How to make collision between 2 objects?

Hello,
With friend, we create a ittle game where you control a boat and you must avoid stone, but we don't understand how we can detect the collision and make losse the game?

I upload screenshot of these two object (boat and stone) we work on 5.0.2f3

 

If you have colliders of the same type (2d/3d) on both objects, they should collide fine.

Then you have access to OnCollisionEnter / OnCollisionEnter2D, this is where you can detect what hit your player.

eg.

Code (CSharp):

1. void OnCollisionEnter2D(Collision2D col){
2. Debug.log("Collided with " + col.gameObject.name);
3.  
4. }

 

Take time to do the tutorials in the learn section linked at the top. They will explain how to use colliders & triggers. After you complete each one start a new project & try to do it on your own to highlight the bits you need for revision. Then try to add something to the game or change bits to see what effects they have. This is the best way to learn.

 

It's for school, it's a "game of entreprise" and we need to make communication so we create website, audio adds, and a game but we only have 2days
