Random with Vector3.up

Question

Hello. My aim now is to use Random for choosing random Vector3 value, or rather Vector3.up\down\left\right. Example:

  if(timeleft < 0)
         {
             transform.Rotate(Vector3.left * Time.deltaTime * 30);  // here should be random value from left, right, up, down
             if(timeleft < -5)
             {
                 timeleft = 5f;
             }
         }

If I somehow can use Random.Range for playing random sound, I dont mind how it works with Vector3, please, help

Answer 1

Yeah, I solved it, just look at the result of my tries

     float timeleft;
     bool right = false;
     bool left = false;
 
     // Start is called before the first frame update
     void Start()
     {
         timeleft = 5f;
     }
 
     void Update()
     {
         if (Input.GetMouseButtonDown(0))
         {
 
             int randomPick = Random.Range(0, 2); //returns randomly 0,1.         
             switch (randomPick)
             {
                 case 0:
                     right = true;
                     break;
                 case 1:
                     left = true;
                     break;
                 default: break;
 
             }
         }
         if (right)
         {
             RotateRight();
         }
         if (left)
         {
             RotateLeft();
         }
         Debug.Log(timeleft);
     }
     void RotateRight()
     {
         transform.Rotate(Vector3.up * Time.deltaTime * 50);
         timeleft -= Time.deltaTime;
         if(timeleft < 0)
         {
             timeleft = 5f;
             right = false;
         }
     }
     void RotateLeft()
     {
         transform.Rotate(Vector3.down * Time.deltaTime * 50);
         timeleft -= Time.deltaTime;
         if (timeleft < 0)
         {
             timeleft = 5f;
             left = false;
         }
     }
 }

Random.Range simply returns a random number between the passed min and max parameters. Interestingly if you're passing floats, the max parameter is inclusive, but if you're passing integers the max parameter is exclusive.

Since you're using Vector3 shorthands you could try something like this:

 int randomPick = Random.Range(0,4); //returns randomly 0,1,2,3
 switch(randomPick){
 case 0:
 transform.Rotate(Vector3.left * Time.deltaTime * 30);
 break;
 case 1:
 transform.Rotate(Vector3.right* Time.deltaTime * 30);
 break;
 case 2:
 transform.Rotate(Vector3.up* Time.deltaTime * 30);
 break;
 case 3:
 transform.Rotate(Vector3.right* Time.deltaTime * 30);
 break;
 default: break;
 }

Yes, thanks atleast your advice gave a result. But your script just rotate item left\right\up\down every frame. My aim is to make script choose one side of these and rotate during another function made it stop. I think after choosing one of this cases, another ones should shut off. Heh, i bet my idea tells nothing, because im not a programmer at all, but I've tried.

It sounds like you're putting this code in the Update() function which is called every frame. Instead declare your own function to call whenever you want to rotate the object.

It rotates if I put this script not in every-frame function, but on very smal distance, it should rotate smoothly, so thats why it should be in every-frame function
