C ++ COORD错误(C++ COORD error)

C ++ COORD错误(C++ COORD error)

我正在尝试创建一个俄罗斯方块游戏，当我称之为：

void PrintChar(int x, int y, char ch, Colors color) { COORD c = { y,x }; FillConsoleOutputCharacterW(GameData::handle, ch, 1, c, NULL); FillConsoleOutputAttribute(GameData::handle, color, 1, c, NULL); }

出现此警告：

C4838 - 从'int'转换为'SHORT'需要缩小转换。

有人可以解释这里发生了什么，一个小例子将不胜感激。

I'm currently trying to create a Tetris game and when I call this:

void PrintChar(int x, int y, char ch, Colors color) { COORD c = { y,x }; FillConsoleOutputCharacterW(GameData::handle, ch, 1, c, NULL); FillConsoleOutputAttribute(GameData::handle, color, 1, c, NULL); }

this Warning comes up:

C4838 - conversion from 'int' to 'SHORT' requires a narrowing conversion.

Could someone please explain what is happening here and a small example would be greatly appreciated.

最满意答案

您应该使用显式类型转换

COORD c = { static_cast<short>(x), static_cast<short>(y) };

You should use explicit typecast

COORD c = { static_cast<short>(x), static_cast<short>(y) };
