About this project
What does BSP CORE add?
BSP-Core
The mod at the heart of the Build Secure Protect modpack. Build a base, secure it, protect your Shatter Totem, and go and take everyone else's! Every block, machine and screen in here is about the totem: keeping yours, stealing theirs, or getting rich enough to upgrade it. This page runs in the order you meet things: your first minute, the road to a strong totem, the money, the plasma, the raids, your team, and then what the server owner sets up behind it all.
- Minecraft 1.20.1, Forge 47 or newer, Java 17. Needed on the client and the server.
- Plays well with JEI or EMI (every recipe and machine job), Patchouli (the in-game guide book), Jade (block info), any RF mod (power for the machines), LuckPerms (ranks on kits), and the pack's crushers: Mekanism, Create, Thermal, Ender IO, Railcraft, Integrated Dynamics and Electrodynamics all turn BSP ingots into dust.
- Made for the other BSP mods: BSP-Teleport, BSP Region Guard, BSP-RankUp, BSP-InventorySync and BSP-Velocity Additions all plug into it. It runs fine without them.
Your first minute

The moment you join you get a Shatter Totem, the guide book and 500 Shatter Pieces in the bank, and that is the only way to get a totem. Place it and it projects your base powers in a cube around it. Carry it and it powers you. Keep it somewhere clever, because anyone who finds it can stand beside it for five minutes and walk off with it, powers and all. You get a warning the second they start. There is no power, block or trick that makes a totem safe, and we are never adding one. You cannot hide it in a storage system either: it comes straight back out. If you crash with it in your hands it is placed where you stood, and it is back in your hands when you return, as long as nobody took it in between.

Twenty-eight powers on six paths, bought with Shatter Coins and XP. Carried powers work while the totem is on you, Base powers come from a placed totem, and Raid powers help you take someone else's. Up to eight friends on the ACCESS tab can pass your Alarm and Ward and use your machines, and your whole team can do all of that and upgrade your totem too.
The road ahead

Three metals, each slower than the last, and a machine for every step. That is the whole thing in one picture; the next sections walk it top to bottom.
Ores

Tetrium: where you start

Tetrium is everywhere and it is quick. A crucible, a forge, and you are making plates, chassis and circuits: the parts every later machine is built from. Hang on to the slag, it becomes the bricks in every chassis.

Illyrium: slow and worth it

Illyrium comes one nugget at a time: smelt the ore in lava, crush the dirty ingot, wash the dust, alloy it back. Nine nuggets and the best part of an hour make one ingot. The dirty metal is useful on its own: it presses the dies that build the coin factory and the centrifuge.

Magnatite: the metal in between

The Magnetic Centrifuge separates the ore, and with a coil in it charges the ingots: a gamble that gets better with every layer you stack on top. Charged Magnatite and Carbon Dust go into every cable, battery and plasma block.

Shatter Coins: real time, no shortcuts

Coins buy totem tiers and powers, and you press them yourself, in real hours: 8 for Copper, 96 for Illyrium. The factory keeps pressing while you are offline, and a Coin Vault pays interest on what you keep in it. Rivals can pick the vault for a quarter of the coins.

Shatter Pieces, the bank and the shops

Pieces are the everyday money, and they are never an item: nobody can steal them. Every player has a bank account. Walk up to a Shatter Bank, the ATM the server puts at spawn, and you can pay anyone by name, read your log, and deposit coins. Coins kept in the bank are safe from thieves and stay coins, or you convert them to pieces, a thousand a Copper. A Portable Banker in your pocket does the same anywhere, and once it has unlocked the Shopping Network, every shop flagged for it opens from wherever you stand. Rent a Safety Deposit Box by the day for the things you cannot afford to lose; a totem is the one thing it will not take.

Shops are wherever the server puts them: a Vendor Post with a figure of the server's choosing, a Market Stall in one of eight styles, or a Stall Display floating the wares above it. Every shop is a page of cards: the item, buy in gold, sell dim, a stock badge and a star for instant buy. Left click buys, right click sells, shift-right sells every full stack. Stock can be per server or per player and comes back on a timer, rotating shops change what is on offer, and special offers cut prices until a time.

With BSP Region Guard on the server, the Land Office sells land. Its screen is a map of the ground around you drawn from the terrain: plots for sale in amber, open ground dashed, your own claims in green, the outline you drew with the wand in white. Click a plot for its size and price, then BUY, ENLARGE or GIVE UP.
Wave Plasma: your totem, on tap

A placed totem gives off Wave Plasma. Pipe it and your base powers appear wherever the cable ends. Feed it into a Plasma Injector and a machine runs up to three times faster. Bottle it in a battery and your base keeps running while the totem is away, or stolen. Put a cell in the Wave Emitter and carry your powers without carrying the totem. A tank holds millions of mB of it for the lean times, and remembers which powers the plasma carried.

