v1.6.2 - The Harvest & Persistence Update

⛏️ Harvesting Mechanics and the XP Harvester

• Right-Click Harvest:
  • Mature crops can now be harvested by right-clicking. The block resets its age (age=0), simulates a drop (minus one seed) and plays a sound without the need for replanting. Left-clicking works as usual.
• AoE Hoe:
  • The XP Harvester Level 2+ enchantment allows you to harvest crops across an area (limit: 3 blocks per click).
• Limited VeinMiner for ores:
  • XP Harvester Level 2+ on a pickaxe breaks a chain of identical ores (hard cap: 6 blocks) .
  • Balance: For every block broken in the chain, the tool’s durability is fairly deducted, exhaustion is accrued and experience is generated. Exploits involving infinite durability are prevented.

🔥 Kill-Streak Persistence

• NBT Storage:
  • Kill streaks are no longer reset when logging off the server. Data is written directly to the player’s NBT (lifexp_kill_streak and lifexp_last_kill_time).
• AFK Timeout:
  • A time limit has been introduced. If more than 5 minutes (300,000 ms) elapse between mob kills, the streak is automatically reset. The reset upon death works as normal.

🏆 Achievement Rewards (Advancements)

• Progression milestones have been updated (10%, 50%, 100% of the level).
• The ‘rewards’ block has been integrated: physical rewards (Dynamic XP Bottle, Shield Core) and bonus experience are now awarded for achieving milestones.

v1.6.1 - UI Overhaul, Sync Triggers & Modern Asset Binding

🎨 Interface and Command Line (Server & Client UI)

• Interactive pagination /lifexp status [page]:
  • Complete refactoring of parameter output: the list of 15 attributes is split into pages of 5–6 items.
  • Interactive clickable page-turning buttons [◀] and [▶] (ClickEvent.RUN_COMMAND).
  • Raw technical identifiers (such as submerged_mining_speed) have been hidden: human-readable, localised names have been implemented.
  • Fine details (50% cap step and scaling type) have been moved to compact tooltips HoverEvent.ShowText.
• Redesign of the /lifexp top leaderboard:
  • Added gradient differentiation for prize positions (Gold for 1st place, Silver for 2nd place, Bronze/Red for 3rd place).
  • Standardised the visual style of frames and separators to match the mod’s colour scheme (GOLD + DARK_GRAY).
• Attribute preview (/lifexp get attr):
  • Converted to a standardised status formatting scheme with tooltips.

⚙️ Synchronisation and Network (Network & State Fixes)

• One-Shot Sync via the ESC key:
  • A client-side interceptor for ClientGuiEvent.SET_SCREEN has been implemented to open the PauseScreen.
  • When the pause menu is called, a point-to-point C2S synchronisation packet is sent: the server performs an immediate recalculation and pushes a ClientboundUpdateAttributesPacket. The issue of heart containers (generic.max_health) getting stuck has been resolved without placing a constant load on the server tick.
• Network Architecture Adaptation:
  • Network packet signatures have been updated to comply with modern CustomPacketPayload standards.

🖼️ Assets and Rendering (Assets & Tree Fixes)

• Achievements tab background fix:
  • Fixed the black-and-purple chequerboard pattern (missing texture) in the root node of the achievements tree (root.json).
  • Correctly linked the background tiling resource (life_xp_challenge:textures/gui/advancements/backgrounds/root_bg.png) with a safe fallback.
• Render buffer safety:
  • Matrix transformations in LifeXpVisualsClient have been isolated in the event of an early exit via isDeadOrDying().

v1.5.4 - Content Update, Frozen the branch and Complitly growth up to 26.2

🔮 Data-Driven Enchantments (Minecraft 1.21.1 JSON Format)

