I'm not having much luck making buttons work with Lua.
I change the language to Lua, but that only seems to affect the script that runs when I click the button.
I'd like to set the caption with a Lua expression. Same thing with the various expressions expected in gauges--using Lua expressions just doesn't work.

Am I not seeing something, or is it even possible at the moment?

The language selection applies only to the button's script at the moment, not any of its captions. It's perhaps something that could be looked at in the future, but it has a number of associated problems, chief of which is that CMUD monitors its own variables when they're used in captions or gauges so that the GUI can be updated when they change - it doesn't do this kind of monitoring with Lua variables.

There're two possible workarounds - either your expression is simple, in which case using zScript for the caption would probably be better in the first place, or it's complex and needs to use Lua, in which case you're probably best to have your script update a zScript variable every time the expression in question changes, and then use that variable in the caption.

That makes sense about CMUD monitoring and updating the captions/gauges as variables change.

And to be honest, I was just trying to keep my classes free of clutter. I don't really care to see all those simple numeric variables my prompt creates... I'd rather have them in a Lua "stats" table.

I think it'd make a great addition. Thanks for the workarounds.

There are other ways to keep your classes free from clutter. For instance, perhaps a database variable would work to hold the values from your prompt?

Database variable? I play a pretty involved combat mud. I'm not one to prematurely optimize, but that really seems like a recipe for slow-down. It's a good idea, but I think I'd rather just clutter up a "Gauge" class with some variables I won't use elsewhere.

Ah. Yes, I forgot you were talking about gauges. Values within a database variable won't work for a gauge.
