敌方Boss移动AI

Question

我试图让敌方首领船出现在屏幕上并攻击我的船，有时也会躲避我的攻击。到目前为止，我已经让他攻击我的船，但他仍停留在屏幕边缘。

这是我的代码：

#pragma strict

// here are public variables for the enemy ship that can be accessed in the inspector
var health:int = 2;
var explosion:GameObject;
var expOrb:GameObject;
var enemyBullet:GameObject;
var expDrop:int = 3;
var hitSound:AudioClip;
var fireRate:float = 2.0;

//heres the private variable counter to keep track of time for fire rate.
private var counter:float = 0.0;

function Update () {
   //here we make counter count based on time for the fire rate
   counter += Time.deltaTime;

   //if the ship goes too far left, we destroy it.
   if(transform.position.x < -12){
      Destroy(gameObject);
   }

   //here we shoot 4 bullets if the counter counts higher than the fire rate.
   if(counter > fireRate){
      var custom1 = Instantiate(enemyBullet, transform.position - Vector3(0.5,0.1,0), Quaternion.Euler(-90,0,0));
      var custom2 = Instantiate(enemyBullet, transform.position - Vector3(0.5,0.1,0), Quaternion.Euler(-90,0,0));
      var custom3 = Instantiate(enemyBullet, transform.position- Vector3(0.5,0.1,0), Quaternion.Euler(-90,0,0));
      var custom4 = Instantiate(enemyBullet, transform.position- Vector3(0.5,0.1,0), Quaternion.Euler(-90,0,0));
      //to make the bullets spread, we add extra z velocity to each one to they all move on their own path.
      custom1.rigidbody.velocity.z = 3;
      custom2.rigidbody.velocity.z = 1;
      custom3.rigidbody.velocity.z = -1;
      custom4.rigidbody.velocity.z = -3;
      counter = 0.0;
   }

   //end of function update
}

//if a bullet hits the ship, the bullets sends us the hit message to trigger this function to bring down the ships health
function hit () {
   health -= 1;
   if(health != 0){
      if(audio.enabled == true){
         audio.PlayOneShot(hitSound);
      }
   }
   if(health <= 0){
      onDeath();
   }
}

//if health is 0, then this function is triggered to spawn some orbs, spawn the explosion animation object, and destroy itself
function onDeath () {
   Instantiate(expOrb,transform.position,Quaternion.Euler(-90,0,0));
   expDrop -= 1;
   if(expDrop <= 0){


       Instantiate(explosion,transform.position,Quaternion.Euler(-90,Random.Range(-180,180),0));
       Destroy(gameObject);
    }
    if(expDrop > 0){
       onDeath();
    }
 }

如何为其添加运动方面？

Answer 1

移动物体的方法有很多种，你可以尝试：

1. Transform.translate

   （http://docs.unity3d.com/ScriptReference/Transform.Translate.html）

2. 修改

   transform.position

   (http://answers.unity3d.com/questions/188998/transformposition.html)

3. 为其添加力量 (http://docs.unity3d.com/ScriptReference/Rigidbody.AddForce.html)

4. 还有许多我可能还不知道的其他方式。

对于此类游戏中的 Boss，您可能想要的移动要么是随机移动，要么是跟随玩家。两者都不难实现。

• 随机移动：只需做一个

  Random.Range(-1, 1) * bossSpeed *
  time.deltaTime

  并将其应用到老板的x位置。
• 跟随玩家：获取玩家的x位置，然后让boss调整到该位置。

那么如何让boss有时候躲避玩家的子弹呢？您可以通过在玩家的子弹前面添加一个对撞机来让 Boss 检测到玩家的子弹是否射来。如果玩家的子弹与之碰撞，则随机生成另一个数字（例如从 0 到 1）。之后，如果随机数为1，则只需将boss移开即可，而当随机数为0时，则不要移动boss。
