narrator text position script by Spacepaw
modified by AFRLme
-- * --
script type: definition
-- * --
define absolute position of speaker text!
-- * usuage * --
in the editor set: game > speaker text alignment to "centered"!
then to display text: select action part > misc > display text > add text to display!
if you want to be able to walk about & do other things while narrator text is visible then ...
check the "show as background text" box!
only downfall to background text is you can't skip it!
