I'm trying to change the speech style from Lucas arts to SierrawithBackground but it will not change despite me changing it in the general game settings.
I tried using Speech.Style to change it manually but it said that the speech variable had already been defined despite me being unable to find where it was defined. I'm really stuck here so if anyone knows if this
is a glitch or I'm doing something wrong I'd really appreciate it.

I'm looking to make dialogue boxes for character speech like the game has for narration but I don't know where to start. I have read the manual and a few other tutorials on GUI but I'm kind of stuck here.
