Hiding stuff while casting

[Dangergoppel]

I'm very new to LUA, so this is probably a noob question, but here goes anyway.

I'm creating my own oUF layout, and want to hide some of the units' health/mana/stuff-like-that text while the unit is casting. How in the world do I do this?

Thanks in advance for any help.

oUF's castbar-element provides the possibility to hook the 'casting', so you can execute a function, when a cast starts.

Use castbar:PostCastStart(unit, name, nil, castid) and castbar:PostChannelStart(unit, name) to hide certain elements.

However, you will have to restore, what you have hidden, so you will have to use castbar:PostChannelStop(unit, spellname) and castbar:PostCastStop(unit, spellname, nil, castid) aswell to show the elements again.

Have a look at oUF/elements/castbar.lua to get a deeper look.

Again, I'm very new, so I'm actually not very sure how to use those together with anything else. <_<'

k, let's go a little deeper then...

You got something like this:

-- self.Health.value = someSortOfFontString
-- self.Power.value = someSortOfFontString
 
-- self.Castbar = someSortOfFrameWithAllNecessaryCastbarStuff

What you have to add, is a function to hide self.Health.value and self.Power.value and another function to show them again:

local function myPostCastStart(self)
    self.Health.value:Hide()
    self.Power.value:Hide()
end
 
local function myPostCastStop(self)
    self.Health.value:Show()
    self.Power.value:Show()
end
 
-- now attach that functions to your castbar (inside of your styling function):
 
-- self.Castbar = someSortOfFrameWithAllNecessaryCastbarStuff
self.Castbar.PostCastStart = myPostCastStart
self.Castbar.PostChannelStart = myPostCastStart
self.Castbar.PostCastStop = myPostCastStop
self.Castbar.PostChannelStop = myPostCastStop

This is highly drycoded and my last attempt to help without seeing code... It's just guessing where your problem is. Bring up some code and we'll try to help.
