So, I know how to make a GUI pointer (GUI *myGui;), and I know that if I put that in the script header, the myGui pointer will be available in every room/script. BUT if I set myGui (myGui = gInventory;) in the global script, it's only usable in the global script - unless I also put a myGui = gXx in (for example) a room script, it crashes as a null pointer.
It's not, obviously, a major problem - I can just watch what/where I call - I was just wondering if there was a way to keep the settings across scripts.
You can export/import pointers just like variables:
// main global script
GUI *myGui; // define pointer for use in global script
export myGui; // export pointer for use in room scripts
then
// main script header
import GUI *myGui; // import pointer for use in all rooms
or
// room script
import GUI *myGui; // import pointer for use in this room
I hope I have understood you correctly.

If you define variables/pointers in the script header, a
seperate variable will be created for the global script and every room script. So if you change the pointer in the global script, it doesn't affect the pointer in the room script.

Yes, you have. I thought I'd tried every combination of import/exporting them - including that one - but I guess not, as it now works. Thank you, although I now feel like a total n00b.
