C++ Question KILLROT not working

[Castor]

I have been coding a vessel recently, that uses main engine gimballing for attitude control. But every time I use KILLROT, the vessel gets propelled to Nan space. Other nav modes work fine.

The vessel code has global variables. Could this be causing the problem?

I thought killrot needed RCS in order to function properly?

Possibly, possibly not...but it would be a good idea to fix this anyway, since global variables are bad for storing state in the case where you can have more than one of something, like with vessels...

It does.

It does.

Well, you can always "trick" it by creating dummy RCS thrusters (1e-9 thrust, 1e9 Isp for example) that would indirectly command the gimballing system...

yes, but I doubt that the OP has done that. The real question is why this causes infinite thrust or zero mass to propel him into NaN-space

 

[Castor]

I have defined dummy RCS thrusters for pitching and banking.

Something else that I have observed is that engaging and then disengaging another NAV mode makes the KILLROT work. I have no clue as to why this happens.

The spacecraft can gimbal only on these two axes.
Just to make sure, I added dummy RCS for yaw, but that doesn't solve the problem.
