The mod has long been discontinued.

Causes a crash when placing down an emotion controller

It never was intended for MP.

So I think it's broken for multiplayer

I've been fiddling with this for a few months now, and I can definitely it's a ton of fun to build ships that can flip'n'burn properly. I especially like that it integrates with existing designs without needing major changes.
Unfortunately, it seems that certain encounters, particularly drones, spawned by MES are unable to locomote when this mod is running. As best I can tell, this has to do with a conflict specific to MES grid behavior; enemies spawned by economy missions, for instance, seem to work fine.

getting reports on my mod using this script that the new tether power poles is causing conflict, and cython’s old energy shield mod

I had a problem with intercepting thrust not working, but the [NO RCS] tag helped. And now it's the perfect mod, thanks!

Still, if one uses this mod on its own, (s)he will not get "really poor and expected performance out of improperly placed thrusters". So it is and will remain a cheat mod.

Boodals:
Check out MA Maneuvering Aerospike Thruster .

Trynnun:
Ignoring off-centre thrust when convenient is cheating.

Yeah that figures. A shame because this is my favourite thruster torque mod.
Does anyone know of any other thruster-torque mod that is lightweight and controls steering? Digi's doesn't do steering, and TP & DT seems too overcomplicated.

The mod doesn't affect NP ships at all. It is also not supported anymore.

How does this mod treat NPC controlled ships? In my playthrough, the hostile drones just sit still in the sky, although the large grid ships seem to move just fine (they just have a linear flight path). I haven't confirmed its because of this mod, but it seems likely.
The description says that thrusters are used for steering and not movement until you assign them to the [NO RCS] group. Wouldn't it have made more sense to do the opposite, made thrusters move but not turn by default. Since vanilla ships will come with gyroscopes so they can overcome some thrust imbalance, but until they are assigned the group they won't be able to move.

OH GOD YEEEAAAAH!! I am infinitely grateful to you! Thx!!))

Ulfsark:
The crash occurs inside Keen's code; there is nothing I can do about it.

EDIT:
After some more testing I've found that crashes no longer occur if I remove "Smart Turrets" mod from the world.

EDIT #2:
I think I've found a workaround that doesn't require removal of "Smart Turrets". If crashes still trigger, let me know.

Even on this mod the game crashes as soon as I turn. here's the world.

Nixeen:
Because issues caused by asymmetric thrust are virtually irrelevant and nonexistent when using this mod.

Why is it now called "cheat mod" ?

KC Pilot:
Both mods actually do this. Make sure that overridden thrusters are in [NO RCS] group to prevent the mod from interfering.

For some reason this mod is desabling thrust over ride. I thought that was only the full blown mod that did that?

Digi:
Silly me.

Doesn't typing Q or E rotate the ship ? xD

Digi:
Thanks for the tip. Checking CameraController directly against Sandbox.Engine.Utils.MySpectatorCameraController seems to work as well.

With regards to chat, it shouldn't pose any trouble with this particular mod, but it's definitely the problem with the other one.

Oh and the chat is also a place where input annoyingly can't be skipped :(

I'd just like to add about the input, your spectator detection won't work properly if you press spectator keys in a state (like in a menu) that won't actually enable spectator.

You're better of just checking if the camera is either a character or a block, anything other than that is probably a spectator (unless I've forgot something xD)
