GestureInfo

The gesture info is carried by gesture event, record the info of one gesture.

Type	Name	Interface Description
Variables	duration: number	• Function: The duration of long-tap gesture. Only valid for LongTap gesture. The value is in milliseconds.
Variables	endPoint: Vector2f	• Function: The gesture end position of this gesture. Valid for all gesture types. The value is 0 - 1. 0 is the top-left corner of the screen. 1 is the bottom-right corner of the screen.
Variables	firstTrigger: boolean	• Function: Start dragging. When a drag-and-drop action occurs, a series of Drag events will be received. This flag can be used to obtain the event that triggered the drag-and-drop action. Only valid when gesture type is Drag.
Variables	startPoint: Vector2f	• Function: The gesture start position of this gesture. Only valid when gesture type is Drag or Drop. The value is 0 - 1. 0 is the top-left corner of the screen. 1 is the bottom-right corner of the screen.
Variables	type: GestureType	• Function: The gesture type of this gesture.
Functions	constructor()

Examples

firstTrigger: boolean

Control the position of an object by drag gesture.
const gestureEmitter = APJS.EventManager.getGestureEmitter();
const dragCallback = (event:APJS.IEvent) => {
  const gestureInfo = event.args[0] as APJS.GestureInfo;
  if (gestureInfo.firstTrigger) {
    this.currentDragStartPoint = gestureInfo.startPoint;
    this.startAnchoredPosition = this.imageTransform.anchoredPosition;
  }
  const offset = gestureInfo.endPoint.clone().subtract(this.currentDragStartPoint);
  this.imageTransform.anchoredPosition = offset.multiply(new APJS.Vector2f(screenResolution.x, -screenResolution.y)).add(this.startAnchoredPosition);
}
gestureEmitter.on(APJS.GestureType.Drag, dragCallback);

constructor()

let obj = new APJS.GestureInfo();

Use Case

@component()
export class NewBehaviourScript extends APJS.BasicScriptComponent {
  onStart() {
    // TODO: instantiate / use GestureInfo here
  }
  onUpdate(deltaTime: number) {
  }
}
