I am using VC++. and am making an arkanoid game. i am setting up classes for my paddle, ball etc. i am having problems accessing the varible that i have put in the class. i am getting an unresolved external symbol. i only what to access the varibles in the fuctions in the class. my header file looks like this #ifndef paddleh_h #include <windows.h> // Header File For Windows #include <stdio.h> // Header File For #include <gl\gl.h> // Header File For The #include <gl\glu.h> // Header File For The #include <gl\glaux.h> // Header File For The Glaux #include <math.h> class Paddle { private: private float paddle_xpos; // Position components public: Paddle(); ~Paddle(); //Protypes static void UpdatePaddlePosition(float); static float GetPaddlePosition(void); static void DrawPaddle(float); static float LimitPaddleMovement(float); static void ResetPaddle(void); static void SpeedUpPaddle(void); static void SlowDownPaddle(void); }; #endif my .ccp file looks like this.. #include "paddleh.h" float Paddle::LimitPaddleMovement(float xpos) { if (xpos/*+BatWidth*/>=7.7) { xpos=7.7/*-BatWidth*/; } if (xpos/*-BatWidth*/<=-9.7) { xpos=/*BatWidth-*/-9.7; } return(xpos); } void Paddle::DrawPaddle(float xpos) { glBegin(GL_QUADS); glTexCoord2f(0.0f, 1.0f); glVertex3f(2.0f + xpos , 0.0f, 0.0f);//bottom right glTexCoord2f(1.0f, 1.0f); glVertex3f(-0.0f + xpos , 0.0f, 0.0f);//bottom left glTexCoord2f(1.0f, 0.0f); glVertex3f(-0.0f + xpos , -0.5f, 0.0f);//top left glTexCoord2f(0.0f, 0.0f); glVertex3f(2.0f + xpos , -0.5f, 0.0f);//top right glEnd(); // Done Drawing The Quad return; } void Paddle::UpdatePaddlePosition(float xpos) { if (xpos<0) Paddle:addle_xpos += xpos; else Paddle:addle_xpos -= xpos; return; } float Paddle::GetPaddlePosition(void) { return(Paddle:addle_xpos); //return(2); } any help would be greatful.
