Question by unity_LAfgjMs60GPE7w · Apr 22, 2018 at 08:06 PM · c#javascriptkeyboardkeycodekeyboard input

Unity 2d select game object with keyboard

alt text alt text hey guys, I'm currently learning unity for a school project to build a game about space. The problem that I want to select the plants and align them with their orbit with the keyboard. this is my code and thanks.

pragma strict

var mercury = GameObject.FindWithTag ("mercury"); var venus = GameObject.FindWithTag ("venus"); function Start(){

} function Update () {

  if(Input.GetKeyDown(KeyCode.Escape)){
 
          mercury.gameObject.SendMessage("Activate");
          venus.gameObject.SendMessage("Desactivate");
      }
 
 if(Input.GetKeyDown(KeyCode.Space)){
          
          venus.gameObject.SendMessage("Activate");
          mercury.gameObject.SendMessage("Deactivate");
      }
 

} var inputEnabled : boolean = false;

// Update is called once per frame function mov () {

      if(inputEnabled == true){
          (Input.GetKeyDown(KeyCode.LeftArrow));{
          transform.Translate(Vector3(-1,0,0));}
          
      }
  
  }
 
  function Activate(){
      inputEnabled =true;
  }
 
  function Deactivate(){
      inputEnabled =false;

Be more specific. What problem are you encountering?

btw, in programming, you have to be very careful about spelling and typos, eg: "Desactivate"
