2D Top Down Character Controller

Questions & Answers
1

I am trying to make a top down 2D game, sort of in the style of classic Zelda, at least the movement. Thats all i need to start moving on and ive been stuck looking for help on this for days now. I know its so simple, but i cant seem to figure it out. This is what i have, i just copied the movement up and pasted it 3 times because i figured it would be same just different vector. But I dont know what i need to put in its place for the other directions. Please help!!

#pragma strict

 //Inspector Variables
 var playerSpeed : float = 10; //speed player moves
 
 function Update () 
 {
 
     MoveForward(); // Player Movement 
 }
 
 function MoveForward()
 {
 
     if(Input.GetKey("up"))//Press up arrow key to move forward on the Y AXIS
     {
         transform.Translate(0,playerSpeed * Time.deltaTime,0);
     }
     if(Input.GetKey("up"))//Press up arrow key to move forward on the Y AXIS
     {
         transform.Translate(0,playerSpeed * Time.deltaTime,0);
     }
     if(Input.GetKey("up"))//Press up arrow key to move forward on the Y AXIS
     {
         transform.Translate(0,playerSpeed * Time.deltaTime,0);
     }
     if(Input.GetKey("up"))//Press up arrow key to move forward on the Y AXIS
     {
         transform.Translate(0,playerSpeed * Time.deltaTime,0);
     }
 }

Hi,

that should do it. You needed just to change the values in the Translate() method to the specific direction.

#pragma strict

//Inspector Variables
  var playerSpeed : float = 10; //speed player moves
  
  function Update () 
  {
  
      MoveForward(); // Player Movement 
  }
  
  function MoveForward()
  {
  
      if(Input.GetKey("up"))//Press up arrow key to move forward on the Y AXIS
      {
          transform.Translate(0,playerSpeed * Time.deltaTime,0);
      }
      if(Input.GetKey("down"))//Press up arrow key to move forward on the Y AXIS
      {
          transform.Translate(0,-playerSpeed * Time.deltaTime,0);
      }
      if(Input.GetKey("left"))//Press up arrow key to move forward on the Y AXIS
      {
          transform.Translate(-playerSpeed * Time.deltaTime,0 ,0);
      }
      if(Input.GetKey("right"))//Press up arrow key to move forward on the Y AXIS
      {
          transform.Translate(playerSpeed * Time.deltaTime,0 ,0);
      }
  }

A good start how to make 2D games is the following tutorial. You can easily change the script in the video to make a top down character moving.
