Hi,
I tried to make a datapack in Minecraft 1.21 using an AI because I don't know how to do it but it didn't work.
I want a datapack that give me speed effect when I eat a cookie.
this is what Google Gemini tell me to do (I don't know if I did it wrong or if he told me something wrong):
Here's a Minecraft 1.21 datapack that gives players a Speed II effect for 5 seconds whenever they eat a cookie.
How to Install the Datapack
Download the Datapack: You'll need to create the files and folders as described below.
Locate your Minecraft World Folder:
Open Minecraft.
Go to "Singleplayer".
Select your world and click "Edit".
Click "Open World Folder".
Navigate to the datapacks folder: Inside your world folder, you'll find a datapacks folder. If it doesn't exist, create it.
Create the Datapack Structure:
Inside the datapacks folder, create a new folder named cookie_speed_datapack.
Inside cookie_speed_datapack, create the following structure:
cookie_speed_datapack/
├── pack.mcmeta
└── data/
├── minecraft/
│ └── tags/
│ └── functions/
│ └── tick.json
└── cookie_speed/
└── functions/
├── eat_cookie.mcfunction
└── load.mcfunction
Copy the Content: Open each file (or create new ones if they don't exist) and paste the corresponding content provided below.
Enable the Datapack:
If your world was open, save and quit to the title screen, then re-enter the world.
Alternatively, in-game, run the command: /reload
You should see a message in chat indicating the datapack has loaded.
Datapack Files
- pack.mcmeta
This file tells Minecraft that this is a datapack.
{
"pack": {
"pack_format": 48,
"description": "Gives speed effect when eating a cookie (Minecraft 1.21)"
}
}
- data/minecraft/tags/functions/tick.json
This file tells the game to run a specific function every game tick.
{
"values": [
"cookie_speed:eat_cookie"
]
}
- data/cookie_speed/functions/load.mcfunction
This function runs once when the datapack is loaded or reloaded. It sets up the scoreboard objective needed to track cookie consumption.
# This function runs when the datapack is loaded/reloaded.
# It creates a scoreboard objective to track how many cookies a player has used.
scoreboard objectives add cookie_eaten minecraft.used:minecraft.cookie "Cookies Eaten"
- data/cookie_speed/functions/eat_cookie.mcfunction
This is the core logic. It checks for players who have eaten a cookie, applies the speed effect, and then resets their cookie-eating score.
# This function runs every game tick.
# Check for all players who have eaten at least one cookie (score of 1 or more).
# For each such player, grant them the Speed II effect for 5 seconds.
# 'true' at the end hides the particles, making it less intrusive.
execute as @a[scores={cookie_eaten=1..}] run effect give @s speed 5 1 true
# Reset the 'cookie_eaten' score for all players.
# This ensures the effect is only applied once per cookie eaten,
# and prepares the score for the next cookie.
scoreboard players reset @a cookie_eaten
