Event lag issue

[Sheae]

Hey guys!

I'm somewhat new to addon creation, and I've encountered a little problem. I've reinstalled my windows and currently using default UI, but I've made myself a small unitframe, as the default playerframe is way to far from the actionbars, and as a fury warrior, I have to see my current rage almost every second.

The problem with it, is that I used OnEvent script with UNIT_POWER, and its kinda laggy.
The default playerframe shows my rage decrease as: 7 6 5 4 3 2 1 0.
With the OnEvent script my frame shows it as: ..(zZz)..7..(zZz)..5..(zZz)..3..(zZz)..1
In some cases it even stucks on 1 (when I have 0), until my rage changes again.

I was sure it's not about one more statusbar shown on screen, as it doesn't use as much resource to make it laggy. However, I tried this: I removed everything from the lua (well only made it a comment --[[ ), and what was remeaning is a frame, the OnEvent script, and the handler for it. The handler function printed my current rage to the chatframe, nothin else, and the result was the same: 7..5..3..1..

I've solved the problem by switching to OnUpdate on the frame, but I think it will use too much resource when I will make the whole raidframes with power and health bars.

The questions I'd like to be answered are: what causes the events to be laggy? How can it be solved?
If I use OnUpdate, will it use much more CPU when there will be raidframes using OnUpdate too (instead of OnEvent)?

I don't think there is a way for those events to work differently (i.e. they are always going to be haphazard).

Have you taken a look at how the standard bliz frames that show health/mana are implemented?

Provided you avoid putting in too much activity in your onupdate it isn't actually too problematic (there is also the option of setting up a make shift timer, so that it only updates information perhaps every 200ms for example)

It is not possible.

The default playerframe use the onupdate script for the power bar.

There is no "bug" with it, UNIT_POWER only show ticks, not a static value.
If you want that you'd need to use an OnUpdate script.
