Why doesnt this work??? bitmap fonts

Recommended Posts

I'm desperately trying to but a xy coordinate with a bitmapped font in the very sector i draw, but i get nothing at all.. i tested it out before outside of the loop, and it works, although i'm not sure what coordinate system i should use.
GLfloat angle,a,s,d;

GLvoid display(void)
{
	GLfloat x,y;
		
	/* Clear color and depth buffer [specified in init()] */
	glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
	
	/* Reset MODELVIEW and PROJECTION matrices */
	glMatrixMode(GL_MODELVIEW);
	glLoadIdentity();

	/* Initialization mode. Here we 	maintain our grid. */
	glTranslatef(0.0,0.0,-6.0);
	/* This will rotate local coordinate system!*/
	//for(a=0.0;a<95.0;a+=1.1) 
	glRotatef(a,1.0f,0.0f,0.0f);
	glRotatef(s,0.0f,1.0f,0.0f);
	glRotatef(d,0.0f,0.0f,1.0f);
	
	glMatrixMode(GL_PROJECTION);
	//glLoadIdentity();
	
	/* Setup our main grid. We use QUADS and POINTS to 
	define the sectors. The QUADS are using blending. */
	
	glBegin(GL_QUADS);
	
	for(x=-10.0;x<GRID_SIZE;x+=SECTOR_SIZE) {
	glColor4f(1.0,1.0,1.0,0.0);
	renderbitmapfont(x,y,0,GLUT_BITMAP_TIMES_ROMAN_10,"TEST");
	glColor4f(0.0,0.0,0.1,1.0);
		for(y=-10.0;y<GRID_SIZE;y+=SECTOR_SIZE) {
		glVertex3f(x-SECTOR_SIZE,y,0); 
		glVertex3f(x,y,0); 
		glVertex3f(x-SECTOR_SIZE,y-SECTOR_SIZE,0); 
		glVertex3f(x,y-SECTOR_SIZE,0); 
		glVertex3f(x-SECTOR_SIZE,y,0);
		glVertex3f(x-SECTOR_SIZE,y-SECTOR_SIZE,0);
		glVertex3f(x,y,0);
		glVertex3f(x,y-SECTOR_SIZE,0);
		}
		glColor4f(1.0,1.0,1.0,0.0);
		renderbitmapfont(x,y,0,GLUT_BITMAP_TIMES_ROMAN_10,"TEST");
	}
	glEnd();
	
	glColor4f(0.5,0.0,0.0,1.0);
	glBegin(GL_LINES);
	
	for(x=-10.0;x<GRID_SIZE;x+=SECTOR_SIZE) {
		for(y=-10.0;y<GRID_SIZE;y+=SECTOR_SIZE) {
		glVertex3f(x-SECTOR_SIZE,y,0); 
		glVertex3f(x,y,0); 
		glVertex3f(x-SECTOR_SIZE,y-SECTOR_SIZE,0); 
		glVertex3f(x,y-SECTOR_SIZE,0); 
		glVertex3f(x-SECTOR_SIZE,y,0);
		glVertex3f(x-SECTOR_SIZE,y-SECTOR_SIZE,0);
		glVertex3f(x,y,0);
		glVertex3f(x,y-SECTOR_SIZE,0);
		}
	}
	glEnd();
	
		
	glFlush();
	glutSwapBuffers();
	}
the bitmap function is :
void renderbitmapfont(GLint x,GLint y,GLint z,void *font,char *string)
{
	char *c;
	
	/* Set position of text */
	glRasterPos3f(x,y,z);
	
	for (c=string;*c!='\0';c++) {
    glutBitmapCharacter(font, *c);
  }
  
}
Please help because i'm going completely crazy.

for(x=-10.0;x<GRID_SIZE;x+=SECTOR_SIZE) {

for(y=-10.0;y<GRID_SIZE;y+=SECTOR_SIZE) {


You are using y outside of the the loop in which it is set. I'm not sure what you really intended, so I can't tell you exactly how to fix it, but you definitely don't want to be referencing y outside of the for-loop that sets it.
