the raycast hits the collider of your object probably

KaelenOP•2y ago

How could I fix that? And how is it possible since that the object is the entry point ?

    private RaycastHit2D hitInfo;

    private GameObject grabbedObject;
    private int layerIndex;
    
    void Awake() {
        layerIndex = LayerMask.NameToLayer("Objects");
        hitInfo = Physics2D.Raycast(transform.position, -transform.right, 2f, layerIndex);
    }
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {     

     if (hitInfo.collider)
         {
            Debug.DrawRay(transform.position, -transform.right * 2f, Color.green);
            Debug.Log(hitInfo.collider.name);
            // //Prendre l'item
            // if (Keyboard.current.spaceKey.wasPressedThisFrame && grabbedObject == null)
            // {
            //     grabbedObject = hitInfoFridge.collider.gameObject;
            //     grabbedObject.GetComponent<Rigidbody2D>().isKinematic = true;
            //     grabbedObject.transform.position = grabPoint.position;
            //     grabbedObject.transform.SetParent(transform);
            // }

            // //Rel�cher l'objet
            // else if (Keyboard.current.spaceKey.wasPressedThisFrame)
            // {
            //     grabbedObject.GetComponent<Rigidbody2D>().isKinematic = false;
            //     grabbedObject.transform.SetParent(null);
    //         //     grabbedObject = null;
    //         // }
            
         } else {
            Debug.DrawRay(transform.position, transform.right * 2f, Color.red);
         }
     }
}

    private RaycastHit2D hitInfo;

    private GameObject grabbedObject;
    private int layerIndex;
    
    void Awake() {
        layerIndex = LayerMask.NameToLayer("Objects");

    }
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {     

     if (hitInfo.collider)
         {
            Debug.DrawRay(transform.position, -transform.right * 2f, Color.green);
            Debug.Log(hitInfo.collider.name);
            // //Prendre l'item
            // if (Keyboard.current.spaceKey.wasPressedThisFrame && grabbedObject == null)
            // {
            //     grabbedObject = hitInfoFridge.collider.gameObject;
            //     grabbedObject.GetComponent<Rigidbody2D>().isKinematic = true;
            //     grabbedObject.transform.position = grabPoint.position;
            //     grabbedObject.transform.SetParent(transform);
            // }

            // //Rel�cher l'objet
            // else if (Keyboard.current.spaceKey.wasPressedThisFrame)
            // {
            //     grabbedObject.GetComponent<Rigidbody2D>().isKinematic = false;
            //     grabbedObject.transform.SetParent(null);
    //         //     grabbedObject = null;
    //         // }
            
         } else {
            Debug.DrawRay(transform.position, transform.right * 2f, Color.red);
         }
     }
}

well if you shoot it from within the collider logically it would hit the collider colliders are volumes rather than surfaces

KaelenOP•2y ago

but I precised that only some layers should be triggered

Anton•2y ago

ah i see your error the raycast takes a layer mask not the layer index do a bitshift 1 << layerIndex I don't remember actually, you may need to invert it too ~(1 << layerIndex)

KaelenOP•2y ago

this one doesnt change anything this one set the drawray to red, but when I hit the layer that I want to target, it stay to red

Anton•2y ago

"it stay to red"? that's not english, can you word it differently?

KaelenOP•2y ago

sorry Im french the color of the layer is red even when I hit the layer in question

Anton•2y ago

so?

KaelenOP•2y ago

so the hit.collider always stays to null

Anton•2y ago

there's no code that would change it you probably meant to do the raycast in update awake only runs once

KaelenOP•2y ago

    private RaycastHit2D hitInfo;

    private GameObject grabbedObject;
    private int layerIndex;
    
    void Awake() {
        layerMask = LayerMask.GetMask("Objects");
        hitInfo = Physics2D.Raycast(transform.position, -transform.right, 2f, layerMask);
    }
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {     

     if (hitInfo.collider) // never set to true
         {
            Debug.DrawRay(transform.position, -transform.right * 2f, Color.green);
            Debug.Log(hitInfo.collider.name); // renvoie mon prefab, or c'est le poin d'entrée
            
            
         } else { 
            Debug.DrawRay(transform.position, transform.right * 2f, Color.red);
         }
     }
}

    private RaycastHit2D hitInfo;

    private GameObject grabbedObject;
    private int layerIndex;
    
    void Awake() {
        layerMask = LayerMask.GetMask("Objects");
        hitInfo = Physics2D.Raycast(transform.position, -transform.right, 2f, layerMask);
    }
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {     

     if (hitInfo.collider) // never set to true
         {
            Debug.DrawRay(transform.position, -transform.right * 2f, Color.green);
            Debug.Log(hitInfo.collider.name); // renvoie mon prefab, or c'est le poin d'entrée
            
            
         } else { 
            Debug.DrawRay(transform.position, transform.right * 2f, Color.red);
         }
     }
}

its a old code I change the layer index to the layer mask