• XP Harvester (life_xp_challenge:xp_harvester):
  • Maximum level: III.
  • Applicable to Pickaxes and Hoes (#minecraft:pickaxes, #minecraft:hoes).
  • Added to the standard enchanting table tag (#minecraft:enchantment/in_enchanting_table).
  • Mechanics:
    • Mature Crops: Harvesting fully-grown crops (CropBlock with isMaxAge) drops 1–2 Experience Orbs.
    • Vanilla Ores: Mining Iron, Copper, Gold, Lapis, Redstone, or Diamond ores yields scaled bonus experience based on enchantment level (level * 2 to level * 5 XP).
    • Ancient Debris: Yields a high-stakes reward equal to 1% of the player's total experience points (capped at a maximum of 500 XP per block).
• Anomaly Angler (life_xp_challenge:anomaly_angler):
  • Maximum level: I.
  • Applicable to Fishing Rods (#minecraft:enchantable/fishing).
  • Added to the standard enchanting table tag (#minecraft:enchantment/in_enchanting_table).
  • Mechanics: Unlocks anomalous treasure drops when fishing.

🎣 Fishing & Loot Overhaul

• Treasure Loot Injection: Hooked into minecraft:gameplay/fishing/treasure via Architectury's LootEvent.MODIFY_LOOT_TABLE.
• Custom Loot Condition: Implemented HasAnomalyAnglerCondition (life_xp_challenge:has_anomaly_angler) checking the tool in hand for the anomaly_angler enchantment.
• Custom Loot Function: Implemented AnomalyFishingLootFunction (life_xp_challenge:anomaly_fishing_loot):
  • Shield Core (shield_core): Added to the anomalous treasure pool.
  • Damaged Life Bottle (life_bottle): Can be caught with pre-inflicted damage (only 1–2 durability points remaining) using vanilla minecraft:damage Data Component.
  • Charged Dynamic XP Bottle (dynamic_xp_bottle): Can be caught pre-filled with 5 to 40 stored experience points using life_xp_challenge:stored_xp Data Component.

⚙️ Modern Data Components (1.21.1)

• Registered custom Data Component life_xp_challenge:stored_xp (DataComponentType<Integer>) via Architectury registry.
• Fully migrated DynamicXpBottleItem from legacy NBT compound tags to modern Minecraft 1.21.1 DataComponents.

📖 JEI / EMI Integration & Localization

• Added dedicated JEI Information tabs (addItemStackInfo) for Enchanted Books containing XP Harvester and Anomaly Angler.
• Complete trilingual translations across all new content:
  • English (en_us)
  • Russian (ru_ru)
  • Turkish (tr_tr)
• Full Turkish parity: localized JEI descriptions, enchantment names, ModMenu metadata, and advancements.

🛠️ Toolchain & Compatibility

• Java Toolchain: Strictly pinned build and runtime toolchain to Java 21 (JavaLanguageVersion.of(21)) in root build.gradle.
• Daemon & Run Tasks: Configured org.gradle.java.home to target JDK 21 explicitly.
• SpongePowered Mixin Compatibility: Resolved runtime crash (Unsupported class file major version 69) when executing :fabric:runClient on machines with Java 25 installed by ensuring Mixin runs strictly within Java 21 bytecode limits.

v1.5.3+1.5.2 (Finished and update to new Minecraft Versions)

[1.5.3] - Final Release for Minecraft 1.21.1 (Legacy)

This is the final stable patch for the 1.21.1 architecture (Java 21). The legacy-1.21.1 branch is now frozen. All future development (starting from v1.6.0) is officially moving to Minecraft 26.1.1 (Java 25).

🐛 Visuals & Bug Fixes

• Fixed dynamic liquid rendering for DynamicXpBottleItem and LifeBottleItem. Added the missing 0xFF000000 opacity mask to prevent ARGB colors from rendering as invisible.
• Fixed client-side visuals overlaying the death screen. Ash particles spawning and the dynamic vignette are now properly blocked by an isDeadOrDying() check.
• Fixed OpenGL graphical artifacts during vignette rendering. The alpha channel calculation is now strictly clamped to the [0.0, 1.0] range using Math.clamp.
• Fixed item JSON models. Removed hardcoded links to vanilla potion textures (minecraft:item/potion); models are now properly bound to the custom life_xp_challenge assets.
• Fixed the missing texture (black and purple squares) for the XP Shield effect icon in the inventory.

