我已经开始用 C++ 制作一个简单的游戏。

在这个阶段,我将所有字符和属性(图块)存储在一个文件中,然后将其加载到 CHAR_INFO。然后使用 WriteConsoleOutputA 我基本上可以绘制地图/世界。

这一切似乎都可以正常工作,并且没有显示问题。然而,当我开始移动我的角色时,他正在破坏瓷砖。有点难以解释,所以这里有一个小视频。http://www.youtube.com/watch?v=v5Be5qz30r8

如您所见,绿色瓷砖没有问题(前景和背景颜色相同)。但是当我靠近灰色瓷砖时,它并没有按预期工作。

main.cpp 片段...

int main()
{
    while (0 < 1)
    {

        if (GetAsyncKeyState(VK_UP) || GetAsyncKeyState(0x57))
            player.Move('u');
        if (GetAsyncKeyState(VK_DOWN) || GetAsyncKeyState(0x53))
            player.Move('d');
        if (GetAsyncKeyState(VK_LEFT) || GetAsyncKeyState(0x41))
            player.Move('l');
        if (GetAsyncKeyState(VK_RIGHT) || GetAsyncKeyState(0x44))
            player.Move('r');

        Sleep(100);
    }
}

字符类片段

void Character::Move(char d)
{
    COORD oldLoc = loc;
    char walkableTiles[12] = {
        4, 179, 191, 192, 193, 194, 195, 196, 197, 217, 218, 255
    };

    //set character
        switch (d) 
    {
        case 'u' :
            loc.Y--;
            break;
        case 'd':
            loc.Y++;
            break;
        case 'l':
            loc.X--;
            break;
        case 'r':
            loc.X++;
            break;
    }

    //setup the buffer and location of tiles
    CHAR_INFO newTile[1];
    COORD buffSize = {1,1};
    COORD buffPos = {0,0};
    SMALL_RECT newBuffArea = {loc.X, loc.Y, loc.X, loc.Y};
    SMALL_RECT oldBuffArea = {oldLoc.X, oldLoc.Y, oldLoc.X, oldLoc.Y};

    //store newTile info
    ReadConsoleOutputA(outHnd, newTile, buffSize, buffPos, &newBuffArea);
    //check if newTile is valid
    bool valid = 0; // assume not valid
    for (int i=0; i < sizeof(walkableTiles); i++)
    {
        if (newTile[0].Char.AsciiChar == walkableTiles[i])
            valid = 1;
    }

    if (!valid)
    {
        loc = oldLoc;
        return;
    }

    //restore oldTile information
    WriteConsoleOutputA(outHnd, oldTile, buffSize, buffPos, &oldBuffArea);

    //newTile becomes oldTile
    oldTile[0] = newTile[0];

    //get bg of newTile and set character/attributes
    int bg = (newTile[0].Attributes & Blue << BG ) | (newTile[0].Attributes & Red << BG) | (newTile[0].Attributes & Green << BG) | (newTile[0].Attributes & BACKGROUND_INTENSITY);
    newTile[0].Char.AsciiChar = 1;
    newTile[0].Attributes = White | bg;

    //place character on newTile
    WriteConsoleOutputA(outHnd, newTile, buffSize, buffPos, &newBuffArea);

为代码道歉,这是我的第一个游戏。
