Unity:第5行错误CS1041:预期标识符:'public'是关键字？

Question

我一直关注Unity3D 程序洞穴生成,但我在MapGeneration.cs中很早就发现了一个错误.Unity说第1行第1行有一个错误:标识符预期:'public'是一个关键字.我看不出我的代码和教程代码有什么不同.这是教程视频的链接:[ \ Tutorial video 1],这是我的代码:

using UnityEngine;
using System.Collections;
using System

public class MapGeneration : MonoBehaviour {

    public int width;
    public int height;

    public string seed;
    public bool useRandomSeed;

    [Range(0,100)]
    public int randomFillPercent;

    int[,] map;

    void Start() {
        GenerateMap();
    }

    void GenerateMap() {
        map = new int[width,height];
    }

    void RandomFillMap() {
        if (useRandomSeed) {
            seed = Time.time.ToString();
        }

        System.Random psuedoRandom = new System.Random(seed.GetHashCode());

        for (int x = 0; x < width; x++) {
            for (int y = 0; y < height; y ++) {
                map[x,y] = (psuedoRandom.Next(0,100) < randomFillPercent)? 1: 0;
            }
        }
    }

    void OnDrawGizmos() {
        if (map != null) {
            for (int x = 0; x < width; x++) {
                for (int y = 0; y < height; y ++) {
                    Gizmos.color = (map[x,y] == 1)? Color.black: Color.white;
                    Vector3 position = new Vector3(-width/2 + x + .5f,0,-height/2 + y + .5f);
                    Gizmos.DrawCube(position,Vector3.one);
                }
            }
        }
    }
}

该错误在第一行公开.

你没有;后using System(也许,也是一个不完整的导入).
