There is no defense 
HI. I have made a simulation of the game of life in C, but I wanted to make it in Allegro language.
The question is the following: my original program makes a board of 300*150 of aleatory 0 and 1, and then everytime i press enter the board transforms into another one of 0 and 1, according to preset rules.
How can i make, for example, that each 1 appears as a white square and every 0 as a black square? I know it is probably very basic by i've read many tutorials and i haven't seen it explained anywhere.
If seeing the program in C would help answer the question i can post it, its not very big.
Thank you.
I'll post what I can, based on the info you posted (just the drawing bit, tough it's not tested and can be buggy like hell):
| 1 | #include "allegro.h" |
| 2 | |
| 3 | #define MAPW 300 |
| 4 | #define MAPH 150 |
| 5 | #define RECTSIZE 16 |
| 6 | |
| 7 | int map[MAPW][MAPH]; |
| 8 | |
| 9 | BITMAP *buffer; |
| 10 | |
| 11 | int main() |
| 12 | { |
| 13 | //init |
| 14 | //populate the map array |
| 15 | |
| 16 | buffer = create_bitmap(SCREEN_W, SCREEN_H); |
| 17 | |
| 18 | while (!key[KEY_ESC) |
| 19 | { |
| 20 | clear(buffer); |
| 21 | |
| 22 | for (int y=0; y<MAPH; y++) |
| 23 | { |
| 24 | for (int x=0; x<MAPW; x++) |
| 25 | { |
| 26 | //I'm assuming you have a non-black background |
| 27 | if (map[x][y]==0) |
| 28 | { rectfill(buffer, x*RECTSIZE, y*RECTSIZE, (x+1)*RECTSIZE, (y+1)*RECTSIZE, makecol(0, 0, 0)); } |
| 29 | else if (map[x][y]==1) |
| 30 | { rectfill(buffer, x*RECTSIZE, y*RECTSIZE, (x+1)*RECTSIZE, (y+1)*RECTSIZE, makecol(255, 255, 255)); } |
| 31 | } |
| 32 | } |
| 33 | |
| 34 | blit(buffer, screen, 0, 0, 0, 0, SCREEN_W, SCREEN_H); |
| 35 | } |
| 36 | destroy_bitmap(buffer); buffer = 0; |
| 37 | //exit |
| 38 | } |
| 39 | END_OF_MAIN() |

Well, the program wasn't very buggy, but i tried to run it two times and both of them the windows said there was an error and the window had to close. Anyway thanks for your post.
I'll just post now the program i have made and if someone has got the pacience, i would appreciate if he/she could give a little help, cause i have to make this as a college project: (just the main)
int main()
{
int i, j, h;
char x;
board_init();
for(h=1; h <= MAX_GEN; h++) {
board_out(h);
for (i=0; i<=N; i++) {
for (j=0; j<=M; j++) {
stone(i, j);
}
}
c = getchar();
}
return 0;
}
Yes, well... I did put //init and such in the code since I thought you knew how to init all the allegro stuff.
allegro_init(); set_color_depth(desktop_color_depth()); set_gfx_mode(GFX_AUTODETECT_WINDOWED, 800, 600, 0, 0); install_keyboard();

Since when allegro is a language ? I always thought it was a library :p

Héhé. We made the thread going mad.
So, do the OP is happy with the stuff and knowledge CursedTyrant gaves to him ?

I think The Game of Life has been run on a GPU as well.

No. Writing "tough = thought" means assigning thought to tough. After that one can write tough.

Good, that's what I tough.

| 1 | //8 bit version |
| 2 | |
| 3 | #include <allegro.h> |
| 4 | |
| 5 | RGB white = { 63, 63, 63, 0 }; |
| 6 | RGB black; |
| 7 | |
| 8 | int color; |
| 9 | |
| 10 | int main(void) |
| 11 | { |
| 12 | allegro_init(); |
| 13 | install_keyboard(); |
| 14 | if(set_gfx_mode(GFX_AUTODETECT_WINDOWED,640,480,0,0)) |
| 15 | { |
| 16 | set_gfx_mode(GFX_TEXT,0,0,0,0); |
| 17 | allegro_message("Bad graphic mode"); |
| 18 | return -1; |
| 19 | } |
| 20 | |
| 21 | set_color(0,&black); |
| 22 | set_color(1,&white); |
| 23 | //loop would start here |
| 24 | color = some_arcane_calculation; |
| 25 | circlefill(screen,10,10,20,color); |
| 26 | readkey(); |
| 27 | return 0; |
| 28 | } |
| 29 | END_OF_MAIN() |
| 30 | |
| 31 | |
| 32 | //Truecolor version |
| 33 | #include <allegro.h> |
| 34 | |
| 35 | int colorvals[2]; |
| 36 | |
| 37 | int color; |
| 38 | |
| 39 | int main(void) |
| 40 | { |
| 41 | allegro_init(); |
| 42 | install_keyboard(); |
| 43 | set_color_depth(24); |
| 44 | |
| 45 | if(set_gfx_mode(GFX_AUTODETECT_WINDOWED,640,480,0,0)) |
| 46 | { |
| 47 | set_gfx_mode(GFX_TEXT,0,0,0,0); |
| 48 | allegro_message("Bad graphic mode"); |
| 49 | return -1; |
| 50 | } |
| 51 | |
| 52 | colorvals[0] = 0; |
| 53 | colorvals[1] = makecol(255,255,255); |
| 54 | //loop would start here |
| 55 | color = some_arcane_calculation(); |
| 56 | circlefill(screen,10,10,20,colorvals[color]); |
| 57 | readkey(); |
| 58 | return 0; |
| 59 | } |
| 60 | END_OF_MAIN() |
[EDIT] I did have "putpixel()" where circlefill is but they were too small to see when quick testing that it'd actually work.
