Framer / Coffescript条件不按预期工作

Question

遵循Framer研讨会示例逐字逐句并且由于某种原因无法获得有条件的声明。

此代码按预期运行

layerA = new Layer
    backgroundColor: "#fff"
    borderRadius: 4
    width: 200
    height: 200
    rotation: 0


layerA.center()

layerA.states.add
  grow:
    scale: 1.5
    rotation: 90

shrink:
    scale: 1
    rotation: 0

layerA.states.animationOptions =
  curve: "spring(400, 50, 30)"

layerA.onClick ->
    layerA.states.next("grow", "shrink")

但是，如果我在下面添加条件，它会被忽略？

    if layerA.states.current is "grow"
        layerA.states.animationOptions = 
        curve: "ease"
        time: 2
    else 
        layerA.states.animationOptions =
        curve: "spring(400,50,30)"
