DragUpdateEvent class

Constructors

DragUpdateEvent(int pointerId, Game game, DragUpdateDetails details)

Properties

canvasDelta → Vector2
Event delta in the coordinate space of the game widget, i.e. relative to the game canvas.
latefinalinherited
canvasEndPosition → Vector2
Event end position in the coordinate space of the game widget, i.e. relative to the game canvas.
latefinalinherited
canvasPosition → Vector2
latefinalinherited
canvasStartPosition → Vector2
Event start position in the coordinate space of the game widget, i.e. relative to the game canvas.
latefinalinherited
continuePropagation ↔ bool
If this flag is false (default), the event will be delivered to the first component that can handle it. If that component sets this flag to true, the event will propagate further down the component tree to other eligible components.
