Destroying Enemies
摧毁敌人
While the enemies can be shot by bullets and their health goes down, enemies should be destroyed when their health reaches zero.
敌人可以被子弹击中，身体降下来，当他们的健康达到零的时候，敌人就应该被消灭。
To do this, we will need to adjust the Health script to take into account the difference between players and enemies.
为了做到这一点，我们需要调整健康脚本，以考虑玩家和敌人之间的区别。
The easiest way to do this is with a check box for Destroy On Death.
最简单的方法是用一个复选框来销毁死亡。
Open the Health script for editing.
打开用于编辑的健康脚本。
Add a public field for the Destroy On Death check.
在死亡支票上添加一个公共字段。
public bool destroyOnDeath;
In TakeDamage, check Destroy On Death when Current Health reaches 0 before respawning.
if (destroyOnDeath)
{
Destroy(gameObject);
}
else
{
// existing Respawn code
}
The final Health Script should look like this:
Health
C#
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Networking;
using System.Collections;
public class Health : NetworkBehaviour {
public const int maxHealth = 100;
public bool destroyOnDeath;
[SyncVar(hook = "OnChangeHealth")]
public int currentHealth = maxHealth;
public RectTransform healthBar;
public void TakeDamage(int amount)
{
if (!isServer)
return;
currentHealth -= amount;
if (currentHealth <= 0)
{
if (destroyOnDeath)
{
Destroy(gameObject);
}
else
{
currentHealth = maxHealth;
// called on the Server, will be invoked on the Clients
RpcRespawn();
}
}
}
void OnChangeHealth (int currentHealth)
{
healthBar.sizeDelta = new Vector2(currentHealth, healthBar.sizeDelta.y);
}
[ClientRpc]
void RpcRespawn()
{ if (isLocalPlayer)
{
// Set the player’s position to origin
transform.position = Vector3.zero;
}
}
}
Save the script.
保存脚本。

Shooting the enemies will cause them to lose health and when their health reaches zero, the enemies will be destroyed.

The players, however, should retain the existing behaviour where they are moved back to the origin point when they “killed”, with their health restored to maximum.
然而，玩家应该保留现有的行为，当他们被“杀死”的时候回到原点，他们的健康恢复到最大。
