Well im running debug mode, since release mode is totally screwed up somehow, it breaks once my gam runs, anyway before testing your example my game was running just fine, but now my debug\KoD.exe is gone

Read my post (second post) on how to fix it. http://forum.thegamecreators.com/?m=forum_view&t=154012&b=22

Maybe the running in release mode problem is caused by not initializing variables correctly.

ok i think everything works now.
except one thing
when i call CreateCreature function then DrawObjects main camera (me) go to <X,Z> <0,-130>
why's that?

and oh well, i didnt mention that when my CreateCreature function used to create and draw the object, i had the same problem. what the hell i mean it has nothing to do with camera position O_o

Quote: "when i call CreateCreature function then DrawObjects main camera (me) go to <X,Z> <0,-130>"

Whenever you create or load a new object, the camera is automatically repositioned to try to look at the new object. You can turn this behaviour off by dbAutoCamOff().

Also, if you have many objects to store in that vector (array, whatever), it would be a good idea to index the array directly with object ID. It is a bit more work to code correctly when objects are created/deleted, but it pays off in speed when you need to find the data block that belongs to an object ID.

In sprites, the black colour is transparent by default. Before putting it to the screen, try to apply this to the sprite:

+ Code Snippet

dbSetSprite(Sprite_ID, 1, 0);

From the documentation:
void dbSetSprite ( int iSprite, int iBackSave, int iTransparency )
If the transparency state is set to zero, the sprite will not treat black as a transparent color.

Your media needs to be in the right place relative to the "current directory". When you're in Visual Studion that happens to be the solution's folder. If your run the exe outside VS the current folder is the folder the exe is in. That's different folders for something compiled in debug mode vs. release mode.

Debug mode should be used strictly for development. When your program has all of the bugs out of it (debugged,) you compile in release mode in order to release it to others. Regardless of mode a .exe is generated but one is in the Debug folder and the other is in the Release folder. When you run either of these from a command prompt or from Windows Explorer the media needs to be relative to the folder that contains the .exe file you're running. When you're running it in either mode from VS the media files need to be relative to the folder where the solution resides.

So when you package the program up for release you need to make sure that the media files are where they belong since your users aren't going to be running from VS.... normally.

For fixing those release mode compile errors, try to select the menu Project / "Project" properties / Linker / Input. Make sure that "release" mode is selected in the drop-down menu of this options dialog box. In the line which says "ignore specific library", add the names of those libraries that the error messages are complaining about: MSVCRT.lib, libcmt.lib.

That's the only guess I have, this is a linker error and I don't know much either about configuring linking options for Visual Studio.

dbCheckDisplayMode() <-- this command works?

+ Code Snippet

if ( dbCheckDisplayMode (w, h, d) == 0)
		goto restart;

w,h and d are integers.

this compiles without errors, but when the program run and reach the if statement it gives me an error: Unhandled exception at 0x00c1b5eb in GDM.exe: 0xC0000005: Access violation reading location 0x00000594.

any ideas?

Just fishing here, but where is "restart" with respect to the "if" statement?

Have you tried setting a breakpoint at the "if" statement then stepping through the code to see what line it breaks on?

EDIT: OMG, A GOTO STATEMENT!!!!!!!

I don't think you can have a 12-bit color depth. Only 16 or 32.

that is not the reason, if so why this function exist? i think it should return 1 if the info is right and 0 if not, not cause an error if the mode doesnt exist

Put a breakpoint at the if statement and then check the values of w, h, and d before the function call. It wouldn't hurt to assign them initial values as part of the debuggin.

Ah I think I know why. In order for a DarkGDK function to work properly, I believe:

void DarkGDK()

Must be the entrance point for the program. (It has to be called by DarkGDK first)

dbExcuteFile doesn't depend on the support system that Dark GDK provides. It's probably just a shell for the Windows execute function. Otherwise, Dark GDK probably hasn't looked into the capability of the video until the DarkGDK() function has been called.

bah ill do it without a check then.

Is it possible to change the resolution while playing? well in some games i have played, there are options ingame for choosing the resolution, i wonder if that is possible using the DGDK.

Not quite sure what you're trying to do. Are these variables stored in a module you've linked in? If not, then don't use the extern specification.

