Launcher Core Module
Version made for Lumina projects. Original credits goes to Voxelum/minecraft-launcher-core-node
Provide the core function to parse Minecraft version and launch.
Usage
Parse Version JSON
Parse minecraft version as a resolved version, which is used for launching process. You can also read version info from it if you want.
import { Version } from '@createlumina/core';
const minecraftLocation: string;
const minecraftVersionId: string;
const resolvedVersion: ResolvedVersion = await Version.parse(minecraftLocation, minecraftVersionId);Diagnose
Get the report of the version. It can check if version missing assets/libraries.
import { MinecraftLocation, diagnose, ResolvedVersion } from '@createlumina/core';
const minecraft: MinecraftLocation;
const version: string; // version string like 1.13
const resolvedVersion: ResolvedVersion = await Version.parse(minecraft, version);
const report: MinecraftIssueReport = await diagnose(resolvedVersion.id, resolvedVersion.minecraftDirectory);
const issues: MinecraftIssues[] = report.issues;
for (let issue of issues) {
switch (issue.role) {
case 'minecraftJar': // your jar has problem
case 'versionJson': // your json has problem
case 'library': // your lib might be missing or corrupted
case 'assets': // some assets are missing or corrupted
// and so on
}
}Launch Game
Launch minecraft from a version:
import { launch } from '@createlumina/core';
const version: string; // full version id, like 1.13, or your forge version like, 1.13-forge-<someForgeVersion>
const javaPath: string; // java executable path
const gamePath: string; // .minecraft path
const proc: Promise<ChildProcess> = launch({ gamePath, javaPath, version });Detach from the parent process. So your launcher's exit/crash won't affact the Minecraft running.
const proc: Promise<ChildProcess> = Launcher.launch({
gamePath,
javaPath,
version,
extraExecOption: { detached: true },
});
