使用JavaFX的ImageView精灵动画

我试图在登录窗口（stage）中创建一个sprite动画，使用JavaFX在用户获得登录和密码信息后播放。我试图使用Michael Heinrichs在其关于的博客文章中发布的类，但我无法使其工作，主要是因为我不知道如何在ImageView中创建动画，而不使用start方法（在我的情况下也不起作用）

这是我在FXML文件中用于登录阶段的代码：

<GridPane alignment="CENTER" hgap="10.0" vgap="10.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="crud.controller.MainController">
    <padding>
        <Insets bottom="25.0" left="25.0" right="25.0" top="25.0" />
    </padding>
    <children>
        <ImageView fx:id="loginAnimationImageView" GridPane.columnIndex="0" GridPane.halignment="CENTER" GridPane.columnSpan="2" GridPane.rowIndex="0">
            <image>
                <Image url="@../assets/shop-sprite.png" />
            </image>
        <viewport>
            <Rectangle2D height="130.0" width="131.0" />
        </viewport>
        </ImageView>
        <Label text="Usuario" GridPane.columnIndex="0" GridPane.halignment="RIGHT" GridPane.rowIndex="2" />
        <TextField fx:id="loginTextField" onAction="#onEnterTextFieldAction" GridPane.columnIndex="1" GridPane.rowIndex="2" />
        <Label text="Contraseña" GridPane.columnIndex="0" GridPane.rowIndex="3" />
        <PasswordField fx:id="passwordTextField" onAction="#onEnterPasswordFieldAction" GridPane.columnIndex="1" GridPane.rowIndex="3" />
        <Button fx:id="loginButton" onAction="#loginButtonAction" text="Ingresar" GridPane.columnIndex="0" GridPane.columnSpan="2" GridPane.halignment="CENTER" GridPane.rowIndex="5" />
    </children>
</GridPane>

最后，以下是常量声明：

private static final Image IMAGE = new Image("https://i.cloudup.com/1VA2FCnqY6-2000x2000.png");
private static final int COLUMNS  = 4;
private static final int COUNT    = 12;
private static final int OFFSET_X = 0;
private static final int OFFSET_Y = 0;
private static final int WIDTH    = 131;
private static final int HEIGHT   = 125;

这就是登录阶段现在的样子，我想为它制作徽标动画：

你们能帮我理解如何在这个案例中使用图像视图吗

我可以使用ImageView创建这种效果，或者我只是在浪费时间？我做到了，我可以使用JavaFX制作这个简单的动画，如果你想完成类似的事情，我想与你分享

首先，我用这段代码为登录阶段创建了FXML文件（请记住，您必须为控制器类和映像文件设置正确的位置）

就这样，您不需要做任何其他事情就可以为任何JavaFX应用程序创建这个简单的动画。享受吧

看。有两种方法使用与您提到的链接类似的视口，ans using clip.SpriteAnimation使用ImageView setViewport（）来处理不同的精灵，经过一些实验后，我发现使用单独的图像（setImage（））比setViewport具有更好的性能>100%。

private static final Image IMAGE = new Image("https://i.cloudup.com/1VA2FCnqY6-2000x2000.png");
private static final int COLUMNS  = 4;
private static final int COUNT    = 12;
private static final int OFFSET_X = 0;
private static final int OFFSET_Y = 0;
private static final int WIDTH    = 131;
private static final int HEIGHT   = 125;
