|
|
A 2D polyline that can optionally be textured.
|
|
</brief_description>
|
|
<description>
|
|
This node draws a 2D polyline, i.e. a shape consisting of several points connected by segments. [Line2D] is not a mathematical polyline, i.e. the segments are not infinitely thin. It is intended for rendering and it can be colored and optionally textured.
|
|
[b]Warning:[/b] Certain configurations may be impossible to draw nicely, such as very sharp angles. In these situations, the node uses fallback drawing logic to look decent.
|
|
[b]Note:[/b] [Line2D] is drawn using a 2D mesh.

Adds a point with the specified [param position] relative to the polyline's own position. If no [param index] is provided, the new point will be added to the end of the points array.
|
|
If [param index] is given, the new point is inserted before the existing point identified by index [param index]. The indices of the points after the new point get increased by 1. The provided [param index] must not exceed the number of existing points in the polyline. See [method get_point_count].

<member name="antialiased" type="bool" setter="set_antialiased" getter="get_antialiased" default="false">
|
|
If [code]true[/code], the polyline's border will be anti-aliased.
|
|
[b]Note:[/b] [Line2D] is not accelerated by batching when being anti-aliased.
|
|
</member>
|
|
<member name="begin_cap_mode" type="int" setter="set_begin_cap_mode" getter="get_begin_cap_mode" enum="Line2D.LineCapMode" default="0">
|
|
The style of the beginning of the polyline, if [member closed] is [code]false[/code]. Use [enum LineCapMode] constants.
|
|
</member>
|
|
<member name="closed" type="bool" setter="set_closed" getter="is_closed" default="false">
|
|
If [code]true[/code] and the polyline has more than 2 points, the last point and the first one will be connected by a segment.
|
|
[b]Note:[/b] The shape of the closing segment is not guaranteed to be seamless if a [member width_curve] is provided.
|
|
[b]Note:[/b] The joint between the closing segment and the first segment is drawn first and it samples the [member gradient] and the [member width_curve] at the beginning. This is an implementation detail that might change in a future version.
|
|
</member>
|
|
<member name="default_color" type="Color" setter="set_default_color" getter="get_default_color" default="Color(1, 1, 1, 1)">
|
|
The color of the polyline. Will not be used if a gradient is set.
|
|
</member>
|
|
<member name="end_cap_mode" type="int" setter="set_end_cap_mode" getter="get_end_cap_mode" enum="Line2D.LineCapMode" default="0">
|
|
The style of the end of the polyline, if [member closed] is [code]false[/code]. Use [enum LineCapMode] constants.
|
|
</member>
|
|
<member name="gradient" type="Gradient" setter="set_gradient" getter="get_gradient">
|
|
The gradient is drawn through the whole line from start to finish. The [member default_color] will not be used if this property is set.
|
|
</member>
|
|
<member name="joint_mode" type="int" setter="set_joint_mode" getter="get_joint_mode" enum="Line2D.LineJointMode" default="0">
|

The style of the connections between segments of the polyline. Use [enum LineJointMode] constants.
|
|
</member>
|
|
<member name="points" type="PackedVector2Array" setter="set_points" getter="get_points" default="PackedVector2Array()">
|
|
The points of the polyline, interpreted in local 2D coordinates. Segments are drawn between the adjacent points in this array.
|
|
</member>
|
|
<member name="round_precision" type="int" setter="set_round_precision" getter="get_round_precision" default="8">
|
|
The smoothness used for rounded joints and caps. Higher values result in smoother corners, but are more demanding to render and update.
|
|
</member>
|
|
<member name="sharp_limit" type="float" setter="set_sharp_limit" getter="get_sharp_limit" default="2.0">
|
|
Determines the miter limit of the polyline. Normally, when [member joint_mode] is set to [constant LINE_JOINT_SHARP], sharp angles fall back to using the logic of [constant LINE_JOINT_BEVEL] joints to prevent very long miters. Higher values of this property mean that the fallback to a bevel joint will happen at sharper angles.
|
|
</member>
|
|
<member name="texture" type="Texture2D" setter="set_texture" getter="get_texture">
|
|
The texture used for the polyline. Uses [member texture_mode] for drawing style.

</member>
|
|
<member name="texture_mode" type="int" setter="set_texture_mode" getter="get_texture_mode" enum="Line2D.LineTextureMode" default="0">

<member name="width" type="float" setter="set_width" getter="get_width" default="10.0">
|
|

</member>
|
|
<member name="width_curve" type="Curve" setter="set_curve" getter="get_curve">
|
|
The polyline's width curve. The width of the polyline over its length will be equivalent to the value of the width curve over its domain. The width curve should be a unit [Curve].

|
|
<constants>
|
|
<constant name="LINE_JOINT_SHARP" value="0" enum="LineJointMode">
|
|
Makes the polyline's joints pointy, connecting the sides of the two segments by extending them until they intersect. If the rotation of a joint is too big (based on [member sharp_limit]), the joint falls back to [constant LINE_JOINT_BEVEL] to prevent very long miters.
|
|
</constant>
|
|
<constant name="LINE_JOINT_BEVEL" value="1" enum="LineJointMode">
|
|
Makes the polyline's joints bevelled/chamfered, connecting the sides of the two segments with a simple line.
|
|
</constant>
|
|
<constant name="LINE_JOINT_ROUND" value="2" enum="LineJointMode">
|
|
Makes the polyline's joints rounded, connecting the sides of the two segments with an arc. The detail of this arc depends on [member round_precision].
|
|
</constant>
|
|
<constant name="LINE_CAP_NONE" value="0" enum="LineCapMode">
|
|
Draws no line cap.
|
|
</constant>
|
|
<constant name="LINE_CAP_BOX" value="1" enum="LineCapMode">
|
|
Draws the line cap as a box, slightly extending the first/last segment.
|
|
</constant>
|
|
<constant name="LINE_CAP_ROUND" value="2" enum="LineCapMode">
|
|
Draws the line cap as a semicircle attached to the first/last segment.
|
|
</constant>
|
|
<constant name="LINE_TEXTURE_NONE" value="0" enum="LineTextureMode">
|
|
Takes the left pixels of the texture and renders them over the whole polyline.
|
|
</constant>
|
|
<constant name="LINE_TEXTURE_TILE" value="1" enum="LineTextureMode">
|
|
Tiles the texture over the polyline. [member CanvasItem.texture_repeat] of the [Line2D] node must be [constant CanvasItem.TEXTURE_REPEAT_ENABLED] or [constant CanvasItem.TEXTURE_REPEAT_MIRROR] for it to work properly.
|
|
</constant>
|
|
<constant name="LINE_TEXTURE_STRETCH" value="2" enum="LineTextureMode">
|
|
Stretches the texture across the polyline. [member CanvasItem.texture_repeat] of the [Line2D] node must be [constant CanvasItem.TEXTURE_REPEAT_DISABLED] for best results.
