| name | String | The name of the shape which can be not unique. It is required for each shape in G6 3.3. Besides, `name` can be used for searching this shape, e.g. `const shape = group.find(element => element.name === 'shape-name')`. The usage of find can be found at [find(fn)](#findfn) |
| draggable | Boolean | Whether the shape is allowed to response `dragstart`, `drag`, and `dragend` events. E.g. when user add a shape into a custom node with `draggable: true`, the shape will response the dragging events on the node, and the `'drag-node'` in the `modes` of the graph instance will take effect |
| zIndex | Number | The visual index of the shape, similar to z-index of DOM. It is not required. `group.sort()` will sort the visual index of the shapes inside the group according to their zIndex |

### G6 3.3
在 G6 3.3 及以上版本中，废弃了 Group / Canvas 上只适用于三阶矩阵的变换函数:
After G6 3.3, the following transform methods are discarded:
- 🗑 平移函数 translate；
- 🗑 移动函数 move；
- 🗑 缩放函数 scale；
- 🗑 旋转函数 rotate；
- 🗑 以 (0, 0) 点为中心的旋转函数 rotateAtStart。
- 🗑 translate;
- 🗑 move;
- 🗑 scale;
- 🗑 rotate;
- 🗑 rotateAtStart: rotate the shape or group with center (0, 0)。
在 G6 3.3 版本中要应用矩阵变换的效果，需要手动设置矩阵的值: • 设置矩阵 setMatrix(matrix)； • 重置矩阵 resetMatrix()； • 设置矩阵 attr('matrix', matrix)；
To achive some transformation in G6 3.3, you should set the matrix value manually:
- Get the current matrix of a shape or a group: getMatrix();
- Set the matrix to a shape or a group: setMatrix(matrix) or attr('matrix', matrix);
- Reset the matrix: resetMatrix().
为了方面使用，我们提供了矩阵变换的工具方法:
We provide the function for transformantion:
```javascript
import { transform } from '@antv/matrix-util';
// 3*3 矩阵变换，用于二维渲染
// transform a 3*3 matrix
trasform(m, [
['t', x, y], // translate
['t', x, y], // translate with vector (x, y)
['r', Math.PI], // rotate
['s', 2, 2], // scale
['s', 2, 2], // scale at x-axis and y-axis
]);
```
#### Example
The following code registers a custom node with a transfromed rect with: translation with vector `(100, 50)`, rotating with angle `Math.PI / 4`, maginifying 2 times on x-axis and 0.5 times on y-axis:
```javascript
import { transform, mat3 } from '@antv/matrix-util';
G6.registerNode('example', {
drawShape: (cfg, group) => {
const rect = group.addShape('rect', {
attrs: {
width: 100,
height: 100,
x: 100,
y: 100,
fill: '#9EC9FF',
stroke: '#5B8FF9',
lineWidth: 3,
},
// must be assigned in G6 3.3 and later versions. it can be any value you want
name: 'rect-shape',
});
const matrix = rect.getMatrix();
// the init matrix for a shape or a group is null, initiate it with unit matrix
if (!matrix) matrix = mat3.create();
// transform a 3*3 matrix
const newMatrix = trasform(matrix, [
[ 't', 100, 50 ], // translate
[ 'r', Math.PI / 4 ], // rotate
[ 's', 2, 0.5 ], // scale
]);
rect.setMatrix(newMatrix);
}
});
```

```javascript
import { transform, mat3 } from '@antv/matrix-util';
G6.registerNode('example', {
drawShape: (cfg, group) => {
const rect = group.addShape('rect', {
attrs: {

},
// must be assigned in G6 3.3 and later versions. it can be any value you want
name: 'rect-shape',
draggable: true
});
const matrix = rect.getMatrix();
// 图形或分组的初始矩阵时 null，为了避免变换一个 null 矩阵，需要通过 mat3.create() 将其初始化为单位矩阵
if (!matrix) matrix = mat3.create();
// 3*3 矩阵变换，用于二维渲染
const newMatrix = trasform(matrix, [
[ 't', 100, 50 ], // translate
[ 'r', Math.PI / 4 ], // rotate

rect.setMatrix(newMatrix);
}

- 如果不从任何现有的节点扩展新节点时，`draw` 方法是必须的；
- `update` 方法可以不定义，数据更新时会走 `draw` 方法，所有图形清除重绘；
- 节点内部所有图形**使用相对于节点自身的坐标系**，即 `(0, 0)` 是该节点的中心。而节点的坐标是相对于画布的，由该节点 group 上的矩阵控制，自定义节点中不需要用户感知。详见例子 [从无到有定义节点](#1-从无到有定义节点)；
- `update` 方法可以不定义：
- 当 `update` 未定义：若指定了 `registerNode` 的第三个参数 `extendNodeName`（即代表继承指定的内置节点类型），则节点更新时将执行被继承的内置节点类型的 `update` 逻辑；若未指定 `registerNode` 的第三个参数，则节点更新时会执行 `draw` 方法，所有图形清除重绘；
- 当定义了 `update` 方法，则不论是否指定 `registerNode` 的第三个参数，在节点更新时都会执行复写的 `update` 函数逻辑。
- `afterDraw`，`afterUpdate` 方法一般用于扩展已有的节点，例如：在矩形节点上附加图片，圆节点增加动画等；
- `setState` 方法一般也不需要复写，有全局的样式可以替换；