Plasma across worlds

Seven Accelerator Frames round an Accelerator Intake, standing up with the middle empty, and you have a Plasma Accelerator: an octagon with a copper track, eight coil heads and a black sphere turning in a brass cage. Write a Link Card on it, put the card in a Decelerator Core in any other world of the server, and the plasma hops across, powers, access list and all. The port behind the core sends it on to whatever its cables reach, so a Nether outpost runs on an Overworld totem and keeps its chunks loaded through the link. Both ends drink RF; without it nothing moves. Right-click the intake for the Worlds board, one column per world, with every link lit while plasma passes.

Decoys, traps and the compass

A Decoy Totem looks like the real thing to everyone but you, pulls rival compasses toward it, and goes off like a trap when they try to steal it. Range coils, five kinds of charge, an amplifier and reinforced casings go in its sockets. Your own Totem Compass points home, or for a while at the nearest rival.

Teams

One team per player, a leader and up to five members, a name and a colour. Teammates have full access to each other's totems: open the panel, buy upgrades and raise the tier (the buyer pays), change chunks, use the plasma machines and projectors, see through the cloak, walk through the Ward and Alarm. Nobody in a team can steal from it, and the compass ignores teammates' totems. The screen opens from the TEAM tab on any totem of yours or a teammate's, from the TEAM button above your inventory, or from a key you bind.

Inviting takes one click on a name, and the invite lands as a card at the top right with two keys and a minute to answer, a chime, and a clickable line in chat for a player busy in a screen.

TEAM CHAT sends what you type to the team until you switch back, with a pill above the chat while it is on; /t sends one line. Everything said goes on the team's board, so members who were offline read it when they are back, under the leader's pinned note. On a network the team is one team on every server, and the member list says which server a teammate is on. With BSP-Teleport installed there is a TELEPORT key on every online teammate's row.
Kits

Kits are bundles the server hands out: at your first login, as a reward when you reach a rank, or from the kit browser behind the KITS button above your inventory. Every kit is a card. A ready one has REDEEM on it. One you took lately sits grey with the time until it is ready again. A locked one says why: the rank to reach, with your own step marked on the ladder, the server to be on, the price against your balance, or the slots you need to free. A kit given to you that did not fit, or came while you were away, waits in violet with TAKE IT. Nothing is ever lost: a kit never goes into an inventory that cannot take it, and the price is only charged after that check.

Click a card's picture to see what is inside, with the counts, and every condition ticked or crossed.
Scores, seasons and the screens

Every totem you own scores by its tier, so stealing and upgrading both move you up. Score Screens at spawn show the live leaderboard, the season's rules and the prizes, and can carry boards from the other BSP mods and turn through all of it, page by page. When a season ends the top three take the prizes, every totem is removed and everyone starts again with a fresh Tier I totem; prizes wait for you if you were offline.
For server owners

- One config file,
serverconfig/bsp_core-server.toml: every cost, time, range, limit and price, the bank, the shops, teams and kits. - Admin Rack, or
/bsp admin: every player's totems, position and vault at a glance, teleport and reset, the season end that pays the top three and hands everyone a fresh totem, decoy ranges, chunk loading, and the KITS tab./bsp totem wipe <player>gives a test account a clean slate. - Shops are yours to build.
/bsp shopopens the Workbench: shops, pages, cards, prices, stock, hours, styles and the network flag, all in a screen. Vendor Posts, Market Stalls, Stall Displays, the Shatter Bank, the Safety Deposit Box and the Land Office are admin-placed blocks: nobody mines, pushes or blows them up.

- Kits are made in the panel. The KITS tab lists them; the editor has the kit's slots, FROM HAND and FROM INVENTORY for enchanted items, an item browser with search and a chip per mod, and every rule as a row of chips: when it is given, whether it is in the browser, once or every so often, the price, the LuckPerms ranks (RankUp's ladder, when RankUp is installed), the servers. TEST ON ME tries it on you; GIVE TO hands it to a player.

- Anti Totem Block: keeps totems and chosen machines out of spawn, hubs and arenas, and tells BSP-Teleport where homes and teleports are not allowed.
- Networks: MySQL or MariaDB shares totems, limits, the leaderboard, vault totals, seasons, steal warnings, bank accounts, deposit boxes, shops, teams and kits across every server; add Redis and all of it is live. A kit taken on one server is taken everywhere; a team made on one exists on all.
- The other BSP mods reach everything through
com.mrgregles.bsp_core.api: totems, steals, seasons, teams, kits, the bank, zones and transfers between servers. BSP-RankUp hands out kits as rank rewards, BSP-Teleport moves teammates and lands Recall across servers, Region Guard sells the land, BSP-Velocity Additions carries the chat between servers.
Status
1.4.0 is the current release: the bank and shops, plasma across worlds, teams, kits and the boards on the Score Screens, on top of 1.0. Every picture on this page is drawn from the mod's own models, textures, recipes and screens, so what you see is what you get in game.
