WorldInfo modification

[ci010]

Currently, we only support WorldInfo reading.

Though, we want the basic level of modification on the WorldInfo. (We already have a strong NBT support, which makes this much easier)

This is the current WorldInfo class. I only picked some important (I think) properties.
Feel free to support more properties you believe is fine to view/modify.

The readonly property don't need to write to nbt (of course).
The public property will be write into nbt.

export class WorldInfo {
    constructor(
        // readonly filename: string,
        public displayName: string,
        readonly sizeOnDisk: Long,
        readonly lastPlayed: Long,
        readonly gameRule: GameRule,
        readonly dataVersion: number,
        readonly version: { snapshot?: number, id: number, name: string },
        readonly generatorName: string,

        public difficulty: number,
        public gameType: GameType,
        public isHardCore: boolean,
        public enabledCheat: boolean,
        public spawnPoint: Pos3,

        public borderCenter: Pos2,
        public borderDamagePerBlock: number,
        public borderWarningBlocks: number,
        public BorderSizeLerpTarget: number
    ) { }
}

说了那么多其实就是让玩家能有直接改动世界设置的能力2333level.dat里也存了玩家的数据，如果以后有精力甚至可以改玩家状态和背包数据等……但无论如何这玩意写起来比较枯燥

Maybe u need a object <-> NBT convention utility.

Sorry if this is a stupid question: why is filename commented? Thanks

Ah, this is really an old post. At that time, I decided to stick with the Minecraft original spec, which means the lib should not wrap another layer of interface to those Minecraft data.

Therefore, current Save/World reading is follow the original NBT structure and naming -- no capital character transformed.

Back to question, at that time I somehow decide to refactor the module, and the fileName is not in the level.dat. Therefore, I comment it out.

For the current status, you can refer the packages/world/index.ts. It's now load by WorldReader#getLevelData, and you will get directly a NBT data frame, no extra naming transform. The mc wiki will help a lot in dev.

I kind of plan to make the WorldReader be able to read region data (chunk) in these two months, for both old chunk format (version < 1.13) and new chunk format (version >= 1.13). The testing data is kind of ready... I'm not sure when I'll finish this.
