void setupdebris()
{
int n,x,y,size,color;
//fill the battlefield with random debris
for (n = 0; n < BLOCKS; n++)
{
x = BLOCKSIZE + rand() % (SCREEN_W-BLOCKSIZE*2);
y = BLOCKSIZE + rand() % (SCREEN_H-BLOCKSIZE*2);
size = (10 + rand() % BLOCKSIZE)/2;
color = makecol(rand()%255, rand()%255, rand()%255);
rectfill(screen, x-size, y-size, x+size, y+size, color);
}
}
How should I do this?

In the following code, which I took from the book Game programming all in one, 2nd ed." blocks are randomly generated on terrain. I want to make it so they arent randomly generated, And I can just specify there exact location. heres the code
I am sure theres probably a simple way to do this, but I cant seem to see it.
You just need to read in the data from a file or from a hard-coded array instead of using rand().
with blocks.dat containing rows of
x y size color_r color_g color_b
void setupdebris(){ int n,x,y,size,r,g,b,color; FILE *file = fopen("blocks.dat"); //fill the battlefield with random debris while (6 == fscanf(file, "%d %d %d %d %d %d", &x, &y, &size, &r, &g, &b)) { if (x < BLOCKSIZE) x = BLOCKSIZE; if (x > SCREEN_W-BLOCKSIZE) x = SCREEN_W-BLOCKSIZE; if (y < BLOCKSIZE) y = BLOCKSIZE; if (y > SCREEN_H-BLOCKSIZE) y = SCREEN_H-BLOCKSIZE; if (size < 10) size = 10; if (size > BLOCKSIZE+10) size = BLOCKSIZE+10; size /= 2; color = makecol(rand()%255, rand()%255, rand()%255); rectfill(screen, x-size, y-size, x+size, y+size, color); } fclose(file);}with blocks.dat containing rows of
x y size color_r color_g color_b

ok, thanks! so I essentialy just create a file with numbers numbers in a certain order to get the level I choose?
Yep.
The next bit, that makes it all worth while, is that you can now have multiple level files - your task now is to write a level editor! :) Of course, for a simple format like this you can probably get away with just editing files by hand.
