[Overview] Sponge Core

[IDragonfire]

The forum is growing and it is hard to find “SpongeCore” discussions. Most threads are about “features” of Sponge.

I try to manage a list of the core discussions on the forum.

For the current development stage take a look at the issue tracker: http://issues.spongepowered.org/

SpongeCore Discussions

Using an Rx-inspired event system

It may be too early to talk about this, but I still think a useful discussion to have. I think we can all agree that the Bukkit and Forge event systems are both verbose and somewhat outdated. I would propose that we switch to a system based on Rx, because it means less complexity and also more power. By Rx I mean Rx-inspired, we don’t have to use RxJava. Here’s an example of listening to an event: server.events.playerMove().on(new Callback<PlayerMoveEvent>() { public void call(PlayerMoveEven…

SPONGE-2: World Generation API

Disclaimer I am nobody important, this document is not official in any way. It contains my ideas for the World Generator API for the Sponge project. Please yell at me if anything is incorrect. Also I would love to hear your suggestions and input too! If I’m stepping on anyone’s toes, let me know and I’ll take this down ASAP! NB: It’s important we keep this simple, otherwise it’ll be impossible to maintain. YouTrack Issue http://issues.spongepowered.org/youtrack/issue/SPONGE-2 Fork I’ve …

Formal threading model for the API

The MC server has basically a single “main” thread and lots of other minor threads. Almost all events occur on the main thread (except those that don’t) and similarly almost all methods in the API had to be called from the main thread (again except those that didn’t). In future versions, worlds might be handled on their own thread. Glowstone already does this and there has been suggestions that MC might go that way too. If we say that calling any API method from inside an event handler is al…

The event-system implementation, Monitoring and you

I hope that I can write more meta-related topics in this forum, otherwise I will copy my question to github. As all the issues regarding the Monitoring state of events come up, I thought about adding something to those orders. What if an Order actually had a flag if the cancelled state is allowed to be modified or not? The implementation (In this case “Sponge”) could then check if one of the listeners modified the state, give out a warning in console and set it back to its previous state. Tha…

NBT Tag support

I believe it would be very helpful to have native support for NBT Tags and other things built into the API. A weakness in the Bukkit API was their inability to support NBT properly that led to convoluted libraries and made it a pain to efficiently store items. I’m sure others can touch on this more, just something I was feeling that needed to be addressed.

Command API

Since it seems it has been somewhat suggested that I do the command API, here’s what I got. First off, I have Intake, which is a command processing library I spun off from WorldEdit 6. It’s usable, but it’s not finished by any means. The original pull request to pull it into WorldEdit is over a year old, never went through, and eventually was salvaged for a newer branch. That said, it supports annotations, but usage of it is optional. An example of annotation usage is: @Command(aliases = "age…

Persistent metadata API

When I added IMetadatable and the metadata API to Bukkit, I intentionally left out persistence. This was a mistake. I would like to propose a mechanism for attaching named metadata to entities that persists in the underlying world store. This could be implemented with NBT or some other means.

All About Minecarts

Hey! What would everyone love to see in a minecart API that would make it just the best thing ever? My thoughts: Speed and max speed adjustments Momentum/inertia changing Furnace minecart shenanigans More types of blocks in carts Anything y’all can think of!

Java Persistence API / Ebean Server Support?

I used Ebean Server of Bukkit a lot. (Java Persistence) Is a similar system planned? Ebean? Hibernate?

The official Java style and convention for Sponge

We’ve established some more complete and official style guidelines for Sponge. It is largely following in the footsteps of Google’s Java style. This replaces the rules previously mentioned in the Contribution Guidelines document.

DB connection part of API or a separate Plugin?

I’d like to see a ‘universal database’ type API. Something were I can set up the connection parms to my database (mySQL, SQL Lite, or whatnot) and then this be used by all other Sponge plugins. This way if I move my db or set up a new one I don’t have to remember which plugins have their own db config section.

[Dev] Config API

[Dev] Config API - #5 by IDragonfire I misunderstand the gdoc table … sk planned to use: https://github.com/typesafehub/config It is already shaded into Forge. old Post: @sk89q announced that they need help with some packages. Today I want to talk about the “util.config” one. #I want not talk about the format I want to talk about the API and usage. sk89q want a typesafe config system. I prefer a annotation system, e.g. DragonAntiPvPLeaver/DAPL_Config.java at master · IDragonfire/DragonAn…

[Dev] Is there a need for an OfflinePlayer

Just wondering what the community thought about this. Please give reasons to why you think we need an OfflinePlayer

[Dev] InventoryAPI

BASIC InventoryAPI It is not more then an itemholder. We should hide the index structure if minecraft changes the internal system. Atm I have two designs. Bukkit like system, but with SlotType instead of int’s Component based system (each Inventory have ComponentInventories, e.g. a PlayerInvebtory has the Components: Equipment, Backpack, Crafttable, Hotbar) InventoryUtil - Syntax Sugar Give you the possibility to do cool stuff, e.g. to add Item to existing Stacks and return non fitting on…

Block data / state / enchantment API

I’m playing with the following way to work with blocks, block data, and enchantments. Note: Location below is basically Bukkit’s Block and Location in one. It will contain doubles but they will be rounded to ints when accessing block data. The plus is that you do not have to convert between Bukkit Blocks and Locations. Block below is not Bukkit’s Block. It’s MCP/Forge’s Block, which is the type of block (i.e. Bukkit Material). Location below is basically a convenience class. You can do eve…

Sponge's Way Of Logging

Now, Im a bit fussy when it comes to logging. I guess its based on Forges’s way of logging which is just stupid. What is the point of this? [12:33:37] [Server thread/INFO] [net.minecraft.server.dedicated.DedicatedServer] : Loading properties Surely the Sponge Team could condense it to: [12:33:37] [Server thread/INFO] [Sponge] : Loading properties Although, I have the feeling that its something to-do with class names, and if it is, Bukkit didn’t have all that [net.minecraft.server.dedica…

Action API Concept

An action is something that the server tells the client to do once and never worries about from the server side again. They’re reasonable to perform over groups of players, such as the whole server, a whole world, a radius around a location, a specific Extent, a single player, or some other grouping. The goal of defining Actions is to avoid creating many copies of methods on each player set (see above) which may want to make available these actions to avoid the need for manual looping in plugin…

Architecture overview

I posted this on the “Learn more” document, but I imagine that not everyone has seen it. Here’s a graphical overview of what Sponge “is.” The general overview [image] What we build [image] How we maintain cross-version compatibility [image] What’s open source [image] Where Bukkit fits [image] Where Forge mods and hMod plugins fit [image]

Hard to decide if “Core” Discussions

API: Custom Blocks

About This has been an idea of mine for quite some time; ever since seeing Spoutcraft I felt like we were almost there, we were just missing some tiny little glue to make everything Just Work. Now that 1.8 and Sponge are here, everything kind of clicked together. Being involved with Sponge has given me such unprecedented access to iconic modders that I could pull the last few strings to make this work. Custom blocks that work for clients that support them, and replacements for clients that don’…

Built-in Localization support and message formatting

I think localization is important. I’m from germany and there are many servers with german chat, and plugins should be localized as well. It would be nice to have a simple system for translation and maybe even a unified message (color) formatting system, making translation of big text-heavy plugins simple. I thought about it when making Bukkit plugins, and i think it should work like gettext. The good thing about it is that the code is still readable, without placeholders for messages like “PL…

Make all server messages configurable

I love the fact that bukkit and spigot let you customize some server messages (the Unknown command one, the stop server one, whitelist, etc). I hope Sponge would allow to custom every single server message. Thanks
