How to check if i can to move a unit onto a plot? (Lua)

[killmeplease]

I have tried CanMoveOrAttackInto(plot) but it always returns false (not working?).
I can check manually all the conditions e.g. if a plot is impassable and if there are another units but maybe theres another function which does all those checks? what function does UI use for example?

thanks!

It's bugged, Firaxis forget to actually return the C++ result to the Lua API!

pUnit:CanMoveOrAttackInto(pPlot) is identical to pUnit:CanMoveThrough(pPlot), but the latter actually returns the result!

thanks! i will use it.
its name looked like its not suitable

well... CanMoveThrough determines if a unit can move through a tile but not if it can stay there.
so i have written a lua func not ideal maybe.. at least i think there should be a better way to determine a caravan unit.

function CanMoveOnto(unit, plot)
	if plot:IsWater() then
		return unit:CanEmbarkOnto(unit:GetPlot(), plot);
	end
	if plot:IsImpassable() then
		return false;
	end
	for i = 0, plot:GetNumUnits() do
		local other = plot:GetUnit(i);
		if other ~= nil and not GameInfo.Units[other:GetUnitType()].Immobile -- caravan
		and (other:IsCombatUnit() == unit:IsCombatUnit() or other:GetOwner() ~= unit:GetOwner()) then
			return false;
		end
	end
	return true;
end

ps: another thing i learned was that if you call JumpToNearestValidPlot on a caravan unit it will brake it wont be able to do anything anymore just sitting in the city blocking it for civilians. so dont do this
