Question

我在使用在线发现的教程中的一段代码时遇到了问题。我不断通过行public static Vector2获得解析器错误。

以下是代码。我找不到它的任何问题，并且会喜欢为什么这个错误不断出现的建议。谢谢！

using UnityEngine;
using System.Collections;

public class Grid : MonoBehaviour {
    // The Grid itself
    public static int w = 10;
    public static int h = 20;
    public static Transform[,] grid = new Transform[w, h];
}
public static Vector2 roundVec2(Vector2 v) {
    return new Vector2(Mathf.Round(v.x),
                       Mathf.Round(v.y));
}
public static void deleteRow(int y) {
    for (int x = 0; x < w; ++x) {
        Destroy(grid[x, y].gameObject);
        grid[x, y] = null;
    }
}
public static void decreaseRow(int y) {
    for (int x = 0; x < w; ++x) {
        if (grid[x, y] != null) {
            // Move one towards bottom
            grid[x, y-1] = grid[x, y];
            grid[x, y] = null;

            // Update Block position
            grid[x, y-1].position += new Vector3(0, -1, 0);
        }
    }
}
public static void decreaseRow(int y) {
    for (int x = 0; x < w; ++x) {
        if (grid[x, y] != null) {
            // Move one towards bottom
            grid[x, y-1] = grid[x, y];
            grid[x, y] = null;

            // Update Block position
            grid[x, y-1].position += new Vector3(0, -1, 0);
        }
    }
}
public static void decreaseRow(int y) {
    for (int x = 0; x < w; ++x) {
        if (grid[x, y] != null) {
            // Move one towards bottom
            grid[x, y-1] = grid[x, y];
            grid[x, y] = null;

            // Update Block position
            grid[x, y-1].position += new Vector3(0, -1, 0);
        }
    }
}
public static bool isRowFull(int y) {
    for (int x = 0; x < w; ++x)
        if (grid[x, y] == null)
            return false;
    return true;
}
public static void deleteFullRows() {
    for (int y = 0; y < h; ++y) {
        if (isRowFull(y)) {
            deleteRow(y);
            decreaseRowsAbove(y+1);
            --y;
        }
    }
}

错误讯息：

分析器错误：意外的符号'Vector2'，预期'class'，'delegate'，'enum'，'interface'，partial'或'struct'

Answer 1

看起来你要在线后关闭课程：

public static Transform[,] grid = new Transform[w, h];
}

将大括号移动到文件的末尾。

此外，为什么所有内容都被定义为static？ MonoBehavior旨在成为附加到游戏对象的实例对象。

试试这个：你要提前关闭课程

public static bool isRowFull(int y) {
    for (int x = 0; x < w; ++x)
        if (grid[x, y] == null)
            return false;
    return true;
}

在for循环中缺少括号。
