Struct bevy::input::touch::TouchInput
pub struct TouchInput {
pub phase: TouchPhase,
pub position: Vec2,
pub force: Option<ForceTouch>,
pub id: u64,
}
Expand description
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::Cancelled
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.
