My First Script: Rocket, Need Help

I Have been playing Second life for 2 days, and have been experimenting with code. I decided to start on a life-size rocket to test my skills.

Here is the script:






launch()
{
llWhisper(0, "Take off in..";
llSleep(0.5);
llWhisper(0, "5";
llSleep(1);
llWhisper(0, "4";
llSleep(1);
llWhisper(0, "3";
llSleep(1);
llWhisper(0, "2";
llSleep(1);
llWhisper(0, "1";
llSleep(1);
llWhisper(0, "Lift off!";

llSetStatus(STATUS_PHYSICS , TRUE);
llSetForce(<0,0,100000000000>, TRUE);
}


default
{
state_entry()
{

llWhisper(0, "Welcome to FireFlash v1.0, type /help for details";
llListen( 0, "", llGetOwner(), "" );
}


listen( integer channel, string name, key id, string message )
{
if ( message == "/help" )
{
llWhisper( 0, "Help: Type '/launch' to launch, '/stop' for emergency shutdown. Align your FireFlash in launch direction before launching, with physics turned off. Have fun!" );
}

if (message == "/launch"
{
launch();
}

if (message == "/reset"
{
llSetStatus(STATUS_PHYSICS, FALSE);


vector eul = <0, 0, 0>;
eul *= DEG_TO_RAD;
rotation quat = llEuler2Rot( eul );
llSetRot( quat );
}


}


}





Everything runs fine, help, reset ect, but there is a problem with the launch. The countdown is fine, the physics is enabled, but the rocket just drops to the ground and tumbles over, as if no force has been acted upon it. I have tried up to 10e20 thrust with no avail. The rocket is almost solid metal, if that effects anything, but it still did not work when it was plastic.

Please help me out. I am really stuck

Your probably getting hit with an invisible secret force called 'Energy' trying to use that much llSetForce, try using llApplyImpulse with a more normal value (30,000 or so should give you some serious lift) instead.

-Adam

float frc = llGetMass() * 30;
vector force = <0,0,0>;
force.z = frc;
llSetForce(force, TRUE);

Unless your rocket is huge, this should do the trick.
If it IS huge, try hollowing out a few parts. Or all of them.

If there comments don't help then its most likely too heavy. Try to hollow out the pieces so its lighter. -- Also put the script in the largest prim. bigger prim = more power.

you mean make the parent prim in the link the big one? Also, I would like to add a door to my rocket, that closes on a text command, is that possible?

Just put the anim on the rocket body so you can ride the outside like Slim Pickens in that classic Peter Sellers movie. Come to think of it, Slim Pickens was one of the few parts in that movie that weren't played by Peter Sellers... "Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb".... Ah the good old days when riding a bomb was easy!

LL gives out a free rocket, you could check their code.
LL's scripted objects are always very well commented and examining them is a great way to teach yourself LSL.

Actually, Sellers was supposed to play that role as well, but was so exhausted from playing multiple roles that he tried to get Kubrick to recast it. When Kubrick refused, Sellers faked a broken leg (cast and all), and Kubrick was forced to cast Slim Pickins in the role. IMO, Pickins did a far better job than Seller's would have.
