linking source files

Hi guys!

I am writing a text adventure game, and it is all going really well at the moment.

I have written sevral source files for the game, and am using DevC++ in a project mode. when it comiples it, it says

COMPILE OK == LINK OK

this all sound possitive, but I am a bit weiry, that when I run the game, will it go the right file to read the code?

For exmaple, i have coded somthing like

(health<=0)


but will it go to the gameover file to read the code or just continue? I know all this sounds really silly as all I have to do is test it, but if I have probs, how can I fix them??

I'm not sure what to say accept no.. the game will start at int main(); whereever it is in your files. And you know .. it will do whatever you tell it to do in main.

COMPILE OK == LINK OK

This probably means that your files are compiled and linked, and therfore an exe file is created.

When you execute the program, computer doesn't any longer use (or even need) the source files you've written. It just executes the commands that are stored in the exe file (which has been created from your source files by the compiler).

Code:

 but will it go to the gameover file to read the code or just continue?

Well, if you've got something like:

gameover.cpp:

Code:

void GameOver()
{
//code...
}

main.cpp:

Code:

extern void GameOver();

int main()
{
//...
if(health<=0) GameOver();
//...
}

Surely, this is going to work. If you could post some code, it would be a lot easier to answer your question.

below is the main() function and basicly the main game it's self, this all compiles fine with on errors or link errors

Code:

#include <iostream>
#include <string>
#include <stdlib.h>
#include <cctype>  // files used
#include <windows.h>
#include <algorithm>
#include <conio.h>


using namespace std; // for cout and endl;

I've looked quickly through the code and I don't see anything wrong with it (at least at the first glance).

Though I haven't run it (working in linux only, and didn't want to install a windoze compiler... ). You should test it of course, and then see if you get any strange behavior.

Looks like a nice game... Keep up the good work

wow... thats what im trying to be able to do! but im kind of far from being able to (i think...) but it looks nice... im with mathfan... i dont want to install windows compiler to try and play it

It looks good. If it compiles fine and links fine then it will create a .exe which will run anything in int main():

Code:

int main(int argc, char *argv[])
{

SetConsoleTitle("W I Z A D O R A - BY PETER WATTS -"); // console Title
intro();
level1();
plea();
wizavillage();
signpost();
endingANDcredits();

if(health<=0) gameover();

return 0;
} // end main

Code:

will it go to the gameover file to read the code or just continue?

If you didnt include gameover(); in int main() then it wouldnt have read the code. But since you did, it will.

I think the only thing is somehow you need to make that line "if(health<=0) gameover();" an infinite loop so it will be called exactly when it happens (if you die early in the game) and not at the end of all those functions being finished. This.. I'm not sure how to do. Something to do with seperate windows (using win32 API) I think.. maybe.
