- CanvasItem,
|

- CanvasItem节点,CanvasItem -> Node -> Object
|
||||
- Canvas是画布的意思,所以CanvasItem代表了就是可以被绘制节点,可以设置可视化界面和材质的颜色
|
||||
- 所有的2D节点和GUI节点都继承于CanvasItem节点

- Texture类,Resource -> Reference -> Object
|
||||
- Texture 贴图,附加到物体表面的贴图,实际上就是包含一张Image图片
|
||||
- 可以用在3D模型中当作贴图,或者2D的Sprite中当作图片,或者GUI的背景
