|
Adds a point with the specified [param position] relative to the line's own position. Appends the new point at the end of the point list.
|
|
If [param index] is given, the new point is inserted before the existing point identified by index [param index]. Every existing point starting from [param index] is shifted further down the list of points. The index must be greater than or equal to [code]0[/code] and must not exceed the number of existing points in the line. See [method get_point_count].

<member name="gradient" type="Gradient" setter="set_gradient" 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.

|
|
<member name="points" type="PackedVector2Array" setter="set_points" getter="get_points" default="PackedVector2Array()">
|
|
The points that form the lines. The line is drawn between every point set in this array. Points are interpreted as local vectors.
|
|
</member>
|
|
<member name="round_precision" type="int" setter="set_round_precision" getter="get_round_precision" default="8">
|
|
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.
|
|
[b]Note:[/b] The default value is tuned for lines with the default [member width]. For thin lines, this value should be reduced to a number between [code]2[/code] and [code]4[/code] to improve performance.
|
|
</member>
|
|
<member name="sharp_limit" type="float" setter="set_sharp_limit" getter="get_sharp_limit" default="2.0">
|
|
The direction difference in radians between vector points. This value is only used if [member joint_mode] is set to [constant LINE_JOINT_SHARP].
|
|
</member>
|
|
<member name="texture" type="Texture2D" setter="set_texture" getter="get_texture">
|

|
|
<constants>
|
|
<constant name="LINE_JOINT_SHARP" value="0" enum="LineJointMode">
|
|
The line's joints will be pointy. If [code]sharp_limit[/code] is greater than the rotation of a joint, it becomes a bevel joint instead.
|
|
</constant>
|
|
<constant name="LINE_JOINT_BEVEL" value="1" enum="LineJointMode">
|
|
The line's joints will be bevelled/chamfered.

|
<constant name="LINE_JOINT_ROUND" value="2" enum="LineJointMode">
|
|
The line's joints will be rounded.

|
<constant name="LINE_CAP_NONE" value="0" enum="LineCapMode">
|
|
Don't draw a line cap.

</constant>
|
|
<constant name="LINE_TEXTURE_TILE" value="1" enum="LineTextureMode">
|
|
Tiles the texture over the line. [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 line. [member CanvasItem.texture_repeat] of the [Line2D] node must be [constant CanvasItem.TEXTURE_REPEAT_DISABLED] for best results.
