Hack prevention

Hello I am wondering are there ways to prevent hacking from taking place? I am a noobie and noticed that code can easily be hacked, but if you use playmaker would that reduce the chances of this occuring? As its a visual scripting tool and not really code generated by me?

I dont own this one but it might be worth a shot: https://www.assetstore.unity3d.com/#/content/10395
