Canvas drawing layer. [CanvasItem] nodes that are direct or indirect children of a [CanvasLayer] will be drawn in that layer. The layer is a numeric index that defines the draw order. The default 2D scene renders with index 0, so a [CanvasLayer] with index -1 will be drawn below, and one with index 1 will be drawn above. This is very useful for HUDs (in layer 1+ or above), or backgrounds (in layer -1 or below).
|
|
Embedded [Window]s are placed in layer 1024. CanvasItems in layer 1025 or above appear in front of embedded windows, CanvasItems in layer 1023 or below appear behind embedded windows.

Returns the RID of the canvas used by this layer.

<return type="Transform2D" />
|

<description>
|
|
Returns the transform from the [CanvasLayer]s coordinate system to the [Viewport]s coordinate system.

<method name="hide">
|
|
<return type="void" />
|
|
<description>
|
|
Hides any [CanvasItem] under this [CanvasLayer]. This is equivalent to setting [member visible] to [code]false[/code].

<method name="show">
|
|
<return type="void" />
|
|
<description>
|
|
Shows any [CanvasItem] under this [CanvasLayer]. This is equivalent to setting [member visible] to [code]true[/code].

<members>
|
|
<member name="custom_viewport" type="Node" setter="set_custom_viewport" getter="get_custom_viewport">
|
|
The custom [Viewport] node assigned to the [CanvasLayer]. If [code]null[/code], uses the default viewport instead.
|
|
</member>
|
|
<member name="follow_viewport_enabled" type="bool" setter="set_follow_viewport" getter="is_following_viewport" default="false">
|
|
If enabled, the [CanvasLayer] will use the viewport's transform, so it will move when camera moves instead of being anchored in a fixed position on the screen.
|
|
Together with [member follow_viewport_scale] it can be used for a pseudo 3D effect.
|
|
</member>
|
|
<member name="follow_viewport_scale" type="float" setter="set_follow_viewport_scale" getter="get_follow_viewport_scale" default="1.0">
|
|
Scales the layer when using [member follow_viewport_enabled]. Layers moving into the foreground should have increasing scales, while layers moving into the background should have decreasing scales.
|
|
</member>
|
|
<member name="layer" type="int" setter="set_layer" getter="get_layer" default="1">
|
|
Layer index for draw order. Lower values are drawn behind higher values.
|
|
</member>
|
|
<member name="offset" type="Vector2" setter="set_offset" getter="get_offset" default="Vector2(0, 0)">
|
|
The layer's base offset.
|
|
</member>
|
|
<member name="rotation" type="float" setter="set_rotation" getter="get_rotation" default="0.0">
|
|
The layer's rotation in radians.
|
|
</member>
|
|
<member name="scale" type="Vector2" setter="set_scale" getter="get_scale" default="Vector2(1, 1)">
|
|
The layer's scale.
|
|
</member>
|
|
<member name="transform" type="Transform2D" setter="set_transform" getter="get_transform" default="Transform2D(1, 0, 0, 1, 0, 0)">
|
|
The layer's transform.
|
|
</member>
|
|
<member name="visible" type="bool" setter="set_visible" getter="is_visible" default="true">
|
|
If [code]false[/code], any [CanvasItem] under this [CanvasLayer] will be hidden.
|
|
Unlike [member CanvasItem.visible], visibility of a [CanvasLayer] isn't propagated to underlying layers.
