Unity Analytics - Custom Events

Evening forum,

I have been using Playmaker in Unity for a little over 3 years now, so you can probably imagine my frustration when tying to set up Unity Analytics, not Game Analytics, and create custom events in C# script. I have very little knowledge when it comes to programming script so I am having trouble setting up custom events without a Playmaker action set to help me.

If anyone could give me any pointers in how to create Analytics custom scripts, I only need help with a simple one, if it even works the way that I am thinking. I want to send a custom event, "LevelCompleted", to Analytics when a character finishes a level. With the little knowledge I have, I am trying it with OnTriggerEnter. I am not sure if that is right or wrong, so any help would be greatly appreciated.
