Terrain - Detect collision coordinates?

Questions & Answers

Hi, I’m making a game where as things collide with the ground (a Terrain object) the floor is coloured. I have made a class where I can paint specific coordinates on the Terrain, however I don’t know how to get the coordinates where the object hits the Terrain. Does anyone know a way to do this?

Look here: Unity - Scripting API: Collider.OnCollisionEnter(Collision)
The contact point is the thing you are looking for.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
	
	
    void OnCollisionEnter(Collision collision) {
        foreach (ContactPoint contact in collision.contacts) {
            Debug.DrawRay(contact.point, contact.normal, Color.white);
        }
        
        
    }
}
