I’m a little perplexed. Is there anything that happens between Setup() and Draw() in the sketch?
This is my 20th or so ‘mover’ based project. No arrays on this one, but a basic Mover class (position, velocity, radius, etc).
In the code below: the first call to console.log(mover) in Setup(); shows me all the created object’s details in the console - like you would expect. It is a valid object with parameters, etc.
The second call to console.log(mover) comes back as **undefined**.
How could I have lost my mover object between Setup() and Draw().
I have done a variation where the class declaration is on the script.js page along with Setup() and Draw(). Same thing happens - I have an object in Setup() which is gone missing by Draw(). How could I have lost the mover object between Setup() and Draw().
Thanks, Paul
```auto
let mover;
function setup() {
createCanvas(400, 400);
let mover = new Mover(200, 200);
console.log(mover);
}
function draw() {
background(50);
console.log(mover);
}
```

Hello, @pbissell, and welcome to the Processing Forum!
You have this in your `setup()` function definition:
```auto
let mover = new Mover(200, 200);
```
With `let`, it defines `mover` as local variable in the function. Outside the function, `mover` refers to a global variable by that name that you declared prior to the `setup()` function. Though it was declared, it was not initialized with an object.
Inside `draw()`, you access the undefined global variable.
_Edited on June 25, 2021 to clarify the explanation._

**And to easily rectify,** just delete the “let” inside setup so that line reads:
`mover = new Mover(200, 200);`

OMG. Thank you so much. I double Let!

Wow. Thank you so much. I double Let and couldn’t see it. Thank you!

See [p5.js: Variable Scope](https://p5js.org/examples/data-variable-scope.html).
It is OK to have global and local variables with the same name, so long as you are careful. For example, you might write a function with many lines of code and some local variables. Make sure those variables are declared properly within the function, using `let`. Then, if you decide later on to use the function within a longer script, you will not need to be concerned about whether that script contains global variables with the same names as the local variables within the function.
