Thank you @Spynaz for a great module. I was wondering if you or anyone could help me solve this problem relating to the module.
I believe my issue has to do with the UIScale and changing the size of the GUI. BEFORE changing the scale size, you can see the dragging frame locks onto the mouse while dragging. AFTER changing the scale, the dragging frame gets a strange offset.
Note: I need to keep the UIScale.
local UDim2_new = UDim2.new
local UserInputService = game:GetService("UserInputService")
local DraggableObject = {}
DraggableObject.__index = DraggableObject
-- Sets up a new draggable object
function DraggableObject.new(Object)
local self = {}
self.Object = Object
self.DragStarted = nil
self.DragEnded = nil
self.Dragged = nil
self.Dragging = false
setmetatable(self, DraggableObject)
return self
end
-- Enables dragging
function DraggableObject:Enable()
local object = self.Object
local dragInput = nil
local dragStart = nil
local startPos = nil
local preparingToDrag = false
-- Updates the element
local function update(input)
local delta = input.Position - dragStart
local newPosition = UDim2_new(startPos.X.Scale, startPos.X.Offset + delta.X, startPos.Y.Scale, startPos.Y.Offset + delta.Y)
object.Position = newPosition
return newPosition
end
self.InputBegan = object.InputBegan:Connect(function(input)
if input.UserInputType == Enum.UserInputType.MouseButton1 or input.UserInputType == Enum.UserInputType.Touch then
preparingToDrag = true
--[[if self.DragStarted then
self.DragStarted()
end
dragging = true
dragStart = input.Position
startPos = Element.Position
--]]
local connection
connection = input.Changed:Connect(function()
if input.UserInputState == Enum.UserInputState.End and (self.Dragging or preparingToDrag) then
self.Dragging = false
connection:Disconnect()
if self.DragEnded and not preparingToDrag then
self.DragEnded()
end
self:ZIndexOverlap(-10)
preparingToDrag = false
end
end)
end
end)
self.InputChanged = object.InputChanged:Connect(function(input)
if input.UserInputType == Enum.UserInputType.MouseMovement or input.UserInputType == Enum.UserInputType.Touch then
dragInput = input
end
end)
self.InputChanged2 = UserInputService.InputChanged:Connect(function(input)
if object.Parent == nil then
self:Disable()
return
end
if preparingToDrag then
preparingToDrag = false
if self.DragStarted then
self.DragStarted()
end
self.Dragging = true
dragStart = input.Position
startPos = object.Position
end
if input == dragInput and self.Dragging then
local newPosition = update(input)
if self.Dragged then
self.Dragged(newPosition)
end
end
end)
end
-- Disables dragging
function DraggableObject:Disable()
self.InputBegan:Disconnect()
self.InputChanged:Disconnect()
self.InputChanged2:Disconnect()
if self.Dragging then
self.Dragging = false
if self.DragEnded then
self.DragEnded()
end
end
end
return DraggableObject
