I'm trying to have a variable that decrements by one when a player clicks on certain objects. However, the triggers weren't working so I put a print statement in the Lua code, and apparently it's being read as 'nil' even though I put an initial value in the Dialogue System. Any help would be appreciated!

Hi Alex,

Use:

Code: Select all

print(Variable["Valves_Turned"])

Thank you! I'm still new to Lua, sorry.

No problem! Your original code was perfectly valid Lua. It's just that the Dialogue System stores all of its dialogue database variables in a Lua array named Variable[]. So to access a dialogue database variable, you need to specify the Variable[] array.

That makes sense. I'll have to remember that for the future.
