我整晚都在寻找/寻找指南，试图找到如何平滑我的多图像动画。我尝试了一些指南，找到了我喜欢的一个，但它很不稳定。

atm 我的动画有效但闪烁。

我的动画课：

package graphics;

导入 java.awt.Image；导入 java.util.ArrayList；

公共类动画{

private ArrayList<OneScene> scenes;
private int sceneIndex;
private long movieTime;
private long totalTime;

//Constructor
public Animation() {
    scenes = new ArrayList<OneScene>();
    totalTime = 0;
    start();
}

//Add scene to ArayList & set time for each scene
public synchronized void addScene(Image i, long t) {
    totalTime += t;
    scenes.add(new OneScene(i, totalTime));
}

//Start animation
public synchronized void start() {
    movieTime = 0;
    sceneIndex = 0;
}

//Change Scenes
public synchronized void update(long timePassed) {
    if (scenes.size() > 1) {
        movieTime += timePassed;
        if (movieTime >= totalTime) {
            movieTime = 0;
            sceneIndex = 0;
        }
        while(movieTime > getScene(sceneIndex).endTime) {
            sceneIndex++;
        }
    }
}

//Get animation (Image) current scene
public synchronized Image getImage() {
    if (scenes.size() ==0) {
        return null;
    }else{
        return getScene(sceneIndex).pic;
    }
}

//Get Scene
private OneScene getScene(int x) {
    return (OneScene)scenes.get(x);
}

//Private Class
public class OneScene {
    Image pic;
    long endTime;

    public OneScene(Image pic, long endTime) {
        this.pic = pic;
        this.endTime = endTime;
    }
}

&我的一些方法：

Image load1 = new ImageIcon(""+cachemainDir+"1.png").getImage();
    Image load2 = new ImageIcon(""+cachemainDir+"2.png").getImage();
    Image load3 = new ImageIcon(""+cachemainDir+"3.png").getImage();
    Image load4 = new ImageIcon(""+cachemainDir+"4.png").getImage();
    Image load5 = new ImageIcon(""+cachemainDir+"5.png").getImage();
    Image load6 = new ImageIcon(""+cachemainDir+"6.png").getImage();
    Image load7 = new ImageIcon(""+cachemainDir+"7.png").getImage();
    Image load8 = new ImageIcon(""+cachemainDir+"8.png").getImage();
    Image load9 = new ImageIcon(""+cachemainDir+"9").getImage();
    Image load10 = new ImageIcon(""+cachemainDir+"10.png").getImage();
    Image load11 = new ImageIcon(""+cachemainDir+"11.png").getImage();
    Image load12 = new ImageIcon(""+cachemainDir+"12.png").getImage();
    Anim = new Animation();
    Anim.addScene(load1, 100);
    Anim.addScene(load2, 100);
    Anim.addScene(load3, 100);
    Anim.addScene(load4, 100);
    Anim.addScene(load5, 100);
    Anim.addScene(load6, 100);
    Anim.addScene(load7, 100);
    Anim.addScene(load8, 100);
    Anim.addScene(load9, 100);
    Anim.addScene(load10, 100);
    Anim.addScene(load11, 100);
    Anim.addScene(load12, 100);

和...

        while (AppLoading) {
        long timePassed = System.currentTimeMillis() - cumTime;
        cumTime += timePassed;
        Anim.update(timePassed);

        Graphics g = getGraphics();
        draw(g);
        g.dispose();

        try{
            Thread.sleep(0);
        }catch(Exception ex){}
    }

最后....

    public void draw(Graphics g) {
    new BufferedImage(getWidth(), getHeight(), BufferedImage.TYPE_INT_RGB);
    g.drawImage(bg, 0, 0, getWidth(), getHeight(), null);
    g.drawImage(Anim.getImage(), 300, 300, null);
}

你说的闪退是什么意思？实际帧之间是否有空白帧？（您可以通过制作一些静止图像并为其设置动画来测试这一点。）可能是您正在更新到小帧，因为您只有 12 个。如果图像在运行时之外正确动画，这很好。使“cachemainDir”图像在动画中更接近。如果您可能会有所帮助Thread.sleep(5); //or a number besides 0
