Call a function multiple times

Questions & Answers

Hi, I’m wondering if there is something I’m missing here.

Is there a fast, and easy way to call my function “Spawn” from the start menu 3 times (using the amount variable)?

Seems like this should be obvious but I can’t figure it out. Here’s the code.

`//Objects To Spawn

var objectsToSpawn : GameObject;

//Spawn Locations

var spawnLocations : Transform;

//spawn amount

var amount = 3;

function Start()
{

Spawn(amount);

}

function Spawn()
{

//Select From Objects To Spawn

var thingToSpawn : int = Random.Range( 0, objectsToSpawn.length );

//Select From Spawn Locations

var placeToSpawn : int = Random.Range( 0, spawnLocations.length );

Instantiate( objectsToSpawn[thingToSpawn],

spawnLocations[placeToSpawn].position,transform.rotation);

}
`

I’m trying to call the spawn function 3 times. Any ideas where I can stick the var amount (if anywhere)?

Thanks

This is how your Start function should be:

var amount = 0;

function Start(){
   for (amount=0; amount<3; amount++)
      Spawn();
}

Watch out: I cannot say if the rest of your code is correct (even because you have not formatted it properly): this is simply the logic behind calling a function 3 times as the application starts.

You can use a loop to iterate through the amount,

function Spawn (quantity : int) {

    for (var i : int = 0; i<quantity; i++) {
        //Select From Objects To Spawn
        var thingToSpawn : int = Random.Range( 0, objectsToSpawn.length );
        //Select From Spawn Locations
        var placeToSpawn : int = Random.Range( 0, spawnLocations.length );

        Instantiate( objectsToSpawn[thingToSpawn], spawnLocations[placeToSpawn].position,transform.rotation);
    }

}

You could also pass more variables to the function, to switch objects or so:

function Spawn (quantity : int, thing : GameObject) {}

I know it is a very old post. But for anyone wanting to call a function repeatedly InvokeRepeating can be used.

 // Waits 2 seconds, then calls the function named SpawnObject every 1 second until canceled
    InvokeRepeating(nameof(SpawnObject), 2f, 1f);

To stop calling the function just use:

 CancelInvoke(nameof(SpawnObject));
