队列AndEngine多个实体修饰符 [英] Queue multiple entity modifiers in AndEngine

问题描述

我想有一个精灵（指针的）沿着两条路，一前一后。这里是我的code：

I'm trying to have a sprite ("pointer" below) along two paths, one after the other. Here is my code:

    scene.attachChild(pointer);

    pointer.clearEntityModifiers();
    pointer.registerEntityModifier(new MoveModifier(
        1.0f, 540, 960, 1000, 1000,
        new IEntityModifierListener() {
            public void onModifierStarted(IModifier<IEntity> pModifier, IEntity pItem) {}
            public void onModifierFinished(IModifier<IEntity> pModifier, IEntity pItem) {
                clickSound.play();

                pointer.clearEntityModifiers();
                pointer.registerEntityModifier(new MoveModifier(
                    1.0f, pointer.getX(), pointer.getY(), 500, 2500,
                    new IEntityModifierListener() {
                        public void onModifierStarted(IModifier<IEntity> pModifier, IEntity pItem) {}
                        public void onModifierFinished(IModifier<IEntity> pModifier, IEntity pItem) {
                            pointer.clearEntityModifiers();
                            pointer.detachSelf();
                        }
                    },
                    EaseCubicInOut.getInstance()
                ));
            }
        },
        EaseCubicInOut.getInstance()
    ));

沿第一条路径的指针移动正如所料，然后clickSound播放，然后什么也没有发生。第二MoveModifier没有任何效果。我在做什么错在这里？

The pointer moves along the first path as expected, and then the clickSound plays, and then nothing happens. The second MoveModifier doesn't have any effect. What am I doing wrong here?

推荐答案

我不知道为什么你的code不工作，但我认为你可以使用实现同样的事情 SequenceEntityModifier ：

I'm not sure why your code is not working, but I think you can achieve the same thing using the SequenceEntityModifier:

scene.attachChild(pointer);

    pointer.clearEntityModifiers();
    pointer.registerEntityModifier(new SequenceEntityModifier(
        new MoveModifier#1(...),
        new MoveModifier#2(...)));
