Question

我试图从同一个班级创建多个动画兔子，但我似乎无法绕过它，也许有人可以提供帮助。目前我的场景中只有一个兔子（它跳到右边）

在这里使用此代码：

private void constructRootBunny(boolean preview)
{       
    GameObject bunnyRoot = new GameObject();

        game.RemoveBunnyObject(bunnyRoot);

    bunnyRoot.GetTransform().GetPos().Set(new Vector3f(506+bunny_X,500,506.5+bunny_Z)); 
    bunnyRoot.GetTransform().SetScale(new Vector3f(0.1,0.1,0.1));

    bunny_X += 0.005; // bunny 'hops' to the right

    if(preview == true) {   
            String bunnyFrame = bunny_WalkCycle.get(currentFrame); //obj files

            Mesh mesh = new Mesh(bunnyFrame );
            Material material = new Material (new Texture("bunny_Furr1.png"),
                            new Texture("diffuse_NRM.jpg"),
                            new Texture("diffuse_DISP.jpg"));
            bunnyRoot.AddComponent(new MeshRenderer(mesh, material));
        }

        game.AddBunnyObject(bunnyRoot);

    currentFrame++;

    if(currentFrame== 30) {
        currentFrame= 0; //resets animation
    }
}

我可以很容易地拥有多个兔子，但它们是静态的，我不能让它们动画（甚至不能同时）。我不知道如何将不同的行为模式应用到各自的兔子，这样他们就会最终独立行动（有不同的动画，走到不同的地方等等）..

我可以尝试的任何想法或建议吗？

您已将动画硬编码到代码中。您需要动态分配动画行为。

您可以使用一组预定义的行为并使用Random Number Generator为兔子分配行为来执行此操作。

作为一个想法，考虑创建一个提供抽象方法的Behavior类。然后，可以考虑制作一个JumpBehavior类，其范围为Behavior，并且要求您指定hopFrequency，maximumHeight和movementDirection。然后，您可以使用不同的参数实例化其中几个JumpBehaviors，以创建一系列独特的行为。

将这些行为分配给兔子后，您可以按帧更新兔子。

public abstract class Behavior
{
    public abstract void initBehavior();
    public abstract void updateBunny(GameObject bunny);
}

public class JumpBehavior extends Behavior
{
    private long hopFrequency = 1000; //1 hop / 1000 milliseconds.
    private double maximumHeight = 20, movementVelocity = 0;

    public JumpBehavior(long hopFrequency, double maximumHeight, double movementVelocity)
    {
        this.hopFrequency = hopFrequency;
        this.maximumHeight = maximumHeight;
        this.movementVelocity = movementVelocity;
    }

    private long previousTimeMillis = 0;
    private long elapsedTimeMillis = 0;
    private long timeSinceHop = 0;

    public void initBehavior()
    {
        //Start the clock.
        previousTimeMillis = System.currentTimeMillis();
        elapsedTimeMillis = System.currentTimeMillis();
    }

    public void updateBunny(GameObject bunny)
    {
        //Implement logic to control bunny here.
        //Consider some randomization using a Random Number Generator.

        //Keep track of time.
        elapsedTimeMillis = System.currentTimeMillis() - previousTimeMills;

        //If velocity is negative, then we move left.
        bunny.X += movementVelocity * elapsedTimeMillis;

        timeSinceHop += elapsedTimeMillis;
        if (timeSinceHop >= hopFrequency)
        {
            //Reset counter, but keep the extra milliseconds passed.
            timeSinceHop -= hopFrequency;

            //Apply an acceleration to the bunny to start the hop.
            //Maybe add logic to make sure it doesn't hop while in the air.
            bunny.Velocity.Y += maximumHeight;
        }

        previousTimeMillis = elapsedTimeMillis;
    }
}

Java创建具有独立行为模式的多个动画对象
