for(int i = 0 ; i < 3 ; i++) { vasp enemyvasp = {(rand()%10-10),(rand()%10-10), (float)(20-(rand()%30))/vaspSpeed, (float)(20-(rand()%30))/vaspSpeed} ; Enemy.push_back(enemyvasp); } The numbers 10-10 in the vasp enemyvasp = {(rand()%10-10),(rand()%10-10), Line should put the "vasps" that i will be drawn somewhere else in the program in some location at the "screen" tho when none of my drawings has any "zoom" the glTranslatef(xcoord,ycoord,zoom) so the screen aint really tremendous. Problem is the "vasps" (quads) will not show up on the "screen" any ideas on what numbers to use? or how to make the rand over to a float or double? vasp is a struct struct vasp { float x ; // vasp X position float y ; // vasp Y position float vaspmoveX ; // vasp X movement float vaspmoveY ; // vasp Y movement };

This..
(rand()%10-10)
is the same as doing
rand()%0
because the 10-10 is evaluated first.
Try ((rand()%10)-10).

Thanks Degra, tho i noticed the flaw in my code was not just those numbers, but made it work now thanks
