场景生成：

 

var mapAsset : TextAsset;
var blockPrefab : Transform;
var pelletPrefab : Transform;
var superPrefab : Transform;

// 25 rows,     38 columns

function Awake () {
    var map = mapAsset.text.Split ("\n"[0]);
    var v = new Vector3 ();
    v.y = 1.0;
    var j_off = map.length / 2.0;                       // j_off:   12.5
    
    // test
    print("length:"+map.length);
    print("j_off:"+j_off);
    
    for (var j = 0; j < map.length; j ++) 
    {
        v.z = (map.length - j - j_off - 1) * 2;
        var i_off = map[j].length / 2.0;               // i_off:   19
        
        // test
        print("i_off: "+i_off);
        
        for (var i = 0; i < map[j].length; i ++) 
        {
            v.x = (i - i_off) * 2 + 1;
            
            if (map[j][i] == "X") 
            {
                var inst = Instantiate (blockPrefab, v, Quaternion.identity);
                inst.transform.parent = transform;     
                // test
                //print(v + ": X");
            } 
            else if (map[j][i] == ".") 
            {
                Instantiate (pelletPrefab, v, Quaternion.identity);
                // test
                //print(v + ": .");
            } 
            else if (map[j][i] == "O") 
            {
                Instantiate (superPrefab, v, Quaternion.identity);
                // test
                //print(v + ": O");
            }
        }
    }
}

 

豆子被吃掉：

 

var scoreDisplay : GUIText;
var smallPelletScore = 10;       // 小豆子得分 10
var superPelletScore = 100;    // 大豆子得分 100
private var score = 0;
 
function Update () 
{
    scoreDisplay.text = "Score: " + score;
} 

function OnTriggerEnter (other : Collider) 
{
    if (other.name == "BasicPellet(Clone)") 
        score += smallPelletScore;
    else if (other.name == "SuperPellet(Clone)")
        score += superPelletScore;
    Destroy (other.gameObject);
}

 

豆子的移动策略：

 

var howLong = 1.0;
var howFast = 8.0;
private var nextUpdate = 0.0;
privatevar direction : Vector3;

function Update () 
{
    if (Time.time > nextUpdate) 
    {
        nextUpdate = Time.time + (Random.value * howLong);
        direction = Random.onUnitSphere;    // 产生一个随机的点  Vector3 类型
        direction.y = 0;
        direction.Normalize ();    // 单位化，模为 1，即长度为 1
        direction *= howFast;
        direction.y = 1.5 - transform.position.y;
    }

    var controller = GetComponent(CharacterController);
    controller.Move(direction * Time.deltaTime);  // deltaTime：以秒计算，完成最后一帧的时间（只读）。
