Question

我只需要知道如何在它上面的数组的newImage.source = "asset/%myArray%";行设置其源代码。我确信有一个简单的解决方案。我只是不确定如何在Google上提出这个问题......

                //makes new image
                var newImage:Image = new Image();

                //sets the image source for each image
                newImage.source = "asset/%myArray%";

                //adds the image to the stage
                grpMovies.addElement(newImage);

Answer 1

假设您的图片位于asset/，请尝试：

newImage.source = "asset/" + arrayEntry;

Answer 2

将for循环中的代码修改为：

newImage.source = "asset\\" + myArray[i];

使用包含路径的Strings时，最好使用\\符号。

如何在AS3中设置字符串数组的图像源？
