我遇到了错误。
“矢量下标超出范围，第932行。”
我有两种敌人类型，一组小行星，然后是一个单独的敌人。它们完全相同，只是小行星的数量是多个，而博格就是它自己的。我已经将错误跟踪到Borg的更新方法，这与Asteroids方法完全相同，并为Borg更改了一些名称。我已经尝试将“for”改为“if”，我试图将矢量数组更改为D3DXVECTOR3。我认为这是一个数组错误，但我的编程知识有限。以下是更新方法：

感谢您的帮助，如果我错过了什么，请抱歉。
答案 0 :(得分：1)
很难说所提供的信息，但是 你的问题可能就在这里：
在BorgGameState.h中更新（）
borg = *it;
if (m_vBorgRotation[i]->y <= 0)
m_vBorgRotation[i]->x -= m_vBorgRotation[i]->y;
else
m_vBorgRotation[i]->x += m_vBorgRotation[i]->y;
borg->SetRotationMatrix(m_vBorgRotation[i]->x);
i++;
if (i >= MaximumNumberOfAsteroids) // <--- should this be MaximumNumberOfBorg instead?
i = 0;
如果m_vBorgRotation的元素少于MaximumNumberOfAsteroids，则会出现这样的错误。
