Unity 3d中是否可以检测碰撞发生了多少次?
例如,如果3次则杀死敌人。
或两次将寿命减少50%。
我想用void OnCollisionEnter
函数来做到这一点。
这是我的AI代码和我的玩家代码:
public Transform[] Targets;
private int DestPoint = 0;
private NavMeshAgent Agent;
public Transform Player;
public Rigidbody Bullet;
public Transform Instantiator;
public float BulletSpeed;
public float fireRate;
private float nextFire = 0F;
void Start()
{
Agent = GetComponent<NavMeshAgent> ();
Agent.autoBraking = false;
}
void Update()
{
if (Vector3.Distance(transform.position, Player.position) < 100)
{
transform.LookAt (Player);
if (Time.time > nextFire)
{
nextFire = Time.time + fireRate;
Agent.Stop ();
Shoot ();
}
}
else if (Vector3.Distance(transform.position, Player.position) > 100)
{
GotoNextPoint ();
}
}
void GotoNextPoint()
{
Agent.destination = Targets [DestPoint].position;
DestPoint = (DestPoint + 1) % Targets.Length;
}
void Shoot()
{
Rigidbody Clone = Instantiate (Bullet, Instantiator.position, Instantiator.rotation) as Rigidbody;
Clone.AddForce (Instantiator.forward * Time.deltaTime * BulletSpeed);
}
public float Speed;
public float RotationSpeed;
public Rigidbody Bullet;
public float BulletSpeed;
public Transform Instantiator;
public float fireRate;
private float nextFire = 0F;
void Update()
{
if (CrossPlatformInputManager.GetAxis("Vertical") > 0)
{
transform.Translate (Vector3.forward * Time.deltaTime * Speed);
}
if (CrossPlatformInputManager.GetAxis("Vertical") < 0)
{
transform.Translate (Vector3.back * Time.deltaTime * Speed);
}
if (CrossPlatformInputManager.GetAxis("Horizontal") > 0)
{
transform.Rotate (Vector3.up * Time.deltaTime * RotationSpeed);
}
if (CrossPlatformInputManager.GetAxis("Horizontal") < 0)
{
transform.Rotate (Vector3.down * Time.deltaTime * RotationSpeed);
}
if (CrossPlatformInputManager.GetButtonDown ("Shoot") && Time.time > nextFire)
{
nextFire = Time.time + fireRate;
Rigidbody Clone = Instantiate (Bullet, Instantiator.position, Instantiator.rotation);
Clone.AddForce (Instantiator.forward * Time.deltaTime * BulletSpeed);
}
}
最佳答案
OnCollisionEnter
函数没有为此内置的变量或函数。您必须为此创建一个变量,然后在每次冲突时增加该变量。没有其他方法可以做到这一点。
int collisonCounter = 0;
void OnCollisionEnter(Collision collision)
{
//Increment Collison
collisonCounter++;
if (collisonCounter == 2)
{
//reduce the life by 50 percent
}
if (collisonCounter == 3)
{
// kill the enemy
//Reset counter
collisonCounter = 0;
}
}
