How to create a faster and faster function call?

Questions & Answers
1

I have a script that creates a coin at rate seconds and every rate seconds, rate is decreased by fasterRate. This should create the coins faster and faster, but the InvokeRepeating() called with rate is only called at start so that it doesnt get faster and faster but just stays the same rate. I need a way to call CreateCoin() faster and faster. Thanks!

#pragma strict
var xpos : float;
var spawnpoint : Vector3;
var coin : GameObject;
var rotation : Quaternion;
rotation.eulerAngles = new Vector3(0, 0, 0);
var newCoin :Object;
var rate : float = 3.0;
var fasterRate : float = 0.1;

function Start () {
InvokeRepeating("CreateCoin", 1, rate);
}

function Update () {
Destroy(GameObject.FindWithTag("Coin"),10);

}

function CreateCoin(){
	xpos = Random.Range(-50.0,50.0);
	spawnpoint = new Vector3(xpos, 80, 0);
	
	var myColor : Color;                       // This is just working for another part of my script, Please Ignore.
    var mode : boolean = Random.value > 0.5f;
    var rand : float = Random.value;
    var index : int = Random.Range( 0, 3 ); 
    myColor[index] = rand;
    myColor[( index + ( mode ? 1 : 2 ) ) % 3] = 1;
    myColor[( index + ( mode ? 2 : 1 ) ) % 3] = 0;
    
	newCoin = Instantiate(coin, spawnpoint, Quaternion.identity);
	//newCoin = newCoin as GameObject; 
	//newCoin.renderer.material.color = myColor;
	
	rate = rate - fasterRate;
}

Rather than use InvokeRepeating(), just use Invoke() at the end of CreateCoin(). Insert between line 36 and 37:

Invoke("CreateCoin", rate);

and in Start():

Invoke("CreateCoin", rate);

It’s simplest to use a coroutine in a loop, along with WaitForSeconds:

function Start() {
    while (true) {
        CreateCoin();
        yield WaitForSeconds(rate);
        rate -= .1;
    }
}

Although you’d want to put in some condition for making rate not go too low.

I think you should use coroutine();

And pass a variable in hold time(yield).
In Update() decrease this variable.

Try this and you will get the exact result you want.