Otherwise, you haven't really specified the problem you're having. Are you getting error messages when you compile?

typedef struct _creature
{
	int ID;
	char path[80];
	int health;
	struct
	{
		int X;
		int Y;
		int Z;
	} position;
	int ori;
	int scale;
	int loopit;
	bool killable;
	int speed;
	int hit_timer;
} creature;

vector<creature> creatV(0);

and now i want to declare this vector in the header file, here's my header atm:

+ Code Snippet

#pragma once

extern struct _creature creature;

extern vector<creature> creatV(0); // here is the problem

EDIT: im trying to use that vector from somewhere out of the cpp file, from anoth cpp file.

i have same problem with structures:
i have KoD.cpp and KoD.h, and Creatures.cpp and Creatures.h, in KoD.cpp i defined a structure:

+ Code Snippet

struct _player 
{
	int bullets;
	int maxbullets;
	int curhealth;
	int maxhealth;
	int Xloc;
	int Zloc;
} player;

and in the header :

+ Code Snippet

 extern struct _player player;

now i want to use it from creatures.cpp, i included KoD.h but it seems that the structure isnt deined:

Put the struct _player in a header file and put the assurances that it won't be redefined around it like so:

+ Code Snippet

#ifndef _PLAYER_H_
#define _PLAYER_H_
struct _player 
{
	int bullets;
	int maxbullets;
	int curhealth;
	int maxhealth;
	int Xloc;
	int Zloc;
} player;
#endif

Then include the header file in all of your .CPP files. Remove it from you .cpp file. This should assure that all modules know of the structure without giving a redefinition error.

that also works with vectors?
so i can make a header file like:

+ Code Snippet

#ifndef _CREATURE_H_ //this line
#define _CREATURE_H_ //this line

typedef struct _creature
{
	int ID;
	char path[80];
	int health;
	struct
	{
		int X;
		int Y;
		int Z;
	} position;
	int ori;
	int scale;
	int loopit;
	bool killable;
	int speed;
	int hit_timer;
} creature;

vector<creature> creatV(0);
#endif //this line

this header file's name must be _CREATURE_H.h?

and also..can you please explain what do these commands do (the ones with notes) and "#pragma once"? thanks alot, (i know my questions are endless

)

I'd be a bit concerned about including the declaration of the vector in the header. It would probably work but I can imagine some instances where it might not. <shrug>

#pragma once is supposed to replace all the #ifndef stuff I put in. I don't rely on it because I swear I tried to use it a few times and got some errors generated.

The text used in the #ifndef statement can be of your own choosing. I generally use the name of the header file in that sort of construction but often prepend my initials just to try to make sure it doesn't class with someone else's rendition.

Generally you put the structure and class declarations (types) into the header file, so that other modules which include that header can use them. The implementation part (the bodies of the functions and anything else other modules don't need to see) go into the cpp. The cpp should include its own header of course, and no need for extern.

Of course if you have a class or struct which is not to be used in more files than one, its code can go entirely into the cpp. Think of a header as the communication interface between different files.

It does not matter what the name of the header file is. It helps if it's similar to that string you define in the "ifndef" lines but not necessary. The main thing is that in the "include" instruction you use the header file name.

The "ifndef" is a conditional statement for the prepocessor which basically says: do not read these lines twice. The first time, since the flag is not defined yet, it is defined and everything else within the "if" lines is processed too. When these lines are read by the compiler more than once, the flag is already defined, so it won't read them again. This prevents double declaration errors.

The "pragma once" says exactly the same: read this header only once. So you use either the set of "ifndef" lines or just the "pragma once" in the beginning, they should be interchangeable.

P.S. Yes, you can declare a vector in the header file, but then the header must have #include <vector> in the beginning.

i have one more problem, there is an integer called iTime, it is my main integer for holding the time. i dont know where to define it, i have 2 cpp files and 2 header files, if i define it in the KoD.cpp and write "extern int iTime = 0" in KoD.h i get some linking errors, if i define it once in KoD.h i get 6 linking errors about structures, if i create a new header and define it there, i get the same set of linking errors, any ideas about where to define iTime? (it is used by both cpp files).

2 from the 2 structures 2 from the enums and 1 from the vector, any ideas about where to define them?

Quote: "} player;"

Quote: "_gamemodes eGameMode = eMainMenu;"

Quote: "_playerstate ePlayerState = eStop;"

You're declaring a variables in your header which you shouldn't do, the compiler needs to know where to store the variable and if you have it in a header and include it more than once from different source files you'll get that error. Instead, declare the variable in your cpp and declare an extern to it in your header if you need it to be visible to other files.

Also, "typedef struct _creature", this isn't C, you don't need to typedef all your structs/classes. Same goes for your earlier "extern struct _creature creature;".

So i should define the structure in the KoD header, then declare the varibale in the KoD.cpp, and in KoD.h i should use extern struct _creature creature; etc and then i can access creature variable from any other cpp file which is including KoD.h. i hope that was right

Almost. As I was implying, "extern struct _creature creature;", the struct part there should be removed. Other than this it should work fine provided you have header guards.
