  • Sets the initial velocity of the object attached to the spring.

    Declaration

    Swift

    @discardableResult
public func springVelocity(_ velocity: Float) -> Self

    Parameters

    velocity

    The initial velocity of the object attached to the spring.

    Return Value

    Self

  • Sets the velocitys of the object attached to the spring.

    Declaration

    Swift

    public func springVelocity(_ velocity: Array<Float>) -> Self

    Parameters

    velocity

    The velocitys of the object attached to the spring.

    Return Value

    Self

  • Sets the bounce of the object attached to the spring. Together with the springSpeed ​​value, can change the animation effect. The larger the value, the larger the spring motion range, and the greater the vibration and elasticity. Defined as a value in the range of [0,20]. Default is 4.

    Declaration

    Swift

    @discardableResult
public func springBounciness(_ bounce: Float) -> Self

    Parameters

    bounce

    The bounce of the object attached to the spring.

    Return Value

    Self

  • Sets the speed of the object attached to the spring. Together with the springBounciness value, can change the animation effect. A higher value increases the damping capacity of the spring, resulting in a faster initial speed and faster rebound deceleration. Defined as a value in the range of [0,20] . Default is 12.

    Declaration

    Swift

    @discardableResult
public func springSpeed(_ speed: Float) -> Self

    Parameters

    speed

    The speed of the object attached to the spring.

    Return Value

    Self

  • Set the tension of the object attached to the spring. Dynamic tension can be used on elasticity and speed to fine-tune the animation effect.

    Declaration

    Swift

    @discardableResult
public func springTension(_ tension: Float) -> Self

    Parameters

    tension

    The tension of the object attached to the spring.

    Return Value

    Self

  • Set the friction of the object attached to the spring. Dynamic friction can be used on elasticity and speed to fine-tune animation effects.

    Declaration

    Swift

    @discardableResult
public func springFriction(_ friction: Float) -> Self

    Parameters

    friction

    The friction of the object attached to the spring.

    Return Value

    Self

  • Set the mass of the object attached to the spring. Dynamic mass can be used on elasticity and speed to fine-tune animation effects.

    Declaration

    Swift

    @discardableResult
public func springMass(_ mass: Float) -> Self

    Parameters

    mass

    The mass of the object attached to the spring.

    Return Value

    Self
