so I am copying this exact tutorial on how to code pacman
http://noobtuts.com/unity/2d-pacman-game
currently on The Movement Scriptand type the code as it shows on the website.
the code seems to work but when ever i use the arrow keys it doesnt want to do anything.
Heres my code:
using UnityEngine;
using System.Collections;
public class PacmanMove : MonoBehaviour {
public float speed = 0.4f;
Vector2 dest = Vector2.zero;
void Start() {
dest = transform.position;
}
void FixedUpdate() {
// Move closer to Destination
Vector2 p = Vector2.MoveTowards(transform.position, dest, speed);
rigidbody2D.MovePosition(p);
// Check for Input if not moving
if ((Vector2)transform.position == dest) {
if (Input.GetKey(KeyCode.UpArrow) && valid(Vector2.up))
dest = (Vector2)transform.position + Vector2.up;
if (Input.GetKey(KeyCode.RightArrow) && valid(Vector2.right))
dest = (Vector2)transform.position + Vector2.right;
if (Input.GetKey(KeyCode.DownArrow) && valid(-Vector2.up))
dest = (Vector2)transform.position - Vector2.up;
if (Input.GetKey(KeyCode.LeftArrow) && valid(-Vector2.right))
dest = (Vector2)transform.position - Vector2.right;
}
}
bool valid(Vector2 dir) {
// Cast Line from 'next to Pac-Man' to 'Pac-Man'
Vector2 pos = transform.position;
RaycastHit2D hit = Physics2D.Linecast(pos + dir, pos);
return (hit.collider == collider2D);
}
}
If you could help me that would great!
