Phantom Vehicle, trying to make it go forward..Even if its been rotated.

I know the scripting for CONTROL_FWD isn't right. I'm just not sure how to go about making it always go forward.


CODE


if(level & CONTROL_FWD)
        {
           llSetPos(llGetPos() + <2, 0, 0>);
        }
if(level & CONTROL_BACK)
        {
                llSetPos(llGetPos() + <-2, 0, 0>);
        }
if(level & (CONTROL_RIGHT|CONTROL_ROT_RIGHT))
        {
           llSetRot(llGetRot()* llEuler2Rot( <0, 0, -10 * DEG_TO_RAD> ));
          
        }
if(level & (CONTROL_LEFT|CONTROL_ROT_LEFT))
        {
           llSetRot(llGetRot()* llEuler2Rot( <0, 0, 10 * DEG_TO_RAD> ));
        }

Slightly offhand but I believe it's.. llSetPos(llGetPos() + ( <2,0,0> * llGetRot() );

Get a syntax error with that.. I think Rot2Fwd needs to be used here... I'm just not sure how.

+ 2 * llRot2Fwd(llGetRot()) I would think... or is there a shortcut?

Yumi's is my preferred method, the syntax error is likely because there is a closed bracket missing from the end

Now I did not know that you could multiply a vector by a rotation to rotate the vector. That's useful information. I've been doing it manually.
