Need tutorial or help in space physyc
I'am looking for some tutorial "how to create Space Physic" i find script
This is a 3D First Person Controller script that can be used to simulate anything from high speed aerial combat, to submarine warfare. I have tried to make my variable names as descriptive as possible so you can immediately see what they affect. The variables are sorted by type; speed with speed, rotation with rotation ect... I have also included generic ranges on variables that need them; relative upper and lower variable limits. This is because some of the variables have a greater effect as they approach 1, while others have greater impact as they approach infinity. If for some reason the ship is not doing what it is supposed to, check the ranges, as some variables create problems when they are set to 0 or very large values.
Also note the separate script titled Space Flight Script. This script has been optimized to better suit space combat. The effects of gravity, drag and lift are removed to better simulate flight in zero-gravity space.
This script uses controls based off 4 axis. I found these parameters worked well... Name : (Roll, Pitch, Yaw or Throttle) Gravity : 20 Dead : 0.001 Sensitivity : 1
Axis for each control (Axis based off a standard flight joystick). Pitch: Y- Axis Roll: X - Axis Yaw: 3'rd Axis Throttle: 4'th - Axis
How to use this script:
Drag and Drop the Transform and its Rigidbody onto the variables Flyer and
FlyerRigidbody in the inspector panel. Remember to change the rigidbody's Drag
value. If you dont change this, gravity will be unrealistic... (I set drag to 500)
Change the variables to simulate the flight style you desire.
Create a prefab of your GameObject, and back it up to a secure location.
*Note: This is important because none of the variables are stored in the
script. If for some reason Unity crashes during testing, the variables
are not stored when you save the javascript, but when you save the game
project.
Save often and enjoy!

/* The ratio of MaxSpeed to Speed Const determines your true max speed. The formula is maxSpeed/SpeedConst = True Speed.
This way you wont have to scale your objects to make them seem like they are going fast or slow.
MaxSpeed is what you will want to use for a GUI though.

But i don't have idea how to use this script i will create this "Pitch" , "Roll", "Yaw", "Airbrake", "Aftefburner" but i don't know how to set this correct...
Cane someone do this for me and send me project .unity3d ? or tell me what i have to do?
