2D坦克大战

1.Player预制体

添加BoxCollider2D RigidBody2D Gravity Scale=0

移动转向：移动 transform.Translate(Vector.方向*速度*Time.fixdDeltaTime,Space.World);

转向通过改变SpriteRender的Soprite属性。SpriteRender sr=GetComponent<SpriteRender>();

public Sprite[] TankSprite; if(h>0) sr.Sprite=tankSprite[]; bullectEulerAngles = new Vector3(0, 0, 90);

攻击：if((Input.GetKeyDown(Keycode.Space)) private Vector3 bullectEulerAngles;

Instantiae(bulletPrefab,transform.position,Quaternion.Eular(transform.eulerAngles+bullectEulerAngles));

攻击CD：private float timeAttack =0.4f ;

FixedUpdate() 固定物理帧 { Move(); if(timeAttack==0.4){ Attack() ;}else { timeAttack+= Time.fixedDeltaTime; } }

无敌3s：private bool isDefended = true; Update()=>if(isDefende) defendPrefab.SetActive=ture;

private bool isDefended = true; defendTime -= Time.deltaTime; isDefended = false;
defendPrefab.SetActive(false);

死亡： Die()=>if (isDefended) return; Instantiate(explosionPrefab, transform.position, transform.rotation);

Destroy(gameObject); PlayerManager._instance.isDead = true;

2.子弹预制体

添加BoxCollider2D ,RigidBody2D Gravity Scale=0; public bool isPlayerBullect;

移动：transform.Translate(transform.up* moveSpeed * Time.deltaTime, Space.World);

碰撞：Switch(collision.tag)=> Case "Tank": if(!isPlayerBullect)=>collision.SendMessage("Die");Destory;

Case "Enemy": if(isPlayerBullet)=>collision.SendMessage("Die").Destory(); ... ... ... ... ... ...

3.敌人AI

随机移动：private float changDir=3，float v， h=-1;

if(changDir>=3)=>int num = Random.Range(0, 8);

=>if(num>5)=>v=-1;h=0; ... ... ... ... changDir=0; else=> changDir+=Time.DealtTime;

移动转向和Player一样。

自动攻击：取消Input.GetKeyDown 同Player。

死亡：同Player。PlayerManager.Instance.Score++;

4.PlayerManager

public static PlayerManager Instance;

public bool isDead; //玩家死亡 public int lifeValue = 3; //生命
public bool isDefeat; //游戏结束 public int playScore = 0; //得分

复活：private void Recover()=>if(lifeValue<=0) isDefeat=true; Invoke("ReturnMain",2);

else=>lifeValue--; GameObject go = Instantiate(born, new Vector3(-2, -8, 0), Quaternion.identity);
go.GetComponent<Born>().createPlayer = transform; isDead = false;

Update()=> if(isDefeat)=>Invoke("ReturnMain",2);return; if(isDead)=>Recover(); hp.text=lifeValue.ToString();

5.随机生成地图

public GameObject[ ] item; //初始化地图数组 //0 老家 //1 墙 //2 障碍 //3 出生 //4河流 //5 草 // 空气墙

private List<Vector3> itemPos = new List<Vector3>();

实例化方法 Void CreateItem(GameObject createGame, Vector3 pos, Quaternion quaternion)

=>GameObject itmeGo = Instantiate(createGame, pos, quaternion);

itmeGo.transform.SetParent(gameObject.transform);

itemPos.Add(pos);

判断该位置是否存在列表中

private bool HasThePos(Vector3 createPos) {

for (int i = 0; i < itemPos.Count; i++) {

if (createPos == itemPos[i]) {

return true;

return false;

}

随机产生位置
    private Vector3 CreateRandomPos() {
        while (true) {
            Vector3 createPosition = new Vector3(Random.Range(-9, 10), Random.Range(-7, 8), 0);

            if (!HasThePos(createPosition)) {
                return createPosition；
    }

    //敌人随机位置
    private void CreateEnemy() {
        int num = Random.Range(0, 3);
        Vector3 enemyPos = new Vector3();
        if (num == 0)
enemyPos = new Vector3(-10, 8, 0);
        CreateItem(item[3], enemyPos, Quaternion.identity);
    }

Awake(){

   //家
        CreateItem(item[0],new Vector3(0,-8,0),Quaternion.identity);
        CreateItem(item[1], new Vector3(-1, -8, 0), Quaternion.identity);
        CreateItem(item[1], new Vector3(1, -8, 0), Quaternion.identity);
        for (int i = -1; i < 2; i++)
            CreateItem(item[1], new Vector3(i, -7, 0), Quaternion.identity);

        //玩家
        GameObject go = Instantiate(item[3], new Vector3(-2, -8, 0), Quaternion.identity);
        go.GetComponent<Born>().createPlayer = true;

        //敌人
        CreateItem(item[3], new Vector3(-10, 8, 0), Quaternion.identity);
        CreateItem(item[3], new Vector3(0, 8, 0), Quaternion.identity);
        CreateItem(item[3], new Vector3(10, 8, 0), Quaternion.identity);
        InvokeRepeating("CreateEnemy", 4, 5);

        //外墙
        for (int i = -11; i < 12; i++) {
            CreateItem(item[6], new Vector3(i, 9, 0), Quaternion.identity);
            CreateItem(item[6], new Vector3(i, -9, 0), Quaternion.identity);
        }
        for (int i = -8; i < 9; i++)
        {
            CreateItem(item[6], new Vector3(-11, i, 0), Quaternion.identity);
            CreateItem(item[6], new Vector3(11, i, 0), Quaternion.identity);
        }
        //地图
        for (int i = 0; i < 60; i++)
            CreateItem(item[1], CreateRandomPos(), Quaternion.identity);
            CreateItem(item[2], CreateRandomPos(), Quaternion.identity);
            CreateItem(item[4], CreateRandomPos(), Quaternion.identity);
CreateItem(item[5], CreateRandomPos(), Quaternion.identity);

}

6.其他

添加声音：Public AudioClip audio; AudioSource.PlayClipAtPoint(dieAudio, transform.position);
