Why does my Raycast stop detecting colliders
When the game is first ran the raycast will pick up the collider however it will just stop at random ive tried 2 differnt ways of doing it and nothing has fixed it any help would be nice.
Could you share the code? might be greatly useful to see what you're doing
yey, OK well Imma leave that to someone else I've not used ray casters for at least a year.
Physics.Raycast stops as soon as it hits a single collider. If you want the ray to not stop and return more than a single hit, use Physics.RaycastAll instead. Then iterate through the collection it returns and check for what you need there.
Here's a sample based on what you provided:
using System.Linq;
using UnityEngine;
public class TestScript : MonoBehaviour
{
private void FixedUpdate()
{
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit[] hits = Physics.RaycastAll(ray, Mathf.Infinity);
if (hits.Any(x => x.collider.tag == "Unit"))
{
Debug.Log("Bang");
}
}
}
Also an extra note regarding the Physics.Raycast. It returns a boolean. If you want to access the object the raycast found. Use the hit variable (example: hit.collider.gameObject).
using System.Collections; using System.Collections.Generic; using UnityEngine;
public class test : MonoBehaviour { public List Highlit; public List Selected;
private Transform Sunit;
private GameObject Curtuse;
public Material highlit;
public Material selc;
public Material unSelec;
private bool high;
private RaycastHit hit;
// Start is called before the first frame update
void Start()
{
high = false;
Highlit = new List<GameObject>();
Selected = new List<GameObject>();
}
// Update is called once per frame#
void FixedUpdate(){
Ray r = Camera.main.ScreenPointToRay(Input.mousePosition);
//RaycastHit hit;
LayerMask m = ~8;
if (Physics.Raycast(r ,out hit, Mathf.Infinity) == GameObject.FindGameObjectWithTag("unit")){
Debug.Log("Bang");
}
}
void Update()
{
if(hit.collider.tag =="unit"){
Curtuse = hit.collider.gameObject;
if(Highlit.Contains(Curtuse)){
Curtuse.GetComponent<MeshRenderer> ().material = highlit;
}
if (Highlit.Contains(Curtuse) == false){
Highlit.Add(Curtuse);
}
}
else
{
foreach(GameObject obj in Highlit){
Curtuse.GetComponent<MeshRenderer> ().material = unSelec;
Debug.Log("hit floor");
}
Highlit.Clear();
}
} }
