breakout game scoring

[pbivens]

I am trying to draw numbers to the screen, I want to erase the 1 in 100 to 2 in 200 for game scoring. Here is the code I am working on.

void drawBitmapText(char *string,float x,float y,float z) 
{  
char *c;
glRasterPos3f(x, y,z);
for (c=string; *c != '\0'; c++) 
{
glutBitmapCharacter(GLUT_BITMAP_TIMES_ROMAN_24, *c);
}
}
 
void brick_collision()
{
	if(bricks[2][4]==true)
	{
	drawBitmapText("100",4.0f,2.0f,0.0f);	
	}
 
	if(bricks[2][3]==true)
	{
	drawBitmapText("200",4.0f,2.0f,0.0f);	
	}

I am still stuck on how to print a blank character to the screen using glutBitmapCharacter command.

well I have almost solved my problem here is the code I am using.

	if(bricks[1][4]==true)
	{
	n+=200;
	str=itoa(n,buffer,10);
	glRasterPos3f(4.0f,2.0f,0.0f);
	glutBitmapCharacter(GLUT_BITMAP_TIMES_ROMAN_24, 32);
	drawBitmapText(str,4.0f,2.0f,0.0f);	
	}
 
	if(bricks[1][3]==true)
	{
	n+=200;
	str=itoa(n,buffer,10);
	glRasterPos3f(4.0f,2.0f,0.0f);
	glutBitmapCharacter(GLUT_BITMAP_TIMES_ROMAN_24, 32);
	drawBitmapText(str,4.0f,2.0f,0.0f);	
	}
 
	if(bricks[1][2]==true)
	{
	n+=200;
	str=itoa(n,buffer,10);
	glRasterPos3f(4.0f,2.0f,0.0f);
	glutBitmapCharacter(GLUT_BITMAP_TIMES_ROMAN_24, 32);
	drawBitmapText(str,4.0f,2.0f,0.0f);	
	}
 
	if(bricks[1][1]==true)
	{
	n+=200;
	str=itoa(n,buffer,10);
	glRasterPos3f(4.0f,2.0f,0.0f);
	glutBitmapCharacter(GLUT_BITMAP_TIMES_ROMAN_24, 32);
	drawBitmapText(str,4.0f,2.0f,0.0f);	
	}
 
	if(bricks[1][0]==true)
	{
	n+=200;
	str=itoa(n,buffer,10);
	glRasterPos3f(4.0f,2.0f,0.0f);
	glutBitmapCharacter(GLUT_BITMAP_TIMES_ROMAN_24, 32);
	drawBitmapText(str,4.0f,2.0f,0.0f);	
	}

I am so close I need only a little bit of help.

I want to erase the 1 in 100 to 2 in 200 for game scoring.

You don't normally erase anything - since you are redrawing the frame each time click; when you draw the text they is only the new image underneath.

Likewise a space can be "drawn" by just incrementing your x position by how ever many pixels you want a space to be.

so is there anyway to draw a blank character over a regular character.
