Description
SWAP MECHANIC. On each swap cycle, all living players randomly exchange positions with each other (a random derangement so nobody stays in place, works across dimensions including Nether). Show a title warning SWAPPING IN 5 with a countdown at 5 seconds before each swap, play a warning sound, then swap. Show the actionbar at all times with time until next swap and each player’s remaining lives. Swap preserves inventory, only positions swap. ITEM ROULETTE. Every 45 seconds (configurable), each living player receives 3 random special items placed in hotbar slots 7, 8, 9 (the last three slots). These three slots are RESERVED for choice items only: give every choice item with the minecraft item_lock component set to lock_in_slot so it cannot be moved or dropped, and run a per-tick inventory watcher that removes any normal item a player tries to place into slots 7, 8, or 9 and returns it to the first free slot or drops it at their feet. The player chooses ONE choice item by selecting it in the hotbar and right clicking / using it (detect via the itemUse event, which is tap or long-press on touch devices). On use, the used item’s effect activates immediately and the other two choice items are deleted. If the player does not choose within 30 seconds, all three vanish. Each special item is a renamed vanilla item with lore text describing its effect. Choice items must never be usable for their normal vanilla function, only trigger the custom effect. IMPLEMENT AT LEAST 40 SPECIAL ITEMS in a weighted pool, mixing helpful and harmful. Examples to implement: Nuke (spawn a cluster of 30 TNT with 3 second fuse on a random opponent), Summon Warden (spawn a warden next to a random opponent), Nether Yeet (teleport a random opponent to a random Nether location), Anvil Rain (spawn 15 falling anvils above a random opponent), Swap Now (force an immediate position swap), Lava Pool (place a 3x3 lava pool under a random opponent), Blindness Curse (give all opponents blindness and slowness 20 seconds), Creeper Squad (spawn 5 charged creepers around a random opponent), Sky Launch (launch a random opponent 80 blocks up with slow falling removed after 3 seconds), Full Diamond (give self full diamond armor and sword), Golden Feast (give self 8 golden apples), Heal Up (full health and 30 seconds regeneration), Speed Demon (speed 3 for 60 seconds), Invisibility Cloak (invisibility 45 seconds), Ender Escape (give self 3 ender pearls and teleport 100 blocks in a random direction), Fortress (build an instant 5x5 obsidian box around self), Bee Swarm (spawn 10 angry bees on an opponent), Zombie Horde (20 zombies on an opponent), Cobweb Trap (surround an opponent in cobwebs), Hunger Games (all opponents get hunger and weakness), Ghast Above (spawn 2 ghasts above an opponent), Lightning Strike (strike an opponent with 3 lightning bolts), Random Teleport (teleport an opponent 300 blocks in a random direction), Ice Age (freeze area around an opponent into ice and powder snow), Steal (take a random item from an opponent’s inventory). Fill the rest with similar chaotic effects using vanilla mechanics only. LIVES AND WIN CONDITION. When a player dies they lose a life, a global chat message announces it with remaining lives, and they respawn at a random location 200 blocks from their death point with a 10 second grace period of resistance. When lives reach zero they become a spectator. When one player remains alive, display a victory title to everyone with fireworks at the winner, play sounds, announce final standings in chat, then reset everyone to the lobby state after 15 seconds. Include a !stop command for the host to end the game early and a !ds command to reopen the settings menu between games. All timers must pause correctly if the world is suspended and must not desync. No dedicated server dependencies, must run on a Realm or LAN world.

Ultimate Death Swap
Quickstart
- In the lobby, open the Swapstorm Royale settings menu. Choose Start default game for a standard round, Start quick mode for faster swaps and roulette, or Testing to try the special items.
- Standard games are for 2–6 players. Each player starts with a small kit: a stone axe, stone pickaxe, iron ingots, and oak logs. Players begin where they are.
- Watch the action bar for the next swap, roulette, enchantment surge, and your remaining lives. Before a swap, a SWAPPING IN title counts down from five seconds.
- When roulette gives you three items, choose one from hotbar slots 7–9 and use it. Helpful choices affect you; harmful choices let you select a living target using the glass-pane target picker.
- Try to stay alive: the last living player wins. You start with three lives in most modes; Hardcore starts with one.
Choice items arrive during a round—there are no recipes to craft them. In Testing mode, browse the roulette items from your inventory and use them to try their effects.
Overview
Ultimate Death Swap is a multiplayer survival contest built around position swaps and a weighted roulette of helpful and harmful effects. Swaps exchange living players’ positions, including across dimensions, but do not exchange inventories.
In the standard game, PvP is disabled until the first roulette arrives, then turns on. Roulette choices are temporary: you have 30 seconds to use one before all three disappear.
What It Adds
- Position swaps: Living players are randomly assigned one another’s positions. Your inventory stays with you.
- Item roulette: Each round gives each living player three distinct, weighted choices in the last three hotbar slots.
- Lives and elimination: Death costs a life. At zero lives, you become a spectator.
- Testing mode: Lets players browse and try roulette effects without a regular match’s win condition.
How To Use
Roulette choices
Use a choice item from hotbar slot 7, 8, or 9 to trigger it. These slots are reserved for choices, so ordinary items placed there are moved to another free slot or dropped at your feet. Choice items cannot be moved or dropped, and using them triggers their special effect—not their usual vanilla function.
Helpful choices activate on you. For a harmful choice, use it first, then use the glass-pane target picker to select a living player. The other roulette choices are removed once your selection takes effect. If you wait 30 seconds without choosing, all three vanish.
Settings and host controls
The settings menu opens in the lobby. Its match presets are:
| Mode | Lives | Swap interval | Roulette interval |
|---|---|---|---|
| Default | 3 | 75 seconds | 60 seconds |
| Quick | 3 | 45 seconds | 30 seconds |
| Hardcore | 1 | 75 seconds | 60 seconds |
| YouTuber DS | 3 | 5 minutes | Randomly every 32–48 seconds |
Testing mode is also available from the menu and can be started with any player count.
The host can end an active game early with /scriptevent swapstorm:stop. Use /scriptevent swapstorm:ds between games to reopen the settings menu.
Crafting And Obtaining
Roulette items are supplied during a match; they are not ordinary craftable gear. Regular matches start the roulette on the selected interval, then provide choices at subsequent intervals. Testing mode supplies a browseable inventory of roulette items.
Abilities And Mechanics
Swaps, lives, and victory
The action bar shows the time until the next swap and roulette, the next enchantment surge, and your lives. Swaps are preceded by a five-second title countdown and warning sound. An occasional enchantment surge also empowers an item in a living player’s inventory.
A death costs one life and is announced in chat with your remaining lives. If you still have lives, you respawn at the round’s shared spawn with 10 seconds of resistance. At zero lives, you become a spectator. When one player remains alive, the game announces the winner and final standings, celebrates with fireworks, and returns players to the lobby after 15 seconds.
