问题描述
我正在尝试使用具有以下签名的onSuccess回调：
onSuccess: (task: MeshAssetTask) => void;
这意味着它接受一个接收MeshAssetTask的函数，但不返回任何内容（无效）。
meshTask.onSuccess(function (task: BABYLON.MeshAssetTask) { });
我收到此打字稿编译器错误。
Argument of type '(task: MeshAssetTask) => void' is not assignable to parameter of type 'MeshAssetTask'.
Type '(task: MeshAssetTask) => void' is missing the following properties from type 'MeshAssetTask': name,meshesNames,rootUrl,sceneFilename,and 18 more.
但是我不太明白这个错误的含义，它们应该是同一类型...
这是我的tsconfig.json

我正在使用babylon.js 4.1版
解决方法
哦...签名不是说onSuccess是一个带有函数的现有函数，它仅仅是可以分配一个函数的属性。
这会解决
meshTask.onSuccess =函数（任务：BABYLON.MeshAssetTask）{...}
