最佳答案

您的示例太大而无法破译，但我会给您一些提示。

1) 总是初始化你的变量。

2) 在 al_init 运行之前不要加载资源。这意味着您在 al_init 之前拥有的所有对象将自动无法加载它们需要的任何资源。全局对象也是如此，因为它们是在 al_init 运行之前创建的。

3) 如果资源未加载，则可能适用以下情况之一:

A) 文件名不正确。

B) 当前工作目录错误

C) 不支持您尝试加载的资源格式。

您可以通过为您的资源尝试绝对路径来消除 3A。如果调用成功，您就知道问题出在 B)，因为程序在错误的目录中查找您的文件。如果您排除了 A 并通过为程序设置正确的工作目录修复了 B，并且加载函数返回 NULL，那么 C 很可能是答案。

如果 C) 是问题所在，那么有几个选项可以解决它。

1) 确保您正在使用的格式支持已内置到您正在使用的 allegro 版本中。

2) 向 allegro 提交补丁以支持不支持的格式。
