Extension Creation Help

[ItsCliffGaming]

I am trying to create a (what I thought would be) relatively simple Extension, that would create a new UI element to display the number of Golden d20s the party has, which is a house rule we use. I was able to get it all created in its most basic form, but the numbers do not sync between the client and the host, and I am lost on how to make that connection.

golden_d20_tracker.lua

-- Create a global variable to store the window instance
local goldenD20Window = nil

function onInit()
    -- Announce the extension loading
    ChatManager.SystemMessage("Golden d20s Extension Loaded")

    -- Create the UI
    createUI()
	
	-- Getting initial count
	goldenD20Count = DB.getValue("campaign.golden_d20_count", 0)

    -- Register a callback to update the UI when the golden d20 count changes
    DB.addHandler("campaign.golden_d20_count", "onUpdate", updateGoldenD20Count)
	
end

function createUI()
    -- Create a window to hold the Golden d20s UI
    goldenD20Window = Interface.openWindow("goldend20_window", "")
    if goldenD20Window then
        goldenD20Window.updateGoldenD20Count = updateGoldenD20Count
        goldenD20Window.increaseGoldenD20 = increaseGoldenD20
        goldenD20Window.decreaseGoldenD20 = decreaseGoldenD20
        updateGoldenD20Count()
    else
        ChatManager.SystemMessage("Failed to create Golden d20s UI")
    end
end

function increaseGoldenD20()
    local count = DB.getValue("campaign.golden_d20_count", 0)
    DB.setValue("campaign.golden_d20_count", "number", count + 1)
end

function decreaseGoldenD20()
    local count = DB.getValue("campaign.golden_d20_count", 0)
    if count > 0 then
        DB.setValue("campaign.golden_d20_count", "number", count - 1)
    end
end

function updateGoldenD20Count()
    if goldenD20Window then
        local count = DB.getValue("campaign.golden_d20_count", 0)
        goldenD20Window.golden_d20_count.setValue(count)
    end
end

            </buttoncontrol>
        </sheetdata>
    </windowclass>
</root>

Also, the other big piece that I was hoping to solve for was saving the "golden_d20_count" to an external text file, so I can call it in OBS to update/display the number to my Twitch chat.

Any and all help would be appreciated!

Any data that you want to be always be shared to the player clients has to be made public to the players. Try checking the code in CoreRPG for examples of DB.setPublic used for combattracker, party sheet and more.
