Custom handles aren't working as supposed

Help and Feedback Scripting Support
#1

Hello, As everyone knows you can’t use Handles in viewportframes, so I created an script which will copy an part from ReplicatedStorage and gives it the right Size. All good, but as I had no idea to see what is the Magnitude from the last position of the mouse and the new one, and I just used the Position’s (Ray’s end position). It works pretty well, but if the .Adornee Is an big part, it will just be beetwen 2-4 studs. I think the problem is in this part:

        local IsFound,Data,Pos = data.IsMouseInRay()
		if IsFound and UIS:IsMouseButtonPressed(Enum.UserInputType.MouseButton1) then
           if LastPosition > (Data.Object.Position-Pos).Magnitude and LastType == Data.Id or LastPosition < (Data.Object.Position-Pos).Magnitude and LastType == Data.Id then
               LastPosition = (Data.Object.Position-Pos).Magnitude
               MouseDrag:Fire(Data.Id,LastPosition)
            elseif LastType ~= Data.Id then
               LastType = Data.Id
               LastPosition = (Data.Object.Position-Pos).Magnitude 
            elseif (Data.Object.Position-Pos).Magnitude == LastPosition then
               LastPosition = (Data.Object.Position-Pos).Magnitude 
           end
		end

The entire script if you want to see it:

local HandlesModule = {}
local Handles = {}
Handles.__index = Handles
local UIS = game:GetService("UserInputService")
local Model = Instance.new("Model")

  ["Top"] = Vector3.new(0, 1, 0);
  ["Bottom"]= Vector3.new(0, -1, 0);
  ["Back"] = Vector3.new(0, 0, 1);
  ["Front"] = Vector3.new(0, 0, -1);
  ["Right"] = Vector3.new(1, 0, 0);
  ["Left"]  = Vector3.new(-1, 0, 0)
}

local Types = {[1] = "Z",[2] = "Y",[3] = "X"}

 ["Resize"] = "StudsResize";

}

	local ToModel = Instance.new("Model")
	Inst:Clone().Parent = ToModel
	return ToModel
end

			local Type = Types[i]
			local Size = Size / 2
			Vector = Vector3.new(Size,Size,Size)
			break
		end
	end
	return Vector
end

            Object.Parent = Origin
            Object.Name = EnumId

	elseif Type == "Resize" then

return HandlesModule

It is an Module script. Sorry for bad scripting but I’m pretty new to scripting :confused:

The code is a little confusing - not your fault necessarily, just a lot of things happening for my brain to take in after school right now haha.

But here’s a way to check the magnitude of the last position of the mouse to the new position that I believe should work:

local player = -- Whichever player you specify
local mouse = Player:GetMouse()

local lastPos = nil
local currentPos = nil

local switch = false

while true do
    if switch == false then
        lastPos = Vector2.new(mouse.X, mouse.Y)
        switch = true
    else
        currentPos = Vector2.new(mouse.X, mouse.Y)
        switch = false
    end

    if lastPos and currentPos then
        local magnitude = (lastPos - currentPos).Magnitude
        -- Do whatever you want with it
    end
end

And if you want to find out how .Magnitude works mathematically, I made a post with a formula I made for it that works pretty much the same way, just not for Roblox Lua, but vanilla Lua. Here: How does magnitude and range work? - #6 by MJTFreeTime

Hope I helped ya out!

Sorry, but I arleady done this using an different Math. I will give you the Solution anyways
