我想在改变状态时有一个过渡动画。

经过几次尝试,我不明白这是什么问题。我的第一个目标是在隐藏“Card HOME”时触发从 1 到 0 的 alpha 效果

由于没有showEffecthideEffect,我尝试使用transitions属性

更新:查看SDK源,我想我需要添加StatesWithTransitionsImpl,所以我更新了我的代码,但是当点击“描述”时,“家庭卡”没有过渡,它会淡出,但不起作用)

        </js:View>        
    </js:initialView>    
</js:Application>

如何做到这一点?

更新 2:我已经使用 Royale Store 示例的一部分更新了代码。单击“主页”时它正在工作,但奇怪的是,当单击“产品”时却没有。Bug与否?)

我发现要工作,您必须包含 main.css :

@namespace basic "library://ns.apache.org/royale/basic";

global {
    IStatesImpl:            ClassReference("org.apache.royale.core.StatesWithTransitionsImpl");
    IEffectTimer:           ClassReference("org.apache.royale.utils.EffectTimer");
}

另一个问题是,如果我尝试像这样添加珠子:

 <js:beads>
       <core:StatesWithTransitionsImpl/>
       <utils:EffectTimer/>
 </js:beads>

(并删除包括main.css)然后它不工作......

问候

Checkout examples/royale/RoyaleStore. It is using state transitions.
