Not compatible with the argument list

Hi! I was looking for an answer to this, but without any luck so far...

I have this code:

var particleDer : ParticleSystem;
function Start ()
{
}
function Update ()
{
OnTriggerEnter();
}

function OnTriggerEnter(col:Collider)
{
if (gameObject.tag == "Bubbles")
{
particleDer.Play();
}
}

I´m getting this error code: "The best overload for the method ´ScriptName.OnTriggerEnter(UnityEngine.Collider)´ is not compatible with the argument list ´(UnityEngine.GameObject)´.

Thanks in advance!

 

Use code tags please. You shouldn't be calling OnTriggerEnter every frame in Update, so remove that code. OnTriggerEnter runs when a collider enters the trigger.

Sorry about the code tags (newbie alert!), and thanks you for your kind answer, Eric. My mistake, I thought OnTriggerEnter was a custom function name.

Now, I have several gameObjects (with rigidBody attached) falling and bouncing into a plane. When they hit that plane, I want something to happen, but nothing goes on:

Code (JavaScript):

1. var particleDer : ParticleSystem;
2.  
3. function Start ()
4. {
5.  
6. }
7.  
8. function Update ()
9. {
10.  
11. }
12.  
13. function OnTriggerEnter(col:Collider)
14. {
15.     if (col.tag == "Ring")
16.     {
17.     print("Go on");
18.     //particleDer.Play();
19.     }
20. }

I´m sorry, I know this must be very basic stuff, but I can´t figure it out... Thanks.

 

You'd want OnCollisionEnter instead. BTW, it's better to use CompareTag instead of using string comparisons.

please read http://docs.unity3d.com/Manual/CollidersOverview.html espacially section "Script action taken on collision"

 

Thank you very much, Eric and element wsc
