To enable this, you can either add the TouchSimulation MonoBehaviour to a GameObject in your scene or simply call TouchSimulation.Enable somewhere in your startup code. Touch input can be simulated from input on other kinds of Pointer devices such as Mouse and Pen devices. The bulk of the data is stored in unmanaged memory that is indexed by wrapper structs. Note: The Touch and Finger APIs don't generate GC garbage. See EnhancedTouch.Touch API documentation for more details. This lets you track how a specific touch moves over the screen, which is useful if you want to implement recognition of specific gestures. You can use Touch.activeTouches to get an array of all currently active touches. All records in a touch have the same touchId. Between those two points, an arbitrary number of PointerPhase.Moved and/or PointerPhase.Stationary records exist. You can use Touch.activeFingers to get an array of all currently active fingers.īy touch: Each touch is a single finger contact with at least a beginning point ( PointerPhase.Began) and an endpoint ( PointerPhase.Ended or PointerPhase.Cancelled). The EnhancedTouch.Touch API is designed to provide access to touch information along two dimensions:īy finger: Each finger is defined as the Nth contact source on a Touchscreen. You only need to call EnhancedTouchSupport.Enable() if you want to use the EnhancedTouch.Touch API. Note: Touch and Touchscreen don't require EnhancedTouchSupport to be enabled. Can be called from MonoBehaviour.Awake(), for example. To enable it, call EnhancedTouchSupport.Enable(): using The EnhancedTouch.Touch class provides enhanced touch support. If you bind a single Action to input from multiple touches, you should set the Action type to pass-through so the Action gets callbacks for each touch, instead of just one. Alternatively, use a wildcard Binding to bind one Action to all touches: /touch*/press. However, if you want to get input from multiple touches in your Action, you can bind to individual touches by using Bindings like /touch3/press. This gets input from the primary touch, and any other non-touch pointer Devices. To do this, bind to the pointer Controls, like /press or /delta. You can use touch input with Actions, like any other Pointer Device. You can use this to detect double- and multi-tap gestures. Reports the number of consecutive tap reports from the OS. This allows you to distinguish individual touches.Ī Control that reports the current TouchPhase of the touch.Ī button Control that reports whether the OS recognizes a tap gesture from this touch. The size of the area where the finger touches the surface. Normalized pressure with which the finger is currently pressed while in contact with the pointer surface. The time when the finger first touched the surface. The position where the finger first touched the surface. The difference in position since the last frame. If you need an API that only represents active touches, see the higher-level EnhancedTouch.Touch class.Įach TouchControl on the Device, including primaryTouch, is made up of the following child Controls: Control This array has a fixed size, regardless of how many touches are currently active. The touches array contains all the touches that the system can track. PrimaryTouch is always identical to one of the entries in the touches array. This is usually the first finger that touches the screen. The primaryTouch Control represents the touch which is currently driving the Pointer representation, and which should be used to interact with the UI. Each of these represents a potential finger touching the Device. The primary touch drives the Pointer representation on the Device.Īn array of touch Controls that represents all the touches on the Device.Ī touch screen Device consists of multiple TouchControls. ControlsĪdditional to the Controls inherited from Pointer, touch screen Devices implement the following Controls: ControlĪ touch Control that represents the primary touch of the screen. To query the touch screen that was last used or last added, use Touchscreen.current. Touch screens are based on the Pointer layout. Touchscreen DeviceĪt the lowest level, a touch screen is represented by an InputSystem.Touchscreen Device which captures the touch screen's raw state. #TOUCHE EXAMPLE WINDOWS#Touch input is supported on Android, iOS, Windows, and the Universal Windows Platform (UWP). high-level support implemented in the EnhancedTouch.Touch class.low-level support implemented in the Touchscreen class.
