Hi, wizard of id.
I can help you with this.
Place a trigger zone on the map, and assign this textinzone.lua script to the trigger zone.
Type the text you want displayed on screen, into the Name field of the trigger zone in its properties window.
That's it.
So it shows whatever text, the trigger zone is named, when you walk into the trigger zone.
cheers.
I may be old, but at least my memory still ....hmmm
