Welcome to the forum!

This is a good starting point:

[https://www.processing.org/reference/](https://www.processing.org/reference/)

Please note that here different things are gathered :

- variables / global properties like mouseX and mouseY

- functions like line() - you can recognize them because of the brackets(). There are different kinds of functions. E.g. line() doesn’t return something (it’s a command), abs() does. These get parameters (that what’s inside the brackets), some don’t like loop() / noLoop() / push() / pop() …

- Also operators can be found in the reference. And other things.
