Sprite class

A Sprite is a Node that renders a bitmap image to the screen.

Inheritance
Mixed in types

Constructors

Sprite([SpriteTexture texture])
Creates a new sprite from the provided texture. [...]
Sprite.fromImage(Image image)
Creates a new sprite from the provided image. [...]

Properties

children List<Node>
A list of the children of this node. [...]
read-only, inherited
colorOverlay Color
The color to draw on top of the sprite, null if no color overlay is used. [...]
read / write, inherited
constrainProportions bool
If true, constrains the proportions of the image by scaling it down, if its proportions doesn't match the size. [...]
read / write
constraints List<Constraint>
A List of Constraints that will be applied to the node. The constraints are applied after the update method has been called.

Methods

addChild(Node child) → void
Adds a child to this node. [...]
inherited
applyConstraints(double dt) → void
Called to apply the constraints to the node. Normally, this method is called automatically by the SpriteBox, but it can be called manually if the constraints need to be applied immediately.
inherited
applyTransformForPivot(Canvas canvas) → void
Call this method in your paint method if you want the origin of your drawing to be the top left corner of the node's bounding box. [...]
inherited
computeTransformMatrix() Matrix4
Computes the transformation matrix of this node. This method can be overriden if a custom matrix is required. There is usually no reason to call this method directly.
inherited
convertPointFromNode(Offset point, Node node) Offset
Converts a point from another nodes coordinate system into the local coordinate system of this node. [...]
inherited
convertPointToBoxSpace(Offset nodePoint) Offset
Converts a point from the local coordinate system of the node to the coordinate system of the SpriteBox. [...]
inherited
convertPointToNodeSpace(Offset boxPoint) Offset
Converts a point from the coordinate system of the SpriteBox to the local coordinate system of the node. [...]
inherited
handleEvent(SpriteBoxEvent event) bool
Handles an event, such as a pointer (touch or mouse) event. [...]
inherited
invalidateTransformMatrix() → void
Invalidates the current transform matrix. If the computeTransformMatrix method is overidden, this method should be called whenever a property changes that affects the matrix.
inherited
isPointInside(Offset nodePoint) bool
Returns true if the point is inside the node, the point is in the local coordinate system of the node. [...]
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
paint(Canvas canvas) → void
Paints this node to the canvas. [...]
override
removeAllChildren() → void
Removes all children of this node. [...]
inherited
removeChild(Node child) → void
Removes a child from this node. [...]
inherited
removeFromParent() → void
Removes this node from its parent node. [...]
inherited
spriteBoxPerformedLayout() → void
Called whenever the SpriteBox is modified or resized, or if the device is rotated. [...]
inherited
toString() String
Returns a string representation of this object.
inherited
update(double dt) → void
Called before a frame is drawn. [...]
inherited

Operators

operator ==(dynamic other) bool
The equality operator. [...]
