How to make screen shake in gdevelop 4

So while i was making my game i wanted to make the screen shake when the player dies
but i don’t know how.

so here’s a look at the death code there are three because i have two enemies and a bullet:

Try move the Y of your camera like camera.Y() + randomInRange(-20,20)

i copy and pasted it but it has a syntax error in parameter #2.

i’m using gdevelop 4 maybe it only works in 5
