  11. A 2D game object, inherited by all 2D-related nodes. Has a position, rotation, scale, and Z index.
  12. Description
  13. -----------
  14. 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.

  224. - void **global_translate** **(** :ref:`Vector2<class_Vector2>` offset **)**
  225. Adds the ``offset`` vector to the node's global position.

  227. .. _class_Node2D_method_look_at:
  228. - void **look_at** **(** :ref:`Vector2<class_Vector2>` point **)**
  229. Rotates the node so it points towards the ``point``, which is expected to use global coordinates.
  230. ----
  231. .. _class_Node2D_method_move_local_x:
  232. - void **move_local_x** **(** :ref:`float<class_float>` delta, :ref:`bool<class_bool>` scaled=false **)**
  233. 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.
  234. ----
  235. .. _class_Node2D_method_move_local_y:
  236. - void **move_local_y** **(** :ref:`float<class_float>` delta, :ref:`bool<class_bool>` scaled=false **)**
  237. Applies a local translation on the node's Y axis based on the :ref:`Node._process<class_Node_method__process>`'s ``delta``. If ``scaled`` is ``false``, normalizes the movement.

  239. .. _class_Node2D_method_rotate:

  245. 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.
  246. ----
  247. .. _class_Node2D_method_to_local:
  248. - :ref:`Vector2<class_Vector2>` **to_local** **(** :ref:`Vector2<class_Vector2>` global_point **)** |const|
  249. 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.
  250. ----
  251. .. _class_Node2D_method_translate:
  252. - void **translate** **(** :ref:`Vector2<class_Vector2>` offset **)**
