@cesium-extends/subscriber/dist/index.d.ts

该包提供了一种方便的方式，用于在 Cesium 场景中订阅事件。它允许您为指定的实体添加事件监听器，并在发生事件时触发回调函数。

import { Cartesian2, Viewer, Entity } from 'cesium';

interface EventArgs {
    position?: Cartesian2;
    endPosition?: Cartesian2;
    startPosition?: Cartesian2;
    [name: string]: any;
}
type ListenCallback<T> = (movement: EventArgs, substance: T) => void;
type ExternalListenCallback = (movement: EventArgs, result: any) => void;
type EventType = 'LEFT_DOWN' | 'LEFT_UP' | 'LEFT_CLICK' | 'LEFT_DOUBLE_CLICK' | 'RIGHT_DOWN' | 'RIGHT_UP' | 'RIGHT_CLICK' | 'MIDDLE_DOWN' | 'MIDDLE_UP' | 'MIDDLE_CLICK' | 'MOUSE_MOVE' | 'WHEEL' | 'PINCH_START' | 'PINCH_MOVE' | 'PINCH_END';
