Question by shdwcythe · Mar 29, 2014 at 11:48 AM · c#rotatearoundsword

RotateAround a player

I am working on making a zelda-type game, and i am trying to make a script to make the sword swing. I am using the transform.RotateAround function, and I can't get it to work. Nothing happens. It deletes the sword clone after 1 second, but nothing happens before that, I don't even see the object appear in my game window, when it does in the hierarchy.

 void Update () {
         if(Input.GetKeyDown("x")){
             var P = (GameObject)Instantiate(sword,transform.position,Quaternion.identity);
             P.transform.parent = transform;
             // Spin the object around the world origin at 20 degrees/second.
             transform.RotateAround(transform.position, Vector3.up, -180);
             // Destroys the swords created after one second
             // of creation, in order of creation
             GameObject[] killEmAll;
                killEmAll = GameObject.FindGameObjectsWithTag("Sword");
             for(int i = 0; i < killEmAll.Length; i++){
                 Destroy(killEmAll[i].gameObject, 1);
             }
         }
             
     }
 }

you are rotating player as i can understand from the code, you should rotate p.transform, not transform.

Also rotation is not being done over time, it will be a single flip (sort of). you can add a counter or use invoke function to see its rotation.

How do I do that? I tried changing it to transform.RotateAround(transform.position, Vector3.zero, -180, 1); and it gave me an error.

you should rotate P which is the sword. also multiply rotation speed by the time the frame took to render (Time.deltaTime) it should look something like this:

 P.transform.RotateAround(transform.position, Vector3.up, 20*Time.deltaTime);
