Update() OnCollisionEnter

Code (CSharp):

1. void Update (){
2.         OnCollisionEnter2D (Collision2D coll)
3.         {
4.             alpha = alphacolor.GetComponent<SpriteRenderer> ();
5.             Color opa = alpha.color;
6.            
7.             if (coll.gameObject.name == "Bin") {
8.                 opa.a = 0.5f;
9.                 alpha.color = opa;
10.             }
11.         }

How to write like this ?? I get error when I write it like this, any help will be appreciate and thanks

 

OnCollisionEnter is a method itself, so you can't put it in the method "Update()"

look here for more info:http://docs.unity3d.com/ScriptReference/MonoBehaviour.OnCollisionEnter2D.html

PS - Unity's scripting API goes into detail on many things that you may need answered, often googling it will find you a faster answer to your question rather than asking it on the forums and having to wait =)

 

If this is the level of experience you have then it's clear you don't understand programming at all, and should spend at least 2 weeks with a good C# instruction book to warm up... or you'll keep trying to pilot a space shuttle (which is burning up in orbit) using a piece of celery in a plug socket.

 

I know it a little about it, what I want to ask is how I can check mouseUp onCollisionEnter. Bcoz I know the mouseUp only can check at update coz it update and check it every frame. Then I need to know how to check the mouseUp onCollisionEnter
