为两个精灵和引擎创建两个修饰符的序列

Question

I am trying to create two sprites and applying a RotationAtModifier at each. I want to be able to run both in a sequence, meaning Modifier1 on Sprite1 and after that Modifier2 on Sprite2. Is there any way to achieve that. I tried sequence and loop modifiers but i think they can be used for applying multiple modifiers for a single sprite. Correct me if I am wrong.

final RotationAtModifier rotMod1 = new RotationAtModifier(50, 0, 90, 830, 150){

@Override
protected void onModifierStarted(IEntity pItem) {
    getEngine().runOnUpdateThread(new Runnable(){
    public void run(){
        if(! Sprite1.isVisible()){
            Sprite1.setVisible(true);       
        }}
    });
}

@Override
protected void onModifierFinished(IEntity pItem) {
    getEngine().runOnUpdateThread(new Runnable(){
    public void run(){
        Sprite1.setVisible(false);  

        }
    });
}
};
RotationAtModifier rotMod = new RotationAtModifier(50, 0, 90, 830, 150){

@Override
protected void onModifierStarted(IEntity pItem) {
    getEngine().runOnUpdateThread(new Runnable(){
    public void run(){
        if(! Sprite2.isVisible()){
            Sprite2.setVisible(true);       
        }}
    });
}

@Override
protected void onModifierFinished(IEntity pItem) {
    getEngine().runOnUpdateThread(new Runnable(){
    public void run(){
            Sprite2.setVisible(false);
            Sprite1.registerEntityModifier(rotMod1);
        }
    });
}
};

mScorpius.registerEntityModifier(rotMod);
