Member Variables
----------------

  .. _class_Line2D_begin_cap_mode:

- :ref:`LineCapMode<enum_line2d_linecapmode>` **begin_cap_mode** - Controls the style of the line's first point. Use ``LINE_CAP\_\*`` constants. Default value: ``LINE_CAP_NONE``.

  .. _class_Line2D_default_color:

- :ref:`Color<class_color>` **default_color** - The line's color. Will not be used if a gradient is set.

  .. _class_Line2D_end_cap_mode:

- :ref:`LineCapMode<enum_line2d_linecapmode>` **end_cap_mode** - Controls the style of the line's last point. Use ``LINE_CAP\_\*`` constants. Default value: ``LINE_CAP_NONE``.

  .. _class_Line2D_gradient:

- :ref:`Gradient<class_gradient>` **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.

  .. _class_Line2D_joint_mode:

- :ref:`LineJointMode<enum_line2d_linejointmode>` **joint_mode** - The style for the points between the start and the end.

  .. _class_Line2D_points:

- :ref:`PoolVector2Array<class_poolvector2array>` **points** - The points that form the lines. The line is drawn between every point set in this array.

  .. _class_Line2D_round_precision:

- :ref:`int<class_int>` **round_precision** - The smoothness of the rounded joints and caps. This is only used if a cap or joint is set as round.

  .. _class_Line2D_sharp_limit:

- :ref:`float<class_float>` **sharp_limit** - The direction difference in radians between vector points. This value is only used if ``joint mode`` is set to ``LINE_JOINT_SHARP``.

  .. _class_Line2D_texture:

- :ref:`Texture<class_texture>` **texture** - The texture used for the line's texture. Uses ``texture_mode`` for drawing style.

  .. _class_Line2D_texture_mode:

- :ref:`LineTextureMode<enum_line2d_linetexturemode>` **texture_mode** - The style to render the ``texture`` on the line. Use ``LINE_TEXTURE\_\*`` constants. Default value: ``LINE_TEXTURE_NONE``.

  .. _class_Line2D_width:

- :ref:`float<class_float>` **width** - The line's width.


Enums
-----

  .. _enum_Line2D_LineCapMode:

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_Line2D_LineTextureMode:

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.

  .. _enum_Line2D_LineJointMode:

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.


Description
-----------

A line through several points in 2D space.

Member Function Description
---------------------------

.. _class_Line2D_add_point:

- void **add_point** **(** :ref:`Vector2<class_vector2>` position **)**

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

.. _class_Line2D_get_point_count:

- :ref:`int<class_int>` **get_point_count** **(** **)** const

Returns the Line2D's amount of points.

.. _class_Line2D_get_point_position:

- :ref:`Vector2<class_vector2>` **get_point_position** **(** :ref:`int<class_int>` i **)** const

Returns point ``i``'s position.

.. _class_Line2D_remove_point:

- void **remove_point** **(** :ref:`int<class_int>` i **)**

Remove the point at index ``i`` from the line.

.. _class_Line2D_set_point_position:

- void **set_point_position** **(** :ref:`int<class_int>` i, :ref:`Vector2<class_vector2>` position **)**

Overwites the position in point ``i`` with the supplied ``position``.
