How do I make jump scares?

[Theforgot3n1]

Title says it all. I know how to make entities active when you enter/exit an area or pick something up. But the one thing I want to know is how do I add the sound? You know, like the loud scream or yell when a naked dead guy comes flying at you.

You just have to look around at:

and you can probably find it.

If you're lazy or can't find, the function is called "SetEntityActive("name of entity", "false/true(deactivate/activate)");" But it really is important to be tenacious when you're scripting; or else it's really gonna be an uphill battle. :/
