How to use CVars in functions?

suicidalkatt · 12-09-09, 06:41 PM

So with the new changes to 3.3 there are new cvars for

nameplateShowEnemy
nameplateShowEnemyPets
nameplateShowEnemyGuardians
nameplateShowEnemyTotems
nameplateShowFriend
nameplateShowFriendPets
nameplateShowFriendGuardians
nameplateShowFriendTotems
nameplateAllowOverlap

Have been incorporated.

I'm fairly new to scripting Lua and I'm not sure how to use the GetCVar an SetCvar API functions.

Since most CVars return a "1" or "0" they're not considered booleans. I saw the GetCVarBool() function and I'm not sure exactly how to incorporate it.

For example I used to have a saved variable returning true or false for a toggle in my ace 3 options:

Code:

totems = {
	order = 1,
	type = "toggle",
	name = L["Show Totems"],
	desc = L["Toggles the showing and hiding of All totem nameplates."],
	get = function() return self.db.profile.showtotems end,
	set = function(info,val) 
		self.db.profile.showtotems = not self.db.profile.showtotems
		if self.db.profile.showtotems then return print("-->>Totem Nameplates are now |cff00ff00ON!|r<<--") else return print("-->>Totem Nameplates are now |cffff0000OFF!|r<<--") end
		end
},

Could it be simplified to:

Code:

totems = {
	order = 1,
	type = "toggle",
	name = L["Show Totems"],
	desc = L["Toggles the showing and hiding of All totem nameplates."],
	get = function() return GetCVarBool("nameplateShowEnemyTotems") end,
	set = function(info,val) 
		if GetCVarBool("nameplateShowEnemyTotems") then
			SetCVar("nameplateShowEnemyTotems", 0, "scriptCVar")
		else
			SetCVar("nameplateShowEnemyTotems", 1, "scriptCVar")
		end
	end
},

??

I tried this and I get the toggle to show accurately, however changing the value for it in the options doesn't seem to set the CVar.

Where am I failing?

AFAIK, the interface options will only reflect cvars on reloadui.

Should I use the cvar method? and just set a saved variable to w/e the cvar of the player is?

Your second code would work ok, but you don't need "scriptCVar" there.

Edit:

Code:

set = function()
    SetCVar("nameplateShowEnemyTotems",abs(GetCVar("nameplateShowEnemyTotems")-1))
end

Kk that makes more sense, however what should I have my get function to?

CombatNames is coded to change CVAR for enemy nameplate visibility in/out of combat. You can use that as an example.

Still unsure of a good method for giving an alternate yet Cvar accurate return for Ace 3 Options.
