Hi guys,

I?ve a problem. If I put "Random(x, y)" in a main do/loop cycle it works fine. But if I put it in a function, and I call the function inside the do/loop, it doesn't work. Is it a common problem or just mine? Tested on Windows and Android.


Thanks so much for the support!

You'd need to post some code to diagnose the issue fully.
But my guess is, you are using a variable that you haven't declared as global. Therefore, teh function makes its own local version of that variable name.

Variables x and y will be 0 inside your function if you haven't declared them as global or set their value inside your function. Each function use a separate set of variables than the rest of your code. This is called variable scope. All variables are by default local and is separate for your main code and each function. By declaring a variable as global it will retain its value both inside and outside of functions.

I'd also guess that you haven't declared x and y as global variable, but without any sample code, or reply from you to confirm, it is hard to say for sure.
