Hello. I need help with setting an area of pixels in an if statement. I am still kind of new here so please don’t pay attention to any wrong terminology I use.
In an _if_ statement I need to use not only the one position as an argument, but an area of pixels and I don’t know how to do it. I will try to use the example of what I have in my mind below and use // where I don’t understand how to do the thing.
```auto
if(xpos == //area from pixels (0,5) to (15,5)){
xspeed*=-1
}
```
This is just a random example but I am having troubles of setting that area in a code, so I would appreciate some help if you have time 🙂

`if(xpos >= 0 && xpos <= 15){`
Additionally you can check whether ypos == 5

Hello @MaxU89,
Take a look at this example:
> **[Mouse Functions / Examples](https://processing.org/examples/mousefunctions.html)**
>
> Click on the box and drag it across the screen.
And also examples that come with Processing:
Do a search for _Logical Operators_ on the Processing website if you are not familiar with these.

Yes
```auto
// Test if the cursor is over the box
if (mouseX > bx-boxSize &&
mouseX < bx+boxSize &&
mouseY > by-boxSize &&
mouseY < by+boxSize) {
overBox = true;
```
