Control the character while on air?

Questions & Answers
1

What can i do so the character can be controlled while on air ? Some people told me to remove the ifgrounded clause, but that brings a couple of errors, such as, expected } or, found else etc.

Here is the script. please tweak it and then send it back. I don’t know what to do. Thanx

Dude, forget about this script: it’s one of the CharacterMotor-like scripts that come with Unity, all of them way too complex to be modified. Use a script based on the [CharacterController.Move][1] example - it’s easy to understand and modify. This is the mentioned example edited to allow control when in the air:

var speed : float = 6.0;
var jumpSpeed : float = 8.0;
var gravity : float = 20.0;

private var vertSpeed : float = 0;
private var moveDirection : Vector3 = Vector3.zero;

function Update() {
    var controller : CharacterController = GetComponent(CharacterController);
    // calculate the horizontal direction to move
    moveDirection = Vector3(Input.GetAxis("Horizontal"), 0,
                            Input.GetAxis("Vertical"));
    // rotate it to the player orientation
    moveDirection = transform.TransformDirection(moveDirection);
    moveDirection *= speed; // apply the horizontal speed
    if (controller.isGrounded){
        vertSpeed = 0; // if grounded the vertical speed is 0...
        if (Input.GetButton ("Jump")){ // unless it jumps
            vertSpeed = jumpSpeed;
        }
    }

    // gravity increases the down speed as a function of time
    vertSpeed -= gravity * Time.deltaTime;
    // add vertical speed to the moveDirection
    moveDirection.y = vertSpeed;
    // and move the controller in the direction defined
    controller.Move(moveDirection * Time.deltaTime);
}

Assign this script to your character, and disable the horrible script you’ve posted here. Play around with your player, and feel free to modify this script - you will be able to understand how it works, for sure.
