[0.3.2] Lua/GuiElement and isvalid

Post by rk84 »

I try to check validness of button that is in flow. But I get "LuaGuiElement::LuaIndex: unknown key nameofbutton"
I guess I will have to save the state of button.

btw could you make method to change caption? Deleting and recreating buttons change the order of buttons

edit: I keep getting this "LuaGuiElement::LuaIndex: unknown key nameofbutton" with destroy() too. Eventhough I see the button on screen. I dunno, might be my code.

edit2: Here is the code that I'm having problems with. It supposed to be creative mode. Works nice except after couple clicks it kind of looses reference to buttons it supposed to destroy.

Code: Select all

require "defines"

itemlist = {}

Re: [0.3.2] Lua/GuiElement and isvalid

Post by kovarex »

In the 0.4, the default behaviour will be getting nil, when you request element that is not present, so will be ok to test if the element is there.
Unless you name your element name or caption :)
It will be possible to change the caption (and bold/color as it will be added) as well.
