Events

GAMEPAD_CONNECTED

Emits when a gamepad is connected to the device.

Example

world.events.addListener(world.events.globalId, ecs.input.GAMEPAD_CONNECTED, (detail: Object) => {
    console.log(detail.gamepad);
});

GAMEPAD_DISCONNECTED

Emits when a gamepad is disconnected from the device.

Example

world.events.addListener(world.events.globalId, ecs.input.GAMEPAD_DISCONNECTED, (detail: Object) => {
    console.log(detail.gamepad);
});

メモ

• Multiple touch points can be active simultaneously.
• Only one touch gesture (single or multitouch) will be recognized as active at a time.

インフォメーション

If a touch event has a target, it will be emitted on that target and propagate up to its parent elements and eventually to the global level. This means a touch listener on a parent object will capture events from all its child elements.

SCREEN_TOUCH_START

Emits when the user initially touches or clicks the screen or target object.

Example

world.events.addListener(world.events.globalId, ecs.input.SCREEN_TOUCH_START, (touchEvent: TouchEvent) => {
    console.log(touchEvent);
});

SCREEN_TOUCH_MOVE

Emits when the user clicks and drags or moves their finger on the screen.

Example

world.events.addListener(world.events.globalId, ecs.input.SCREEN_TOUCH_MOVE, (touchEvent: TouchEvent) => {
    console.log(touchEvent);
});

SCREEN_TOUCH_END

Emits when the user stops clicking or lift the finger off the screen.

Example

world.events.addListener(world.events.globalId, ecs.input.SCREEN_TOUCH_END, (touchEvent: TouchEvent) => {
    console.log(touchEvent);
});

インフォメーション

Gesture events are emitted when the user makes a "gesture" on the phone screen. A gesture is any action that requires multiple fingers. If the user starts with a "'zoom" action (2 fingers moving away from each other) then adds another finger to the screen then the "zoom" gesture will end and a new one will start with 3 fingers.

GESTURE_START

Emits when the user stops clicking or lift the finger off the screen.

Example

world.events.addListener(world.events.globalId, ecs.input.GESTURE_START, (gestureEvent: GestureEvent) => {
    console.log(gestureEvent);
});

GESTURE_MOVE

Emits when the user moves their finger(s) on the screen.

Example

world.events.addListener(world.events.globalId, ecs.input.GESTURE_MOVE, (gestureEvent: GestureEvent) => {
    console.log(gestureEvent);
});

GESTURE_END

Emits when the number of fingers change from an previous gesture check.

Example

world.events.addListener(world.events.globalId, ecs.input.GESTURE_END, (gestureEvent: GestureEvent) => {
    console.log(gestureEvent);
});
