please format your code posting by pasting it into the

```auto
</> code button

```

of the editor header menu ( context name: Preformatted text )  
it looks like  
```  
type or paste code here  
```

also can use the ``` manually above and below your code.

thank you.

* * *

what are these

```auto
if (x> rectX && x < rectX + rectWidth && y > rectY && y < rectY + rectHeight) {

```

lines supposed to do?  
what is x y used for?

Thank you for taking a look. The above code you have a question about is a proximity detection, but I’m struggling with making proximity for the below object.

```auto
fill(127);
    rect(location.x,location.y,20,20);

```

The x and y are just up there temporarily (I was trying to represent locaton.x with x and location.y with y). It didn’t work, but I want it so that if the rectangle’s position is within the green rectangles it will reset to position (20,650). It’s like a maze where if the object touches a wall it resets.
