Line2D¶

Inherits: Node2D < CanvasItem < Node < Object

A 2D line.

Description¶

A line through several points in 2D space.

Note: By default, Godot can only draw up to 4,096 polygon points at a time. To increase this limit, open the Project Settings and increase ProjectSettings.rendering/limits/buffers/canvas_polygon_buffer_size_kb and ProjectSettings.rendering/limits/buffers/canvas_polygon_index_buffer_size_kb.

Methods¶

void	add_point ( Vector2 position, int at_position=-1 )
void	clear_points ( )
int	get_point_count ( ) const
Vector2	get_point_position ( int i ) const
void	remove_point ( int i )
void	set_point_position ( int i, Vector2 position )

Enumerations¶

enum LineJointMode:

LINE_JOINT_SHARP = 0 — The line’s joints will be pointy. If sharp_limit is greater than the rotation of a joint, it becomes a bevel joint instead.
LINE_JOINT_BEVEL = 1 — The line’s joints will be bevelled/chamfered.
LINE_JOINT_ROUND = 2 — The line’s joints will be rounded.

enum LineCapMode:

LINE_CAP_NONE = 0 — Don’t draw a line cap.
LINE_CAP_BOX = 1 — Draws the line cap as a box.
LINE_CAP_ROUND = 2 — Draws the line cap as a circle.

enum LineTextureMode:

LINE_TEXTURE_NONE = 0 — Takes the left pixels of the texture and renders it over the whole line.
LINE_TEXTURE_TILE = 1 — Tiles the texture over the line. The texture must be imported with Repeat enabled for it to work properly.
LINE_TEXTURE_STRETCH = 2 — Stretches the texture across the line. Import the texture with Repeat disabled for best results.

Property Descriptions¶

bool antialiased

Default	`false`
Setter	set_antialiased(value)
Getter	get_antialiased()

If true, the line’s border will be anti-aliased.

LineCapMode begin_cap_mode

Default	`0`
Setter	set_begin_cap_mode(value)
Getter	get_begin_cap_mode()

Controls the style of the line’s first point. Use LineCapMode constants.

Color default_color

Default	`Color( 0.4, 0.5, 1, 1 )`
Setter	set_default_color(value)
Getter	get_default_color()

The line’s color. Will not be used if a gradient is set.

LineCapMode end_cap_mode

Default	`0`
Setter	set_end_cap_mode(value)
Getter	get_end_cap_mode()

Controls the style of the line’s last point. Use LineCapMode constants.

Gradient gradient

Setter	set_gradient(value)
Getter	get_gradient()

The gradient is drawn through the whole line from start to finish. The default color will not be used if a gradient is set.

LineJointMode joint_mode

Default	`0`
Setter	set_joint_mode(value)
Getter	get_joint_mode()

The style for the points between the start and the end.

PoolVector2Array points

Default	`PoolVector2Array( )`
Setter	set_points(value)
Getter	get_points()

The points that form the lines. The line is drawn between every point set in this array.

int round_precision

Default	`8`
Setter	set_round_precision(value)
Getter	get_round_precision()

The smoothness of the rounded joints and caps. This is only used if a cap or joint is set as round.

float sharp_limit

Default	`2.0`
Setter	set_sharp_limit(value)
Getter	get_sharp_limit()

The direction difference in radians between vector points. This value is only used if joint mode is set to LINE_JOINT_SHARP.

Texture texture

Setter	set_texture(value)
Getter	get_texture()

The texture used for the line’s texture. Uses texture_mode for drawing style.

LineTextureMode texture_mode

Default	`0`
Setter	set_texture_mode(value)
Getter	get_texture_mode()

The style to render the texture on the line. Use LineTextureMode constants.

float width

Default	`10.0`
Setter	set_width(value)
Getter	get_width()

The line’s width.

Curve width_curve

Setter	set_curve(value)
Getter	get_curve()

The line’s width varies with the curve. The original width is simply multiply by the value of the Curve.

Method Descriptions¶

void add_point ( Vector2 position, int at_position=-1 )

Adds a point at the position. Appends the point at the end of the line.

If at_position is given, the point is inserted before the point number at_position, moving that point (and every point after) after the inserted point. If at_position is not given, or is an illegal value (at_position < 0 or at_position >= [method get_point_count]), the point will be appended at the end of the point list.

void clear_points ( )

Removes all points from the line.

int get_point_count ( ) const

Returns the Line2D’s amount of points.

Vector2 get_point_position ( int i ) const

Returns point i’s position.

void remove_point ( int i )

Removes the point at index i from the line.

void set_point_position ( int i, Vector2 position )

Overwrites the position in point i with the supplied position.
