Phys objects get flung away

I've been building a lot of little scripted robots lately, and there's something I noticed- any time I rez one of these items with the Physical check box enabled (they have to be physical for a lot of the scripts to work), the object takes off across the sim at blinding speeds, and will keep going until it hits a no entry parcel. In one particular case, I have a little object that follows avatars. When I place it, it goes flying across the room in an arc, like someone threw it, until the llSensorRepeat kicks in and it snaps to the nearest avatar.

However, if I rez the object without physical and let the script turn it physical after a pause, there's no problem.

Anyone experience anything like this?

not usually, unless it's intersecting another prim (or sometimes within the hollow of one)

Do you use llMoveToTarget in your script?

I think the target is a prim property, like color or floaty text. If you Take it while it wants to be going somewhere, it will remember that when you re-rez it..

Even using llResetScript on rez?

Dunno - I'd have to test that..

Are you using llMoveToTarget? If not, it's sorta moot..

On one of the objects, yes.

You could always put llStopMoveToTarget() in the default state_entry and see if that helps. Or I'll test it out later when more time presents itself..

Hm.. It seems that the target does indeed survive a cycle through inventory but not a script reset.. This is the script I tested with and the object starts flying away as soon as it's rezzed then goes tumbling as the reset hits.

default
{
    state_entry()
    {
        llOwnerSay ("state_entry");
    }
    
    on_rez(integer param)
    {
        llOwnerSay ("on_rez");
        llResetScript();
    }

    touch_start(integer count)
    {
        if (llDetectedKey(0) == llGetOwner())
        {
            llSetStatus (STATUS_PHYSICS, TRUE);
            llMoveToTarget (llGetPos() + < 0.0, 0.0, 5.0 >, 2.0);
        }
    }
}

Then try putting llMoveToTarget(llGetPos()+ < 0,0,0.1>, 2.0); in your on_rez event, just before you llResetScript(). If it's still holding onto the old target, maybe setting a new dummy target will divert its attention and make it stay put when it rezzes.

That's work.. Or turning off physics and llStopMoveToTarget.

/me considers adding a JIRA saying that the target should not persist across a trip through inventory. Or can somebody think of a real use case where it's a good idea?

sort of... if the object is designed to occupy a certain position on the sim, regardless of what sim it's rezzed in (networked sensors for example)

perhaps a check before any move to target calls are made, with a variable set in the on_rez event?

Hm.. Maybe.. Still seems to me like it probably causes more trouble than it's worth..

Well, it's annoying as hell, trying to rez something and watching it shoot off the sim.

You guys think I'll have to add a state to it to make it stop moving places on rez, before the rest of the Movement script kicks in?

what about just setting the current target in the on_rez to something like llGetPos?

Or, as I suggested, deliberately moving it to a fresh target a short distance away during on_rez and then doing a llResetScript.

Dunno if it needs a new state but if you don't want it to go flying away, you either need to disable physics on it & llStopMoveToTarget or pick a new, valid target for it or have it move just a little from it's current location. I don't think you have any other options, except for letting it work as it does now...
