MSIFvAPI v8 - Create items with skills easily!

💥 MSIFvAPI ULTRA is an advanced Minecraft Bedrock addon framework that lets you give items and armor powerful, customizable skills using a flexible tag system. Designed for addon creators and mapmakers, it enables dynamic gameplay using item switching, offhand interaction, passive skill listeners, and full armor set bonuses.

✅ Core Features (ULTRA Version):

🔁 Multi-Skill Items – Attach multiple skills to one item and switch between them using hold time, buttons, or offhand logic.

🛡️ Armor Piece Skills – Equip helmets, chestplates, leggings, or boots with their own active or passive skills.

🧱 Armor Set Bonuses – Unlock powerful effects when wearing matching armor pieces (1–4 pieces supported).

🖐️ Offhand Skill Use – Activate offhand item skills using dedicated controls (Interact Offhand).

🕹️ JSON UI Buttons – Add responsive on-screen buttons to activate or switch between skills (touch + controller support).

🧪 Passive Event Listeners – React to in-game events like taking damage. Great for reactive armor skills or buffs.

🧠 Command Binding Support – Use tags to bind any function or command to an item (requires Dev Commands Addon).

🔄 Cooldown System – Group skills under shared cooldowns with visible names and time tracking.

🌐 Multiplayer Compatible – All skill tracking is player-specific and tested in multiplayer scenarios.

🪶 Lite Mode Compatible – Seamlessly use Lite and Ultra tag formats together for performance flexibility.

📡 Passive Event Listeners:

Define passive skill triggers using UMSIF: tags. These work without needing item interaction.

• onHurt – Triggers when the player takes damage
• onAttack – Triggers when the player damages an entity
• onKill – Triggers when the player kills an entity
• onJumpPress – Triggers when the player presses the jump button
• onJumpRelease – Triggers when the player releases the jump button
• onSneakPress – Triggers when the player presses the sneak button
• onSneakRelease – Triggers when the player releases the sneak button
• onBlockBreak – Triggers when the player breaks a block
• onBlockPlace – Triggers when the player places a block
• onTick – Triggers every second (20 ticks) while the item is equipped

🏷️ Tag Examples (ULTRA Syntax):

MSIF:function:fireball:skillName:_pcSuper_Fireball:cooldown:fireSkills:dName:_pcFire_Skills:30
→ Skill function with name, cooldown group, and timer (30 subticks = 3s)
