How do you know if Raycast hits something?

Check if the raycast hit something on the way

1. Vector3 mousePos = Camera. main.
2. Debug. DrawLine(player.
3. if (Input. GetMouseButtonDown (0)) {
4. RaycastHit2D rayCast = Physics2D. Raycast(mousePos, Vector2.
5. if(rayCast. collider == null) {
6. player. position = new Vector3(mousePos.
7. } else {
8. Debug.

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)) {
5. if(hit. collider. gameObject. layer == 8 && hit. collider != null) {
6. actionMenu = true;

8. }

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. }
