How To Connect 2 Frames With Path2D?

[TheRobloxGato]

I’ve been struggling to make something like an arrow from one frame to another. And it needs to be automatic so I could just add one more frame and they will connect with eachother.

What do I want to achieve?
A new Path2D (or anything that can be automated through code or function like I want) Instance, which connects two frames when the function is fired.

Pretty rough example:
Squares are frames
Arrows are the Instance.new(“Path2D”)

Any help is appreciated! I hope I explained enough to understand

You can use path2D:SetControlPoints.

Example:

local path2D = Instance.new("Path2D", script.Parent)
path2D.Thickness = 5
path2D.Color3 = Color3.fromRGB(0, 155, 255)

local frame1 = script.Parent.Frame1
local frame2 = script.Parent.Frame2
local frame3 = script.Parent.Frame3

path2D:SetControlPoints({
	Path2DControlPoint.new(frame1.Position),
	Path2DControlPoint.new(frame2.Position),
	Path2DControlPoint.new(frame3.Position),
})

Make sure the frames AnchorPoint is (0.5, 0.5) so the lines are exactly in the middle

If you want to insert a new control point use path2D:InsertControlPoint

Example:

local path2D = Instance.new("Path2D", script.Parent)
path2D.Thickness = 5
path2D.Color3 = Color3.fromRGB(0, 155, 255)

local frame1 = script.Parent.Frame1
local frame2 = script.Parent.Frame2
local frame3 = script.Parent.Frame3

path2D:InsertControlPoint(#path2D:GetControlPoints() + 1, Path2DControlPoint.new(frame1.Position))
path2D:InsertControlPoint(#path2D:GetControlPoints() + 1, Path2DControlPoint.new(frame2.Position))
path2D:InsertControlPoint(#path2D:GetControlPoints() + 1, Path2DControlPoint.new(frame3.Position))

Big thank you! It worked for me from the first try, gotta figure out how to insert this into the main code block!

Btw here’s what i got from copy & pasting the script:
