Instance members

• var clipChildren: CanvasItem.ClipChildrenMode

  Allows the current node to clip children nodes, essentially acting as a mask.

• var draw: SimpleSignal

  Emitted when the CanvasItem must redraw, after the related notificationDraw notification, and before _draw is called.

• var hidden: SimpleSignal

  Emitted when becoming hidden.

• var itemRectChanged: SimpleSignal

  Emitted when the item’s Rect2 boundaries (position or size) have changed, or when an action is taking place that may have impacted these boundaries (e.g. changing texture).

• var lightMask: Int32

  The rendering layers in which this CanvasItem responds to Light2D nodes.

• var material: Material?

  The material applied to this CanvasItem.

• var modulate: Color

  The color applied to this CanvasItem. This property does affect child CanvasItems, unlike selfModulate which only affects the node itself.

• var selfModulate: Color

  The color applied to this CanvasItem. This property does not affect child CanvasItems, unlike modulate which affects both the node itself and its children.

• var showBehindParent: Bool

  If true, the object draws behind its parent.

• var textureFilter: CanvasItem.TextureFilter

  The texture filtering mode to use on this CanvasItem.

• var textureRepeat: CanvasItem.TextureRepeat

  The texture repeating mode to use on this CanvasItem.

• var topLevel: Bool

  If true, this CanvasItem will not inherit its transform from parent CanvasItems. Its draw order will also be changed to make it draw on top of other CanvasItems that do not have topLevel set to true. The CanvasItem will effectively act as if it was placed as a child of a bare Node.

• var useParentMaterial: Bool

  If true, the parent CanvasItem‘s material property is used as this one’s material.

• var visibilityChanged: SimpleSignal

  Emitted when the visibility (hidden/visible) changes.

• var visibilityLayer: UInt32

  The rendering layer in which this CanvasItem is rendered by Viewport nodes. A Viewport will render a CanvasItem if it and all its parents share a layer with the Viewport’s canvas cull mask.

• var visible: Bool

  If true, this CanvasItem is drawn. The node is only visible if all of its ancestors are visible as well (in other words, isVisibleInTree must return true).

• var ySortEnabled: Bool

  If true, child nodes with the lowest Y position are drawn before those with a higher Y position. If false, Y-sorting is disabled. Y-sorting only affects children that inherit from CanvasItem.

• var zAsRelative: Bool

  If true, the node’s Z index is relative to its parent’s Z index. If this node’s Z index is 2 and its parent’s effective Z index is 3, then this node’s effective Z index will be 2 + 3 = 5.

• var zIndex: Int32

  Z index. Controls the order in which the nodes render. A node with a higher Z index will display in front of others. Must be between RenderingServercanvasItemZMin and ``RenderingServer/``canvasItemZMax (inclusive).

• func drawAnimationSlice(animationLength: Double, sliceBegin: Double, sliceEnd: Double, offset: Double)

  Subsequent drawing commands will be ignored unless they fall within the specified animation slice. This is a faster way to implement animations that loop on background rather than redrawing constantly.

• func drawArc(center: Vector2, radius: Double, startAngle: Double, endAngle: Double, pointCount: Int32, color: Color, width: Double, antialiased: Bool)

  Draws an unfilled arc between the given angles with a uniform color and width and optional antialiasing (supported only for positive width). The larger the value of pointCount, the smoother the curve. See also drawCircle(position:radius:color:).

• func drawChar(font: Font?, pos: Vector2, char: String, fontSize: Int32, modulate: Color)

  Draws a string first character using a custom font.

• func drawCharOutline(font: Font?, pos: Vector2, char: String, fontSize: Int32, size: Int32, modulate: Color)

  Draws a string first character outline using a custom font.

• func drawCircle(position: Vector2, radius: Double, color: Color)

  Draws a colored, filled circle. See also drawArc(center:radius:startAngle:endAngle:pointCount:color:width:antialiased:), drawPolyline(points:color:width:antialiased:) and drawPolygon(points:colors:uvs:texture:).

• func drawColoredPolygon(points: PackedVector2Array, color: Color, uvs: PackedVector2Array, texture: Texture2D?)

  Draws a colored polygon of any number of points, convex or concave. Unlike drawPolygon(points:colors:uvs:texture:), a single color must be specified for the whole polygon.

• func drawDashedLine(from: Vector2, to: Vector2, color: Color, width: Double, dash: Double, aligned: Bool)

  Draws a dashed line from a 2D point to another, with a given color and width. See also drawMultiline(points:color:width:) and drawPolyline(points:color:width:antialiased:).

• func drawEndAnimation()

  After submitting all animations slices via drawAnimationSlice(animationLength:sliceBegin:sliceEnd:offset:), this function can be used to revert drawing to its default state (all subsequent drawing commands will be visible). If you don’t care about this particular use case, usage of this function after submitting the slices is not required.

• func drawLcdTextureRectRegion(texture: Texture2D?, rect: Rect2, srcRect: Rect2, modulate: Color)

  Draws a textured rectangle region of the font texture with LCD subpixel anti-aliasing at a given position, optionally modulated by a color.

