Question by CrowdedWorlds · Sep 29, 2011 at 05:29 PM · c#animationraycasttrigger

C# - Trigger Animation with Raycasting?

Short and sweet question this time! I'm trying to trigger an object hit with a ray cast to fire off an animation. From everything I understand the following should work

     void Update()
     {
     //Check if the E key is pressed`
     if (Input.GetKey("e"))
         {
         activatekey=1;
         RaycastHit hit;
         int scrx = Screen.width /2;
         int scry = Screen.height /2;
         Ray ray = Camera.main.ScreenPointToRay(new Vector2(scrx,scry));
         //Check if something is where our mouse is
         if(Physics.Raycast(ray, out hit, 1f))
             //Check if what we're hitting is the gameObject with a tag of "Food"
             if(hit.transform.gameObject.tag == ("Food"))
         {    
             hit.gameObject.animation["Take 001"].wrapMode = WrapMode.Once;
             hit.gameObject.animation.Play("Take 001");
             hit.transform.position = new Vector3 (Random.Range(0,1250),1,Random.Range(0,1950));

But clearly I don't understand because it yields this error

 Assets/GetFood.cs(31,37): error CS1061: Type `UnityEngine.RaycastHit' does not contain a definition for `gameObject' and no extension method `gameObject' of type `UnityEngine.RaycastHit' could be found (are you missing a using directive or an assembly reference?)

Any assistance of catching where this has broken down would be appreciated :)

simple.. you're calling hit.gameObject, and there is no 'gameObject' in RaycastHit. you need to access the collider first:

 hit.collider.gameObject
 hit.collider.transform
 etc...
