A strange shape generator that I made for Teverse.

Shape.lua

function drawPoint (x, y, z)
	local b = engine.block("New block " ..math.floor(x))
	b.parent = engine.workspace
	b.colour = colour(0, 0.5, 0.5)
	b.position = vector3(x, y, z)
end

function drawCircle (z, r, detail)

local x, y = 0, 0
for i = 1, 360, detail do
  local angle = i * math.pi / 180
  local ptx, pty = x + r * math.cos( angle ), y + r * math.sin( angle )
  drawPoint( ptx, pty, z)
end
end


function generateCone (radius, offset, detailReducer, distance)
	-- Actual code: distance is just the total offset since start
	if not distance then  distance = 0 end
	if not detailReducer then detailReducer = 1 end
	if not offset then offset = 5 end
	while radius > 0 do
		drawCircle(distance, radius, detailReducer)
		-- Now we increment/decrement
		distance = distance + offset
		radius = radius - 5
		wait(.5)
	end
end


-- we pass in offset (a fixed incrementing value) 
-- And the Radius of the new circle
-- We want to repeat until the radius is 0.
-- Lower detailReducer value = more detail. No parts is divided by this value (approx.). Making it whole is recomended.

-- One side
generateCone(100, nil, 4 )
generateCone(75, nil, 3)
generateCone(50, nil, 2)

-- Other side
generateCone(100, -5, 4, -5)
generateCone(75, -5, 3, -5)
generateCone(50, -5, 2, -5)
