Framsticks

I responded whilst I was at work so here is my full nueron.
I can't see what i am missing (other then making some sort of max thrust
param and make it unchangeable via mutations)

I had to abandon the rotate thrust axis concept, was missing some rx, and
ry's for the joint. Was this what was unavailable?

So instead i used the part locations to determine the axis of thrust. This
is actually cheaper computationally. only one sqrt instead of 2 cos, and 2
sins.

For fun, here is a "lander" with its last thruster thrust messed up. its
kinda fun to watch.

(rrCCXCCXX[*][Thrust,-1:0.5],,rrCCXCCXX[*][Thrust,-1:0.5],,rrCCXCCXX[*][Thru
st,-1:-1])

and here is the nueron defination:

class:
name:Thrust
longname:Thruster(EXTREAMLY EXPERIMETAL!)
prefinputs:1
prefoutput:0
preflocation:2
code:~
function init() {}
function vnormalize(v){
var dist =
Math.sqrt(v.get(0)*v.get(0)+v.get(1)*v.get(1)+v.get(2)*v.get(2));
if (dist <= 0.0) {
Simulator.message("Thrust normlized is 0 or negative: "+dist,2);
return;
}
v.set(0,v.get(0)/dist);
v.set(1,v.get(1)/dist);
v.set(2,v.get(2)/dist);
}
function go()
{
var jointnum=n.j;
var cr=Neuro.creature;
var mj = cr.getMechJoint(jointnum);
var j = cr.getJoint(jointnum);
var mp1 = cr.getMechPart(j.p1);
var mp2 = cr.getMechPart(j.p2);
var tAxis= Vector.new();

//x axis Substraction method
tAxis.add(mp1.x-mp2.x);
tAxis.add(mp1.y-mp2.y);
tAxis.add(mp1.z-mp2.z);
//Simulator.message("["+jointnum+"]Begin vnormalize",0);

//Simulator.message("["+jointnum+"]Pos 2:

//SHould put a cap of 0.1 to 0.2 here
var thrust= (Neuro.weightedInputSum)/10.0;

//consume energy
cr.energy = cr.energy - cr.energy_m*thrust;

//get total mass thrusted
var tmass = mp1.m+mp2.m;
//Simulator.message("["+jointnum+"]Mass:

// convert thrust to velocity
thrust = thrust / tmass;

//apply thrust to part1
mp1.vx = mp1.vx + thrust*tAxis[0];
mp1.vy = mp1.vy + thrust*tAxis[1];
mp1.vz = mp1.vz + thrust*tAxis[2];

//apply thrust to part2
