Help a noob with "Human Flying" script?

Hello guys, and thanks for visiting my thread.
So, yeah... i'm new to Unity, and in that process of "What should i do first", i decided that getting a base/complete script to use as a reference for the main script in my project-- a simple RPG game that resembles ALfheim Online (yes, here goes another game inspired in SAO. Everyone's tired of it, i know..)-- would be a awesome idea, since i know almost nothing about scripting, but i'm willing to learn.

So, the reference that i have is this video here:

.
The flying stuff starts at 3:00, but i'm using chibi-styled characters (AoTTG style) instead of realistic models.
Could someone give me a script that works like this one for me to use as a base, or (for learning purposes) explain me how this "human flying" mechanic works? I guess can deal with the details and complex explanations, but examples would be very appreciated...

Thanks in advance~!

 

You could use a rigidbody and addforce to the proper axes, not sure if 2d or 3d you mean with AoTTg whatever that is, but http://unity3d.com/learn/tutorials/modules/beginner/2d/2d-controllers for 2d controllers i found easy to make a sort of jetpack guy from that video very well explained.

For 3d i have no clue and if you dont know scripting i doubt you should start there.

 

Thanks for your reply!
Here's a video of AoTTG gameplay, for reference:

I'm aiming for my project to basically look like this game in character style and camera movement-- chibi-styled characters and third person camera--, and i'll be "replacing" all the Shingeki no Kyojin related systems (3D Maneuver Gear, Special Attacks, Titan AI and so on) for ALO-like systems (Flying and Hovering, Magic and Skill casting, simple combo system and so on). I decided on priorizing the flying system since it's the most important one in the game and in the anime series, but maybe i should give the game a more solid base first...
