How do I know if my Raycast hit is a collider?

How do I check if raycast is hitting a gameobject?

  1. void Update () {
  2. Ray ray = Camera. main. ScreenPointToRay(Input. mousePosition);
  3. RaycastHit hit;
  4. if (Physics. Raycast(ray, out hit, 25)) {

How do you know if a Raycast hits an object in Unity?

Detect if Raycast hits a game object

  1. base. OnUpdate ();
  2. RaycastHit hit = new RaycastHit();
  3. Ray ray = new Ray(CachedTransform. position,transform.
  4. if (!_hit && _hitPrefab != null && Physics. Raycast (ray,out hit,_fireDistance)){
  5. SpawnHit(hit.
  6. _hit = true;
  7. // Echo the Raycast transform.
  8. Vector3 forward = transform.

How do you ignore a Raycast layer?

If you check the docs, Raycast() takes a LayerMask parameter called layerMask. The raycast will only happen against layerMask, so if you want to ignore a layer, you’d put in a layermask that contains all layers except for the one you want to ignore.

How do I get Raycast hit position in Unity?

Position of raycast hit

  1. function Update () {
  2. if (Input. GetButtonDown (“Fire1”)) {
  3. var ray : Ray = Camera. main. ScreenPointToRay (Input. mousePosition);
  4. if (Physics. Raycast (ray)) {
  5. // get the xyz position of the raycast hit and input into a var–
  6. //”posVar” for example.
  7. }
  8. }
