C++/DX11從.H到的.cpp移動導致錯誤

我工作的一些directX，從教程代碼開始，也陸續將其轉化爲自己的階級制度和cpp文件等C++/DX11從.H到的.cpp移動導致錯誤

一切都已經直到現在一切順利，但我剛開始修改「Camera.h」和「Camera.cpp」。我有類函數在頭文件中，當我將它放在它的類文件中時，會出現一個錯誤。我有頭阻塞等，但我不能看到缺陷。

camera.h編輯

#ifndef CAMERA_H_ 
#define CAMERA_H_ 
#include "Player.h" 
#include "RandomVariables.h" 


class Camera { 
    public: 
     void UpdateCamera(); 
     float camPitch; 
     float camYaw; 
     float Zoom_Amount; //zoom amount from Model_1.Player 
     float charCamDist; //distance from Model_1.Player 

     XMVECTOR camPosition; 
     XMVECTOR camTarget; 
     XMVECTOR camUp; 
     XMVECTOR camRight; 
     XMVECTOR camForward; 

     XMMATRIX camRotationMatrix; 
     XMMATRIX Rotationx; 
     XMMATRIX Rotationy; 
     XMMATRIX Rotationz; 
     XMMATRIX camView; 
     XMMATRIX camProjection; 
}; 

Camera MainCamera; 

#endif

camera.h之前，我刪除無效照相機：UpdateCamera（），並把它放在攝像頭。 CPP和它出現未定義的錯誤等等，如果無效Camera :: UpdateCamera（）在頭文件中，所以我感到困惑：S

Camera.cpp移動updatecamera

    MainCamera.camTarget = XMVectorSetX(MainCamera.camTarget, XMVectorGetX(MainCamera.camTarget) -MainCamera.Zoom_Amount); 


    MainCamera.camRotationMatrix = XMMatrixRotationRollPitchYaw(-MainCamera.camPitch, MainCamera.camYaw, 0); 
    MainCamera.camPosition = XMVector3TransformNormal(DefaultForward, MainCamera.camRotationMatrix); 
    MainCamera.camPosition = XMVector3Normalize(MainCamera.camPosition); 

    MainCamera.camPosition = (MainCamera.camPosition * MainCamera.charCamDist) + MainCamera.camTarget; 

    MainCamera.camForward = XMVector3Normalize(MainCamera.camTarget - MainCamera.camPosition); // Get forward vector based on target 
    MainCamera.camForward = XMVectorSetY(MainCamera.camForward, 0.0f); // set forwards y component to 0 so it lays only on 
    // the xz plane 
    MainCamera.camForward = XMVector3Normalize(MainCamera.camForward); 
    MainCamera.camRight = XMVectorSet(-XMVectorGetZ(MainCamera.camForward), 0.0f, XMVectorGetX(MainCamera.camForward), 0.0f); 

    MainCamera.camUp =XMVector3Normalize(XMVector3Cross(XMVector3Normalize(MainCamera.camPosition - MainCamera.camTarget), MainCamera.camRight));

'攝像頭MainCamera;'把它放在標題中會讓你容易受到「多重定義」鏈接錯誤的影響。如果在多個源文件中包含'camera.h'，則會聲明多個MainCamera，這會導致這樣的錯誤。事實上，即使你解決了編譯問題，這就是*將會發生的事情。 – PaulMcKenzie 2015-03-31 15:26:11

鑑於它有#ifndef它不應該能夠重新定義MainCamera？它包含在多個文件中，然後移動cameraupdate功能 – Invictus 2015-03-31 15:32:22

不會。這不會發生。你有2個獨立的模塊，RandomVariables.cpp和Camera.cpp。他們將分開編譯，不是？所以當鏈接器現在看到'MainCamera'變量出現在RandomVariables和Camera對象代碼中時，鏈接器將發出錯誤。要麼停止使用全局變量，要麼學習如何在多模塊程序中使用它們。 http://stackoverflow.com/questions/9702053/how-to-declare-a-global-variable-in-c – PaulMcKenzie 2015-03-31 15:35:52

使用externs只是聲明相對cpp文件中的類對象解決了問題。
