Question by cidmodder · Dec 21, 2010 at 06:32 PM · javascriptspawnexceptioninvalidcastexception

Spawning objects with random sizes and random seperation

I'm trying to spawn spheres that are randomly separated and have random sizes. Right now my script just spawns one sphere and I get this error

"InvalidCastException: Cannot cast from source type to destination type. Particle Script.Start () (at Assets/Particle Script.js:10)"

Here is my script

var numberofpartices= 10; var particles=transform; var seperation= Random.Range (-10,10); var particlemaxsize=5;

function Start () {

for (var i : int = 0;i < numberofpartices; i++) { var numRandom: int = (Random.Range(0,10)+.5); var particleMade: GameObject = Instantiate (particles, Vector3(i*seperation, 0, i*seperation), Quaternion.identity); particleMade.transform.localScale= Vector3.one *numRandom; }

}

how do I get it to spawn randomly sized and randomly spaced spheres? thanks for the help!

your second line is incorrect. instead of

var particles = transform;

you should have:

var particles : Transform;

then this object will have an exposed variable in the inspector called "particles". You will want to take your sphere prefab (you are using a prefab, right?), and place it in there. You can also change your Instantiate line to:

var particleMade = Instantiate(...);
