Property Detail

angle

public final javafx.beans.property.DoubleProperty angleProperty

Constructor Detail

RotationComponent

public RotationComponent()

Constructs rotation with angle = 0.

RotationComponent

public RotationComponent(double angle)

Constructs rotation with given angle.

Parameters:

angle - the angle

Method Detail

rotateBy

public final void rotateBy(double byAngle)

Rotate entity view by given angle. Note: this doesn't affect hit boxes. For more accurate collisions use PhysicsComponent.

Parameters:

byAngle - rotation angle in degrees

rotateToVector

public final void rotateToVector(javafx.geometry.Point2D vector)

Set absolute rotation of the entity view to angle between vector and positive X axis. This is useful for projectiles (bullets, arrows, etc) which rotate depending on their current velocity. Note, this assumes that at 0 angle rotation the scene view is facing right.

Parameters:

vector - the rotation vector / velocity vector

angleProperty

public final javafx.beans.property.DoubleProperty angleProperty()

toString

public String toString()

Overrides:

toString in class DoubleComponent

copy

public RotationComponent copy()

Description copied from interface: CopyableComponent

Copies this component. The general contract should be similar to Object.clone(). The 'depth' of the copy should be determined by the user.

Specified by:

copy in interface CopyableComponent<RotationComponent>

Returns:

new instance (copy) of the component with copied values
