explain me the script
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[RequireComponent(typeof(Snake))]
public class SnakeController: MonoBehaviour {
public GameObject SnakePrefab;
public Snake head;
public Snake tail;
public int NESW;
public Vector2 nextPos;
void Start()
{
}
private void FixedUpdate()
{
Movement();
}
public void Movement()
{
GameObject temp;
nextPos = head.transform.position;
switch (NESW)
{
case 0:
nextPos = new Vector2(nextPos.x, nextPos.y + 1);
break;
case 1:
nextPos = new Vector2(nextPos.x + 1, nextPos.y);
break;
case 2:
nextPos = new Vector2(nextPos.x, nextPos.y - 1);
break;
case 3:
nextPos = new Vector2(nextPos.x - 1, nextPos.y);
break;
}
temp = (GameObject)Instantiate(SnakePrefab, nextPos, transform.rotation);
}
}
there are 2 scripts namely "snake" and "game controller". snake contains nothing. and the following script is "GameController". there are 4 things in the hierarchy. they are camera, directional light, a snake block and an empty gameobject namely "GameController". game controller script is attached to gamecontroller empty object. and snake script is attached to the snake. Please tell me why in the gamecontroller script we have made a var of script type? how does it benefit? Basically what is "public Snake head;"?
