Hookscript

Hi,

quick 2 questions:

1. how can you remove hookscript from frame upon some condition?
2. what is the best way to wait for some frame to show in UI... and i dont mean to Show() when already exists.. i mean to get it when it is created regardless of its visibility state?

i want this:

Code:

UIParent:HookScript(

        "OnUpdate",

        function(self)



                if CUSTOMFRAME then

                        CUSTOMFRAME:HookScript(

                                "OnUpdate",

                                function(self)

                                        print("have it")

                                end

                        )

                        



                      UNHOOK UIPARENT BECAUSE I FOUND FRAME

                end

        end

)

Thank you.

You can't unkook something, just alter what the hook function does,

You could use OnUpdate on a frame of your own and when the CUSTOMFRAME is found, hide your frame (that stops it's OnUpdate from running) or set it's OnUpdate script to nil.

Maybe something like:

Lua Code:

local T = C_Timer.NewTicker(1, function()
    if CUSTOMFRAME then
        CUSTOMFRAME:HookScript("OnUpdate", function(self)
            print("have it")
        end)
        T:Cancel()
    end
end)

There are probably other possabilities depending on what other conditions might exist

Is the frame in a Load-On-Demand addon?
Is there another frame/function that creates the frame that you can hook?
...???

That code return error... saying T is not found... i just put self:Cancel() instead...

In any case thank you.. i managed to get it working.

From https://github.com/tomrus88/Blizzard...merAugment.lua I'd guess the callback gets called with the right object to use cancel on. So this should work:

Lua Code:

local T = C_Timer.NewTicker(1, function(self)
        if CUSTOMFRAME then
            CUSTOMFRAME:HookScript("OnUpdate", function(self)
                print("have it")
            end)
            self:Cancel()
        end
    end)

Indeed, I left the T out of the function declaration... oops

Lua Code:

local T = C_Timer.NewTicker(1, function(T)
