Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
While this card is face-up on your side of the field, your opponent cannot select a face-up monster as an attack target except "Decoyroid".
--デコイロイド
--Decoyroid
local s,id=GetID()
function s.initial_effect(c)
	--cannot be battle target
	local e1=Effect.CreateEffect(c)
	e1:SetType(EFFECT_TYPE_FIELD)
	e1:SetRange(LOCATION_MZONE)
	e1:SetTargetRange(0,LOCATION_MZONE)
	e1:SetCode(EFFECT_CANNOT_SELECT_BATTLE_TARGET)
	e1:SetValue(s.atlimit)
	c:RegisterEffect(e1)
end
s.listed_names={id}
function s.atlimit(e,c)
	return not c:IsCode(id) and c:IsFaceup()
end
