Guide

[space2pacman]

Please write a guide on how to launch a project.

I don't have time for a full guide as I've been so tired after work to the point where it's been months I've touched my computer after work but installation is actually pretty straight forward.

1. Download C4 & install it. I know the readme says C3 but it's been a pain finding properly working C3 client & L2J server so I've moved to C4 for development as it's actually quite easy to backport to C3 as most of the C4 features are behind their own feature flags.
2. Clone the repo to stable branch, this is couple years of development behind the core_integration but much easier to run
3. symlink the installed game dir to lineag2js/assets-c4/ so that it's lineag2js/assets-c4/system/, lineag2js/assets-c4/staticmeshes/, etc.
4. npm install
5. npm start
6. localhost:8080
7. add/change/remove sectors that are loaded from src/core.ts, keep in mind stable lacks some asset loading optimizations so it takes longer to load assets when compared to core_integration feature branch and even then I'm not worried about performance/loading times etc. as my goal is to just decode the assets properly at the moment before actually building the engine

meanwhile core_integration is more accurate at loading certain assets but requires https://github.com/realratchet/l2js-core/tree/client_interop this specific branch and even then a lot of stuff hasn't even been ported to this two project hierarchy and probably not even in a working state at the moment

i don't remember if stable branch has physics for loading player characters but it definitely has functioning skeletal animations

I was sucessfully able to clone the project in it's current state. Can't help with more.

When running on Windows out of the box, the error above (Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'has')) still persists. What can I run it on and how?

Linux? Linux version?

asset-loader.js 189

function getPackage(allPackages: Map<string, Map<SupportedExtensions_T, UPackage>>, pkgName: string, impType: SupportedImports_T): UPackage {
    const packages = allPackages.get(pkgName.toLowerCase());
    const validExts = impToTypes.get(impType);

    let pkg: UPackage = null;

    for (const ext of validExts) {
        if (!packages.has(ext)) continue; // this Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'has')

        pkg = packages.get(ext);
        break;
    }

    return pkg;
}

Honestly no clue, it's possible it could be windows related. I'm using ubuntu 24.04 but realisticly any distro should work.
