The previous article introduced the initialization method of the main character of the game. Next we will implement other methods of the main character. First, let's take a look at the runAnimation method. We will use this method to play the animation of the main character:

-(void)runAnimation:(CCAnimation*)animation{    if (_curAnimation == animation) {        return;    }    _curAnimation = animation;    if (_curAnimate) {        [self stopAction:_curAnimate];    }    _curAnimate = [CCActionRepeatForever actionWithAction:                   [CCActionAnimate actionWithAnimation:animation]];    [self runAction:_curAnimate];}

The code first checks whether the animation to be played is the same as the animation currently being played. If the animation is the same, exit directly. Then, if the animation is being played, stop it.

Next, create a permanent loop action for the animation to be played, and then run the action.

It is relatively long, and I will not elaborate on it here. The information you need is fully covered in the above two series of blog posts. one thing to note is that I started to write such code, so I didn't have a strong grasp of the class elements at the beginning. It is reasonable to say that this method is required by all game players, so they should be placed in their parent class. this is indeed the case. I am doing this in another RPG Game <the soul of pandatv> and we have the opportunity to repeat it.
