Fluxnautics
by lunalyti
Fluxnautics adds a NeoForge physics machine that locks a Sable sublevel to a fixed position and applies thrust to it, needing Mekanism and Sable to run.
What it does
A ship-scale vessel built in Sable can be held in place by a physics staff or steered by an ion thruster array. Thrust comes from ion thrusters, which can be grouped into a multiblock array with a Thruster Array Controller and tiered boosters attached to it. The array can take any shape, from a 2x2x2 block to a 3x3x3 one, and the plume color of each thruster is configurable. Energy use scales with the mass of the connected sublevel, so heavier vessels draw more power.
The mod is a Mekanism crossover addon for Sable. It adds a forcefield bubble emitter, which takes a 3x1x3 structure and projects a shield around the whole vessel once it is powered. The physics machine can also cancel the effects of world gravity on a sublevel and reconcile external impulses against its own control. Its energy cost rises with those impulses, and the impulse multiplier is capped at 1000.0 by default. An end-game tier accepts antimatter and produces a very large impulse, with the output direction set in the config. The machine only operates on Sable sublevels. Hydrogen is accepted as an energy source, which allows thrust beyond the air pressure of a dimension.
Key features
Ion thruster arrays
Ion thrusters form a multiblock array of any shape, controlled from a Thruster Array Controller block.
Thruster boosters
Tiered boosters attach to the array and raise the thrust value, with the cap applied to the whole array.
Forcefield emitter
A 3x1x3 bubble emitter projects a shield around the entire sublevel once it receives power.
Physics staff control
A physics staff locks a sublevel to the machine and cancels world gravity, with variable control over the lock.
Global forcefield block
A server-wide forcefield block setting can override which blocks are allowed or blocked.

What the author says
This mod is still being actively developed, as such many components are still using placeholder assets or don't have their UI and rendering fleshed out fully, and new components are likely to be added. Multiblock thruster array you can build however you want, no silly 2x2x2 or 3x3x3, whatever shape you want. Requires…
