谁能帮我在这个图像流组件中添加一个左右按钮？目前它使用图像来左右导航，但我似乎可以理解如何将按钮与动作脚本链接？我不做太多的闪光工作，所以非常感谢任何帮助。

在舞台上添加两个按钮。

给他们btn1和btn2（或您选择的任何名称）的实例名称

添加以下代码

btn1.onPress = function () {
    flow.title.text="";
    if (ActivePicture==xml.firstChild.childNodes.length-1){
        ActivePicture=0;
    }else{
        ActivePicture++;
    }
}

btn2.onPress = function () {
    flow.title.text="";
    if (ActivePicture<=0){
        ActivePicture=xml.firstChild.childNodes.length-1;
    }else{
        ActivePicture--;
    }

}

发生了什么

您的按钮ActivePicture每次递增或递减 1。如果ActivePicture超过图片数量，它将更改为第一张图片。如果ActivePicture低于图片数量，则转到最后一张图片。
