Summary

0008868: BulletSim llMoveToTarget is not moving to target.

Description

hi,

i have an elevator system based on physics. it works pretty well with the unmanaged ubode on my arm based tinkerboard but it didn't work at all with bulletsim (not with BulletXNA and not with unmanaged BulletSim).

this little example script should work:

Steps To Reproduce

vector base;
default
{
    at_target(integer n, vector t, vector w) {
        llSetStatus(STATUS_PHYSICS, FALSE);
        llTargetRemove(n);
        llSetPos(base);
    }
    touch_end(integer n) {
        vector target = base + <0,0,10>;
        llSetStatus(STATUS_PHYSICS, TRUE);
        llSetStatus(STATUS_ROTATE_X | STATUS_ROTATE_Y | STATUS_ROTATE_Z, FALSE);
        llMoveToTarget(target, 2*llGetMass());
        llTarget(target, 0.2);
    }
    state_entry()
    {
        llSetStatus(STATUS_PHYSICS, FALSE);
        base = llGetPos();
    }
}

Additional Information

and it works with obode but not with bullet physics. i'm pretty sure it will also work with ode. when i attach the object, it works well. but i don't like to attach an elevator.

Notes
(0037579) djphil (reporter) 2021-02-20 02:56	llMoveToTarget is not fully implemented in BulletSim, only 'semi'. See : http://opensimulator.org/wiki/BulletSim/Functionality [^] PS : Tested and confirmed.

(0037580) tampa (reporter) 2021-02-26 23:00	Not quite sure even why that is, there are some notes on this in Bullet about it not being fully implemented, but no reason is given why or what the problem was preventing implementation. Haven't seen Robert on irc lately, might be best to ask him why that's missing.
