Using a Switch/Case statement for movement

Hello everybody!

I am currently a newbie to programming and Unity itself (kinda learning both at the same time, as I started finding building console applications are getting extremely boring).

My question is, In order to move a character in a 2D environment, I started out using if statements, and it worked perfectly fine. Although, instead of a bunch of if statements, i want to use switch/case.

problem is: i get a ton of errors.

The code is below:

Code (CSharp):

1.    
2. public class Character : MonoBehaviour {
3.  
4.     float fMoveSpeed = 0.1f;
5.     //float fJumpHeight = 5.0;
6.  
7.     void DoMovement()
8.     {
9.         switch (Input.GetKey) {
10.         case KeyCode.D:
11.             transform.Translate (new Vector3 (fMoveSpeed, 0, 0));
12.             break;
13.         case KeyCode.A:
14.             transform.Translate (new Vector3 (-fMoveSpeed, 0, 0));
15.             break;
16.         }
17.     }
18.  

Could anybody help?

 

why not use Input.GetAxis("Horizontal")

 

Errors are??

 

Right now, I'm just on a learning phase with my programming. I'm actually learning with C++ but I could not find a another engine that's easy enough for me to script and learn in C++, so I'm giving Unity a try . Cause of that, I'm not familiar with all the Unity functions yet lol.

The errors are:
Error CS0151: A value of an integral type expected (CS0151) (Assembly-CSharp)
Error CS0029: Cannot implicitly convert type 'UnityEngine.KeyCode' to 'method group' (CS0029) (Assembly-CSharp)
Error CS0029: Cannot implicitly convert type 'UnityEngine.KeyCode' to 'method group' (CS0029) (Assembly-CSharp)

I am also calling my function in the Update, so I'm guessing its not that?

 

GetKey is a function, not a property. You can't use it with a switch (I mean, if you use it, you will have only two cases because it returns an boolean).

 

Thanks for the reply .

Would using a switch/case not be a good idea for character movements?

It works perfectly fine with if statements, I just wanna see if its possible with a switch/case?

 

You shouldn't. With a if statement, you're checking if the returning value is TRUE or not. If we had an array of active keys, a switch could have been a good idea, but we don't.

I don't really like switch ; I prefer use if statements and if there are too many "if / else if", maybe I did something wrong so I check for another solution.

But you usually use switch when you want to enumerate something.. like an ENUM or an INTEGER :

Code (CSharp):

1.         public enum myEnum {
2.             NONE,
3.             SHOOT,
4.             MOVE,
5.             JUMP
6.         }
7.  
8.         public void checkEnum() {
9.             switch (playerState) {
10.                 case myEnum.SHOOT:
11.                     break;
12.                 case myEnum.MOVE:
13.                     break;
14.                 case myEnum.JUMP:
15.                     break;
16.                 default:
17.                     break;
18.             }
19.         }

 

how do i make a w a s d movement controls with switch
