Sprite.Type 在大部分时候能用吧…… 我看之前的设计思路像是把这些类型放在静态属性上

是的. 你说的对 . Sprite.Type 是值, 但是要用到类型时, 总是要 typeof Sprite.Type 很烦.

我这里确实说写了. 应该是

export type { SpriteType } from './sprite';

类似的还有

export type { PixelFormat, TextureFilter, WrapMode } from './asset-enum';

他们对应的值是 cc.RenderTexture.PixelFormat/Filter/WrapMode.

不过这个事情 倒是也可以让 开发者自己在项目里 类给类型设置别名 来解决.

export type SpriteType = typeof cc.Sprite.Type;
export type PixelFormat = typeof cc.RenderTexture.PixelFormat;
export type TextureFilter = typeof cc.RenderTexture.Filter;
export type WrapMode = typeof cc.RenderTexture.WrapMode;

所以这个 PR 倒也不是必须.

不过 有些重要的 类或者值 确实没有导出, 导致开发者难以在项目中进行使用(继承 聚合 实例化 类型声明等).
比如

export type { IBatcher } from './i-batcher';
export type { Batcher2D } from './batcher-2d';

export { StaticVBAccessor, StaticVBChunk } from './static-vb-accessor';
export { RenderDrawInfo, RenderDrawInfoType } from './render-draw-info';
export { RenderEntity, RenderEntityType, RenderEntityFillColorType } from './render-entity';
export { Stage, StencilManager } from './stencil-manager';

还有

export { TextureBase } from './texture-base';

export type { Batcher2D } from './batcher-2d';

这个最可怕 在deprecated.ts里重命名为 UI 导出了……
