for( int x=-600; x\<=600; x=x+60){  
for (int y=-600; y\<=600; y=y+60){

quiero hacer esta grilla en un size(600,600) pero no se como meter las variables que puedan ser luego modificadas con eventos de teclado/mouse, como para ver la grilla mas pequeña o mas grande, con los numeros de ahi arriba. si me ayudan con como poner las variables para que luego no sea una grilla estatica me serian de mucha ayuda

Hello,

Some resources for you:

> [@Zig Zag or Wavy or Spiral or Dotted lines eyes](https://discourse.processing.org/t/zig-zag-or-wavy-or-spiral-or-dotted-lines/31547/2):
>
> Hello, I encourage you to look at the resources available here: Beginner The Processing website has references, examples, tutorials, etc. [https://processing.org/](https://processing.org/) The Processing PDE (IDE) has lots to offer! An exploration of the menu items will reveal what is available! You will find libraries, tools, examples and more! For example: [image] The Coding Train [https://www.youtube.com/channel/UCvjgXvBlbQiydffZU7m1\_aw](https://www.youtube.com/channel/UCvjgXvBlbQiydffZU7m1_aw)[https://thecodingtrain.com/](https://thecodingtrain.com/) Happy Coding [https://happycoding…](https://happycoding.io/tutorials/processing/)

Lots of good stuff in there to get you started!

Once you go through the basic tutorials these may help:

- [for / Reference / Processing.org](https://processing.org/reference/for.html)
- [map() / Reference / Processing.org](https://processing.org/reference/map_.html)
- [text() / Reference / Processing.org](https://processing.org/reference/text_.html)

Try changing the 60 to a variable and modifying that variable with mouse movement using the map() function.

Have fun!

`:)`

thanks! I finally change the code and assigned a variable
