Last post for today!
I saw this cool video later today, and found this nice explanation of spring forces on a 2D plane. So I tried learning something new and add onto what I already had learnt, just with a few tweaks and created this!
Try for yourself!

Source -
local spring = {}
function spring.new(bob)
local center = workspace.CurrentCamera.ViewportSize/2
local disp = 200
local y = 250
local k = .01
local v = Vector2.new(0, 0)
local anch = Vector2.new(center.x, 0)
local pos = center + bob.AbsoluteSize/2
local gravity = Vector2.new(0, .1)
local damp = 0.998
game:GetService("RunService").Heartbeat:Connect(function()
if game:GetService("UserInputService"):IsMouseButtonPressed(Enum.UserInputType.MouseButton1) then
local mousepos = game:GetService("UserInputService"):GetMouseLocation()
bob.Position = UDim2.new(0, mousepos.x, 0, mousepos.y)
pos = mousepos
v = Vector2.new(0, 0)
else
bob.Position = UDim2.new(0, pos.x, 0, pos.y)
local force = pos - anch
local mag = force.magnitude - disp
force = force.Unit
force = force * -1 * k * mag
v += force + gravity
pos += v
v = v * damp
end
end)
end
return spring
Thanks!
