  12. Description
  13. -----------
  14. **CharacterBody2D** is a specialized class for physics bodies that are meant to be user-controlled. They are not affected by physics at all, but they affect other physics bodies in their path. They are mainly used to provide high-level API to move objects with wall and slope detection (:ref:`move_and_slide<class_CharacterBody2D_method_move_and_slide>` method) in addition to the general collision detection provided by :ref:`PhysicsBody2D.move_and_collide<class_PhysicsBody2D_method_move_and_collide>`. This makes it useful for highly configurable physics bodies that must move in specific ways and collide with the world, as is often the case with user-controlled characters.
  15. For game objects that don't require complex movement or collision detection, such as moving platforms, :ref:`AnimatableBody2D<class_AnimatableBody2D>` is simpler to configure.

  116. Apply when there is no notion of floor or ceiling. All collisions will be reported as ``on_wall``. In this mode, when you slide, the speed will always be constant. This mode is suitable for top-down games.

  154. If ``false`` (by default), the body will move faster on downward slopes and slower on upward slopes.
  155. If ``true``, the body will always move at the same speed on the ground no matter the slope. Note that you need to use :ref:`floor_snap_length<class_CharacterBody2D_property_floor_snap_length>` to stick along a downward slope at constant speed.

  173. Sets a snapping distance. When set to a value different from ``0.0``, the body is kept attached to slopes when calling :ref:`move_and_slide<class_CharacterBody2D_method_move_and_slide>`. The snapping vector is determined by the given distance along the opposite direction of the :ref:`up_direction<class_CharacterBody2D_property_up_direction>`.
  174. As long as the snapping vector is in contact with the ground and the body moves against :ref:`up_direction<class_CharacterBody2D_property_up_direction>`, the body will remain attached to the surface. Snapping is not applied if the body moves along :ref:`up_direction<class_CharacterBody2D_property_up_direction>`, meaning it contains vertical rising velocity, so it will be able to detach from the ground when jumping or when the body is pushed up by something. If you want to apply a snap without taking into account the velocity, use :ref:`apply_floor_snap<class_CharacterBody2D_method_apply_floor_snap>`.
