Random.value ???

Unity Engine

Hello everyone!
I am trying to make a drop chance system when killing enemies in my game.
I am doing this:

if (Random.value <= itemChance.probability) {
//drop that item! :smile:
}

That works! However, will this also work if I want something way less than 1% drop?
So I change the probability to something like .0001 or something crazy small?
Or will it never actually hit?

Try this:

void Start() {
   StartCoroutine(RandomChance());
  }
long runs = 0;
int matches = 0;
float nextprint;
IEnumerator RandomChance()
{
   WaitForSeconds wfs = new WaitForSeconds(.4f);
   while (true)
   {
      for(int i = 0; i < 200; ++i)
      {
         float f = Random.value;
         if (f <= 0.0001f) matches++;
         runs++;
      }
   if (Time.time >= nextprint)
   {
        print("Runs = " + runs + "  matches = " + matches);
        nextprint = Time.time + 2;
        yield return wfs;
   }
   else yield return null;
 }
}

No problem. :slight_smile: For any future readers, who may not want to actually run that code… yes, it does work :slight_smile: heh.
