即使没有错误，我的 Sprites 也没有绘制？

Question

这是我的 code.I 只是不知道为什么我的精灵不绘制。我在二维精灵数组的嵌套 for 循环中使用了 window.draw() 函数，但它没有绘制 it.Just 看看我的名为 Board 的二维精灵数组的嵌套循环。帮助将不胜感激。

Answer 1

您必须在事件循环之外绘制您的板。现在，您的看板只显示一次（当您单击鼠标左键时）。你应该在 'window.clear();':

之后写类似的东西

for (i = 0; i < 8; i++) 
   for (j = 0; j < 8; j++) 
      window.draw(Board[i][j]);

此外，您必须仅在游戏循环结束时使用 'window.display();' 一次。如果你想只要按下鼠标左键就可以绘制棋盘，你可以使用：

if(sf::Mouse::isButtonPressed(sf::Mouse::Left))
{
}

即使没有错误，我的 Sprites 也没有绘制？

My Sprites are not drawing even though there is no error?
