Which is the best way to detect colliders between 2 objects in unity?

I need to know if between me and a tile on the map there is a particular object, so i should make a line starting from me to the target object. The problem is that i need only the objects that intersect this line.

 

Did you try Physics.Raycast.

 

is this what you try to do?

 

yes

 

Physics.RaycastAll will detect all the objects that intersect with the line.
https://docs.unity3d.com/ScriptReference/Physics.RaycastAll.html

1. do you know how to set up Physic Layer?
2. do you need help how to use Physics.RaycastAll?

 

Code (CSharp):

1. public class SampleClass : MonoBehaviour
2.     {
3.         public Transform m_target;
4. //mask of an object that can get hit by ray
5.         public LayerMask m_mask;
6.  
7.         void Update()
8.         {
9.  
10.             //Calculate the direction where the target is in worldspace
11.             Vector3 direction = m_target.position - transform.position;
12.             //find out the distance between you and the target
13.             float distance = Vector3.Distance(transform.position, m_target.position);
14.  
15.             RaycastHit[] hits; // all Objects that are on top the line will listed here temporarily, you can create some manager to keep track these data
16.             hits = Physics.RaycastAll(transform.position, direction, distance, m_mask);
17.  
18.             for (int i = 0; i < hits.Length; i++)
19.             {
20.                 RaycastHit hit = hits[i];
21.  
22.                 Debug.Log(hit.transform.gameObject.name);
23.             }
24.         }
25.     }
26.  
27. //this is basic modify as you like

 

thanks
