Random chance out of 2

Unity Engine
1

So in my game i would like there to be a random chance that zombies get decapitated. i have read a few posts on the topic but cannot get it working.

var particles_blood : GameObject;
var zombie_corpse : GameObject ;
var decap_corpse : GameObject ;
var slicing_sounds : GameObject ;
var randValue = Random.value ;

function start () {
randValue(0,1) ;
}
function OnCollisionEnter(collision : Collision)
{
  if ( collision.gameObject.tag == "Choppa" ) 
  {
    if (randValue < .45f);
	{
    Instantiate(particles_blood, transform.position, transform.rotation);
	Instantiate(slicing_sounds, transform.position, transform.rotation);
	Destroy (gameObject) ;
	}
    if (randValue <.10f);
	{
	Instantiate(slicing_sounds, transform.position, transform.rotation);
	Instantiate(decap_corpse, transform.position, transform.rotation);
	}
}
}

Sorry if i’ve made a stupid mistake, but i have a limited knowledge of coding. Help would be much apprieciated as i’ve been going at this for the last couple of hours.

I don’t use javascript, but I am pretty sure this is the same as C#.
You are actually trying to randomize a value between 0 AND 0.
Random excludes always the last number and Random doesn’t create float (unless I am mistaken).

So you always get the same value which should be 0.

Try to use this before your if(s) : Debug.Log("Here is the value of the random : " + randValue );
You will always see what is the value of your randValue (to confirm).

Hope this helps.

PS: If you want to get some random value try to use a 100% where you randomize between 0 and 101. So you can keep your ratio easily.

Remove randValue(0,1) ; from your start function and instead of declaring it as Random.value declare it as a float and set it to a random value in the start function.

var randValue : float;

function Start () {

	randValue = Random.value;

}

function Update () {

	Debug.Log (randValue);

}

Thank you, this worked perfectly :).

Actually, i hadn’t noticed it before but it clones the ragdolls. i have altered the script to allow a third ragdoll version.

In the video it better illustrates my problem. I’m not sure how to fix this but i may go for a different method of gibbing so it is more precise.

Debug.Log your random value and post the results you get. Also, you might collide several times with the same collider as you don’t disable/destroy them in the second if statement.
