希望给 Sprite 组件增加一个 可被子类覆盖的 getAssembler() 方法

Use Case

例如:

   getAssembler (): IAssembler {
        return  Sprite.Assembler.getAssembler(this);
    }

    protected _flushAssembler (): void {
        const self = this;
        const assembler = this.getAssembler();

        if (self._assembler !== assembler) {
            self.destroyRenderData();
            self._assembler = assembler;
        }
        // ......
    }

有了这个方法后, 开发者就可以在自己的项目里 继承Sprite, 并使用自己的 Assembler .

Additional Information

Start by locating the Sprite component and its _flushAssembler method, then inspect Sprite.Assembler.getAssembler(this) and the IAssembler type shown in the issue. Confirm how subclasses could provide a custom Assembler without breaking existing behavior. Done means Sprite exposes an overridable getAssembler() method and the existing assembler flow continues to work.
