I'm currently working on a font-rendering system for my OpenGL based engine. I sure got something to work, but the only thing I still have problems with, is the horizontal advance!

example

This is what it spits out, obviously not correct. If I understood correct from the documentation and some other threads, this is the procedure to draw a string:

  1. set current drawing position to (0, 0)
  2. draw first character
  3. move drawing position in the x for advance.x
  4. draw second character
  5. move drawing position in the x for next face->glyph->advance.x
  6. ... repeat

Is that correct? If not, what am I doing wrong? I think its worth to say that I render every character as a texture!

As Bálint stated, the advance is for the next char. So just moving the cursor after drawing the current one solved it!
