how to use input While holding a key

so i have this rotate script but instead of rotating while holding a key, it rotates 3 units to the left or right when i press a key:

Code (CSharp):

1.  void Update()
2.     {
3.         if (Input.GetKeyDown(KeyCode.A))
4.         {
5.             transform.Rotate(new Vector3(0f, 0f, 2f));
6.         }
7.  
8.         if (Input.GetKeyDown(KeyCode.D))
9.         {
10.             transform.Rotate(new Vector3(0f, 0f, -2f));
11.         }
12.  
13.     }

 

GetKeyDown (and GetKeyUp for that matter) has an internal limiter that prevents it from registering again until the key has been released. To keep registering the key you need to use GetKey.

https://docs.unity3d.com/ScriptReference/Input.GetKey.html

Code (csharp):

1. void Update()
2. {
3.         if (Input.GetKey(KeyCode.A))
4.         {
5.             transform.Rotate(new Vector3(0f, 0f, 2f));
6.         }
7.  
8.         if (Input.GetKey(KeyCode.D))
9.         {
10.             transform.Rotate(new Vector3(0f, 0f, -2f));
11.         }
12. }

 

Thanks this worked!
