Je suis sur un project de FPS

J'ai ajouté un sniper et je voudrais afficher la distance de mon ennemi quand je zoom dessus.

Connaissez vous un script qui le permettrais?

Merci

English

I would advise to use Raycasting

 public new Camera camera ; // Drag & drop the camera of your scene here
 
 private void Start()
 {
     // The following lines make sure there is a camera if none has been specified
     if( camera == null )
         camera = Camera.main ;
     if( camera == null )
         camera = FindObjectOfType<Camera>();
 }
 
 public float GetDistanceFromTarget()
 {
     // Cast a ray from the center of the screen
     Ray ray = camera.ViewportPointToRay( new Vector3(0.5f, 0.5f, 0) );
     RaycastHit $$anonymous$$t;
     if (Physics.Raycast(ray, out $$anonymous$$t))
         return $$anonymous$$t.distance ;
     else
         return Mathf.Infinity;
     // or shorter version :
     // return Physics.Raycast(ray, out $$anonymous$$t) ? $$anonymous$$t.distance : Mathf.Infinity ;
 }

If you want t$$anonymous$$s method to work, your ennemies and the elements in your scene must have a collider.

L'utilisation de la technique de Raycasting me semble la plus appropriée

 public new Camera camera ; // Glisser et déposer la caméra de la scène dans l'inspecteur
 
 private void Start()
 {
     // Les lignes suivantes permettent de récupérer une caméra dans la scène si aucune n'a été spécifiée
     if( camera == null )
         camera = Camera.main ;
     if( camera == null )
         camera = FindObjectOfType<Camera>();
 }
 
 public float GetDistanceFromTarget()
 {
     // Lancer de rayon depuis le centre de l'écran
     Ray ray = camera.ViewportPointToRay( new Vector3(0.5f, 0.5f, 0) );
     RaycastHit $$anonymous$$t;
     if (Physics.Raycast(ray, out $$anonymous$$t))
         return $$anonymous$$t.distance ;
     else
         return Mathf.Infinity;
     // Version plus concise :
     // return Physics.Raycast(ray, out $$anonymous$$t) ? $$anonymous$$t.distance : Mathf.Infinity ;
 }

Évidemment, pour que cette technique marche, il sera nécessaire que les ennemis (et les éléments de décor) soient munis d'une boite de collision.

Are you trying to zoom in on the enemy? If so, you would do somet$$anonymous$$ng like t$$anonymous$$s.

 public Camera playerCamera; 
 private bool isZoomed = false; 
 
 void Start() {
 playerCam camera = GetComponent<fieldOfView>(); 
 }
 
 void Update () {
        if (Input.GetButtonDown("FIre2")) {
                 isZoomed = !isZoomed; 
                 playerCam = 40; 
                 
        }
 }

If t$$anonymous$$s does not work try doing the "Snipe scope effect" video on YouTube by brackeys.
