i didnt know where else to ask, so i figured this was better than the rest of the forums. i have glutBitmapCharacter(GLUT_BITMAP_HELVETICA_18,first); glutBitmapCharacter(GLUT_BITMAP_HELVETICA_18,second); glutBitmapCharacter(GLUT_BITMAP_HELVETICA_18,third); where first, second, and third are all different int's. but they wont show up on my screen, and i moved the raster position. if i replace any with its number, like if first is 4, i do '4', itll show.

Try this:

glutBitmapCharacter(GLUT_BITMAP_HELVETICA_18,first + '0');

To understand why, look for information on ascii codes.

I initially made a mistake and wrote a - instead of a +.

Also, are you sure the values of the variables are 0 - 9? (i.e., they store a single digit)

ah, making it a plus, has made it work. but yes i made a little function to take a number and get the digits and display them.

TY!!!!
