Colour Wheel Rendering

Help and Feedback Scripting Support
#1

Hi there. I’m currently trying to render a colour wheel in roblox (draw it from scratch). Currently, it’s going not terrible BUT not how I wanted it to go.

The issue is seen here:

It starts off well then just cuts off. I would like to know how to fix this, any solutions?

We’re definitely not going to be able to help you fix the script unless you post the code here.

#3 

local rs = game:GetService("RunService")

local h, s, v = 0, 0, 1

function polar(v)
	return math.atan2(v.y, v.x), v.magnitude
end
	
function toDeg(x)
	return (x * (180 / math.pi))
end

local pixels = 1

local rows = wheel.Size.Y.Offset

for i = 0, rows, pixels do
	for j = 0, wheel.Size.X.Offset, pixels do
		local new_colour = Instance.new("Frame", wheel)
		new_colour.BorderSizePixel = 0
		new_colour.Size = UDim2.new(0, pixels, 0, pixels)
		new_colour.Position = UDim2.new(0, j, 0, i)
		local r = wheel.AbsoluteSize.X / 2
		local d = Vector2.new(new_colour.AbsolutePosition.X, new_colour.AbsolutePosition.Y) - wheel.AbsolutePosition -  wheel.AbsoluteSize/2
		if (d:Dot(d) > r * r) then
			d = d.unit * r
		end
		print(r, d)
		local phi, len = polar(d * Vector2.new(1, -1))
		h, s = toDeg(phi)/360, len / r
		new_colour.BackgroundColor3 = Color3.fromHSV(h, s, v)
		rs.Heartbeat:Wait()
	end
end

I am not sure why but the wheel looks a bit like a block rather than a thin cylinder tipped on its side as in wheel shaped. Wont fix your script but will make the view appear to be in line with it.

I was just rendering it as a block prior to making it circle. Could you help me with rendering it as this… weird cyclind you mentioned? ^-^

Can you please show us the explorer view of wheel.
