我正在开发一款游戏，玩家必须通过登陆胸部来收集硬币。然而，如果他们三次落在同一个箱子上，它将删除那里的胸部，并在其位置插入一个强盗 - 这将把他们的硬币重置为零（这部分不包括在运行时提供的代码中）正确地）。

我知道你可以使用canvas.delete(item_id)来删除一个对象，因为它已被定义但我的问题是因为我用字典创建了我的对象，所以它们没有我可以使用的具体名称而且我我想知道如何根据画布的坐标而不是它的名称从画布中删除一个对象。
另外，作为附注，由于我使用的是图像，根据我找到的答案，格式必须是GIF，但我可以使用PNG格式，它仍然可以正常工作，但当我尝试我的在不同的设备上游戏，我得到了预期的错误。有这个原因吗？
答案 0 :(得分：0)
在 furas 的帮助下，我找到了一个解决方案：
由于每个胸部都有自己独特的行和列，您可以使用其行和列来引用单个胸部，这意味着我们必须找出该行和列的内容。
由于x1 = col * CELL_WIDTH + 24和y1 = row * CELL_HEIGHT - 26其中x1是x坐标而y1是y坐标，因此行和列的等式必须为(x1 - 24) / CELL_WIDTH = col和(y1 + 26) / CELL_HEIGHT = row。
然后，您可以使用arrow_coords[0]和arrow_coords[1]替换x和y坐标。要从chest_dict获取特定的行和列，然后将其四舍五入到最接近的整数，它将从画布中删除该特定的胸部：
game_grid.delete(chest_dict[int(round(int(arrow_coords[0]-24)/50, 0)),
int(round(int(arrow_coords[1]+26)/50, 0))])
