Is there ANY way I get the global lua value from a template?

[SilentRuin]

I do not want to have to copy the entire template function (tried with super but can't get global value) here but after experimenting all over I can't find out how to not have to copy the entire CoreRPG\common\scripts\toolbar.lua as I need access to the global aButtons at the top of the file. This all comes down to the way the map toolbar buttons for Target all friends and target all foes were grouped with the clear target button. As those buttons are evil for a player (can see things they should never see) I want to turn them off and on optionally. I can turn the entire toolbar_targeting group off with very little override footprint. But to do just the two I'm not seeing a way to do it short of overrding the entire toolbar.lua file which of course means stomping anyone else using it. Even tried breaking up the crazy toolbar 30 stuff but was just as bad of an impact.

Here is what I've currently got - what I'd like to do is accomplish this exact same thing without having to override a bunch of code some other extension might be overriding... RED BOLD is code that I added... the following all works perfectly - just STOMPS the whole file.

CoreRPG\common\scripts\toolbar.lua

local nButtons = 0;
local aButtons = {};

local nButtonSize = 20;
local nButtonHorzMargin = 1;
local nButtonVertMargin = 2;

function onInit()
	if parameters then
		if parameters[1].horzmargin then
			nButtonHorzMargin = tonumber(parameters[1].horzmargin[1]) or nButtonHorzMargin;
		end
		if parameters[1].vertmargin then
			nButtonVertMargin = tonumber(parameters[1].vertmargin[1]) or nButtonVertMargin;
		end
		if parameters[1].buttonsize then
			nButtonSize = tonumber(parameters[1].buttonsize[1]) or nButtonSize;
		end
	end

	if button and type(button[1]) == "table" then
		for k, v in ipairs(button) do
			if v.id and v.icon then
				local sID = v.id[1];
				local sIcon = v.icon[1];

				local sTooltip = "";
				if v.tooltipres then
					sTooltip = Interface.getString(v.tooltipres[1]);
				elseif v.tooltip then
					sTooltip = v.tooltip[1];
				end

				addButton(sID, sIcon, sTooltip);
			end
		end
	end
	
	if self.onValueChanged then
		self.onValueChanged();
	end
	OptionsManager.registerCallback("NO_MAP_TARGETING", noMapToolbarTargeting);
end

function onClose()
	OptionsManager.unregisterCallback("NO_MAP_TARGETING", noMapToolbarTargeting);
end

function addButton(sID, sIcon, sTooltip)
	local bToggle = false;
	if toggle then
		bToggle = true;
	end
	
	local button = window.createControl("toolbar_button", "");
	if button then
		local x = nButtonHorzMargin + (nButtons * (nButtonSize + nButtonHorzMargin));
		nButtons = nButtons + 1;

		local nBarWidth = x + nButtonSize + nButtonHorzMargin;
		setAnchoredWidth(nBarWidth);
		setAnchoredHeight(nButtonSize + (2 * nButtonVertMargin));
		local w,h = getSize();

		button.setAnchor("left", getName(), "left", "absolute", x);
		button.setAnchor("top", getName(), "top", "absolute", nButtonVertMargin);
		button.setAnchoredWidth(nButtonSize);
		button.setAnchoredHeight(nButtonSize);

		button.configure(self, sID, sIcon, sTooltip, bToggle);
		
		aButtons[sID] = button;

		if isVisible() then
			button.setVisible(true);
		end
	end
end

function setActive(target)
	for id, button in pairs(aButtons) do
		if id == target then
			button.setValue(1);
		else
			button.setValue(0);
		end
	end
end

function highlightAll()
	for id, button in pairs(aButtons) do
		button.setValue(1);
	end
end

function setVisibility(bVisible)
	if Session then
		setVisible(bVisible);
		
		for id, button in pairs(aButtons) do
			if not Session.IsHost and (id == "foe" or id == "friend") and OptionsManager.isOption("NO_MAP_TARGETING", "on") then
				button.setVisible(false);
			else
				button.setVisible(bVisible);
			end
		end
	end
end

function noMapToolbarTargeting()
	if Session then
		for id, button in pairs(aButtons) do
			if not Session.IsHost and (id == "foe" or id == "friend") then
				if OptionsManager.isOption("NO_MAP_TARGETING", "on") then
					button.setVisible(false);
				else
					button.setVisible(true);
				end
			end
		end
	end
end

Still would like to know how to access a global in template lua override - but I've rewritten this much simpler and just made myself a image_toolbar_targeting_lite to switch out between image_toolbar_targeting template.

They are explicitly defined as local by design; and are not meant to be overriden. They can not be accessed externally.
