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.

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)…
