Question

Before I start I should mention I am a unity noob.

So I have been following a pong tutorial,but I have a problem. The rackets are not moving when you press the arrow. If you know how to fix this please let me know

My code:

using UnityEngine;
using System.Collections;

public class MoveRacket : MonoBehaviour {
// up and down keys (to be set in the Inspector)
public KeyCode up;
public KeyCode down;

void FixedUpdate () {
    // up key pressed?
    if (Input.GetKey(up)) {
        transform.Translate(new Vector2(0.0f, 0.1f));
    }

    // down key pressed?
    if (Input.GetKey(down)) {
        transform.Translate(new Vector2(0.0f, -0.1f));
    }
}
}

and the control picking option:

Answer 1

You said it doesn't move when you press the arrow. According to your key code assignments, you should press W or S .

Answer 2

just change the name of your method FxedUpdate() to Update()

using UnityEngine;
using System.Collections;

public class MoveRacket : MonoBehaviour {
// up and down keys (to be set in the Inspector)
public KeyCode up;
public KeyCode down;

void Update () {
// up key pressed?
if (Input.GetKey(up)) {
    transform.Translate(new Vector2(0.0f, 0.1f));
}

// down key pressed?
if (Input.GetKey(down)) {
    transform.Translate(new Vector2(0.0f, -0.1f));
}
}
}

Answer 3

The real solution so that you don't make mistakes in the Unity Editor .

void FixUodate()
{
    if(Input.GetKey(KeyCode.UpArrow))  
       transform.Translate(new Vector2(0.0f, 0.1f));


    else if (Input.GetKey(KeyCode.DownArrow))  
      transform.Translate(new Vector2(0.0f, -0.1f));
}
