SOLVED. is if(Input.GetKeyDown(KeyCode.Alpha1)) what I wanted but I hasn't implementing this on a Monobehaviour class, that was the problem, although I'm using library UnityEngine and although the method that implementing this is called on a Update() from another class. thanks

Here is another Option if someone else runs into this.

 private KeyCode[] keyCodes = {
         KeyCode.Alpha1,
         KeyCode.Alpha2,
         KeyCode.Alpha3,
         KeyCode.Alpha4,
         KeyCode.Alpha5,
         KeyCode.Alpha6,
         KeyCode.Alpha7,
         KeyCode.Alpha8,
         KeyCode.Alpha9,
     };
 
 for(int i = 0 ; i < keyCodes.Length; i ++ ){
   if(Input.GetKeyDown(keyCodes[i])){
          int numberPressed = i+1;
          Debug.Log(numberPressed);
   }
 
 // WUCC check for errors. 
 }

I hadn't thought of this nice, extensible way. Thank you!

Also, $$anonymous$$eyCode.Alpha0 should be included.

How about KeyCode.

  Alpha0   The '0' key on the top of the alphanumeric keyboard.
 Alpha1     The '1' key on the top of the alphanumeric keyboard.
 Alpha2     The '2' key on the top of the alphanumeric keyboard.
 Alpha3     The '3' key on the top of the alphanumeric keyboard.
 Alpha4     The '4' key on the top of the alphanumeric keyboard.
 Alpha5     The '5' key on the top of the alphanumeric keyboard.
 Alpha6     The '6' key on the top of the alphanumeric keyboard.
 Alpha7     The '7' key on the top of the alphanumeric keyboard.
 Alpha8     The '8' key on the top of the alphanumeric keyboard.
 Alpha9     The '9' key on the top of the alphanumeric keyboard.

next time take a look at the reference material first before asking on UA

I saw that material and tested all the possibilities. with $$anonymous$$eyCode.Alpha I also don't get numerical keys. I'm testing as follows:

         if(Input.Get$$anonymous$$eyDown($$anonymous$$eyCode.$$anonymous$$eypad1))
             Debug.Log ("keypad...");
         
         if(Input.Get$$anonymous$$eyDown($$anonymous$$eyCode.JoystickButton1))
             Debug.Log ("joystick...");
         
         if(Input.Get$$anonymous$$eyDown($$anonymous$$eyCode.Alpha1))
             Debug.Log ("alpha1...");

and it don't show me anything

odd. you are checking for Input inside your Update function?

I see no reason for those calls you have shown not to work for keyboard/joystick input. Is this being run in the editor?

For future reference,

Here's an alternative to detect keycodes 0-9, avoiding a block of if statements or setting up enums/arrays and forloops!

 Using System;
 if(Input.inputString != ""){
     int number;
     bool is_a_number = Int32.TryParse(Input.inputString, out number);
     if (is_a_number && number >= 0 && number < 10){
         // do some work
     }
 }
