# Add physics to a sprite with 2D Physics Core

> Add a Physics Area Sprite component to derive physics shapes automatically from a sprite's physics outline.

To add physics to a sprite GameObject and match the shape of the sprite for collisions, add a Physics Area Sprite component.

> **Note:**
>
> This documentation is about using Pose, Area, and Constraint components. To use 2D physics in the Unity Editor using components like the Rigidbody 2D component, refer to [2D physics](/engine/6000.7/manual/unity2d/2d-physics.md.md) instead.

## Add a Physics Area Sprite component

To add the component, follow these steps:

1. Select a GameObject with a Sprite Renderer component.
2. In the Editor window, select **Add Component**, then select **Physics 2D (Core)** > **Physics Pose**.
3. Select **Add Component** again, then select **Physics 2D (Core)** > **Physics Area Sprite**.

Unlike other Physics Area components, the **Physics Area Sprite** component has no **Geometry** properties. Instead, the component copies the [Custom Physics Outline](/engine/6000.7/manual/unity2d/sprite/sprite-editor-window-reference/custom-physics-shape-editor-reference.md) of a sprite.

## Edit the shape

To edit the shape the component uses, follow these steps:

1. Select the sprite in the **Project** window.
2. In the **Inspector** window, select **Sprite Editor**.
3. In the dropdown, select **Custom Physics Outline**.
4. Edit the shape. For more information, refer to [Custom Physics Outline tab reference for the Sprite Editor window](/engine/6000.7/manual/unity2d/sprite/sprite-editor-window-reference/custom-physics-shape-editor-reference.md).
5. To save your changes, select **Apply**.

If you add multiple shapes but the physics object has fewer shapes than you expect, check the **Rejected Shape Count** property in the **Info** section of the **Physics Area Sprite** component. If Unity rejected shapes, check the custom physics outline for unneeded extra points on a straight line, or points that are too close together.
