Twitch Spawn

Let your Twitch viewers spawn mobs in your singleplayer world with Channel Points.

Twitch Spawn connects to Twitch through the official API (OAuth Device Code flow — the mod never sees your password) and listens to Channel Point reward redemptions. Each reward you create on Twitch can give you a Mystery Egg, spawn a random mob, or spawn a random passive animal around you.

Not affiliated with or endorsed by Twitch. Twitch is a trademark of Twitch Interactive, Inc.

Features

• Mystery Egg – a custom item whose mob is hidden. Right-click the ground to hatch a random mob from your list.
• Egg on a spawner – use the egg on a mob spawner to set it to a random mob.
• Mystery Spawn – a reward that directly spawns a random mob from the "Mystery" list around you.
• Animal Surprise – a reward that spawns a random passive animal from the "Passive" list around you.
• Any mob, any mod – an in-game Mobs screen lists every mob of your modpack, with separate ON/OFF switches for Mystery and Passive. Filter by type (hostile / passive), by mod, or search by name. Bosses are unticked by default (best effort – please review).
• Blacklist – mobs that can never be spawned (Ender Dragon, Wither, Giant, Warden by default).
• Direct rules – you can also map any reward title to any specific mob and a count.
• Safety limits – spawn distance, max alive mobs, max per redemption, minimum delay between spawns, per-viewer cooldown, request expiry, duplicate protection.
• Stream mode – hides the Client ID, the Twitch account and the pairing code inside the game.
• Viewer names – spawned mobs can carry the viewer's name.
• Test buttons – try every rule without Twitch.
• Auto-reconnect after network drops, Twitch server migrations and expired tokens.
• Twitch network traffic runs off the game thread; spawns happen on the server tick.

Requirements

• Minecraft 1.20.1 with Forge 47.4.10 (Java 17).
• A Twitch account that can use Channel Points rewards (Affiliate or Partner).
• A free Twitch application Client ID created by you at https://dev.twitch.tv/console (public client; no secret needed).

Quick start

1. Install the mod in your mods folder.
2. In a singleplayer world, open the mod with the K key (or Options → Twitch Spawn).
3. Settings → paste your Client ID.
4. Connect to Twitch → open the page shown, type the code, authorize. The mod only asks for the channel:read:redemptions permission.
5. On Twitch, create Channel Point rewards whose title exactly matches a rule (default: Oeuf Mystère, Spawn Mystère, Animal Surprise). Titles are editable in the Rules screen.
6. Pick which mobs are allowed in the Mobs screen.

Settings are stored in config/twitchspawn.json; the Twitch token in config/twitchspawn-token.json (never share it).

Good to know

• Singleplayer only. Spawns happen in the world of the player who owns the singleplayer game. Dedicated servers are not supported.
• Only Channel Point rewards trigger spawns (no bits, subs or donations).
• Redemptions stay pending on Twitch; the mod neither fulfills nor refunds them.
• The in-game interface is currently in French.
• Hostile mobs are refused on Peaceful difficulty.
• Spawning many modded mobs can affect performance – use the limits.
• The mod has not been tested on every modpack; if something breaks, please report it with your latest.log.

Privacy & security

• Official Twitch API only; no password, no chat access, a single read-only permission.
• Disconnect from the mod, or remove it at https://www.twitch.tv/settings/connections.
• Turn Stream mode on before streaming so nothing sensitive appears on screen.
