Thread: OpenGL Labeling problem

hi there!

in my little game I have some Objects obviously.
they all look very similar so I want to implement a method to label them with their name. so i did this:

Code:

void MyObject::printName()
{
    const char *string = "test";

    glPushMatrix();

    glLoadIdentity();
    double i;
    glLineWidth(0.1);
    glBegin(GL_LINE_STRIP);
    for(i=0;i<2*PI;i+=PI/16)
     	glVertex3d(*fXPos+(radius+0.1)*sin(i),*fYPos+(radius+0.1)*-cos(i),0.0);
   	glVertex3d(*fXPos+(radius+0.1)*sin(0),*fYPos+(radius+0.1)*-cos(0),0.0);
    glEnd();
    glBegin(GL_LINE_STRIP);
   	glVertex3d(*fXPos+(radius+0.1)*sin(12*PI/16),*fYPos+(radius+0.1)*-cos(12*PI/16),0.0);
   	glVertex3d(*fXPos+(radius+0.2),*fYPos+(radius+0.2),0.0);
    glEnd();
    glRasterPos3f(*fXPos+radius+0.2,*fYPos+radius+0.2,0.0);

    glColor3f(1.0,1.0,1.0);
    while(*string) glutBitmapCharacter(GLUT_BITMAP_HELVETICA_10, *string++);
    glPopMatrix();
}

this worked pretty well until I added a lightsource.
now the letters have the same color and shading of the object they are attached to. how can i prevent that???

thx+regards

are the objects textured? if so try disabling textures before drawing your text.

no I did not use any textures yet but disabling the lighning was a great help!
would not have thought of it of my own, thnks a lot!
