Unresolved externals caused by unused variables?

[nanoxax]

I have this chunck of code:

Code: Select all

   virtual void CalcView( Vector &eyeOrigin, QAngle &eyeAngles, float &zNear, float &zFar, float &fov );


In c_BaseCombatCharacter.h

I have it referenced where it is supposed to be and I have everything mapped out no errors prior to linkage or anything.

And then it says this:

Code: Select all

This leads me to believe that all these errors, are caused by the variable that I defined not being in use for these codes.

How do I make the defined variable only work with C_BasePlayer.cpp and not have to be referenced in any other code. But if this isn't the problem and there is a different solution to it please enlighten me.

I'm using this tutorial:

And I'm attempting to implement it into my singleplayer mod, if that helps any.

Code: Select all

error LNK2001: unresolved external symbol "public: virtual void __thiscall C_BaseCombatCharacter::CalcView(class Vector &,class QAngle &,float &,float &,float &)" (?CalcView@C_BaseCombatCharacter@@UAEXAAVVector@@AAVQAngle@@AAM22@Z)


Means you declared this function but didnt define it (=wrote the contents of the function).

What variable are you talking about?

[nanoxax]

Sorry for my vocabulary, when I say variable I mean function, specifically this function:

Code: Select all

   virtual void CalcView( Vector &eyeOrigin, QAngle &eyeAngles, float &zNear, float &zFar, float &fov );

I don't want to define it in every file that the error comes up in, I've already defined it in the file that needs it. How do I make it so that the other files that come up with problems shut the hell up when they ask for the function that they don't need. That is what I need to know.

the errors say you havent defined the function at all, you just declared it. So just define it and you should be al right.
