Need Help for aeroplane scrip
Hi guys, for some reason my aeroplane script will not allow me to pitch upwards can you guys have alook at it thanks.

var flyerRigidbody : Rigidbody; var seaLevelTransform : Transform;
// Assorted control variables. These mostly handle realism settings, change as you see fit. var accelerateConst: float = 5; // Set these close to 0 to smooth out acceleration. Don't set it TO zero or you will have a division by zero error. var decelerateConst: float = 0.065; // I found this value gives semi-realistic deceleration, change as you see fit.
/* 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.

I think there are some formatting issues. Can you see if you can make the body of the post all one code formatted block for readability? If you are looking for assistance, you need to spend time making your question as readable as possible. Since this is a LOT of code, you are making the responders work hard.
You can edit your question - highlight the code using the mouse and click on the button with the "101" at the top to format the code for you.
