34.28 [Abandoned] [Java] ModelLoader 1.16_02

Jab · June 5, 2015

The ModelLoader is currently Unavailable for download. There is instead an open letter here:

https://dl.dropboxusercontent.com/u/31589881/PZ/ModelLoader/ModelLoader.html

Purpose:

The purpose of this mod is to expose and modify the model loading portion of the game in order to support customized models and their functions to be properly imported into the game.

Instructions:

Spoiler

- Simply copy the 'zombie' (and 'media' folder for v1.14+) in the main Project Zomboid install folder ("Steam/SteamApps/common/ProjectZomboid/"). Make sure to make a backup of the zombie folder, for in case you want to remove this mod. You can always verify your files using Steam.

	Equippable = (TRUE / FALSE)		

	-- This is the designated spot the game will say your item is being equipped to.

	-- You simply use the same location name you put here.

	-- The name of your model goes here.

Best of luck to you! I tried to do this exact thing, but I ran into issues with incomplete decompilation, and no bytecode editors having support for using classes as constants which Kahlua requires.

Jab · June 6, 2015

Updated the OP / First post.

So I have managed to modify the Lua portion of the code successfully, and also the model managing portions. So I've definitely made progress.

Think it would be possible to override the character rendering to look for models instead of sprites? That'd really be all that's needed to allow for clothing additions.

Not the backpacks and headgear everyone wants, though.

In this situation, I'd say the best route to take as far as the sprite stuff goes is to find a way to make our own sprites. Maybe this can be achieved using my soon-to-be-made model viewer. iirc, lemmy and binky made renders of things as sprite sheets, albiet a bit complicated as for each change to a character required a whole set of sprites for each difference and cosmetic component. This may be the exact reason why a move like model loading support has not been made yet. I believe the modding community can find a way around this issue. Maybe.

With the sheer magnitude of sprites its no doubt they're renders (otherwise whoever drew them is clinically insane). The problem with character sprites is that they're sheets of DDS files rather than PNG like everything else, which while they can be unpacked, no one has yet (I don't think) come up with a way of repackaging them in any usable way.

Maybe once animations are moddable, hopefully.

Jab · June 7, 2015

Initial version released with an example. I'll go ahead and test this for the current IWBUMS.

Break-Off · June 7, 2015

This is awesome! Can't wait to see this implemented and used by modders. Props to you, Jab! (tophat)

ORMtnMan · June 7, 2015

Hey, so I am super excited about this but I get a crash error when I load up with this

NoClassFoundDefError:zombie/iso/areas/safehouse

The last line below that mentions your lua exposer and Java 800.

Am I doing something wrong here?

I tested this on a fresh install of 32.5.

Are you sure you are modding 32.4 or 32.5?

Build 31 does not have this class.

That would be it, I am not on the IWBUMS. So, that's a requirement then?

Edit: Confirmed the upgrade to IWBUMS cleared it up. Guess my mod will require build 32 now... totally worth it though

ORMtnMan · June 19, 2015

Jab!

Please update for the 32.7! It just updated and killed my mod via the ModelLoader...

Will get it later today.

Wilson · June 19, 2015

I took our dedicated server offline until this is updated so ORGM is working again. Looking forward to an update soon! Cheers!

EDIT: Well, it appears the guns still work, they're just invisible so I've put the server back online. Hopefully ModelLoader gets updated soon.

Reblar · June 19, 2015

Does this have to be updated every single time there's a IWBUMS patch then?

ORMtnMan · June 19, 2015

Probably anytime they change the LUAmanager class

Such is the terror of modding a game still in Alpha/Beta

Jab · June 20, 2015

Updated.

Also, feel free to distro this mod if you need to.

Wilson · June 20, 2015

Thanks for the speedy update, Jab. ORGM is looking good once again!

lorneagle · June 21, 2015

Hey Jab,

I switched ZomboidXBow to your your modloader and it's now beautifully compatible with ORMtnMan's Real guns. Awesome work!! Everyone with custom models in their mod should use this.

LuaManager did have an update. Will push an update sometime within the next day.

JaRu · June 25, 2015

Hey there,

I´m using latest version of PZ (32.9) and your 1.01 version together with ORGM (1.235).

My problem is, as soon as my girlfriend wants to join a game in splitscreen mode she can´t use the Gamepad anymore.

It reacts, allows her to select her char and join the game, but the buttons on the pad stopp working. Only thing possible is using left stick to run arround and the button to add a new player (even after she is in the game and controls her char, she can select "add a new player")

When I copy over my backup of the "zombie" folder your plugin replaces or adds stuff to, it works all fine again... exept no guns are shown in ORGM´s mod...

Is there anything I can do for now, besides getting used to invisible guns?

Thnx in advance

Candyflip · June 25, 2015

Version of the mod? or the version of the game? Game version: 31.13 on steam, Version: ORGM 1.235 And Version: Lua extendor v1.01

(sorry for late reply but the problem still persists) Thanks for the relpy too, really wanna get this to work.
