Is there a way to pause Codea while an alert is showing, or set a callback for when the OK button is pressed?
not that i know…
Check out my alert Objective C add on… You can also modify it by saying codeaViewController.runtime.paused = TRUE (something like that) untill the callback. So, yes, you can get callbacks.
Thanks.
You could create your own alert library in codea that could include this function
@Jmv38 - I think you have your terminology mixed up (or your implications). “Native code” typically implies that you’re referring to Objective C or C. However, I think you mean “native to Lua/Codea.” Also, a “compiled app” is your app after you click the run button in Xcode. The easiest way to explain compiling something is basically when the Objectice C/C/C++ code is converted in assembly, making it (virtually) unreadable.
But to answer your question, yes, my library only works once your app has been exported.
@Coder - That’s what my library does. It allows you to have multiple buttons, set the cancel button name, and have callbacks. Mine pretty much covers the basics of the common alert view.
You could overload alert() and have it copy draw and replace it with a blank one. When alert is clicked make draw == old draw.
@Briarfox, true - good idea.
That said, callbacks can be used for multiple things, so @Simeon it might be a nice feature to add.
@JakAttak - What’s wrong with my solution?
@Briarfox - I’m not sure what you mean. You can’t overload functions in Lua (well, without writing a lot of extra code). Did you mean override?
o_alert = alert
alert = function(params)
--hook draw here
--call original alert
o_alert(params) end
Yeah meant override, typing on my iphone while at dinner 
@Zoyt, I was looking for something that works in Codea, and your solution requires moving to the runtime. That said, that add-on does look nice. I think we should have an alert function like yours built in to Codea.
Didn’t want to start another thread for this, so I thought I’d add to this one:
io.popen doesn’t seem to work. It shows as a function in the editor, but when i try to use it for anything it returns error of 'popen' not supported
What does io.popen have to do with alert callbacks?
Nothing, I just didn’t want to start a new thread. Call this ‘JakAttak’s Miscellaneous Queries’
@JakAttak - File a bug report. Simeon reads those more than he reads the forums, as far as I can tell.
So it is a bug?
