📥 Installation

CoolFunctions is available in two forms:

Format	Where	What you need
Datapack + Resource Pack	Modrinth or the original CurseForge project	Two files: the datapack and the resource pack
Mod	Modrinth or this CurseForge project	One single file — the datapack and the resource pack combined

💡 The mod version has the advantage that you only need to download and install one file, since it combines the datapack and the texture pack in one mod.

🖥️ Singleplayer

Choose one of the following:

• Install the datapack + resource pack, or
• Install just the mod.

🌐 Server

Choose one of the following:

• Datapack on the server only: install the datapack on the server. Players only have to download the resource pack/mod (not the datapack).
• Mod on the server: install the mod on the server. Players only have to download the resource pack/mod.

🏹 Ender Bow

📦 Obtaining

Option 1 - Crafting table:

Option 2 - Drop Crafting:

Drop the following items on the ground:

• 1 Bow
• 4 Ender Pearls

The Ender Bow recipe will also automatically unlock when you obtain the required materials.

🎯 Usage

• Hold right-click, just like a normal bow.
• You'll follow the arrow until it lands.
• While shooting, the Ender Bow temporarily uses your offhand slot. The item you were holding there (e.g. a shield) is stored and given back to you afterwards.

🚀 Jet Packs

The Jet Pack comes in five tiers, each providing increased fuel capacity, speed, and maximum altitude.

Each tier also has its own custom color, making it easy to distinguish between them.

💡 The altitude limit is measured as the height above the ground directly below the player(*). Once the maximum altitude is reached, the Jet Pack will no longer provide upward thrust and you will hover around the max altitude.

*Leaves are not counted as ground.

🔋 The remaining fuel is shown as the durability bar of the Jet Pack, and in the action bar together with the current flight mode.

ℹ️ Fuel durations above are for continuous use. Fuel is consumed depending on the selected flight mode (see below), so higher modes burn fuel faster.

---

Creative Jet Pack

A special Jet Pack intended for creative use.

• ⛽ Fuel: Infinite
• ⚡ Speed: Very high
• 📏 Altitude: Unlimited

Give:

/function coolfunctions:give/jetpack

---

🕹️ Usage

• Equip the Jet Pack in your chestplate slot.
• Hold jump to ascend.
• Sneak to cycle through the flight modes.
• Stop thrusting to descend with Slow Falling.

Tip: if Slow Falling is too slow for you, consider switching to your normal chestplate to descend faster and switch back just before hitting the ground (-> no fall damage, but normal fall speed!)

⚙️ Flight Modes

Sneaking cycles through five flight modes. The current mode is displayed in the fuel action bar.

Mode	Ascend power	Notes
0	Hover	Hold your altitude, lowest fuel consumption
1	25%
2	50%
3	75%
4	100%	Fastest ascent, highest fuel consumption

💡 The higher the mode, the more fuel you burn. Pick a lower mode to make your fuel last longer.

👤 Morph System

⚠️ Experimental: The Morph System is still experimental and may not work perfectly with every mob (especially big mobs like the Iron Golem).

🪄 Morph into a Mob

/function coolfunctions:morph/<MobName>

Replace <MobName> with the name of the mob you want to morph into.

🔙 Unmorph

/function coolfunctions:unmorph

👻 Ghost Blocks

Ghost Blocks appear as normal blocks, but you can phase through them.

📦 Obtaining

/function coolfunctions:ghostblocks/<BlockName>

Replace <BlockName> with the block you want to get the Ghost Block spawn egg for.

🧱 Usage

Just spawn it wherever you want

⚙️ Utility Functions

Cool Functions also provides various utility functions that can be accessed directly through Minecraft's /function command.

ClearLag allows you to manually remove dropped items from the world. This can help performance when there's a lot of items on the ground.
