好了

[minggo]

但是这个改动修改了接口，破坏了兼容性了。

[wingcd]

之前那个就有问题，只支持一个子网格，新版本可以直接用这个，实在不行可以新增一个接口？

[minggo]

新增接口比较好。

[minggo]

理论上 createDynamicMesh 是 createDynamicMeshes 的特例。那能用 createDynamicMeshes 实现 createDynamicMesh 吗？

[wingcd]

当然可以的

[minggo]

我的意思是类似这样的代码

static createDynamicMesh(...) {
    ...
    createDynamicMeshes(...);
}

[wingcd]

好的。可以，其实特例的参数就没用了而已
