<description>
|
|
Base class of anything 2D. Canvas items are laid out in a tree; children inherit and extend their parent's transform. [CanvasItem] is extended by [Control] for anything GUI-related, and by [Node2D] for anything related to the 2D engine.
|
|
Any [CanvasItem] can draw. For this, [method update] is called by the engine, then [constant NOTIFICATION_DRAW] will be received on idle time to request redraw. Because of this, canvas items don't need to be redrawn on every frame, improving the performance significantly. Several functions for drawing on the [CanvasItem] are provided (see [code]draw_*[/code] functions). However, they can only be used inside [method _draw], its corresponding [method Object._notification] or methods connected to the [signal draw] signal.
|
|
Canvas items are drawn in tree order. By default, children are on top of their parents so a root [CanvasItem] will be drawn behind everything. This behavior can be changed on a per-item basis.
|
|
A [CanvasItem] can also be hidden, which will also hide its children. It provides many ways to change parameters such as modulation (for itself and its children) and self modulation (only for itself), as well as its blend mode.
|
|
Ultimately, a transform notification can be requested, which will notify the node that its global position changed in case the parent tree changed.
|
|
[b]Note:[/b] Unless otherwise specified, all methods that have angle parameters must have angles specified as [i]radians[/i]. To convert degrees to radians, use [method @GDScript.deg2rad].

Draws a unfilled arc between the given angles. The larger the value of [code]point_count[/code], the smoother the curve. See also [method draw_circle].
|
|
[b]Note:[/b] Line drawing is not accelerated by batching if [code]antialiased[/code] is [code]true[/code].
|
|
[b]Note:[/b] 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 [url=https://github.com/godot-extended-libraries/godot-antialiased-line2d]Antialiased Line2D[/url] add-on then create an AntialiasedRegularPolygon2D node. That node relies on a texture with custom mipmaps to perform antialiasing. 2D batching is also still supported with those antialiased lines.

|
|
<description>
|
|
Returns [code]true[/code] if the node is present in the [SceneTree], its [member visible] property is [code]true[/code] and all its antecedents are also visible. If any antecedent is hidden, this node will not be visible in the scene tree, and is consequently not drawn (see [method _draw]).

<description>
|
|
If [code]enable[/code] is [code]true[/code], this [CanvasItem] will [i]not[/i] inherit its transform from parent [CanvasItem]s. Its draw order will also be changed to make it draw on top of other [CanvasItem]s that are not set as top-level. The [CanvasItem] will effectively act as if it was placed as a child of a bare [Node]. See also [method is_set_as_toplevel].

<method name="show">

|
|
<description>
|
|
Show the [CanvasItem] if it's currently hidden. This is equivalent to setting [member visible] to [code]true[/code]. For controls that inherit [Popup], the correct way to make them visible is to call one of the multiple [code]popup*()[/code] functions instead.

<method name="update">

<description>
|
|
Queues the [CanvasItem] to redraw. During idle time, if [CanvasItem] is visible, [constant NOTIFICATION_DRAW] is sent and [method _draw] is called. This only occurs [b]once[/b] per frame, even if this method has been called multiple times.
