Lua code for adding markers [Solved]

I'm trying to make a quick script that adds a marker arrow to a unit when that unit uses a certain weapon, and removes it when the unit uses the weapon again. Unfortunately I'm a bit rusty. I've gotten this far:

Hidden/Spoiler:

[code]	IsEntityMarked = 0

	mark = OnCharacterDispenseControllable(

	function(character, controllable)

		if GetEntityClass(controllable) == FindEntityClass("rep_bldg_inf_marker") then

			charunit = GetCharacterUnit(character)

			if IsEntityMarked = 0 then -- This is line 98.

				MapAddEntityMarker(charunit, "hud_objective_icon", 3.0, 1, "YELLOW", true)

				IsEntityMarked = 1 

			elseif IsEntityMarked = 1 then

				MapRemoveEntityMarker(charunit)

				IsEntityMarked = 0

			end

		end

	end

	)[/code][/size]

But the error log complains:

Hidden/Spoiler:

C:\BF2_ModTools\data_FTG\_BUILD\Common\..\..\..\ToolsFL\Bin\luac.exe: ..\..\common\scripts\FTG\FTGc_con.lua:98: `then' expected near `='

As far as I can see, I've done nothing wrong - but I don't have much faith in my own analysis. Trying to attach the marker to the character, rather than the unit, had the same result.

When the variable is in an If statement, it needs == instead of = to say "is equal to".

Code: Select all

if IsEntityMarked == 0 then

Ah yes, that should fix it. Thank you; I'll mark this solved.
