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 have 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 need to 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.

Description

A line through several points in 2D space.

Property Descriptions

LineCapMode begin_cap_mode

Setter	set_begin_cap_mode(value)
Getter	get_begin_cap_mode()

Controls the style of the line’s first point. Use LINE_CAP_* constants. Default value: LINE_CAP_NONE.

Color default_color

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

Setter	set_end_cap_mode(value)
Getter	get_end_cap_mode()

Controls the style of the line’s last point. Use LINE_CAP_* constants. Default value: LINE_CAP_NONE.

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

Setter	set_joint_mode(value)
Getter	get_joint_mode()

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

PoolVector2Array points

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

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

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

Setter	set_texture_mode(value)
Getter	get_texture_mode()

The style to render the texture on the line. Use LINE_TEXTURE_* constants. Default value: LINE_TEXTURE_NONE.

float width

Setter	set_width(value)
Getter	get_width()

The line’s width.

Method Descriptions

void add_point ( Vector2 position )

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

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 )

Remove 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.
