Can't get custom threat element working

[Kayja]

Trying to write myself a very simple agro bar element, does nothing fancy as it's only for me, but I just cannot get it to show the bar. I originally tried using the Hide / Show features which obviously won't work because if I hide it then it kills the updating of it, so I'm trying with SetAlpha instead.

The update should just simply checking if I have a target and that it's not friendly before it'll do anything with the bar.

Thanks in advance if you can provide any assistance. Wasn't sure whether to post this in the LUA/XML Help area or in here, but since it's oUF specific I thought it'd be best here.

[Edit]: Nevermind, all sorted wrote it kinda wrong.

Check out rThreat. Maybe you can find some inspiration there. There are also some oUF threat plugins already.

Thanks zork, I will do just that

The problem was that Update from the AddElement didn't seem to fire more than once, I just couldn't get it to keep updating so it just did the update once and that was it, so when I entered combat the bar didn't appear. I had to add an OnUpdate script to the "Update" function for the element to get it to work, not sure if this is the best way to do that. I've wrote in my todo list that I want to rewrite it again as I'm not happy with it, when I do that I'll use your rThreat for ideas.

I just skimmed your post before leaving work, and you had edited away the code when I got home, but if I remember correctly:

You didn't register any events, so of course the element wouldn't be called more than a few times through OnShow and PEW.

Ahh, that's makes sense and yes you're right I never registered events and even on my rewritten version I'm not using any and are just pulling threat from UnitDetailedThreatSituation with a low delay OnUpdate which I never liked but it was the only way I got it working. Can't believe I forgot the events! *facepalm*

Thanks for your help, will rewrite it later with threat events.
