How could I stop a craft rotating through Lua?

I have tried this:

Code:
function Update(self)
   self.AngularVel = 0
   end


It doesn't show any errors but doesn't work for some reason, I bet this is something incredibly simple.


EDIT It's an ACRocket by the way.

Not sure what you're looking for, but you probably want to disable both the MOVE_LEFT and MOVE_RIGHT controller states if you just want to prevent turning.
If you really want to stop rotation, lock the rotation angle as well as velocity.

It is a drop crate class, so I don't need to prevent left and right controls, I need to stop it turning altogether.

As in, make it only go straight down and straight up.



EDIT
How would I lock the rotation angle?

self.RotAngle = <whatever, probably 0>

Also, if I understand you correctly, you might want to lock X vel to 0(self.Vel.X = 0).

Thanks so much, It worked to perfection.

Also, very offtopic and you probably won't know, but how would I make it switch control to the craft?

On creation?
ActivityMan:GetActivity():SwitchToActor(self,<player number>, self.Team)

Thanks, I'll be sure to credit you by the way.

Here is the final script:
Code:
function Create(self) --Don't really need this since I can just edit the ini but anyway.
    self.Vel.X = 0
    self.Vel.Y = 10
end
function Update(self)
if UInputMan:KeyHeld(19) then --If "S" is held, move down at 10 velocity.
   self.Health = 100            --Don't die either.
    self.Vel.X = 0                     --No jiggling for you!
    self.Vel.Y = 10                   --Move
end
if UInputMan:KeyHeld(23) then  --If "W" is held, explode.
   self:GibThis();
end                                      --Ends "then" and "if" so that rotating can be stopped each frame.
   self.RotAngle = 0            --Stops rotating.
   self.Vel.X = 0
   end                              --End mother****er.



I took this from a whole lot of different mods I have made in the past and put it all together.

It's for this.

If you want this to be Gamepad friendly you should do it like this instead.

Code:
function Create(self) --Don't really need this since I can just edit the ini but anyway.
    self.Vel.X = 0
    self.Vel.Y = 10
end
function Update(self)
self.cont = self:GetController(); -- get controller
if self.cont:IsState(Controller.BODY_CROUCH) then --If down is held, move down at 10 velocity.
    self.Health = 100            --Don't die either.
    self.Vel.X = 0                     --No jiggling for you!
    self.Vel.Y = 10                   --Move
end
if self.cont:IsState(Controller.BODY_JUMPSTART) then  --If up is held, explode.
   self:GibThis();
end                                      --Ends "then" and "if" so that rotating can be stopped each frame.
   self.RotAngle = 0            --Stops rotating.
   self.Vel.X = 0
end                              --End mother****er.
