Using DNSpy and Unpacking Assembly-UnityScript.dll

So, I've used many different .NET upackers to try and read Assembly-UnityScript.dll. I've used dotPeek, DNSpy, and Microsoft Visual Studio ILDASM. However, the code is unintelligible. All function names and methods are some form of "DF34_XXXXXXXXXXXXXXXXXXXXXXXX" with XXX.... being some random string of numbers and letters. Obviously, despite having the code unpacked, I can't tell what anything does. Is there some way to get more descriptive names or some way to actually see what the code is doing?

I was asking this to myself these days. Unfortunately, I searched the internet and found no one who knew how to explain exactly how to deal with it.
However, I hope my college will come up with some similar subject in the future. For now, we are waiting for someone who understands and can explain something to us.
