Gui not dragging properly

Help and Feedback Scripting Support
#1

I have an imagebutton inside a frame that when I click and drag it will follow, this works perfectly when it is not parented with the frame. When it’s in the frame the gui will skip and go in the opposite direction of the mouse.

		local InventoryGui = script.Parent
		local InventoryFrame = InventoryGui.Inventory
		--local Topbar = InventoryGui.TopToolbar
		
		local Dragging = false
		
		for i,v in pairs(InventoryFrame:GetChildren()) do
			
			if v:IsA("ImageButton") then
				
				v.InputBegan:Connect(function(input)
					
					if input.UserInputType == Enum.UserInputType.MouseButton1 then
						Dragging = true
					end
					
				end)
				
				v.InputChanged:Connect(function(input)
					
					if input.UserInputType == Enum.UserInputType.MouseButton1 then
						
						v.Position = UDim2.new(0, input.Position.X, 0, input.Position.Y)
						print(input.Position)
					end
					
				end)
				
				v.InputEnded:Connect(function(input)
					
					if input.UserInputType == Enum.UserInputType.MouseButton1 then
						
						v.Position = UDim2.new(0, input.Position.X, 0, input.Position.Y)
						Dragging = false
					end
					
				end)
			end

This may be because you’re not using the “Dragging” variable in a useful way and not setting the UserInputType in InputChanged to Enum.UserInputType.MouseMovement. The GUIObject.InputChanged event should also be replaced to it’s UserInputService equivalent to handle mouse movement outside of the GUIObject.
local InventoryGui = script.Parent
local InventoryFrame = InventoryGui.Inventory
–local Topbar = InventoryGui.TopToolbar

local Dragging = false

for i,v in pairs(InventoryFrame:GetChildren()) do
    if v:IsA("ImageButton") then
        v.InputBegan:Connect(function(input)
            if input.UserInputType == Enum.UserInputType.MouseButton1 then
                Dragging = true
            end
        end)

        game:GetService("UserInputService").InputChanged:Connect(function(input)

                if input.UserInputType == Enum.UserInputType.MouseMovement and Dragging then
                    v.Position = UDim2.new(0, input.Position.X, 0, input.Position.Y)
                    print(input.Position)
                end
        end)

        v.InputEnded:Connect(function(input)
            if input.UserInputType == Enum.UserInputType.MouseButton1 then
                v.Position = UDim2.new(0, input.Position.X, 0, input.Position.Y)
                Dragging = false
            end
        end)
    end
end

Sorry for the bad formatting.

It’s moving all the images instead of one?

Whoops, I forgot you had more than one image. Updated code:
local InventoryGui = script.Parent
local InventoryFrame = InventoryGui.Inventory
–local Topbar = InventoryGui.TopToolbar

local Dragging = false
local SelectedDraggable

for i,v in pairs(InventoryFrame:GetChildren()) do
    if v:IsA("ImageButton") then
        v.InputBegan:Connect(function(input)
            if input.UserInputType == Enum.UserInputType.MouseButton1 then
                SelectedDraggable = v
                Dragging = true
            end
        end)

        game:GetService("UserInputService").InputChanged:Connect(function(input)

                if input.UserInputType == Enum.UserInputType.MouseMovement and Dragging and SelectedDraggable then
                    SelectedDraggable.Position = UDim2.new(0, input.Position.X, 0, input.Position.Y)
                    print(input.Position)
                end
        end)

        v.InputEnded:Connect(function(input)
            if input.UserInputType == Enum.UserInputType.MouseButton1 then
                v.Position = UDim2.new(0, input.Position.X, 0, input.Position.Y)
                Dragging = false
                SelectedDraggable = nil
            end
        end)
    end
end

What I did here is that I added a variable called “SelectedDraggable”. It’s set on the InputBegan event. You wanted only one image to move, right? So, the InputChanged event instead checks for that new variable to be declared, and if it was, move the selected draggable to the mouse’s position.

A solution probably better than this

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
YourImageButton.MouseButton1Down:Connect(function()
    YourImageButton.Position = UDim.fromOffset(mouse.X, mouse.Y)
end)
