loading levels data

[robertgarand]

Hi all,
I am looking for the "best" way to store and retrieve level data ( number of enemy, speed, terrain mesh name, etc)
I use a struct to load in game, but where should I put them without using a file, or if I must use file, can anyone direct me to a snippet.

Thanks,
Robert

Do you mean how can you do it without saving it to a file on your computer? Obviously you can't do it any other way (could use a database)... how would you imagine the data being 'saved' without it actually being written to disc? Once the game has been closed it would be lost if it were just kept in memory...

There's plenty of C/C++ tutorials on the net showing you how to read and write from files, google it!

Hi JP,
I have worked with file I/O, but now I want to save the data level in the source. I have made many tries with 2 dimensions array but none work correctly. An array of 10 x 5, that contains class object, int, vector,pointer,
I wan to initialize it in the code, so it s compile with code.

And I googledddd a lot

Thanks for the reply,
Robert

Okay, well JP just spelled it out for you. Everything piece of memory that your program is using is lost when it terminates. Now of course you could use SMC (Self-Modifying Code) if you were working on the assembly level. But even then, it is a bad practiced, and usually only used on low-end systems like the TI calculators, etc.

So bottom-line, use a file!

How unfortunate.

Super, go ahead and do so.

What you are asking is:

1) Fundamentally trivial. Storing data in the executable's memory just requires that you declare an array containing those data.

2) So application dependent that I can't possibly guess why your current implementation isn't doing what you expect it to do. I have no idea what the significance of a 10x5 array is to your app.

The only thing that I can suggest is that if you're really storing "pointers" in your data and expecting them to be valid, then you're going to be sorely disappointed.

It's REALLY starting to piss me off to read people saying "sorry, I'm X, this explains my bad English or what's not". Christian and I are both québecois too, do we have trouble writing or understanding English? No. Crap it, in Québec, it's the second language. In most countries, people learn up to 4 languages and keep practicing 3 throughout their lives. And if worst come to worst, it's not so hard to install a corrector plug-in for you favorite browser coupled with a dictionary. Just stop trying to justify your level in a language based on your nationality. Grrrrr.


Also, just try something like that:
savefile.txt : "Blahblahblah inc"
in your code : std::string savefile("Blahblahblah inc");

your loading function
load(std::string data)

or something similar. That way, it will make no difference whether it comes from a file or your code.

This is what I was after:

Code: Select all

typedef struct
	{irr::c8 *map;
	irr::c8 *texture_map;
	int max_shellc;
	int max_jetc;
	int max_tankc;
	irr::f32 shell_speedc;
	irr::f32 jet_speedc;
	irr::f32 tank_speedc;	
	irr::core::vector3df gravityc;
	}level;
level data_level[2] ={
{"scenes//sol_quad.ms3d", "textures//sol_quad.jpg", 5, 3, 0, 0.3f, 0.05f, 0.5f, 
irr::core::vector3df(0.0f,-0.003f,0.0f)},
{"scenes//sol_mars.ms3d", "textures//sol_mars.jpg", 5, 7, 0, 0.03f, 0.07f,0.5f,
irr::core::vector3df(0.0f,-0.002f,0.0f)}
};

It is much easier to modify when developping the game.
Thanks for the time you gave,
