Then my option, although lame, is still usefull.
I think i did not explained myself in the right way.
Lets say you create a text box in MAP001 with the following text:
Quote"Hello there, /n[2]"
35 maps later, you need that word to be changed with X. Then you use the Change Actor Name command in any event with the desired word.
The "/n[2]" in the text box placed in MAP001
will change accordingly since it is a dynamic variable.
We are asuming, of course, that he will use a custom message system that allows him to use the "/n[]" function to display the name of actor number 2.
