<brief_description>
A 2D game object, inherited by all 2D-related nodes. Has a position, rotation, scale, and Z index.
</brief_description>
<description>
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.

<methods>
<method name="apply_scale">
<return type="void" />
<param index="0" name="ratio" type="Vector2" />
<description>
Multiplies the current scale by the [param ratio] vector.
</description>
</method>
<method name="get_angle_to" qualifiers="const">
<return type="float" />
<param index="0" name="point" type="Vector2" />
<description>
Returns the angle between the node and the [param point] in radians.

</description>
</method>
<method name="get_relative_transform_to_parent" qualifiers="const">
<return type="Transform2D" />
<param index="0" name="parent" type="Node" />
<description>
Returns the [Transform2D] relative to this node's parent.
</description>
</method>
<method name="global_translate">
<return type="void" />
<param index="0" name="offset" type="Vector2" />
<description>
Adds the [param offset] vector to the node's global position.
</description>
</method>
<method name="look_at">
<return type="void" />
<param index="0" name="point" type="Vector2" />
<description>
Rotates the node so that its local +X axis points towards the [param point], which is expected to use global coordinates.
[param point] should not be the same as the node's position, otherwise the node always looks to the right.
</description>
</method>
<method name="move_local_x">
<return type="void" />
<param index="0" name="delta" type="float" />
<param index="1" name="scaled" type="bool" default="false" />
<description>
Applies a local translation on the node's X axis based on the [method Node._process]'s [param delta]. If [param scaled] is [code]false[/code], normalizes the movement.
</description>
</method>
<method name="move_local_y">
<return type="void" />
<param index="0" name="delta" type="float" />
<param index="1" name="scaled" type="bool" default="false" />
<description>
Applies a local translation on the node's Y axis based on the [method Node._process]'s [param delta]. If [param scaled] is [code]false[/code], normalizes the movement.
</description>
</method>
<method name="rotate">
<return type="void" />
<param index="0" name="radians" type="float" />
<description>
Applies a rotation to the node, in radians, starting from its current rotation.
</description>
</method>
<method name="to_global" qualifiers="const">
<return type="Vector2" />
<param index="0" name="local_point" type="Vector2" />
<description>
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.
</description>
</method>
<method name="to_local" qualifiers="const">
<return type="Vector2" />
<param index="0" name="global_point" type="Vector2" />
<description>
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.
</description>
</method>
<method name="translate">
<return type="void" />
<param index="0" name="offset" type="Vector2" />
<description>
Translates the node by the given [param offset] in local coordinates.

Position, relative to the node's parent.

<member name="rotation" type="float" setter="set_rotation" getter="get_rotation" default="0.0">
Rotation in radians, relative to the node's parent.
[b]Note:[/b] This property is edited in the inspector in degrees. If you want to use degrees in a script, use [member rotation_degrees].
