为 Minecraft Script API 中的部分接口创建了 wrapper，并提供简单的事件管理器和任务管理器，另附有一些便于代码编写的一些小工具。

export class EntityWraps {
    static map = new WeakMap();
    static classWraps = new Map();
    static prototypeWraps = new Map();
    static srcClassWraps = new Map();
    static srcPrototypeWraps = new Map();
    static fromSourceEntity(entity) {
        const srcProto = Object.getPrototypeOf(entity);
        const wrappedClass = this.prototypeWraps.get(srcProto);
        if (!wrappedClass)
            return null;
        let wrappedEntity = this.map.get(entity);
        if (!wrappedEntity) {
            wrappedEntity = new wrappedClass(entity);
            this.map.set(entity, wrappedEntity);
        }
        return wrappedEntity;
    }
    static registerWrap(entityClass, originalEntityClass) {
        const srcProto = originalEntityClass.prototype;
        const proto = entityClass.prototype;
        this.classWraps.set(originalEntityClass, entityClass);
        this.prototypeWraps.set(srcProto, entityClass);
        this.srcClassWraps.set(entityClass, originalEntityClass);
        this.srcPrototypeWraps.set(proto, originalEntityClass);
    }
    static unregisterWrap(originalEntityClass) {
        const srcProto = originalEntityClass.prototype;
        const entityClass = this.classWraps.get(originalEntityClass);
        const proto = entityClass.prototype;
        this.classWraps.delete(originalEntityClass);
        this.prototypeWraps.delete(srcProto);
        this.srcClassWraps.delete(entityClass);
        this.srcPrototypeWraps.delete(proto);
    }
}
