ConditionalVideos

✨ Overview

ConditionalVideos plays custom videos when specific in-game events are detected — first joins, deaths, kills, advancements, item milestones, scoreboard thresholds, and more.

It runs on both client and dedicated server: the server detects conditions and tells the right client what to play, while the client handles the actual playback. This makes it a good fit for servers, story maps, quest packs, and roleplay setups where cinematic feedback improves immersion.

Highlights

• A dozen trigger types, from firstJoin to scoreboard thresholds and mod-defined custom conditions.
• Per-condition playlists with crossfade/cut transitions, looping, text overlays, per-clip volume, and timed cuts.
• Broad source support through WATERMeDIA — local files, direct URLs, YouTube in high quality, Twitch/Kick clips, TikTok, SoundCloud, and many more.
• A playback queue so overlapping triggers play in sequence instead of cutting each other off.
• A small public API for other mods (see the project Wiki).

🧩 Compatibility & Requirements

| Minecraft | Loaders | Java | |---|---|---| | 1.20.1 | Fabric, Forge | 17+ | | 1.21.1 | Fabric, NeoForge | 21+ | | 1.21.11 | Fabric, NeoForge | 21+ | | 26.1.2 | Fabric, NeoForge | 25+ | | 26.2 | Fabric, NeoForge | 25+ |

> On 26.2 the game can run with either renderer. Videos play on both, but support for the Vulkan > renderer is experimental — Minecraft ships it as an opt-in preview, so OpenGL remains the safest > choice if you hit trouble.

Required (client side):

• WATERMeDIA: Multimedia API — v3.0.0.23+
• WATERMeDIA: Native Binaries — v3.0.0.6+
• Fabric API — any (Fabric Only)

Config files:

• config/conditionalvideos.json — client / singleplayer rules
• config/conditionalvideos-server.json — authoritative rules for a dedicated server
• config/conditionalvideos-common.json — client playback behavior (also read by servers for the synced options)

In multiplayer the dedicated server owns the config, ships any local video files to clients automatically (cached and reused on reconnect), and URLs are streamed directly by each client. Treat conditionalvideos-server.json as the source of truth for server content.

🎯 Supported Conditions

Each condition is configured with a playlist. Simple conditions use a single config key; keyed conditions are a map of id → condition.

Simple (single key):

• firstJoin — plays when the player enters the world/session. Always prioritized: if other conditions fire during world load, firstJoin plays first and the rest queue behind it.
• playerDeath — fallback cinematic for any death.
• totemUsed — a Totem of Undying saves the player.
• bedSleep — the player starts sleeping in a bed.

Keyed (map of id → condition):

• deathByEntity — death by a specific killer entity ID (overrides playerDeath).
• entityKilled — the player defeats a configured entity ID.
• advancementCompleted — a configured advancement is completed.
• dimensionChanged — the player enters a configured dimension.
• itemObtained — the player obtains a configured item (pickup, craft, or smelt result).
• itemCrafted — a configured item is actually crafted (independent from itemObtained).
• recipeUnlocked — a configured recipe is newly unlocked in the recipe book.
• scoreboard — a player's score on an objective satisfies a comparison (see below).
• custom — no built-in detector; fired only by the public API or the play command.

Scoreboard comparators

Each scoreboard entry compares a player's score against a value using a comparator:

| comparator | Fires when | |---|---| | equal | score == value | | less | score < value | | greater | score > value | | lessOrEqual | score <= value | | greaterOrEqual | score >= value (default) |

It is edge-triggered: a satisfied comparison fires once and only re-arms after it turns false and crosses back to true. Because scores persist with the world, a comparison already satisfied before logout does not re-fire on rejoin.
