CanvasLayer

Inherits: Node < Object

Inherited By: ParallaxBackground

Canvas drawing layer.

Description

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).

Property Descriptions

Node custom_viewport

Setter	set_custom_viewport(value)
Getter	get_custom_viewport()

The custom Viewport node assigned to the CanvasLayer. If null, uses the default viewport instead.

bool follow_viewport_enable

Default	false
Setter	set_follow_viewport(value)
Getter	is_following_viewport()

Sets the layer to follow the viewport in order to simulate a pseudo 3D effect.

float follow_viewport_scale

Default	1.0
Setter	set_follow_viewport_scale(value)
Getter	get_follow_viewport_scale()

Scales the layer when using follow_viewport_enable. Layers moving into the foreground should have increasing scales, while layers moving into the background should have decreasing scales.

int layer

Default	1
Setter	set_layer(value)
Getter	get_layer()

Layer index for draw order. Lower values are drawn first.

Vector2 offset

Default	Vector2( 0, 0 )
Setter	set_offset(value)
Getter	get_offset()

The layer's base offset.

float rotation

Default	0.0
Setter	set_rotation(value)
Getter	get_rotation()

The layer's rotation in radians.

float rotation_degrees

Default	0.0
Setter	set_rotation_degrees(value)
Getter	get_rotation_degrees()

The layer's rotation in degrees.

Vector2 scale

Default	Vector2( 1, 1 )
Setter	set_scale(value)
Getter	get_scale()

The layer's scale.

Transform2D transform

Default	Transform2D( 1, 0, 0, 1, 0, 0 )
Setter	set_transform(value)
Getter	get_transform()

The layer's transform.

Method Descriptions

RID get_canvas ( ) const

Returns the RID of the canvas used by this layer.
