  10. A 2D game object, inherited by all 2D-related nodes. Has a position, rotation, scale, and Z index.
  11. Description
  12. -----------
  13. A 2D game object, with a transform (position, rotation, and scale). All 2D nodes, including physics objects and sprites, inherit from Node2D. Use Node2D as a parent node to move, scale and rotate children in a 2D project. Also gives control of the node's render order.

  210. .. _class_Node2D_method_look_at:
  211. - void **look_at** **(** :ref:`Vector2<class_Vector2>` point **)**
  212. Rotates the node so it points towards the ``point``, which is expected to use global coordinates.
  213. ----
  214. .. _class_Node2D_method_move_local_x:
  215. - void **move_local_x** **(** :ref:`float<class_float>` delta, :ref:`bool<class_bool>` scaled=false **)**
  216. Applies a local translation on the node's X axis based on the :ref:`Node._process<class_Node_method__process>`'s ``delta``. If ``scaled`` is ``false``, normalizes the movement.

  228. Transforms the provided local position into a position in global coordinate space. The input is expected to be local relative to the ``Node2D`` it is called on. e.g. Applying this method to the positions of child nodes will correctly transform their positions into the global coordinate space, but applying it to a node's own position will give an incorrect result, as it will incorporate the node's own transformation into its global position.
  229. ----
  230. .. _class_Node2D_method_to_local:
  231. - :ref:`Vector2<class_Vector2>` **to_local** **(** :ref:`Vector2<class_Vector2>` global_point **)** |const|
  232. Transforms the provided global position into a position in local coordinate space. The output will be local relative to the ``Node2D`` it is called on. e.g. It is appropriate for determining the positions of child nodes, but it is not appropriate for determining its own position relative to its parent.
  233. ----
  234. .. _class_Node2D_method_translate:
  235. - void **translate** **(** :ref:`Vector2<class_Vector2>` offset **)**
  236. Translates the node by the given ``offset`` in local coordinates.
