exponential speed.

[anon_43712245]

I m doing this little game using the 1stpersoncontroller asset and I want the run speed to increase. I am not a coder so please, very simple language please ^_^;.
Let say you press foward , you run to a speed, if you hit a object well you loose your pace and goes back to the default walk speed. But imagine this. A guy is running on a a boat used to launch planes from the sea okay , well i want the guy to run really really really fast after a little while so he could jump really far. Damn it s so hard to explain. for something so simple…

Understand ? Help ?

edit:

The speed starts increasing after a delay of let s say 3seconds then goes up fairly fast.

For an object to gain speed exponentially, if you have a CharacterController on it you can access the velocity directly and do the following in Update

if(Input.GetButton(“Speed Boost”))velocity*=velocity;

however I think that will increase the speed way faster than you want since it will increase every frame. You probably just want something like:

if(Input.GetButton(“Speed Boost”))velocity+=; where the velocity will increase by meters per second each frame.

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

private var moveDirection = Vector3.zero;
private var grounded : boolean = false;

function FixedUpdate() {
if (grounded) {
// We are grounded, so recalculate movedirection directly from axes
moveDirection = new Vector3(Input.GetAxis(“Horizontal”), 0, Input.GetAxis(“Vertical”));
moveDirection = transform.TransformDirection(moveDirection);
moveDirection *= speed;

if (Input.GetButton (“Jump”)) {
moveDirection.y = jumpSpeed;
}
}

// Apply gravity
moveDirection.y -= gravity * Time.deltaTime;

// Move the controller
var controller : CharacterController = GetComponent(CharacterController);
var flags = controller.Move(moveDirection * Time.deltaTime);
grounded = (flags CollisionFlags.CollidedBelow) != 0;
}

@script RequireComponent(CharacterController)

Thanks a lot now to implent it in this i add it under the jump if ?

th script you gave me, does it work by just running with the foward buttons ? or is it another button ? If it is another button where do i set it : ) ?

Thanks so much man

You can set buttons and axis on the Edit > Project settings > Input

Here is a scene and the script Control.js that is an expansion of the one founded in the documentation to suite your needs

The variables had comments for you to understand what they do, and you can change them in the Unity Editor

To stop the acceleration and start all over again set time = 0.0 when the character strike an object or another event that stops the character and he will start walking again.

got it !! works superb. Exept when i hit an object in mid air but i ll figure it out i m sure. THanks so much sacrifices a goat in your honor
