(un)interruptable cast

[alimjocox]

i was wondering if oUF had a command / function or whatever its called ( not much a of a programmer ) which allowed us to change the color of the casticon/castbar border whether its interruptable or not, i.e. the shield u see in the default UI frames. thx in advance

Not directly. You can use a custom PostCastStart/PostChannelStart function to identify if the spell is interruptible and change the display of the castbar based on that. You should also track the UNIT_SPELLCAST_INTERRUPTABLE/UNIT_SPELLCAST_NOT_INTERRUPTABLE events in case the interrupt-ability of the spell changes during cast (e.g. during the Twin Valkyrs).

To add to this, here's how I'm doing it (in my non-updated version):

local postCastStart = function(self, event, unit, name, rank, text, castid, interrupt)
	if( interrupt ) then
		self.Castbar.bg:Hide()
		self.Castbar.Shield:Show()
	else
		self.Castbar.bg:Show()
		self.Castbar.Shield:Hide()
	end
end

local spellInterruptable = function(self, event, unitID)
	if( self.unit == unitID ) then
		if( event == 'UNIT_SPELLCAST_NOT_INTERRUPTABLE' ) then
			self.Castbar.bg:Hide()
			self.Castbar.Shield:Show()
		else
			self.Castbar.bg:Show()
			self.Castbar.Shield:Hide()
		end
	end
end

and in the layout function:

self:RegisterEvent('UNIT_SPELLCAST_NOT_INTERRUPTABLE', spellInterruptable)
self:RegisterEvent('UNIT_SPELLCAST_INTERRUPTABLE', spellInterruptable)

self.Castbar.Shield is not a standard item, you will need to define this texture yourself.

hey wurm thx for the reply i was just wondering if

local postCastStart = function(self, event, unit, name, rank, text, castid, interrupt)
if( interrupt ) then
self.Castbar.bg:Hide()
self.Castbar.Shield:Show()
else
self.Castbar.bg:Show()
self.Castbar.Shield:Hide()
end
end

is at all necessary?

[wurmfood]

The bg part isn't, really. However, you do need something to show or hide a texture that indicates if the spell can be interrupted or not. The event stuff only triggers if the spell becomes interruptible/not during the cast. Otherwise they don't trigger.

Is there a place/way to test such code? Without a raid/group, if possible.

[wurmfood]

The cast option changing? Not that I know of, and I've tried to find one.

Do you mean the events OR just interruptable and non-interruptable casts?

If the latter, you can just target yourself and use your mount or hearthstone.

You will need to add PostCastStart.

oUF already has castbar:PostCastInterruptible(unit) and castbar:PostCastNotInterruptible(unit).
