Shared Potions Mode

​

Overview

• Duration-based effects (Speed, Strength, Poison, etc.) are synced to all players immediately
• Instant effects (Instant Health, Instant Damage) are applied only to the closest player to prevent multiplication
• Both positive and negative effects are shared
• Effects from all sources are synced (potions, splash potions, mob attacks, beacons)

​

How to Enable

1. Run /chaos to open the Chaos Modes GUI
2. Click on the Glass Bottle/Dragon Breath icon (“Shared Potions Mode”)
   • Glass Bottle = Disabled
   • Dragon Breath = Enabled (blue color)
3. Click the emerald “Confirm” button
4. Start a new run with /start

Advanced Mechanics

​

Splash Potion Handling

1. All players in the splash radius are tracked
2. The system calculates the centroid (center point) of all affected players
3. The player closest to the centroid receives the instant effect
4. Duration effects are synced to everyone
5. Health changes propagate through the normal Soul Link health sync

​

Synchronization Details

• Uses a isSyncing flag to prevent infinite loops
• Tracks recently synced effects to prevent duplicates
• Processes instant effects at tick-end to avoid race conditions
• Clears tracking data after each tick

Code Reference

public static boolean onEffectApplied(ServerPlayerEntity player, 
        StatusEffectInstance effect, Entity source) {
    if (isSyncing) {
        return true; // Allow synced effects through
    }
    
    if (!settings.isSharedPotions()) {
        return true; // Shared potions disabled
    }
    
    // Handle instant vs duration effects
    if (isInstantEffect(effectType)) {
        return handleInstantEffect(player, effect, runManager);
    }
    
    return handleDurationEffect(player, effect, runManager);
}

​

Instant Effect Types

public static boolean isInstantEffect(RegistryEntry<StatusEffect> effect) {
    return effect.getKey().equals(StatusEffects.INSTANT_HEALTH.getKey())
        || effect.getKey().equals(StatusEffects.INSTANT_DAMAGE.getKey());
}