[1.5.2] - Visuals & Shaders Overhaul (Fog Replacement)

🎨 Visuals & Immersion (Major Refactor)

• Removed Legacy Fog System:

• Completely removed FogRenderer mixins and dynamic fog density alterations that caused chunk culling bugs, rendering distance truncation, and shader incompatibilities.

• Removed obsolete configuration properties (enableCustomFog, disableFog, fogStartDistance, fogMidDistance, fogEndDistance) from LifeXpConfig, YACL GUI Screen, and commands (/lifexp get fog, /lifexp set fog).

• Dynamic Client Vignette (HUD Overlay):

• Added new client handler LifeXpVisualsClient.

• Listens to Architectury's ClientGuiEvent.RENDER_HUD to blit textures/gui/vignette.png across the screen.

• Full transparency at $\ge 50%$ of maxLevel, darkening screen edges progressively as experience drops.

• Ambient Ash Particles (ParticleTypes.ASH):

• Implemented on ClientTickEvent.CLIENT_POST in LifeXpVisualsClient.

• When local player's experience falls below $10%$ of maxLevel, spawns 1–2 ash particles in a 1.5-block radius with a 30% tick chance to convey imminent peril.

v1.5.0 (The Logic & Performance Overhaul)

This massive update completely rebuilds the core mechanics of the mod, introduces new progression systems, and heavily optimizes server performance for large modpacks.

⚡ Performance & Engine Optimizations

• Clumps-Style XP Optimization: Mobs no longer drop dozens of lag-inducing experience orbs. Drops are now merged into a single, high-value orb. Existing orbs in a 2-block radius will also merge dynamically every 5 ticks to save server TPS.
• $O(1)$ Math Refactor: Completely eliminated while loops for attribute calculations. Leveling up to 50,000+ levels will no longer cause Watchdog tick timeouts or server freezes.
• Critical NBT Save Crash Fixed: Resolved the infamous Unregistered holder: xp_shield crash during world auto-saves by rewriting the registry logic to native Registry.registerForHolder.
• Integer Overflow Fix: Experience pooling now uses long types, fixing bugs where taking damage at high levels could heal the player or duplicate XP.

🛡️ XP-Shield Potion Overhaul

The legacy passive shield system has been completely removed and replaced with a balanced brewing system:

• Shield Core: New crafting ingredient required for brewing (crafted with an Ender Chest, not a bundle).

• Brewing Hierarchy:

• Level I (25% Absorption): Awkward Potion + Shield Core (3:00 base, 8:00 with Redstone).

• Level II (50% Absorption): Level I + Glowstone Dust (1:30).

• Level III (75% Absorption): Level II + Nether Star (1:00).

• Note: Absorption burns experience points (1:1 ratio). Taking fatal damage without enough XP will bypass the shield.

⚙️ Gameplay & Presets

• Origins-Style Preset Screen: First-time joiners will now be greeted with a forced, unclosable GUI to select their gameplay preset.
• Strict Preset Locking: Presets can only be selected once per player (tied to NBT). Attempting to bypass this via the /lifexp preset command or the YACL config screen is now strictly blocked.
• New Modifiers: Added purist (classic hardcore with no streak bonuses) and core_no_streaks presets.
• Kill Streak Fix: The Kill Streak XP multiplier now correctly applies to the merged mob drop before it spawns.

🎨 Visuals & UI

• HUD Progress Bubbles: Replaced the clunky text overlay with 10 graphical experience orbs positioned above the hunger bar (1 orb = 10% of the cap).
• Dynamic XP Number Tint: Vanilla XP levels now change color based on progress: Green (< 50%) → Aquamarine (≥ 50%) → Gold (100% cap).
• Fog Culling Fix: Fixed an issue where the dynamic shader fog would cull chunks at early levels. Minimum distance clamped to 16 blocks.
• Blur Fix: Removed the aggressive vanilla blur shader from the custom preset selection screen for better readability.

