Run commands from custom item data!
Cobalt core is a datapack that allows for items to run commands from custom data!
To Use: Enter the command you want to run into the proper custom data path:
{
"components": {
"custom_data": {
"cobalt": {
"onUse": {
"command": "say Hello World!"
}
}
}
}
}
Below are all current uses for Cobalt Core, along with example commands:
