## プロパティ

- `UIDragDetector.ActivatedCursorIcon: ContentId`：Sets the cursor icon to display when the mouse is activated over the parent of this UIDragDetector.
- `UIDragDetector.ActivatedCursorIconContent: Content`：Sets the cursor icon to display when the mouse is activated over the parent of this UIDragDetector. Only supports asset URIs
- `UIDragDetector.BoundingBehavior: UIDragDetectorBoundingBehavior`：Determines bounding behavior of the dragged UI object when the detector's Class.UIDragDetector.BoundingUI|BoundingUI is set.
- `UIDragDetector.BoundingUI: GuiBase2d`：Instance whose bounding area defines the drag boundaries for the parent GuiObject.
- `UIDragDetector.CursorIcon: ContentId`：Sets the cursor icon to display when the mouse is hovered over the parent of this UIDragDetector.
- `UIDragDetector.CursorIconContent: Content`：Sets the cursor icon to display when the mouse is hovered over the parent of this UIDragDetector. Only asset URIs are supported.
- `UIDragDetector.DragAxis: Vector2`：The drag axis for the UIDragDetector instance when Class.UIDragDetector.DragStyle|DragStyle is set to UIDragDetectorDragStyle.TranslateLine.
- `UIDragDetector.DragRelativity: UIDragDetectorDragRelativity`：Sets the paradigm which defines the relativity of inputs/outputs from a custom drag function.
- `UIDragDetector.DragRotation: float`：The rotation performed by the current drag.
- `UIDragDetector.DragSpace: UIDragDetectorDragSpace`：Sets the paradigm which defines the space of inputs/outputs from a custom drag function.
- `UIDragDetector.DragStyle: UIDragDetectorDragStyle`：The paradigm used to generate proposed motion.
- `UIDragDetector.DragUDim2: UDim2`：The translation performed by the current drag expressed in a UDim2 value.
- `UIDragDetector.Enabled: boolean`：Whether the UIDragDetector responds to user input.
- `UIDragDetector.MaxDragAngle: float`：Along with Class.UIDragDetector.MinDragAngle|MinDragAngle, impedes the detector's attempts to generate rotational motion.
- `UIDragDetector.MaxDragTranslation: UDim2`：Along with Class.UIDragDetector.MinDragTranslation|MinDragTranslation, impedes the detector's attempts to generate linear/planar motion.
- `UIDragDetector.MinDragAngle: float`：Along with Class.UIDragDetector.MaxDragAngle|MaxDragAngle, impedes the detector's attempts to generate rotational motion.
- `UIDragDetector.MinDragTranslation: UDim2`：Along with Class.UIDragDetector.MaxDragTranslation|MaxDragTranslation, impedes the detector's attempts to generate linear/planar motion.
- `UIDragDetector.ReferenceUIInstance: GuiObject`：A GuiObject instance whose local space and absolute center position is the reference space and origin for the detector.
- `UIDragDetector.ResponseStyle: UIDragDetectorResponseStyle`：The paradigm used to define the response to proposed motion.
- `UIDragDetector.SelectionModeDragSpeed: UDim2`：Maximum drag speed for translation.
- `UIDragDetector.SelectionModeRotateSpeed: float`：Maximum angle per second the UIDragDetector can rotate at.
- `UIDragDetector.UIDragSpeedAxisMapping: UIDragSpeedAxisMapping`：UIDragSpeedAxisMapping value that determines the **X**/**Y** dimension dragging speeds.

## メソッド

- `UIDragDetector:AddConstraintFunction(priority: int, function: Function): RBXScriptConnection`：Adds a function to modify or constrain proposed motion.
- `UIDragDetector:GetReferencePosition(): UDim2`：Returns the reference UDim2 position of the current drag's reference origin.
- `UIDragDetector:GetReferenceRotation(): float`：Returns the reference rotation of the current drag's reference element.
- `UIDragDetector:SetDragStyleFunction(function: Function): ()`：Passes a function to be used if and only if Class.UIDragDetector.DragStyle|DragStyle is set to UIDragDetectorDragStyle.Scriptable.

## イベント

- `UIDragDetector.DragContinue(inputPosition: Vector2)`：Fires when a user continues dragging the UI element after Class.UIDragDetector.DragStart|DragStart has been initiated.
- `UIDragDetector.DragEnd(inputPosition: Vector2)`：Fires when a user stops dragging the UI element.
- `UIDragDetector.DragStart(inputPosition: Vector2)`：Fires when a user starts dragging the UI element.
