Properties

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

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.
