Ok, So for my Silly Federation I want the Rocket Launcher to be powerful, but go up and down randomly. Not just ---\__Crash but like /\/\/\/\/\/\----Crash So its like Up down curves and random

If anybody at all can refer me to a Wiki For the Lua i'd be grateful. Also if maximdude is on here i ♥♥♥♥ love you man.

Code:
function Create(self)
    function sinewave(amplitude,wavenumber,angvel,phase)
        return amplitude * math.sin(wavenumber - angvel + phase / 30);
    end
   
   function sawtooth(x,range,slope)
      return (x % range) * slope
   end

   self.initialy = self.Pos.Y - 20;
end

function Update(self)
   --self.Pos.Y = self.initialy + sinewave(30,1,math.pi,self.Pos.X);
   self.Pos.Y = self.initialy + sawtooth(self.Pos.X,100,0.5);
end


Code:
function Create(self)
    function sinewave(amplitude,wavenumber,angvel,phase)
        return amplitude * math.sin(wavenumber - angvel + phase / 20);
    end
   self.initialy = self.Pos.Y;
end

function Update(self)
      self.Pos.Y = self.initialy + sinewave(40,1,math.pi / 2,self.Pos.X);
end


Try these out, see what you think.

They're not exactly random, but they do go up and down in a fixed way. Adding an element of random-ness would be fairly easy, as well.

Alright Yeah, that works decently except Its now what i'm looking for. I want it to rotate the missile not move it up and down, so basically the rocket will OrienttoVel and just look good.

How would i do that, Lua Docs don't Seem to help, however i'm new to lua and cant really understand.

Lua Docs are for the functions.
To learn lua itself, the offical lua site has some good tutorials.

EDIT:
Also you need to look at the function dump, and read some code, as the lua docs are half arsed.

Well hey, thanks guys. I've Been Messing with some things and i figure i'll have the thruster rotate on an offset at random. You guys really helped, so thanks.
