[LayaAir 2.0]释放资源与阴影冲突的问题

import Resource = Laya.Resource;

import RenderTexture = Laya.RenderTexture;



export default function destroyUnusedResourcesHack() {

    // @ts-ignore

    let idResourcesMap = Resource._idResourcesMap;

    for (let k in idResourcesMap) {

        let res = idResourcesMap[k];

        if (!(res instanceof RenderTexture) && !res.lock && res._referenceCount === 0)

            res.destroy();

    }

}
