Acessing same class object throughout whole game.

I thought I got my income wars game set since I now understand pointers. But, apparently not.

I get this:
1>------ Build started: Project: Chili DirectX Framework, Configuration: Debug Win32 ------
1>Game.obj : error LNK2019: unresolved external symbol "public: void __thiscall turret::attack(int,int,int,int,int,int,class Marine *)" (?attack@turret@@QAEXHHHHHHPAVMarine@@@Z) referenced in function "private: void __thiscall Game::ComposeFrame(void)" (?ComposeFrame@Game@@AAEXXZ)
1>C:\Users\cameron\Desktop\Income wars7 - Copy (2) - Copy\Chili DirectX Framework V12.04.24 (SFX)\Debug\Chili DirectX Framework.exe : fatal error LNK1120: 1 unresolved externals
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
for calling:
tur.attack(50,50,50,100,5,5,&mar);



Again sorry for needing help. I found intermediate lesson 3 was very informational and helpful for understanding references and pointers it all just made sense after seeing that.

Needing help is something to be sorry for. In fact, asking for help takes courage and a bit of humility. So in the most genuine of cases, asking for help is an admirable thing.

Regards to your error, I don't see how it relates to pointers. It looks like a class related issue. Something to do with public/private maybe?

I don't know how classes work in c++ yet, so I'll just stop at that for now. Hope that helps.

You would have to upload the project

[cameron]

lol I was about to do that I cleaned it and everything but never clicked the add file button lol here you go.

[cameron]

Does this have anything to do with class objects?

[LuX]

Kinda... Take another look at enemybase.cpp "attack" function.

[cameron]

I think it has something to do with that Marine* marin paramiter, not sure though.

[LuX]

Nah it's just a silly mistake you made. Pay closer attention to the first line.

[cameron]

Oh I forgot the scope lol.

[cameron]

Although I am passing the wrong instance of marine to the attack function.Ill have to fix that.
