Question How to reset position after collision

I was watching a tutorial on unity and it shoed how to reset my characters position after a collsion This is the code That was supposed to work

Code (CSharp):

1. void OnCollisonEnter2D(Collision2D collision)
2.     {
3.         _rigidbody2D.position = _startPosition;
4.         _rigidbody2D.isKinematic = true;      
5.     }

This doesnt give me any errors but it just doesnt reset my character to the start position after I collide with something.How do I make this work?

 

first of all use Debug.log and check if the collider happens in the first place.
second better change transform.position and rigidbody position also.

 

I put a debug log in.I dont know if I put it correctly but this is it:

Code (CSharp):

1.   void OnCollisonEnter2D(Collision2D collision2D)
2.     {
3.         _rigidbody2D.position = _startPosition;
4.         _rigidbody2D.isKinematic = true;
5.         Debug.Log("hi");
6.     }

it didnt put anything in my debug log but my character is colliding with the squares when it moves into them.

 

Make sure both colliders arent marked as trigger and that both are on the same layer

 

how do I check to make sure they are on the same layer

 

In the inspector, on the top right corner, you'll see a dropdown called layer, check if the layer is the same with both GameObjects, according to Physics 2D, I'm pretty sure the gameobjects have to be on the same layer to be able to collide.

 

they all have the layer default but its still not working

 

Is there a rigidbody on one of the objects? Is trigger not marked on the collider for both objects?

 

Is trigger is unchecked for all objects

 

they both have is trigger unchecked

 

also that code is excatly what the tutorial told me to put

 

Hello

Your code is not right. Take care of spelling.

OnCollisionEnter2D (you forgot "i")

 

check all of this in your project:

-Both objects must have colliders (2D)
-At least one of them has a rigidbody (2D)

And then copy this code into your project

Code (CSharp):

1. private void OnCollisionEnter2D(Collision2D collision)
2.     {
3.         transform.position = _startPosition;
4.         _rigidbody2D.isKinematic = true;    
5.         Debug.Log("<color=red> OnCollisionEnter2D </color>")
6.     }

 

Omg how did I not see that

 

oh i forgot the I thanks for helping me figure this out!
