NodeWithSize class
The super class of any Node that has a size.
NodeWithSize adds the ability for a node to have a size and a pivot point.
- Inheritance
- Implementers
Constructors
- NodeWithSize(Size size)
- Creates a new NodeWithSize.
Properties
-
children
→ List<
Node> -
A list of the children of this node.
no setterinherited
-
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.
getter/setter pairinherited
- handleMultiplePointers ↔ bool
-
If set to true the node will receive multiple pointers, otherwise it will
only receive events the first pointer.
getter/setter pairinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- inverseTransformMatrix → Matrix4
-
The inverse transform matrix used by this node.
no setterinherited
- motions → MotionController
-
The MotionController associated with this node.
no setterinherited
- parent → Node?
-
The parent of this node, or null if it doesn't have a parent.
no setterinherited
- paused ↔ bool
-
Decides if the node and its children is currently paused.
getter/setter pairinherited
- pivot ↔ Offset
-
The normalized point which the node is transformed around.
getter/setter pair
- position ↔ Offset
-
The position of this node relative to its parent.
getter/setter pairinherited
- rotation ↔ double
-
The rotation of this node in degrees.
getter/setter pairinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- scale ↔ double
-
The scale of this node relative its parent.
getter/setter pairinherited
- scaleX ↔ double
-
The horizontal scale of this node relative its parent.
getter/setter pairinherited
- scaleY ↔ double
-
The vertical scale of this node relative its parent.
getter/setter pairinherited
- size ↔ Size
-
Changing the size will affect the size of the rendering of the node.
getter/setter pair
- skewX ↔ double
-
The skew along the x-axis of this node in degrees.
getter/setter pairinherited
- skewY ↔ double
-
The skew along the y-axis of this node in degrees.
getter/setter pairinherited
- spriteBox → SpriteBox?
-
The SpriteBox this node is added to, or null if it's not currently
added to a SpriteBox.
no setterinherited
- transformMatrix → Matrix4
-
The transformMatrix describes the transformation from the node's parent.
no setterinherited
- userInteractionEnabled ↔ bool
-
The node will receive user interactions, such as pointer (touch or mouse)
events.
getter/setter pairinherited
- visible ↔ bool
-
The visibility of this node and its children.
getter/setter pairinherited
- zPosition ↔ double
-
The draw order of this node compared to its parent and its siblings.
getter/setter pairinherited
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.
-
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 anothernode
s 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
-
handleKeyboardEvent(
KeyEvent event) → bool -
Handles a keyboard 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 point) → bool -
Returns true if the
point
is inside the node, thepoint
is in the local coordinate system of the node.override -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
paint(
Canvas canvas) → void -
Paints this node to the canvas.
inherited
-
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 -
A string representation of this object.
inherited
-
update(
double dt) → void -
Called before a frame is drawn.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
