Issues creating an install window

[WhiteWolf87]

I am trying to create an install window for my addon compilation. The install window works fine, but after the reload, there should be an art frame at the bottom of the screen.

Note: This installer is not quite finish by any means, I am working on one bit of it at a time.

You don't have access to any file system functions in WoW's Lua. The only way to load code on demand is to use load on demand addons.

You should probably take a look at the Things Addons/Macros Can't Do sticky thread. Addons cannot access anything -- files, system functions, network connections, etc. -- outside of the in-game UI sandbox.

Yea, I've read this. I was merely trying to run code that is within the same folder. When I tried to do it as a function it merely it didn't stick when i reloaded the UI.

Ah, you are misinterpreting the WoW interpreter; most of the Lua syntax simply does not exist, and thus cannot execute.

In Warcraft, there are no APIs to access the hard drive, for example, and so calling said APIs results in nil value errors.

When Phanx linked the cannot do list, it is exactly as she says: you cannot do these things. At all. Ever. Zero possible ways to accomplish them.

Blizzard removed all such APIs from their Lua environment.

Hopefully that is more clear.

Yes, I understand now. Thanks.

Re-uploaded the addon and changed first post to reflect my issue.

As a follow up, since I didn't look at your code, it is possible to have an install screen for AddOns. Several full UI suites use them, and there may be other types.

It is all about how you code. You could take a look at ElvUI/TukUI.

I got the installer to work, but after it reloads the UI it doesn't show the art frame at the bottom.

For a more straightforward example that also doesn't require wading through a poorly designed third-party site to find a download, look at the first-time setup dialogs in Mayron UI.

You need to use saved variables to keep track of whether the user has already installed your UI, and if there are options (eg. which art frame to show) to keep track of those as well. When your addon loads, check your saved variables to see whether you should show the install dialog or create the art frame, and then do that.

-- LCIres["Res1"] always be false when you reload ui for those code:
if type(LCIres) ~= "table" then
    LCIres = {}
    LCIres["Res1"] = false
else
    if LCIres["Res1"] == true then
           -- skip
        end
end

When you reload the ui, the LCIres won't be existed in the _G, so you need put the LCIres in saved variables and check it when your add-on is loaded.

Ah, can't believe I missed that! Thank you so much got it to work now :P
