File Save

[Kanadaj]

Hey there guys!

I've seen some maps out there that could save the files in not codes but with creating local files and loading them... Can anyone tell me how Warcraft 3 can do that? Do I need JNGP? I guess so, but then what are the syntaxes for doing it?

It's possible to save files if the map is single player. For multiplayer, You should use a save/load system.

If you have seen a map that does that feature you said I want to see it ASAP.

I know about that, but I've seen a multiplayer map as well (cant remember what it was, but it was on THW). Still looking for it so I can show you

To save a file locally is:

call PreloadGenStart( )
call PreloadGenClear( )
call Preload( "\" )
call SetPlayerName( Player( 15 ) , \"" + YOURVALUECONVERTEDTOSTRING + "\" ) //")
call PreloadGenEnd( "Somedir\\Somefilename.Someextension" )

To load that value: call Preloader( "Somedir\\Somefilename.Someextension" ). Now you have it as the Player( 15 )'s name and you can get it with GetPlayerName( Player( 15 ) ). You can save integers with SetPlayerTechMaxAllowed but I don't rely on that method.

This is far not hard as the things come then: You have to make a full file structure for more character support and because warcraft only has 16 players so that is the max amount of string that can be saved into a single file. Or you have to make big strings like a common save system. So make some encryption and other things here. Also you have to synchronize the values you load cause other players likely won't have the files. Thats the harder thing. So good luck with it.

You could do that with triggers. But it will bug for sure.

woah thanks a lot geries
I've found the map which already utilizes this system: Shadows of Everwood ORPG

Also, is this JASS or vJASS?

EDIT: Shinji, you posted before I finished this post I've never met a trigger for saving anything locally for multiplayer games...

Not for sure. It depends on the way you sync and how you save files.

@kanadaj this is just a few line of jass, but the system you make can be anything.

Sometimes it can cause a data bug and more.

But I always have to use a player name to extract the content, or not?

Yes, you have to.

@shinji why would it do?

 

[shinji]

Yes, you have to.

@shinji why would it do?

I remember someone telling me that it bugs.

Nestharus' save system has this functionality too, if you need a full save lod system

There's a lot of way I believe to extract, but I believe using player name is the best way for this...

Btw, here's a list of released games that uses it, that I know of: TKoK, Guild of Hippos, Gaias
