Line2D

A 2D line.

A line through several points in 2D space. Supports varying width and color over the line’s length, texturing, and several cap/joint types.

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 and ProjectSettings.rendering/limits/buffers/canvas_polygon_index_buffer_size_kb.

Methods

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.

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

• antialiased

If , the line’s border will attempt to perform antialiasing by drawing thin OpenGL smooth lines on the line’s edges.

Note: Line2D is not accelerated by batching if antialiased is true.

Note: Due to how it works, built-in antialiasing will not look correct for translucent lines and may not work on certain platforms. As a workaround, install the add-on then create an AntialiasedLine2D node. That node relies on a texture with custom mipmaps to perform antialiasing. 2D batching is also still supported with those antialiased lines.

• LineCapMode begin_cap_mode

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

• Color default_color

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

• end_cap_mode

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

• 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.

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

• PoolVector2Array points

The points that form the lines. The line is drawn between every point set in this array. Points are interpreted as local vectors.

• round_precision

The smoothness of the rounded joints and caps. Higher values result in smoother corners, but are more demanding to render and update. This is only used if a cap or joint is set as round.

Note: The default value is tuned for lines with the default width. For thin lines, this value should be reduced to a number between 2 and 4 to improve performance.

• sharp_limit

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

• Texture texture

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

• texture_mode

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

• width

The line’s width.

• Curve width_curve

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

• void add_point ( Vector2 position, 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.

• get_point_position ( int i ) const

Returns point i‘s position.

• void set_point_position ( i, Vector2 position )

Overwrites the position in point i with the supplied .
