How to immobilize this belgian unit?

[Kossatx]

Hi! I'm trying to immobilize in Brussels only belgian units that move in the hex. I've written this code, but the game crashes Any idea?

Code: Select all

local belgium = game:GetFactionById(6)
local Brussels = game:GetHex(86, 26)
if Brussels.unit ~= nil
	and unit.hex ~= nil
	and unit.hex.x == 86
	and unit.hex.y == 26
	and unit.type == Unit.LAND
	and hex.unit.faction.id == 6 then
		unit.mp = 0
end	

Code: Select all

[00:40:32][4640]Phase start: central_powers
[00:40:32][4640]**************

I've already fixed the crash writting "unit.faction.id" instead of "hex.unit.faction.id":

Code: Select all

local belgium = game:GetFactionById(6)
local Brussels = game:GetHex(86, 26)
if Brussels.unit ~= nil
	and unit.hex ~= nil
	and unit.hex.x == 86
	and unit.hex.y == 26
	and unit.type == Unit.LAND
	and unit.faction.id == 6 then
		unit.mp = 0
end
