Properties

aboveComponents ↔ bool
When true this component render above all components in game.
getter/setter pairinherited
aboveComponentsLevel ↔ int
getter/setter pairinherited
absoluteAngle → double
The resulting angle after all the ancestors and the components own angle has been applied.
no setterinherited
absoluteCenter → Vector2
The absolute center of the component.
no setterinherited
absolutePosition → Vector2
The anchor's position in absolute (world) coordinates.
no setterinherited
absoluteScale → Vector2
The resulting scale after all the ancestors and the components own scale has been applied.
no setterinherited
absoluteScaledSize → Vector2
The resulting size after all the ancestors and the components own scale has been applied.
no setterinherited
absoluteTopLeftPosition → Vector2
The absolute top left position regardless of whether it is a child or not.
no setterinherited
anchor ↔ Anchor
Anchor point for this component. An anchor point describes a point within the rectangle of size size. This point is considered to be the logical "center" of the component. This can be visualized as the point where Flame "grabs" the component. All transforms occur around this point: the position is where the anchor point will end up after the component is translated; the rotation and scaling also happen around this anchor point.
getter/setter pairinherited
angle ↔ double
Rotation angle (in radians) of the component. The component will be rotated around its anchor point in the clockwise direction if the angle is positive, or counterclockwise if the angle is negative.
getter/setter pairinherited
center ↔ Vector2
The position of the center of the component's bounding rectangle in the parent's coordinates.
getter/setter pairinherited
children → ComponentSet
The children of the current component.
no setterinherited
context → BuildContext
Get BuildContext
no setterinherited
debugColor ↔ Color
The color that the debug output should be rendered with.
getter/setter pairinherited
debugCoordinatesPrecision → int?
How many decimal digits to print when displaying coordinates in the debug mode. Setting this to null will suppress all coordinates from the output.
no setterinherited
debugMode ↔ bool
Returns whether this Component is in debug mode or not. When a child is added to the Component it gets the same debugMode as its parent has when it is prepared.
getter/setter pairinherited
debugPaint → Paint
The debugColor represented as a Paint object.
no setterinherited
debugTextPaint → TextPaint
Returns a TextPaint object with the debugColor set as color for the text.
no setterinherited
gameRef ↔ BonfireGameInterface
getter/setter pairinherited
hasChildren → bool
no setterinherited
hasGameRef → bool
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
hasPendingLifecycleEvents → bool
no setterinherited
height ↔ double
The height of the component in local coordinates. Note that the object may visually appear larger or smaller due to application of scale.
getter/setter pairinherited
isFlipHorizontal ↔ bool
Use to do horizontal flip in de render.
getter/setter pairinherited
isFlipVertical ↔ bool
Use to do vertical flip in de render.
getter/setter pairinherited
isLoaded → bool
Whether this component has completed its onLoad step.
no setterinherited
isMounted → bool
Whether this component is currently added to a component tree.
no setterinherited
isVisible ↔ bool
Param checks if this component is visible on the screen
getter/setter pairinherited
lifecycle → _LifecycleManager
no setterinherited
loaded → Future<void>
A future that will complete once this component has finished loading.
no setterinherited
mounted → Future<void>
A future that will complete once the component is mounted on its parent
no setterinherited
opacity ↔ double
Use to set opacity in render Range 0.0..1.0
getter/setter pairinherited
parent → Component?
The current parent of the component, or null if there is none.
no setterinherited
position ↔ NotifyingVector2
The position of this component's anchor on the screen.
getter/setter pairinherited
positionType ↔ PositionType
What coordinate system this component should respect (i.e. should it observe camera, viewport, or use the raw canvas).
getter/setter pairinherited
priority ↔ int
Render priority of this component. This allows you to control the order in which your components are rendered.
getter/setter pairinherited
properties ↔ Map<String, dynamic>?
getter/setter pairinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
scale ↔ NotifyingVector2
The scale factor of this component. The scale can be different along the X and Y dimensions. A scale greater than 1 makes the component bigger, and less than 1 smaller. The scale can also be negative, which results in a mirror reflection along the corresponding axis.
getter/setter pairinherited
scaledSize → Vector2
The "physical" size of the component. This is the size of the component as seen from the parent's perspective, and it is equal to size * scale. This is a computed property and cannot be modified by the user.
no setterinherited
shouldRemove ↔ bool
Whether this component should be removed or not.
getter/setter pairinherited
size ↔ NotifyingVector2
The logical size of the component. The game assumes that this is the approximate size of the object that will be drawn on the screen. This size will therefore be used for collision detection and tap handling.
getter/setter pairinherited
sprite ↔ Sprite?
getter/setter pair
topLeftPosition ↔ Vector2
The top-left corner's position in the parent's coordinates.
getter/setter pairinherited
transform → Transform2D
finalinherited
transformMatrix → Matrix4
The total transformation matrix for the component. This matrix combines translation, rotation and scale transforms into a single entity. The matrix is cached and gets recalculated only as necessary.
no setterinherited
width ↔ double
The width of the component in local coordinates. Note that the object may visually appear larger or smaller due to application of scale.
getter/setter pairinherited
x ↔ double
X position of this component's anchor on the screen.
getter/setter pairinherited
y ↔ double
Y position of this component's anchor on the screen.
getter/setter pairinherited

absolutePositionOf(Vector2 point) → Vector2
Convert local coordinates of a point point inside the component into the global (world) coordinate space.

absolutePositionOfAnchor(Anchor anchor) → Vector2
Similar to absolutePositionOf(), but applies to any anchor point within the component.
inherited
absoluteToLocal(Vector2 point) → Vector2
Transform point from the global (world) coordinate space into the local coordinates. This function is the inverse of absolutePositionOf().

inherited
changeParent(Component newParent) → void
Changes the current parent for another parent and prepares the tree under the new root.
inherited
changePriorityWithoutResorting(int priority) → void