🧩 Integrations & Advancements

• Full JEI / EMI Support: Added detailed info tabs for custom items (life_bottle, dynamic_xp_bottle, shield_core) and mapped the entire XP-Shield brewing tree for easy viewing.
• Advancements Cleanup: Removed legacy milestones that caused 11,000+ level spikes when triggered.
• New Challenges: Added dynamic achievements: Life or Death (Survive ≤1 HP with Shield III), Expensive Taste, Miner's Vein, and Master Angler.
• YACL Config Cleanup: Stripped deprecated passive shield fields and added toggles for disableFog, showHudBubbles, and lockPresetAfterSelection.

v1.4.8

🚀 Core & Performance

• Watchdog Crash Fix ($O(1)$ Math): Eliminated heavy while loops in experience calculation. Stat recalculation is now handled in $O(1)$ and cached, preventing server tick freezes when receiving massive level bursts (4000+).
• Integer Overflow Fix: Switched experience pooling logic to long with strict bounding, preventing damage from healing players or generating infinite experience at high levels.
• Chunk Culling Fix (Dynamic Fog): Bounded minimum shader fog distance to 16 blocks to prevent visual chunk culling in early gameplay.

⚔️ Gameplay Mechanics

• XP Shield Potion Overhaul:
  • Removed legacy passive shield system. Damage absorption is now tied to the life_xp_challenge:xp_shield potion effect.
  • Added shield_core crafting material.
  • Added brewing recipes:
    • Level I (Awkward + Shield Core): 25% absorption (3:00 / 8:00 with Redstone).
    • Level II (Glowstone Dust): 50% absorption (1:30).
    • Level III (Nether Star): 75% absorption (1:00).
• Origins-Style Preset Selection: First-time joiners are greeted with a mandatory modal GUI to pick their gameplay preset.
• Preset Locking: Applied persistent lifexp_preset_chosen NBT tag to prevent mid-game preset switching once confirmed.
• Modular Presets: Added purist (classic vanilla hardcore) and core_no_streaks profiles.

🎨 Visuals & UI

• HUD Redesign: Replaced legacy text overlay with 10 graphical experience orbs positioned above the hunger bar.
• Dynamic XP Counter Tint: Vanilla experience level numbers now dynamically shift color: Green (<50%), Aquamarine (≥50%), and Gold (100% cap).
• Hover Tooltips: Added extended Shift-click tooltips for all custom utility items across RU, EN, and TR locales.

🛠 Compatibility & Polish

• JEI & EMI Integration: Added full in-game information tabs explaining custom item functions.
• Recipe Fix: Replaced experimental bundles with vanilla Ender Chests in life_bottle crafting.
• YACL Config Cleanup: Stripped deprecated shield options and added toggles for custom fog, HUD bubbles, and preset locking.

V1.4.1 - fabric + neoforge [1.21.1]

🚀 Key new features

• Architectury Monorepo Migration: The entire codebase has been restructured into an Architectury multi-platform architecture (common, fabric, neoforge), guaranteeing 100% feature and logic parity across both mod loaders on Minecraft 1.21.1.

• Heroic deaths against major endgame bosses (Warden, Wither, Ender Dragon) slash the penalty down to 10% of your configured rate.

• Kill Streak XP: Slaying hostile mobs consecutively grants +1% bonus XP per kill (up to +100%). Dying instantly resets the counter to 0.

• In-Game HUD Overlay: A clean, cross-platform HUD element displaying your real-time level, progress to the next level, total cap, and active Kill Streak multiplier.

• Advancement Tree (Milestones): Added an End-themed progression tree with rewards and announcements for reaching levels 100 ("Live and Learn"), 250 ("Diamond Hardened"), and 500 ("Absolute Power").

• Complete Trilingual Parity: All messages, death penalties, chat announcements, item names, and config descriptions now feature full native translations for English (en_us), Russian (ru_ru), and Turkish (tr_tr).
