Struct bevy::prelude::TouchInput

pub struct TouchInput {
    pub phase: TouchPhase,
    pub position: Vec2,
    pub force: Option<ForceTouch>,
    pub id: u64,
}

A touch input event.

Logic

Every time the user touches the screen, a new TouchPhase::Started event with an unique identifier for the finger is generated. When the finger is lifted, the TouchPhase::Ended event is generated with the same finger id.

After a TouchPhase::Started event has been emitted, there may be zero or more TouchPhase::Moved events when the finger is moved or the touch pressure changes.

The finger id may be reused by the system after an TouchPhase::Ended event. The user should assume that a new TouchPhase::Started event received with the same id has nothing to do with the old finger and is a new finger.

A TouchPhase::Canceled event is emitted when the system has canceled tracking this touch, such as when the window loses focus, or on iOS if the user moves the device against their face.

Note

This event is the translated version of the WindowEvent::Touch from the winit crate. It is available to the end user and can be used for game logic.

Fields

phase: TouchPhase

The phase of the touch input.

position: Vec2

The position of the finger on the touchscreen.

force: Option<ForceTouch>

Describes how hard the screen was pressed.

May be None if the platform does not support pressure sensitivity. This feature is only available on iOS 9.0+ and Windows 8+.

id: u64

The unique identifier of the finger.
