c++ - 函数调用缺少参数列表错误

Question

我正在尝试转换 bullet四元数(btQuaternion)到 irrlicht四元数(irr::core::quaternion)用于游戏原型(prototype)制作。

        btQuaternion orientation= rigidBody->getOrientation();//now turn bullet quaternion -> irrlicht
        finalOrientation= core::quaternion(orientation.getX, orientation.getY, orientation.getZ, orientation.getW);

但是我遇到了一个我无法弄清楚的错误。

Error   1   error C3867: 'btQuadWord::getX': function call missing argument list; use '&btQuadWord::getX' to create a pointer to member c:\users\matia\documents\visual studio 2008\projects\bulletimplant\bulletimplant\bulletimplant.cpp  86
Error   2   error C3867: 'btQuadWord::getY': function call missing argument list; use '&btQuadWord::getY' to create a pointer to member c:\users\matia\documents\visual studio 2008\projects\bulletimplant\bulletimplant\bulletimplant.cpp  86
Error   3   error C3867: 'btQuadWord::getZ': function call missing argument list; use '&btQuadWord::getZ' to create a pointer to member c:\users\matia\documents\visual studio 2008\projects\bulletimplant\bulletimplant\bulletimplant.cpp  86
Error   4   error C3867: 'btQuaternion::getW': function call missing argument list; use '&btQuaternion::getW' to create a pointer to member c:\users\matia\documents\visual studio 2008\projects\bulletimplant\bulletimplant\bulletimplant.cpp  86

visual studio 提示函数调用缺少参数列表，但我找不到解决方案。请帮忙。谢谢

Answer 1

假设没有一个函数需要任何参数，我相信你需要:

finalOrientation= core::quaternion(orientation.getX(), orientation.getY(), orientation.getZ(), orientation.getW());

编译器报错，因为getX、getY、getZ和getW是函数，应该遵循函数调用时通过参数列表。
