Very basic flight sim script

My first post here I have been messing with unity for a while but scripting was out of my league so knuckled down and stopped playing with the bells and whistles which unity has heaps of. I tried to unravel the provided C# scripts but their complexity and intricacy left me with more questions than answers.
Anyway after a few weeks I have come up with this most basic of basic flight sim scripts that may be of use to other beginners. You need nothing more than a Main camera, flat basic terrain for visual reference, some randomly placed spheres to fly around, the directional light and a cube turned into a flat rectangle. No other scripts or anything fancy. Just attach the main camera to the cube and this script to the cube and you're off and flying. To the admins I hope this is okay it is a bare bones basic (my first C# script) flight sim with most lines of code explained as to what they do. WASD and All arow keys are used to fly and easy to see in the script what functions are attached to those keys.. Hope this is okay and beginners get some use from it

 

what are the controls in it, like, throttle up, pitch up, and how do i change the controls in the script

 

i'm telling for when i put arrow up the plane banks left

 

and if you'd like to join my unity collaborate, (since im a beginner and i need a pros help,) you are welcome, and so is anyone, let me know if you want to join

 

And Plz add engine physics, since it never goes forward

 

You do realize that the original post was from 2016 correct?

 

yes

 

It's unlikely that you're going to get a reply from the OP as they haven't logged in for five years.

If you need help with a script, I'd suggest asking in https://forum.unity.com/forums/scripting.12/ and explain what you've tried and what you want to get it working. It's unlikely that you'll find someone to do the script for you.
