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

描述

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.

Property Descriptions

Vector2 global_position

  • void set_global_position ( Vector2 value )

  • Vector2 get_global_position ( )

Global position.

float global_rotation

  • void set_global_rotation ( float value )

  • float get_global_rotation ( )

Global rotation in radians.

float global_rotation_degrees

  • void set_global_rotation_degrees ( float value )

  • float get_global_rotation_degrees ( )

Helper property to access global_rotation in degrees instead of radians.

Vector2 global_scale

  • void set_global_scale ( Vector2 value )

  • Vector2 get_global_scale ( )

Global scale.

float global_skew

  • void set_global_skew ( float value )

  • float get_global_skew ( )

Global skew in radians.

Transform2D global_transform

Global Transform2D.

Vector2 position = Vector2(0, 0)

Position, relative to the node's parent.

float rotation = 0.0

  • void set_rotation ( float value )

  • float get_rotation ( )

Rotation in radians, relative to the node's parent.

Note: This property is edited in the inspector in degrees. If you want to use degrees in a script, use rotation_degrees.

float rotation_degrees

  • void set_rotation_degrees ( float value )

  • float get_rotation_degrees ( )

Helper property to access rotation in degrees instead of radians.

Vector2 scale = Vector2(1, 1)

The node's scale. Unscaled value: (1, 1).

Note: Negative X scales in 2D are not decomposable from the transformation matrix. Due to the way scale is represented with transformation matrices in Godot, negative scales on the X axis will be changed to negative scales on the Y axis and a rotation of 180 degrees when decomposed.

float skew = 0.0

  • void set_skew ( float value )

  • float get_skew ( )

Slants the node.

Note: Skew is X axis only.

Transform2D transform

Local Transform2D.

Method Descriptions

void apply_scale ( Vector2 ratio )

Multiplies the current scale by the ratio vector.

float get_angle_to ( Vector2 point ) const

Returns the angle between the node and the point in radians.

Illustration of the returned angle.

Transform2D get_relative_transform_to_parent ( Node parent ) const

Returns the Transform2D relative to this node's parent.

void global_translate ( Vector2 offset )

Adds the offset vector to the node's global position.

void look_at ( Vector2 point )

Rotates the node so it points towards the point, which is expected to use global coordinates.

void move_local_x ( float delta, bool scaled=false )

Applies a local translation on the node's X axis based on the Node._process's delta. If scaled is false, normalizes the movement.

void move_local_y ( float delta,
