How would i detect if a item/part is on a plot?

#1

Im working on a plot/placement system, And to stop exploiters from placing items anywhere i wanna detect if the item is on the plot.

#2

You can see if the item’s position is within the plot range

#3

Yea how exactly would i do that

#4

See if this helps:

#5

You can either check its Childrens by using YourModel:GetChildren() or you can just use the wood’s solution.

#6

Well it doesnt matter where the parent of the item is, Im talking about the position.

#7

Can you explain correctly what your trying to achieve? You might want to save the Positions?

#8

So in a placement system you place a item the item is placed in the position which is determined from the client (in my situation) which means they can set the position anywhere i am trying to only allow them to set the position on their plot.

#9

You can use spatial queries to determine if a part’s entire hitbox is within the plot’s allowed zone

#10

Is there a part like rectangle that is the zone? If so then you can just tell whether the point you provide is in the rectangle.

How to detect if a part is completely within another part?

Assuming no rotation to the parts this should work for balls and blocks.

function isInPart(part,posVec)
	if part.Shape == Enum.PartType.Block then
		local xDist = math.abs(posVec.X-part.Position.X)
		local yDist = math.abs(posVec.Y-part.Position.Y)
		local zDist = math.abs(posVec.Z-part.Position.Z)
		if xDist <= part.Size.X/2 and yDist <= part.Size.Y/2 and zDist <= part.Size.Z/2 then
			return true
		else
			return false
		end
	elseif part.Shape == Enum.PartType.Ball then
		if (part.Position-posVec).Magnitude <= (part.Size.X/2) then
			return true
		else
			return false
		end
	end
	--elseif part.Shape == Enum.PartType.Cylinder then -- Commented because this only works if the cylinder is up right
		--local horizontalDist = Vector2.new(part.Position.X-posVec.X,part.Position.Z-posVec.Z).Magnitude
		--local yDist = math.abs(posVec.Y-part.Position.Y)
		--if yDist <= part.Size.Y/2 and horizontalDist <= part.Size.X then
			--return true
		--else
			--return false
		--end
	--end
end
