Good morning Soloh,

Could you please edit your post and format the code? Open your sketch in Processing, click on `Edit / Auto Format`, and copy the formatted code In your post. In your post click on `< /> Preformatted text` and paste it on the right position. The end result should look something like:

```auto
int x=500;
int o=600;
// ...
// rest of your code
// ...
  x = x - 1;}
}

```

About your issue. At the end of `void draw()` you’ve placed an if/else if statement. The problem is that once x is higher than 600 and enters the `else if` part, x gets reduced. This means that in the following draw loop x is lower than 600 again and it enters the `if` again.  
As a result your animation keeps rapidly switching between `if` and `else if` around x = 600. Do you understand now why your issue is happening?

There are several ways to solve this, but if you want to maintain your current structure I’d go for a [boolean](https://processing.org/reference/boolean.html) that keeps track of the swing direction. For instance, if it’s true it should swing to the right, and once it reaches x = 600 it becomes false. Using that value, you could adjust your `else if` conditions.
