Okay, so, here I am. Improving my engine. Making things a bit more organized, etc.

Life is well, until I decide I want to make my game resources load through a resources.h/resources.cpp file.

I have resources.h that declares BITMAP* buffer; and prototypes load_resources() and unload_resources(). Then data is is placed into the bitmap, and prototypes are declared in my resources.cpp file.

First off, when I try to include resources.h in both my main.cpp file, and my resources.cpp file, I get a redefinition error of 'buffer'.


I have a feeling I'm going entirely the wrong way with this. Because if I wanted all the resource variables to be global I'd have to define them outside of a function. And at the moment, I'm calling my _resources() functions inside of main.
I can't just call functions outside of a function, so how should I do this? Classes?

I admit... I cheat.

For example, I would have a resources.h file, but it would simply define a list of methods that allow me to do what I need for the game.

Inside the resources.cpp file, I place all the variables that will be used globally.  I then alter/get those variables using the functions.

Yeah you probably should be using static variables in your class and then wherever you need it you can just use the class anywhere.  But where is the fun in that?  ::)

Yeah, I'd have a class to manage your resources. I have a GetImage(string) function that checks a map<string, Image> to see if it's in it - if it isn't, it loads it in and returns it, if it is, it just returns it.

Also, with the redefinition problem, I believe you want to google "include guards".

Hahah!  :D

Static variables+classes it is. After a bit of work, things are functioning properly.
Thanks.  :epileptic:

@Schtee
It's weird, my IDE(C::B) automatically places in include guards, but they don't ever seem to work. (ifndef, define, endif)

Hello everyone.

I'm back with more trouble~

In ship.cpp when I try to declare the following: sprite = *resources.gfx_player;
I get an error, which is error: 'resources' was not declared in this scope.

Even though I declared 'resources' in main.cpp as an instance of my resource manager class.(and not declared in the 'main' function)

How can I solve this?

Say no to Singleton.

If you want globals variables in this manner, you need to declare them as "extern" in the header, and put the actual variable in the cpp file, like so:

Header:

Seconded.  Singleton is widely considered to be an anti-pattern now.

I'm not using Singleton, actually.  8)

resources.h

Hmm, I could retrofit that for my resource_manager class. Thank you, I'll try it.

You're an anti-pattern.

I ended up having issues with my resource_manager class, and just using straight global variables.

Thank you Average Software.  :)
