What is this error and how do I fix this?

Question

I am making a shooter game, and every time in one part, I get an error that crashes the app. I couldn't copy the error, but the error has 2 parts that I remember: it said not supported error, and it had a negative line number. How do I fix this?

Answer 1

line 495: Math.random()
This is what causes line 496 error
And then cause line 427 error

A tip to find error: see the error line, and check where every value comes from

And other than this, there're still other bugs, try to find yourself first
