How do I stop the constant rotation from the same key?

Hey everyone, so I am currently building a Roguelike style game for a college project; and an issue popped up to do with the looking around of my player (as I intend using WASD for movement and the ARROW keys for shooting - inspired by The Binding of Isaac.

Here is the code that I got for the rotation of my player:

Code (CSharp):

1. public class RotateAround : MonoBehaviour {
2.  
3.     public Transform pointOfRotation;
4.     // public float RotSpeed = 5f;
5.  
6.  
7.     void Update()
8.     {
9.         if(Input.GetKeyDown(KeyCode.UpArrow))
10.             {
11.             transform.RotateAround (pointOfRotation.transform.position, Vector3.forward, 90);
12.  
13.             }
14.         if(Input.GetKeyDown(KeyCode.DownArrow))
15.         {
16.             transform.RotateAround (pointOfRotation.transform.position, Vector3.forward, 90);
17.  
18.         }
19.         if(Input.GetKeyDown(KeyCode.RightArrow))
20.         {
21.             transform.RotateAround (pointOfRotation.transform.position, Vector3.forward, 90);
22.  
23.         }
24.         if(Input.GetKeyDown(KeyCode.LeftArrow))
25.         {
26.             transform.RotateAround (pointOfRotation.transform.position, Vector3.forward, 90);
27.  
28.         }
29.  
30.        
31.  
32.     }
33. }

What I aim for the code to do, is when I press the Up Arrow I want the player to look up but when I press it again I want it to stay looking up (it is currently moving an extra 90 degrees than it should be). I was thinking about messing about with a LookAt() function but I don't know if that is the correct function to use.

P.S. I aim to have the object I want to rotate around the pivot in the middle of the player.

 

You could add 4 booleans to each of the directions

Code (CSharp):

1. public class RotateAround : MonoBehaviour {
2.     public Transform pointOfRotation;
3.     // public float RotSpeed = 5f;
4.  
5. private bool up = false;
6. private bool left = false;
7.  
8. private bool right = false;
9.  
10. private bool down = false;
11.     void Update()
12.     {
13.         if(Input.GetKeyDown(KeyCode.UpArrow) && up = true)
14.             {
15.            
16. up = true;
17. down = flase;
18. left = false;
19. right = false;
20.  
21. transform.RotateAround (pointOfRotation.transform.position, Vector3.forward, 90);
22.             }
23.         if(Input.GetKeyDown(KeyCode.DownArrow))
24.         {
25.             transform.RotateAround (pointOfRotation.transform.position, Vector3.forward, 90);
26.         }
27.         if(Input.GetKeyDown(KeyCode.RightArrow))
28.         {
29.             transform.RotateAround (pointOfRotation.transform.position, Vector3.forward, 90);
30.         }
31.         if(Input.GetKeyDown(KeyCode.LeftArrow))
32.         {
33.             transform.RotateAround (pointOfRotation.transform.position, Vector3.forward, 90);
34.         }
35.      
36.     }
37. }

 

Ooooo I completely messed up the title, I meant to say "How do I stop the constant rotation using the same key?" oops!

 

thats cause i say, if there is a boolean there, it wont activate the same twice

 

Booleans won't work as I am updating it every frame meaning it will rotate every 90 degrees (which is what I don't want it to do)

 

boolean works always

Code (CSharp):

1. //dont execute if bool is true
2. if(Input.GetKeyDown(KeyCode.UpArrow) &&  !up)
3.             {
4.        
5. up = true;
6. down = flase;
7. left = false;
8. right = false;

I would, perhaps, use transform.up (right, -up,...)

Code (CSharp):

1.  if(Input.GetKeyDown(KeyCode.UpArrow))
2.             {
3.             transform.up = Vector3.up;
4.             //depended where is the forward from the sprite
5.             //it can be transform.right = Vector3.up;
6.             }

 

How do I apply movement to the transform example? As it only rotates on a single point, not around the rotation point like what the "transform.RotateAround" does, feeling on giving up this style of controls but giving it one more try.

 

I would go for either LookAt or RotateTowards.

 

sorry, I didn't have seen that you are using transform.RotateAround, thought about sprite with 4 directions.

 

Figuring out how to use RotateTowards() but I don't really understand it, is there a proper way into setting it up?
