Cached Compiling?

[Cerez]

I'm having a strange problem with compiling my custom OpenJK code: whatever changes I implement in the MP code don't show up in the final build. It feels like I have a build cache somewhere that needs cleaning. Either that, or I'm not doing something right with the OpenJK DLLs...

 

Any tips on how to start a clean build, or why my changes are not happening with my custom-built OpenJK MP binary?

 

I was thinking of running a "make clean". Could that help?

[Cerez]

I've found something that may be a clue:

 

The "gamename" when I load up OpenJK MP Solo mode is "basejka", not "OpenJK", and that exactly how it seems to be behaving. For some reason it's still running the base engine, and not my custom build of OpenJK. ... Why?

 

The OpenJK cgamex86.dll and uix86.dll are in GameData/base, along with jagamex86.dll and jampgamex86.dll. The OpenJK binaries are in GameData, along with rd-vanilla_x86.dll and rdsp-vanilla_x86.dll. Is this a setting (at compile-time) I'm not aware of? What gives??

[Cerez]

This thing's killing me! My Mac build does what it's supposed to, and my Windows build ignores my changes. WTH?! I really need help from an OpenJK expert. @@Xycaleth, @@eezstreet, @@ensiform, @@redsaurus, @@mrwonko, ..?

As always, if you don't want to run base you need to specify the fs_game on startup.

@@Cerez We've had some reports of usability issues recently where DLLs are saved in My Games/OpenJK/<mod folder>, and then these are loaded on subsequent runs instead of those found in the JKA GameData folder. So to answer your question: you might have old DLLs lying around in My Games/OpenJK/<mod folder> - make sure you delete them

 

We've come up with a fix for this problem and just need to code it up.

@@Xycaleth @@mrwonko Thanks guys. Finally managed to track it down, but this is really strange... Despite the fact that I have the OpenJK DLLs placed in my "GameData/base", the game is copying the basejka DLLs to "Documents/My Games/OpenJK/base" (even after a delete), and overriding what's in my "GameData/base" that way for some reason...

 

What I did to fix this was to manually replace these DLLs (in "Documents/My Games/OpenJK/base") with the OpenJK ones.

That's the usability issue that we're fixing

Oh good.

 

There is one drawback to my manual fix method: when I join a pure basejka server, the DLLs are reverted, and I have to copy and replace them all over again.

That's going to happen regardless.  It only uses pk3s from the server thus it pulls the DLLs from the base assets pk3.

No, I mean it literally copies the DLLs from the base assets into "Documents/My Games/OpenJK/base", replacing my OpenJK ones. After I join a pure basejka server, the whole thing reverts to the basejka game engine permanently. I need to do the manual replacement on the DLLs again.

 

Edit:

 

That gives me an idea: what if I revoked writing permissions for the game on these DLLs?

[ensiform]

That's still going to happen when you join a base pure server.  The same thing happened before, it was just all happening in GameData.

 

Are yours not in a PK3 at all?  It should go back to using yours if they are in a pk3 when not sv_pure 1 and on solo.

I'm not following... It was happening in GameData? What? The copying?

They're not, currently. If I were to put them in a PK3, would they still need to be in "GameData/base" for this to work? Or should I put the PK3 in "Documents/My Games/OpenJK/base"? This is so confusing...

Okay, now we're getting there! So jampgamex86.dll, cgamex86.dll and uix86.dll need to be packaged into a PK3 and placed in "Documents/My Games/OpenJK/base" for this to work! If you do the same for "GameData/base", the game craps on you and does what it feels like. Also, if you don't package the files into a PK3, the game craps on you and does what it feels like (when joining a pure server). So that leaves you with a lot of choice.

 

(Documentation, anyone?)

[ensiform]

jamp.exe copied base dlls to the (GameData/fs_game) folder too when joining a pure base server this has not changed only the location.

 

You can put your pk3 in gamedata and it will still copy to homepath just fine.  I don't see what is confusing.  PK3s are loaded from both locations, writes/copies of any kind only happen in My Games now is the main difference between jamp and OpenJK.

[Cerez]

Nope, that theory goes out the window... at least until the usability issue is fixed.

 

The reason it's confusing is because there are too many locations the game is placing stuff into, and it's not clear to the user what order the game is prioritising these locations in loading sequence, and what it's overwriting, and whatnot.

[mrwonko]

The game is only ever placing stuff into one location.

[ensiform]

PK3 in gamedata will still work just fine and place it where all things are written to as I said usability is irrelevant.

 

Priorities are the same as jamp, just the homepath was empty by default on windows.

[Cerez]

Sorry, I meant "for us to place into for the game"...

[Cerez]

It doesn't work. When the PK3 is placed in "GameData/base", the game doesn't copy it to "Documents/My Games/OpenJK/base", and the latter takes precedence in loading, where the game will copy the basejka DLLs and basically override your custom engine. So unless you place your PK3 in "Documents/My Games/OpenJK/base", currently your custom built engine will not work.

[ensiform]

What did you call the pk3? If its sorted alphabetically before assets3.pk3, of course the base one will get used first.

[Cerez]

I know that the game loads the assets alphabetically, but backwards. Whatever is after "assets" will get prioritised. I called it "openjk.pk3", the same as in the latest official releases of OpenJK.
