Hello,
I was developing my game and noticed that pointlessly repeating the same timer code over and over again is pointless when it wouldn't be hard to write a class that makes it easy. For that reason, I threw together a quick and dirty class in about 3 minutes that works well. You give it an interval and it executes your callback or returns a boolean wether the time has passed. You can find the code here.
I've included a few examples in the main code, but there are other things I didn't mention. For instance, you can change the interval on the fly by changing timername.interval = # of seconds
and change the callback by saying timername.callback = callback function
.
Let me know if you want more functions included like reset()
or something.
Thanks!

Don't know is you saw this, but I too was bothered by the lack of simple, generic
timer functionality. Here's mine that piggybacks off of tween:

@toadkick - I saw that while searching for a timer class. It's quite creative, especially that you don't have to call update, but it didn't have the control I wanted and relied on another Lua library.
Thanks!
Fair enough. Maybe I'm missing something, but did you post yours somewhere? I'd love to check it out.
I assume that by another library you mean tween.lua? I thought that was kind of fair game since Codea includes it now.
Anyway yeah, I was mostly just interested in seeing how tween might be used for a timer. I also thought it might appeal to the camp that doesn't like to put lots of update calls in their fraw function. It's not really ideal, but it's better than the ol' "put a counter on the draw function" chestnut.
@toadkick - Sorry about that. The "here" in the sentence "You can find the code here." has the link in it. I'll make it bold.
Edit: And for the heck of it, italics and red.
Hi . In my windows library you will also find a WindowsTmers() class. It is standalone, can manage any number of timers, and is Speed optimized.
A much better attempt, that doesn't use tween:

EDIT: revised:
@toadkick - Nice... That's worth putting on the wiki.
@Jmv38 - I hadn't seen that windows library, but it look sweet. Nice job!
