是否已休眠 A flag that indicates whether the body is considered sleeping. A sleeping body acts similar to a static body, except it is only temporary and can be awoken. If you need to set a body as sleeping, you should use `Sleeping.set` as this requires more than just setting this flag.

#### setCentre

▸ **setCentre**(`centre`, `relative?`): `void`

设置中心点 Set the centre of mass of the body. The `centre` is a vector in world-space unless `relative` is set, in which case it is a translation. The centre of mass is the point the body rotates about and can be used to simulate non-uniform density. This is equal to moving `body.position` but not the `body.vertices`. Invalid if the `centre` falls outside the body's convex hull.

#### setParts

▸ **setParts**(`parts`, `autoHull?`): `void`

设置成员 Sets the parts of the `body` and updates mass, inertia and centroid. Each part will have its parent set to `body`. By default the convex hull will be automatically computed and set on `body`, unless `autoHull` is set to `false.` Note that this method will ensure that the first part in `body.parts` will always be the `body`.

***

#### setVertices

▸ **setVertices**(`vertices`): `void`

设置顶点 Sets the body's vertices and updates body properties accordingly, including inertia, area and mass (with respect to `body.density`). Vertices will be automatically transformed to be orientated around their centre of mass as the origin. They are then automatically translated to world space based on `body.position`.

The `vertices` argument should be passed as an array of `Matter.Vector` points (or a `Matter.Vertices` array). Vertices must form a convex hull, concave hulls are not supported.

**Parameters**

| Name       | Type                                                                               |

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://engine-docs.meta4d.me/jkUDC53bibxMH5jKxZe0/api-docs/api-docs/classes/m4m.framework.rectbody2d.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
