How do you get started with FTB Ultimine?
5 parts
Same as in the FTB Skies 2 1.22.0 guide
FTB Ultimine lets you break or modify a whole group of blocks in one go. The sources I have for this pack only cover the mod's in-game text, so this section sticks to the controls and settings you will meet first, rather than a crafting order.[1]
Find your Ultimine key
The mod adds its own key binding, listed under the FTB Ultimine category in your controls. The default key is the backtick key. Holding it is how you switch Ultimine on while you mine.[1]
Pick a shape
Ultimine can break blocks in different shapes. With the default keys, the up and down cursor keys cycle through them. You can also hold the Ultimine key and sneak at the same time to open the shape selection menu, which shows the selected shape with some shape names above and below it.[1]
A few client settings change this. One decides whether you must hold the Ultimine key to cycle shapes with the keyboard. If it is off, you can cycle at any time. Another decides whether you must sneak to show the shapes menu. There is also an option to show a hotbar message with the new shape whenever you change it.[1]
Use a proper tool
The server can require that you hold either a damageable tool or an item in the ftbultimine:tools item tag before Ultimine works. A separate option can require the tool to be valid for the block, meaning it can actually harvest the drops. If Ultimine does nothing, check your tool first.[1]
There is also a durability guard: Ultimining stops when your tool has a set amount of durability or less left. Setting that value to 0 lets tools break.[1]
Limits to know about
- A maximum number of blocks can be broken or modified in one operation.[1]
- A cooldown, measured in ticks, applies between uses. 20 ticks is 1 second.[1]
- Each block can cost hunger exhaustion and experience. Both amounts can be fractional.[1]
- If FTB Ranks is installed, its permission nodes for max blocks, cooldown, exhaustion and experience take priority over the mod's own settings.[1]
Farming
There is a server option for single crop harvesting. When it is on, right-clicking a crop without the Ultimine key held harvests it.[1]
Unverified The sources here do not show the pack's actual Ultimine values, such as the block limit, cooldown, costs, or whether a tool is required. Those are set in the mod's server settings, and the sources here do not show them.
