【Unity3D】游戏常用点整理-飞机射击类游戏_transform spawnpos

以下内容为泰课视频的学习笔记

1）飞机控制

在有限的范围内上下左右移动

public  class Boundary {
    public float xMin = -6.5f;
    public float xMax = 6.5f;
    public float zMin = -1.5f;
    public float zMax = 11.0f;
}

public Boundary boundary;

void FixedUpdate() {
        float h = Input.GetAxis("Horizontal");
        float v = Input.GetAxis("Vertical");
        Vector3 move = new Vector3(h, 0f, v);
 
        rigidbody.velocity = speed * move;
        rigidbody.position = new Vector3(
            Mathf.Clamp(rigidbody.position.x,boundary.xMin, boundary.xMax),
            0,
            Mathf.Clamp(rigidbody.position.z, boundary.zMin, boundary.zMax)
            );
    }

设定一个speed 

2）发射子弹

    public GameObject bolt;//子弹
    public Transform spawnpos;//  发射位置
 
    public float fireRate = 0.25f;//发射时间间隔
    private float nextFire;//下次发射时间
 
    public AudioClip fire;
 
    void Update() {
        if (Input.GetButton("Fire1")&&(Time.time>nextFire)) {
            nextFire = Time.time + fireRate;
            Instantiate(bolt, spawnpos.position, spawnpos.rotation);
            audio.PlayOneShot(fire);
        }
    }

加了生效,记得要添加一个空的Audio Source

3）生成敌人

public Vector3 spawnValues;

void Enemy() {
        GameObject o = enemy[Random.Range(0, enemy.Length)];
        Vector3 p = new Vector3(Random.Range(-spawnValues.x,spawnValues.x),spawnValues.y,spawnValues.z);
        Quaternion q = Quaternion.identity;
        Instantiate(o, p, q);
    }

enemy数组装不同的敌人

在spawnValues附近生成

4）敌人移动

public float speed = 10;
	void Start () {
        rigidbody.velocity = transform.forward * speed;
	}

5）几波敌人的进攻

    public int NumPerWave = 10;//一波敌人数量
    public float spawnWait = 1f;//敌人间隔出现时间
    public float startWait = 2f;//游戏开始等待时间
    public float waveWait = 4f;//每两波间隔出现时间
    void Start () {
        StartCoroutine(SpawnWaves());
	}
    IEnumerator SpawnWaves() {
        yield return new WaitForSeconds(startWait);
        while (true) {
            for (int i = 0; i < NumPerWave; i++) {
                Enemy();//生成敌人
                yield return new WaitForSeconds(spawnWait);
                    }
            yield return new WaitForSeconds(waveWait);
        }
        
    }

6）kill与反kill

public GameObject enemyExplosion;
public GameObject playerExplosion;
 
    void OnTriggerEnter(Collider other) {
        if (other.gameObject.tag == "player")
        {
            Instantiate(playerExplosion, this.transform.position, this.transform.rotation);
        }
        Destroy(other.gameObject);
        Destroy(this.gameObject);
        Instantiate(enemyExplosion, this.transform.position, this.transform.rotation);
    }

对象是敌人，遇到子弹bang，遇到玩家bang，分别播放动画

下面一些小东东

7）移动

 public float speed = 10;
	void Start () {
        rigidbody.velocity = transform.forward * speed;
	}

8）边界设置（出边界，就销毁）

添加一gameobject，collider设置成边界大小或稍大点。

public class DestroyByBoundary : MonoBehaviour {
 
    void OnTriggerExit(Collider other) {
        Destroy(other.gameObject);
    }
}

9）让敌人滚动起来

public class RandomRotater : MonoBehaviour {
    public float tumble = 5;
	void Start () {
        rigidbody.angularVelocity = Random.insideUnitSphere * tumble;
	}
}

10) bang 几秒后，自动销毁对象

public class DestroyByTime : MonoBehaviour {
    public float lifetime;
	void Start () {
        Destroy(this.gameObject, lifetime);
	}
}
