Object flip on keypress

I want to make an object go to a certain rotation on a key press, but with the script I currently have it keeps repeating that function. Is there a way to make it stay in one rotation on a key press?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class SpriteFlipper : MonoBehaviour
6. {
7.  
8.  
9.     private void Update()
10.     {
11.  
12.         if (Input.GetKey(KeyCode.A) || Input.GetKey(KeyCode.LeftArrow))
13.         {
14.             transform.Rotate(0, 0, 90);
15.         }
16.         if (Input.GetKey(KeyCode.D) || Input.GetKey(KeyCode.RightArrow))
17.         {
18.             transform.Rotate(0,180,90);
19.         }
20.     }
21. }
22.  

 

Input.GeyKey() runs every frame. Try Input.GetKeyDown(), which only runs for one frame after the key is pressed.

 

Thank you! It worked!
