well i have an issue with my inventory thing is i dunno
anything about setting global messages
i set my messages in my inventory or objects or whatever but i
get an error when i look at my inventory when im not in the room i found it in
You need to use global messages for inventory items, if you use the messages in the room it will only work if you look at the item in that room, hence the error in other rooms.
go to the Global Messages tab in the AGS editor and put the messages there (should be numbered from 500 onwards) then link the inventory item message number to the corresponding number eg. 500, 501 etc
That should do it
