Target Event/API

diospadre · 02/19/09, 12:27 PM

I use this bit of code (that I stole from nRune) to show/hide various frames when i enter/exit combat. I would like to modify it so that the frames show when I enter combat or have a target, but have not been able to find an event that will allow me to do this. Can anyone point me in the right direction?

    addon:SetScript("OnEvent", function()
        if (event == "PLAYER_ENTERING_WORLD" or event == "PLAYER_REGEN_ENABLED") then
            RuneFrame:SetAlpha(0)
	    MultiBarBottomLeft:Hide()
        elseif (event == "PLAYER_REGEN_DISABLED") then
            RuneFrame:SetAlpha(.7)
	    MultiBarBottomLeft:Show()
        end
    end)

I don't know if you have seen it, yet. But you should definitely take a look at this - Kong UI Hider. This might help, I hope.

That can hide/show based on combat, which I'm already able to do. I'm looking for a way to hide/show based on when I have a target.

I would think that adding a check for either "UnitExists("target")" or "UnitName("target") ~= nil" would do what you want. There's also a PLAYER_TARGET_CHANGED event, but it seems that you'd end up calling UnitExists or UnitName anyways.

Specifically, what you probably want to add is:

elseif (event == PLAYER_TARGET_CHANGED) then
    if (UnitExists("target"))
        RuneFrame:SetAlpha(.7)
	MultiBarBottomLeft:Show()
    else
        RuneFrame:SetAlpha(0)
	MultiBarBottomLeft:Hide()
    end

I can't guarantee it'll work.

Edit: That's probably missing a check whether you're in combat or not.

Time and Chicken: thanks for the help. You got me halfway there and now I have it working just as I wanted. Here's my final code.

    if (event == "PLAYER_TARGET_CHANGED") then
     if (not InCombatLockdown() and UnitExists("target")) then
        RuneFrame:SetAlpha(1) end
     if (not InCombatLockdown() and not UnitExists("target")) then      
	RuneFrame:SetAlpha(0.1)
	end
end
