Double Spawn

I am using the below code to spawn a crashed item on collision. Sometimes, not always, I get a double spawn of the crashed vehicle. The player container is holding the normal vehicle.

Code (CSharp):

1. using System.Collections;
2. using UnityEngine;
3. using UnityEngine.SceneManagement;
4.  
5. public class CrashedSleigh : MonoBehaviour
6. {
7.     public GameObject crashedSleigh;
8.     public GameObject playerContainer;
9.  
10.     void OnCollisionEnter(Collision collisioninfo)
11.     {
12.         if (collisioninfo.collider.tag == "Obstacle")
13.         {
14.             Instantiate(crashedSleigh, transform.position, transform.rotation);
15.             Destroy(playerContainer);
16.         }
17.  
18.        
19.     }
20. }

 

I think you can hit more than one collider in a given frame... is that it?

You can print out the name of the collider you hit at the start of the method... it is in

collisioninfo

 

I will try that. Its very random, I was playing last night testing something else and hit one of my trees with a single collider and it spawned three. It was quite amusing but not what Im looking for.

 

And that's why we're all in gamedev.

One other obvious thought is: doublecheck you didn't stick this in two places on your object, one that is on a collider that is harder to hit, that you didn't originally intend it to be. I find physics collisions are almost always explainable once you start printing out the names of who was involved.

"Oh, I was hitting the monster's left toenail... no wonder I died..."
