Converting a turf system to a different group system?

[Lergen]

Hello, I'm fairly new to this. I'm trying to learn to convert the GTWTurf system (https://github.com/404rq/GTW-RPG/tree/master/[resources]/GTWturf) to use Castillo's gang system (https://community.multitheftauto.com×/index.php?p=resources&s=details&id=1514). I think I have it working, but the turf colors won't update to use the exported gang colors. What am I doing wrong? I'm guessing the problem is in this:

				        local playerGang = getElementData (player, "gang" )
						if ( playerGang ) then
					    local r, g, b = unpack ( getGangColor ( playerGang ) )
						setRadarAreaColor(area, tonumber(r), tonumber(g), tonumber(b), 175)
						setRadarAreaFlashing(area, false)
						setElementData(theTurf, "currAttacker", nil)
						dbExec(db, "UPDATE turfs SET owner=?, red=?, green=?, blue=? WHERE X=? AND Y=?", gang, r, g, b,
						tonumber(getElementData(colCuboid,"posx")), tonumber(getElementData(colCuboid,"posy")))
						end
					end, time_to_capture*1000, 1)
				end
			end

 

I'm using Sasuke's turfsystem, which does use Castillo's gang system, as a reference:

function ( player )
		if turfElement[source] and source == turfElement[source][1] then
			local turf,area,id = unpack( turfElement[source] )
			local playerGang = getElementData ( player, "gang" )
			local turfGang = executeSQLQuery("SELECT GangOwner FROM Turf_System WHERE Turfs=?", "Turf["..tostring(id).."]" )
			if ( turfGang[1].GangOwner == playerGang ) then
				outputChatBox( messages[2]:format( turfGang[1].GangOwner or "None" ), player, 0, 255, 0, false )
			else
				local playerGang = getElementData ( player, "gang" )
				setElementData( source, "warTurf", playerGang )
				if ( isTimer ( turfTimer[source][1] ) ) then
					if isTimer( turfTimer[source][2] ) then killTimer( turfTimer[source][2] ) end 
					return 
				end
				if ( playerGang ) then
					local r, g, b = unpack ( getGangColor ( playerGang ) )
					-- local r, g, b = 255, 255, 255
					setRadarAreaFlashing ( area, true )
					if turfGang[1].GangOwner ~= "Nadie" then
						outputChatBox( messages[3]:format( turfGang[1].GangOwner ), player, 0, 255, 0, false )
					else
						outputChatBox( messages[4], player, 0, 255, 0, false )
					end
					
					turfTimer[source][1] = setTimer (
						function ( )
							local players = getGangPlayersInTurf ( turf, playerGang )
							setRadarAreaColor ( area, tonumber(r), tonumber(g), tonumber(b), 175 )
							for _, player in ipairs ( players ) do
								outputChatBox( messages[5], player, 0, 255, 0, false )
								triggerClientEvent(player, "onTakeTurf", player)
								givePlayerMoney ( player, 4000 )
								executeSQLQuery("UPDATE Turf_System SET GangOwner=?,r=?,g=?,b=? WHERE Turfs=?", playerGang, tonumber(r), tonumber(g), tonumber(b), "Turf["..tostring(id).."]" )
								-- setElementData ( turf, "getTurfGang", playerGang )
							end
							setRadarAreaFlashing ( area, false )
						end
					,120000, 1)
				end
			end
		end
	end

 

In the debug I get badargument at getelementdata [expected element at argument 1, got nil].

I'd greatly appreciate any advice.
