我是游戏编程和C#的新手,但是我有一些JavaScript和PHP的编程经验。
好的,我们开始吧,我有一个C#脚本,我想将其用于生成怪物。我已经在YouTube上关注汤姆·亚当森(Tom Adamson),直到他开始生成此处显示的随机值为止:UNITY3D C# with Tom Adamson
这是我的脚本:
using UnityEngine;
using System.Collections;
public class myMonster : MonoBehaviour {
public class aMonster {
//The properties
public int id;
public int age;
public string name;
public string race;
public int health;
//A method
public void monsterData() {
print("ID: " + id);
print("Race: " + race);
print("Name: " + name);
print("Age: " + age);
print("Health: " + health);
}
} // End of class definition
//-----------------------------------------------------------------------------------------
void Start () {
aMonster[] bigMonster = new aMonster[51];
for (int i = 1; i <= 50;) {
bigMonster[i] = new aMonster();
bigMonster[i].id = i;
bigMonster[i].name = "Gorky";
bigMonster[i].race = "Orc";
bigMonster[i].age = 320;
bigMonster[i].health = 200;
i++;
bigMonster[i] = new aMonster();
bigMonster[i].id = i;
bigMonster[i].name = "Runathu";
bigMonster[i].race = "Shaman";
bigMonster[i].age = 670;
bigMonster[i].health = 100;
i++;
}
for (int i = 1; i <= 2; i++) {
bigMonster[i].monsterData();
}
}
}
当我只有2个怪物时,此方法工作正常,但是当我尝试添加第三个怪物时,出现此错误:
IndexOutOfRangeException:数组索引超出范围。
(包装器stelemref)对象:stelemref(对象,intptr,对象)
myMonster.Start()(位于Assets / myMonster.cs:50)
我添加了第三个怪物,如下所示:
bigMonster[i] = new aMonster();
bigMonster[i].id = i;
bigMonster[i].name = "Gorky";
bigMonster[i].race = "Orc";
bigMonster[i].age = 320;
bigMonster[i].health = 200;
i++;
bigMonster[i] = new aMonster();
bigMonster[i].id = i;
bigMonster[i].name = "Runathu";
bigMonster[i].race = "Shaman";
bigMonster[i].age = 670;
bigMonster[i].health = 100;
i++;
bigMonster[i] = new aMonster();
bigMonster[i].id = i;
bigMonster[i].name = "Tiny";
bigMonster[i].race = "Spider";
bigMonster[i].age = 90;
bigMonster[i].health = 45;
i++;
谁能告诉我我在做什么错?我猜我是这样做的错误方法,因为第三个怪物引起了错误。
任何帮助深表感谢。
最佳答案
aMonster[] bigMonster = new aMonster[51];
表示您有51个怪兽(最大指数= 50),但您要在一次for循环中将i递增两次,最后一次迭代时i = 50,因此您尝试达到
aMonster[51]
固定:
从i = 0开始循环,在i = 49结束,c#中的索引从0开始而不是1
我也建议您将代码转换为:
for (int i = 0; i < 50; i+=2)
{
bigMonster[i] = new aMonster();
bigMonster[i].id = i;
bigMonster[i].name = "Gorky";
bigMonster[i].race = "Orc";
bigMonster[i].age = 320;
bigMonster[i].health = 200;
bigMonster[i+1] = new aMonster();
bigMonster[i+1].id = i;
bigMonster[i+1].name = "Runathu";
bigMonster[i+1].race = "Shaman";
bigMonster[i+1].age = 670;
bigMonster[i+1].health = 100;
}
for循环的增量应该在for循环的定义中完成,它看起来更干净。
编辑:
最优雅,最安全的解决方案,请使用
List<aMonster>()
var bigMonster = new List<aMonster>();
var id = 0;
for(int i=0; i<30; i++)
{
bigMonster.Add(new aMonster { id=id++,name="Gorky",race="Orc",age=320,health=200 });
bigMonster.Add(new aMonster { id=id++,name="Runathu",race="Shaman",age=320,health=200 });
//and so on
}
它会创建30种各种怪物,当然,您可以通过modyfing for loop更改此数字
