Question by NAYIR55IndieDev · Apr 24, 2018 at 01:09 AM · rotationrotate objectkeypress

How to make a gameobject rotate coninously on key press?

I'm working on a little project and I want to make a gameobject rotate continously after pressing a key, I did something basic with transform.Rotate(), but I have to press the key or hold it for the gameobject to rotate, here's the script

 void Update () 
     {
         StartTurntableKey();
     }
 
     public void StartTurntableKey()
     {
         if (Input.GetKeyDown(KeyCode.I))
         {
             turntable.transform.Rotate(Vector3.up * turnSpeed * Time.deltaTime);
         }
     }

The code is fine (or at least it looks like it is), it supposed to start the rotation, but I have to press the key every frame to rotate...

Any suggestion? Any tip, or snippet to share?

Thanks

Sounds like you just need a variable to store whether your turntable is rotating or not. Try this on for size:

 private bool isRotating;
 
 void Update() 
 {
     StartTurntableKey();
 }
 
 public void StartTurntableKey()
 {
     if (Input.GetKeyDown(KeyCode.I))
     {
         isRotating = true;
     }
     else if(Input.GetKeyDown(KeyCode.O))
     {
         isRotating = false;
     }
 
     if(isRotating)
     {
         turntable.transform.Rotate(Vector3.up * turnSpeed * Time.deltaTime);
     }
 }

I mapped "stop rotating" to the "O" key but you can map it to whatever you like.
