layer.states.animationOptions < object>

Set the animation options for the state machine. By default, the global animation options will be used.
译：设置状态的动画选项。默认情况下，将使用全局动画选项。

layerA = new Layer

layerA.states.add
    stateA:
        x: 500
        opacity: 0.5

    stateB:
        x: 200
        opacity: 1

layerA.states.animationOptions =
    curve: "spring(100, 10, 0)"

layerA.states.switch("stateA")

These animation options will now be used for all state switches. To set different animation options for individual states, you can include them directly within the switch statement.
译：这些动画选项现在将被用于所有状态开关。要为单个状态设置不同的动画选项，可以直接在“开关”语句中包含它们。

# Switch to stateB with a spring curve 
layerA.states.switch("stateB", curve: "spring(400, 30, 0)")

# Switch to stateB with an easing curve 
layerA.states.switch("stateB", time: 1, curve: "ease")
