Using this plugin, you can create custom fuels. They all have custom crafting recipes, names and burning time.
Using the command:
/fuel - (fuel.setup, is the permission)
You can create these fuels.
The command is used like so:
/fuel start /fuel set name <name> /fuel set burntime <burntime> /fuel set recipe shape1 <shape> e.g ABA /fuel set recipe shape2 <shape> e.g BAB /fuel set recipe shape3 <shape> e.g BCB /fuel set recipe material <material name> (The material the fuel will be, it must be an item that can be burnt). /fuel set <letter> <material name> e.g /fuel set B DIRT (You must do this for each different letter). /fuel finish (This will finish the creation and save it to the config, where it can be edited, however you must reload for it to take effect).
