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.
