OpenGL help?

[taurine14]

Hello everyone!
I'm trying to code a 1980's Asteroids type game in OpenGL and I'm almost done, however one thing is really bugging me, and I can't seem to see what the problem is? I'm trying to draw 'stars' by drawing a hundred points at random coordinates using a drawStars function. Here is the code for the function:

  void drawStars(int numofstars)
{

	int yS = rand();
	int xS = rand();
	glColor3f(1.0, 1.0, 1.0);
	glBegin(GL_POINTS);
	glVertex2f( xS, yS);
	glEnd();
}

and when I call the function in the DISPLAY function, I just simply put:
drawStars(100);

Thanks guys!

You accidentally your loop. Notice how the variable you pass into your function isn't actually being used in that function? Seems kind of strange doesn't it?

Do this

void drawStars(int numofstars)
{
        for(int i = 0; i < numofstars; ++i){
	        int yS = rand();
	        int xS = rand();
	        glColor3f(1.0, 1.0, 1.0);
	        glBegin(GL_POINTS);
	        glVertex2f( xS, yS);
	        glEnd();
        }
}

Thanks for the help, the for loop worked fine. Going to kick myself now, so simple!
