KgPanel issue with hiding a panel.

[Deleted]

Hey, I have this button my on UI which changes its alpha to 1 if you hold the Alt key (while out of combat) and its onClick script only works if you hold the alt key down as well. My problem however is that the panel blocks the Target of Target Frame and when you are not holding alt down it blocks interaction with mouse clicks as the frame is not disabled/hidden, its just invisible.



If I change SetAlpha(1) and SetAlpha(0) to Hide() and Show() then holding the Alt key no longer shows it so I can't use that.

This is the image of what I mean and below is my onUpdate Script:

if kgPanels:FetchFrame("BottomBars"):IsVisible() then      
self:Show()
else
self:Hide()
end  

if IsAltKeyDown() and not IsControlKeyDown() and not IsShiftKeyDown() then
self:SetAlpha(1)
else
self:SetAlpha(0)
end

If anyone knows anything that could help me out then I would appreciate the help Thank you for reading!

Don't use OnUpdate, that's redundant. Register for MODIFIER_STATE_CHANGED, PLAYER_REGEN_ENABLED and PLAYER_REGEN_DISABLED. Something like this should work:

OnLoad

self:RegisterEvent("MODIFIER_STATE_CHANGED")
self:RegisterEvent("PLAYER_REGEN_ENABLED")
self:RegisterEvent("PLAYER_REGEN_DISABLED")
function self:UpdateVisibility()
    if IsAltKeyDown() and (not IsControlKeyDown()) and (not IsShiftKeyDown()) and (not self.combatState) then
        self:Show()
    else
        self:Hide()
    end
end

OnEvent

if event == "PLAYER_REGEN_ENABLED" then
    self.combatState = false
elseif event == "PLAYER_REGEN_DISABLED" then
    self.combatState = true
end
self:UpdateVisibility()

Note: I'm not sure how to get the event name in kgPanels. I'm assuming the loadstring is either wrapped into a function(event) or setfenv()'d to have 'event'. If it's not named 'event', check how it is named, then update accordingly.

Thank you. You taught me a lot with that and I won't use OnUpdate again
That works perfectly!

I am having a few issues with this. The first is that when I log on I get a lua error which I've linked at the bottom of this post. Another is that when I log on, the panel is showing when I am not holding down the Alt key which is most likely because of the lua error. The other problem is that I had to reuse the OnUpdate code which you said was redundant because I have two panels and the both should only show with the Alt key if their own targeted panel is showing: "if kgPanels:FetchFrame("BottomBars2"):IsVisible() then...". It is hard to explain without using my UI but I hope this makes sense. Sorry for the overwhelming amount of code that follows this. It is just the best way to explain my problem. My lua skills are poor so I'm sure there is a lot wrong with what I'm doing. Thank you for your time if anyone looks through this.


First Panel:
OnLoad:

self:RegisterEvent("MODIFIER_STATE_CHANGED")
self:RegisterEvent("PLAYER_REGEN_ENABLED")
self:RegisterEvent("PLAYER_REGEN_DISABLED")

if kgPanels:FetchFrame("BottomBars"):IsVisible() then                          
	function self:UpdateVisibility()
		if IsAltKeyDown() and (not IsControlKeyDown()) and (not IsShiftKeyDown()) and (not self.combatState) then
			self:Show()
		else
			self:Hide()
		end
	end            
else
self:Hide()
end

OnEvent:

if event == "PLAYER_REGEN_ENABLED" then
    self.combatState = false
elseif event == "PLAYER_REGEN_DISABLED" then
    self.combatState = true
end
self:UpdateVisibility()

OnUpdate:

if kgPanels:FetchFrame("BottomBars"):IsVisible() then      
self:Show()
else
self:Hide()
end

My Second Panel:
OnLoad:

self:RegisterEvent("MODIFIER_STATE_CHANGED")
self:RegisterEvent("PLAYER_REGEN_ENABLED")
self:RegisterEvent("PLAYER_REGEN_DISABLED")
 
if kgPanels:FetchFrame("BottomBars2"):IsVisible() then                          
	function self:UpdateVisibility()
		if IsAltKeyDown() and (not IsControlKeyDown()) and (not IsShiftKeyDown()) and (not self.combatState) then
			self:Show()
		else
			self:Hide()
		end
	end                  
else
self:Hide()
end

OnEvent:

if event == "PLAYER_REGEN_ENABLED" then
    self.combatState = false
elseif event == "PLAYER_REGEN_DISABLED" then
    self.combatState = true
end
self:UpdateVisibility()

OnUpdate:

if kgPanels:FetchFrame("BottomBars"):IsVisible() then      
self:Hide()
else
self:Show()
end

Also I am getting the following lua error when I press Alt:
