Sorry to bother again, but it appears I didnt get it right, because i cant get var_for_name to work.

Anyone there can help me by scripting an example, in the manual theres only 1 line of code:
var_for_name("camera.clip_far = 20000");

Actualy nevermind, my mistake:
This only works with global variables, I was using locals.
It appears this doesnt work with arrays too.
Thanks again.