• func drawMultiline(points: PackedVector2Array, color: Color, width: Double)

  Draws multiple disconnected lines with a uniform width and color. Each line is defined by two consecutive points from points array, i.e. i-th segment consists of points[2 * i], points[2 * i + 1] endpoints. When drawing large amounts of lines, this is faster than using individual drawLine(from:to:color:width:antialiased:) calls. To draw interconnected lines, use drawPolyline(points:color:width:antialiased:) instead.

• func drawMultilineColors(points: PackedVector2Array, colors: PackedColorArray, width: Double)

  Draws multiple disconnected lines with a uniform width and segment-by-segment coloring. Each segment is defined by two consecutive points from points array and a corresponding color from colors array, i.e. i-th segment consists of points[2 * i], points[2 * i + 1] endpoints and has colors_ color. When drawing large amounts of lines, this is faster than using individual drawLine(from:to:color:width:antialiased:) calls. To draw interconnected lines, use drawPolylineColors(points:colors:width:antialiased:) instead.

• func drawMultilineString(font: Font?, pos: Vector2, text: String, alignment: HorizontalAlignment, width: Double, fontSize: Int32, maxLines: Int32, modulate: Color, brkFlags: TextServer.LineBreakFlag, justificationFlags: TextServer.JustificationFlag, direction: TextServer.Direction, orientation: TextServer.Orientation)

  Breaks text to the lines and draws text outline using the specified font at the pos (top-left corner). The text will have its color multiplied by modulate. If width is greater than or equal to 0, the text will be clipped if it exceeds the specified width.

• func drawMultimesh(MultiMesh?, texture: Texture2D?)

  Draws a MultiMesh in 2D with the provided texture. See MultiMeshInstance2D for related documentation.

• func drawPolygon(points: PackedVector2Array, colors: PackedColorArray, uvs: PackedVector2Array, texture: Texture2D?)

  Draws a solid polygon of any number of points, convex or concave. Unlike drawColoredPolygon(points:color:uvs:texture:), each point’s color can be changed individually. See also drawPolyline(points:color:width:antialiased:) and drawPolylineColors(points:colors:width:antialiased:). If you need more flexibility (such as being able to use bones), use canvasItemAddTriangleArray(item:indices:points:colors:uvs:bones:weights:texture:count:) instead.

• func drawPolyline(points: PackedVector2Array, color: Color, width: Double, antialiased: Bool)

  Draws interconnected line segments with a uniform color and width and optional antialiasing (supported only for positive width). When drawing large amounts of lines, this is faster than using individual drawLine(from:to:color:width:antialiased:) calls. To draw disconnected lines, use drawMultiline(points:color:width:) instead. See also drawPolygon(points:colors:uvs:texture:).

• func drawPolylineColors(points: PackedVector2Array, colors: PackedColorArray, width: Double, antialiased: Bool)

  Draws interconnected line segments with a uniform width, point-by-point coloring, and optional antialiasing (supported only for positive width). Colors assigned to line points match by index between points and colors, i.e. each line segment is filled with a gradient between the colors of the endpoints. When drawing large amounts of lines, this is faster than using individual drawLine(from:to:color:width:antialiased:) calls. To draw disconnected lines, use drawMultilineColors(points:colors:width:) instead. See also drawPolygon(points:colors:uvs:texture:).

• func drawPrimitive(points: PackedVector2Array, colors: PackedColorArray, uvs: PackedVector2Array, texture: Texture2D?)

  Draws a custom primitive. 1 point for a point, 2 points for a line, 3 points for a triangle, and 4 points for a quad. If 0 points or more than 4 points are specified, nothing will be drawn and an error message will be printed. See also drawLine(from:to:color:width:antialiased:), drawPolyline(points:color:width:antialiased:), drawPolygon(points:colors:uvs:texture:), and drawRect(_:color:filled:width:).

• func isLocalTransformNotificationEnabled() -> Bool

  Returns true if local transform notifications are communicated to children.

• func isTransformNotificationEnabled() -> Bool

  Returns true if global transform notifications are communicated to children.

• func isVisibleInTree() -> Bool

  Returns true if the node is present in the SceneTree, its visible property is true and all its ancestors are also visible. If any ancestor is hidden, this node will not be visible in the scene tree, and is consequently not drawn (see _draw).

  Assigns screenPoint as this node’s new local transform.

• func makeInputLocal(event: InputEvent?) -> InputEvent?

  Transformations issued by event’s inputs are applied in local space instead of global space.

• func moveToFront()

  Moves this node to display on top of its siblings.

• func queueRedraw()

  Queues the CanvasItem to redraw. During idle time, if CanvasItem is visible, notificationDraw is sent and _draw is called. This only occurs once per frame, even if this method has been called multiple times.

• func setNotifyLocalTransform(enable: Bool)

  If enable is true, this node will receive notificationLocalTransformChanged when its local transform changes.

• func setNotifyTransform(enable: Bool)

  If enable is true, this node will receive notificationTransformChanged when its global transform changes.

• func setVisibilityLayerBit(layer: UInt32, enabled: Bool)

  Set/clear individual bits on the rendering visibility layer. This simplifies editing this CanvasItem’s visibility layer.

• func show()

  Show the CanvasItem if it’s currently hidden. This is equivalent to setting visible to true. For controls that inherit Popup, the correct way to make them visible is to call one of the multiple popup*() functions instead.
