Noob question about movement

Naming my thread like that is an easy way to say "hey don't laugh at me, but I can't find the right way to write this code ! " lol

Well, what I want to do is that when I say IE "left" to an object, it moves left by a certain distance.

I already find how to use the llListen function to make my object listen and responding at my orders, but my problem is for the movement it self...

Maybe llApplyImpulse ??? Maybe but I don,t really understand how to use it ... HELP PLZ !!!

Edit : And please if you write a code, comment it because I want to learn it, not just copy/paste ... TY !

llApplyImpulse is only for physical objects.

For non-physical objects, things are easier. Just set a position offset. For example:

vector currentPos = llGetPos(); // Gets the current position of the object
vector offsetPos = <0,2,0>; // Creates an offset vector of 2 meters on the Y axis
vector finalPos = currentPos + offsetPos; // Creates final position
llSetPos(finalPos); // Moves the object to that position

Thanks, but the object is physical, I need to see it moving while it goes to point B.

Blatantely stolen from Driftwood Nomad:

llStopMoveToTarget(); // Stop any current MoveToTargets, just in case
vector currentPos = llGetPos(); // Gets the current position of the object
vector offsetPos = <0,2,0>; // Creates an offset vector of 2 meters on the Y axis
vector finalPos = currentPos + offsetPos; // Creates final position
llMoveToTarget( finalPos, 1.0 ) ; // Moves the object to that position over 1 second

Tha'd work, woul'n it?

A couple of things to keep in mind. Maybe not relevant here, but it should be noted.

1. llMoveToTarget will only move something up to 64m in a single call. If you need to move it a greater distance, then you will need to make more than one call. You might, for example, use llTarget to be notified when you are close to the end of your first move and then call llMoveToTarget again. Put this in a loop.

2. At some point, the whole mass/energy thing will bite you. The short description of this is that there comes a point at which an object is too heavy to move itself. A massive prim won't move at all. A prim on the border will move a little bit and then fall down. Make the prim smaller/thinner or hollow it.

3. small objects using llMoveToTarget won't move if more massive objects are attached to them. A good example of this is an elevator. if you make the floor of the elevator too light, then it won't move when an AV is standing on it.

Yeah it WORKS !!!!

But I have to put a distance of 50 insteed of 2 to really see it moving and it comes right back to its original position ?! That's ok, that's what I want but, why is it doing that ?

I'll put my code here and hope you can explain...

vector offset=<3,1,0.1>;
key pikac="cb61cd8a-d125-d6d7-8381-4ebeaab9618b";

startup()
{
    vector pos=llGetPos();
    llSetStatus (STATUS_PHYSICS, TRUE);
    key id=llGetOwner();
    llSensorRemove();
    llSensorRepeat("",llGetOwner(),AGENT,20,2*PI,.5);
}

default
{
    state_entry()
    {
        startup();
    }
    sensor(integer total_number)
    {
        vector pos=llDetectedPos(0);
        llMoveToTarget(pos+offset*llDetectedRot(0),.3);
        llLookAt(pos*106,.1,100);
        llListen(0,"",llGetOwner(),"");
    }

    listen( integer channel, string name, key id, string message )
    {
        llWhisper(0,"OK,Master!");
        llPlaySound(pikac,1);
        if(message=="pkjump")
        {
        llStopMoveToTarget(); // Stop any current MoveToTargets, just in case
        vector currentPos = llGetPos(); // Gets the current position of the object
        vector offsetPos = <0,0,50>; // Creates an offset vector of 2 meters on the Y axis
        vector finalPos = currentPos + offsetPos; // Creates final position
        llMoveToTarget( finalPos, 2.0 ) ; // Moves the object to that position over 1 second
        }
        if(message=="pkleft")
        {
        llStopMoveToTarget(); // Stop any current MoveToTargets, just in case
        vector currentPos = llGetPos(); // Gets the current position of the object
        vector offsetPos = <50,0,0>; // Creates an offset vector of 2 meters on the Y axis
        vector finalPos = currentPos + offsetPos; // Creates final position
        llMoveToTarget( finalPos, 2.0 ) ; // Moves the object to that position over 1 second
        }
        if(message=="pkright")
        {
        llStopMoveToTarget(); // Stop any current MoveToTargets, just in case
        vector currentPos = llGetPos(); // Gets the current position of the object
        vector offsetPos = <-50,0,0>; // Creates an offset vector of 2 meters on the Y axis
        vector finalPos = currentPos + offsetPos; // Creates final position
        llMoveToTarget( finalPos, 2.0 ) ; // Moves the object to that position over 1 second
        }
    }
}

well um what is the sensor suppose to do?

recognize the owner ... is it necessary ?

Because I want to sell these objects later... So when its rez, it needs to recognize the owner, no ?

umm llGetOwner() returns the key of the avatar who owns the object. I could make the object move as you described with out it. So it seems like frivolous code, unless your planning to make it fallow some one.

Your problem seems to be that, regardless of what move may be commanded and under way, every half-second you again sense where your avatar is, and move the object back to a fixed offset from your avatar.
So of course none of your moves complete. They are countermanded every half second.
I may be wrong, but thats how it looks to me.

oh... That makes sense .... !

Sorry about that ! I'm a beginner.


I want that the objetc follow his owner and then when it enter in a state (when its touched it enter the special state) then it don't follow me and execute my moving orders. It need to come back to his original position but only when its moves are finished.

For the touch event, I want it to scan if theres a specify object around in 20 meters and if yes, it enter the special state. But when I touch the object, it doesn't no nothing. So what I got for now is this...

touch_start(integer total_number)
    {
        llSensor("", NULL_KEY, AGENT, 20, PI); // I want it to scan for specified objects names
    }
    
    sensor(integer total_number)
    {
        if(name=="The object aimed") // I don't know what to put at name's place ? it gives me an error.
        {
            llWhisper(0,"The object aimed detected"); // When my object will say this sentence, I will work on the special state
        }
    }

And THANKS guys that help me a lot ! I surf both wiki page and the forum thread to learn, but it's also harder because I'm french and I'm not FULLY bilingual.... You're nice !
