up-todate Turret modding guide?

[Heymom]

Hey i am trying to make a simple EMP turret, but its not going so well for me.

I am looking at current turret mods and trying to make a the defs while referring to the http://rimworldwiki.com/wiki/Modding page.

The problem is that the wiki states the examples are from alpha 11? so i aint sure if the mods i am looking at or the webpage are wrong.. because they dont match classes etc

example:
wiki structure;
BaseGun
BaseHumanGun   
BaseBullet

mod structure (more vanilla turrets);
BuildingBase
BaseBullet
BaseHumanGun

There are also some tags that aint in the wiki.. ya so kinda confusing, the turret mod i am using as reference, ain't updated correctly either its a quick fix.

Hope my post makes sense..

edit: up-to date, as in for B18.
