Saying where helicopter crashed
I found the OnHelicopterKilled hook and I was wondering if its possible to say where the helicopter crashed in the map?
Get its Transform maybe?
(pos = vector3)
var worldSize = ConVar.Server.worldsize;
const float scale = 150f;
var x = pos.x + worldSize/2f;
var z = pos.z + worldSize/2f;
var lat = (int)(x / scale);

Dude, ofcourse it wont compile, he gave you an example, its not a valid c# code
Before making plugins atleast learn the syntax

You should see syntax errors like that before you try to compile it, you're probably not using a proper IDE setup. 

Here's a simple guide on how you can setup your workspace:

If you're a member of a university, you might be eligible for a student license. JetBrains Rider is a good alternative to Visual Studio.
