thing: your storing-loading routine is not common ... maybe you should re-thing to it
]]>I figured some things out, I changed
if( maptab[ y ][ x ] == 1)
to
if( maptab[ y ][ x ] == '1')
as I remembered a char is 8 numbers, and the maptab array to char allso.
but it still looks a bit twisted:

this works:

it looks like this (this is what it should look like)

but, I specifically would want to load my maps from files.
PROBLEM SOLVED. I had to make the array 22 x 22, and the for loops < 22. I realized the pack_fread function counts in the line changes as two chars. Anyway, thanks for the help guys.
