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_Line2D_LineCapMode: .. _class_Line2D_constant_LINE_CAP_NONE: .. _class_Line2D_constant_LINE_CAP_BOX: .. _class_Line2D_constant_LINE_CAP_ROUND: 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_Line2D_LineTextureMode: .. _class_Line2D_constant_LINE_TEXTURE_NONE: .. _class_Line2D_constant_LINE_TEXTURE_TILE: .. _class_Line2D_constant_LINE_TEXTURE_STRETCH: 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. :ref:`CanvasItem.texture_repeat` of the ``Line2D`` node must be :ref:`CanvasItem.TEXTURE_REPEAT_ENABLED` or :ref:`CanvasItem.TEXTURE_REPEAT_MIRROR` for it to work properly. - **LINE_TEXTURE_STRETCH** = **2** --- Stretches the texture across the line. :ref:`CanvasItem.texture_repeat` of the ``Line2D`` node must be :ref:`CanvasItem.TEXTURE_REPEAT_DISABLED` for best results. Property Descriptions --------------------- .. _class_Line2D_property_antialiased: - :ref:`bool` **antialiased** +-----------+------------------------+ | *Default* | ``false`` | +-----------+------------------------+ | *Setter* | set_antialiased(value) | +-----------+------------------------+ | *Getter* | get_antialiased() | +-----------+------------------------+ If ``true``, the line's border will be anti-aliased. \ **Note:** Line2D is not accelerated by batching when being anti-aliased. ---- .. _class_Line2D_property_begin_cap_mode: - :ref:`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 :ref:`LineCapMode` constants. ---- .. _class_Line2D_property_default_color: - :ref:`Color` **default_color** +-----------+--------------------------+ | *Default* | ``Color(1, 1, 1, 1)`` | +-----------+--------------------------+ | *Setter* | set_default_color(value) | +-----------+--------------------------+ | *Getter* | get_default_color() | +-----------+--------------------------+ The line's color. Will not be used if a gradient is set. ---- .. _class_Line2D_property_end_cap_mode: - :ref:`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 :ref:`LineCapMode` constants. ---- .. _class_Line2D_property_gradient: - :ref:`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. ---- .. _class_Line2D_property_joint_mode: - :ref:`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. ---- .. _class_Line2D_property_points: - :ref:`PackedVector2Array` **points** +-----------+--------------------------+ | *Default* | ``PackedVector2Array()`` | +-----------+--------------------------+ | *Setter* | set_points(value) | +-----------+--------------------------+ | *Getter* | get_points() | +-----------+--------------------------+ The points that form the lines. The line is drawn between every point set in this array. Points are interpreted as local vectors. ---- .. _class_Line2D_property_round_precision: - :ref:`int` **round_precision** +-----------+----------------------------+ | *Default* | ``8`` | +-----------+----------------------------+ | *Setter* | set_round_precision(value) | +-----------+----------------------------+ | *Getter* | get_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 :ref:`width`. For thin lines, this value should be reduced to a number between ``2`` and ``4`` to improve performance. ---- .. _class_Line2D_property_sharp_limit: - :ref:`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 :ref:`joint_mode` is set to :ref:`LINE_JOINT_SHARP`. ---- .. _class_Line2D_property_texture: - :ref:`Texture2D` **texture** +----------+--------------------+ | *Setter* | set_texture(value) | +----------+--------------------+ | *Getter* | get_texture() | +----------+--------------------+ The texture used for the line's texture. Uses ``texture_mode`` for drawing style. ---- .. _class_Line2D_property_texture_mode: - :ref:`LineTextureMode` **texture_mode** +-----------+-------------------------+ | *Default* | ``0`` | +-----------+-------------------------+ | *Setter* | set_texture_mode(value) | +-----------+-------------------------+ | *Getter* | get_texture_mode() | +-----------+-------------------------+ The style to render the ``texture`` on the line. Use :ref:`LineTextureMode` constants. ---- .. _class_Line2D_property_width: - :ref:`float` **width** +-----------+------------------+ | *Default* | ``10.0`` | +-----------+------------------+ | *Setter* | set_width(value) | +-----------+------------------+ | *Getter* | get_width() | +-----------+------------------+ The line's width. ---- .. _class_Line2D_property_width_curve: - :ref:`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 ------------------- .. _class_Line2D_method_add_point: - void **add_point** **(** :ref:`Vector2` position, :ref:`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. ---- .. _class_Line2D_method_clear_points: - void **clear_points** **(** **)** Removes all points from the line. ---- .. _class_Line2D_method_get_point_count: - :ref:`int` **get_point_count** **(** **)** |const| Returns the Line2D's amount of points. ---- .. _class_Line2D_method_get_point_position: - :ref:`Vector2` **get_point_position** **(** :ref:`int` i **)** |const| Returns point ``i``'s position. ---- .. _class_Line2D_method_remove_point: - void **remove_point** **(** :ref:`int` i **)** Removes the point at index ``i`` from the line. ---- .. _class_Line2D_method_set_point_position: - void **set_point_position** **(** :ref:`int` i, :ref:`Vector2` position **)** Overwrites the position in point ``i`` with the supplied ``position``. .. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)` .. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)` .. |vararg| replace:: :abbr:`vararg (This method accepts any number of arguments after the ones described here.)` .. |constructor| replace:: :abbr:`constructor (This method is used to construct a type.)` .. |static| replace:: :abbr:`static (This method doesn't need an instance to be called, so it can be called directly using the class name.)` .. |operator| replace:: :abbr:`operator (This method describes a valid operator to use with this type as left-hand operand.)`
