Launcher Core Module

npm version Downloads Install size npm Build Status

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 "@xmcl/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 "@xmcl/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 "@xmcl/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 } });
