Help me writing a PlayerFrame code to fade in

[Almaniarra-argent-dawn]

Hello, I am currently using the code here which I found on US forums;

Looking For Help, Want to Disappear My Original Character frame out of combat

Then I’ve added TargetFrame for more immersion;

PlayerFrame:SetAlpha(0.05)
EventRegistry:RegisterCallback("PLAYER_REGEN_DISABLED", function() 
	PlayerFrame:SetAlpha(1)
end)

EventRegistry:RegisterCallback("PLAYER_REGEN_ENABLED", function() 
	PlayerFrame:SetAlpha(0.05)
end)

PlayerFrame:HookScript("OnEnter", function(self)
	self:SetAlpha(1)
end)

PlayerFrame:HookScript("OnLeave", function(self)
	if not InCombatLockdown() then
		self:SetAlpha(0.05)
	end
end)

TargetFrame:SetAlpha(0.2)
EventRegistry:RegisterCallback("PLAYER_REGEN_DISABLED", function() 
	TargetFrame:SetAlpha(1)
end)

EventRegistry:RegisterCallback("PLAYER_REGEN_ENABLED", function() 
	TargetFrame:SetAlpha(0.2)
end)

TargetFrame:HookScript("OnEnter", function(self)
	self:SetAlpha(1)
end)

TargetFrame:HookScript("OnLeave", function(self)
	if not InCombatLockdown() then
		self:SetAlpha(0.2)
	end
end)

Now, I want to make PlayerFrame’s Alpha to 1 when i target myself but couldn’t find a way to do it.

Tried UnitisUnit but couldn’t make it work, Tried OnEvent with UNIT_TARGET: “player” too, it didn’t work neither. Also tried;

EventRegistry:RegisterCallback("PLAYER_TARGET_CHANGED", function()
    if ( UnitIsUnit("targettarget", "player") ) then
      PlayerFrame:SetAlpha(1)
end)

I have no clue about coding etc. just tried some codes with some common sense and probably making some mistakes but don’t even know what it is my mistakes. I don’t know how I can call TargetPlayer to SetAlpha(1) in this coding language.

If someone with coding knowledge can help, it will make my day.
