Drop the following items on the ground:
The Ender Bow recipe will also automatically unlock when you obtain the required materials.
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.

Give:
/function coolfunctions:give/jetpack
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!)
⚠️ Experimental: The Morph System is still experimental and may not work perfectly with every mob (especially big mobs like the Iron Golem).
/function coolfunctions:morph/<MobName>
Replace <MobName> with the name of the mob you want to morph into.
/function coolfunctions:unmorph
Ghost Blocks appear as normal blocks, but you can phase through them.
/function coolfunctions:ghostblocks/<BlockName>
Replace <BlockName> with the block you want to get the Ghost Block spawn egg for.
Just spawn it wherever you want
Remove one Ghost Block (the nearest one):
/function coolfunctions:ghostblocks/remove
Remove all Ghost Blocks in a 10×10×10 area:
/function coolfunctions:ghostblocks/removemr
Remove all Ghost Blocks in the world(*):
/function coolfunctions:ghostblocks/ra
*In all the loaded chunks of the world
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.
/function coolfunctions:clearlag
This removes dropped item entities from the world(*).
*In all the loaded chunks of the world
Give an Ender Bow:
/function coolfunctions:give/enderbow
Give a Creative Jet Pack:
/function coolfunctions:give/jetpack
💡 The give functions have been organized under
coolfunctions:give/to make them easier to find and use.
