**Inherits:** :ref:`Node2D<class_Node2D>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

Node that represents collision shape data in 2D space.

.. rst-class:: classref-introduction-group

Description
-----------

Editor facility for creating and editing collision shapes in 2D space. Set the :ref:`shape<class_CollisionShape2D_property_shape>` property to configure the shape. **IMPORTANT**: this is an Editor-only helper to create shapes, use :ref:`CollisionObject2D.shape_owner_get_shape<class_CollisionObject2D_method_shape_owner_get_shape>` to get the actual shape.

You can use this node to represent all sorts of collision shapes, for example, add this to an :ref:`Area2D<class_Area2D>` to give it a detection shape, or add it to a :ref:`PhysicsBody2D<class_PhysicsBody2D>` to create a solid object.

Property Descriptions
---------------------

.. _class_CollisionShape2D_property_disabled:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **disabled** = ``false``

.. rst-class:: classref-property-setget

- void **set_disabled** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_disabled** **(** **)**

A disabled collision shape has no effect in the world. This property should be changed with :ref:`Object.set_deferred<class_Object_method_set_deferred>`.

.. rst-class:: classref-item-separator

----

.. _class_CollisionShape2D_property_one_way_collision:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **one_way_collision** = ``false``

.. rst-class:: classref-property-setget

- void **set_one_way_collision** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_one_way_collision_enabled** **(** **)**

Sets whether this collision shape should only detect collision on one side (top or bottom).

\ **Note:** This property has no effect if this **CollisionShape2D** is a child of an :ref:`Area2D<class_Area2D>` node.

.. rst-class:: classref-item-separator

----

.. _class_CollisionShape2D_property_one_way_collision_margin:

.. rst-class:: classref-property

:ref:`float<class_float>` **one_way_collision_margin** = ``1.0``

.. rst-class:: classref-property-setget

- void **set_one_way_collision_margin** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_one_way_collision_margin** **(** **)**

The margin used for one-way collision (in pixels). Higher values will make the shape thicker, and work better for colliders that enter the shape at a high velocity.

.. rst-class:: classref-item-separator

----

.. _class_CollisionShape2D_property_shape:

.. rst-class:: classref-property

:ref:`Shape2D<class_Shape2D>` **shape**

.. rst-class:: classref-property-setget

- void **set_shape** **(** :ref:`Shape2D<class_Shape2D>` value **)**
- :ref:`Shape2D<class_Shape2D>` **get_shape** **(** **)**

The actual shape owned by this collision shape.

.. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)`
.. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)`
.. |vararg| replace:: :abbr:`vararg (This method accepts any number of arguments after the ones described here.)`
.. |static| replace:: :abbr:`static (This method doesn't need an instance to be called, so it can be called directly using the class name.)`
