Bulldozer Poseball

Something that's got on my nerves a bit - sitting on a poseball and getting a wrong/mangled pose because the poseball is clashing with my AO, so I have to turn it off. It's only a minor annoyance, but I looked for a way around it anyway. The following simple "bulldozer poseball" will not be affected by most AO's I've tried:

string ani_name = "sleep";   // Put name of animation here
key sitter;

default
{
    state_entry()
    {
        llSetSitText("Animate");
        llSetAlpha(1.0,ALL_SIDES);
        llSitTarget(<0,0,0.1>,llGetRot());
        llSetText(ani_name,<1,1,1>,1.0);
    }

    changed(integer thechange) {
        if (thechange & CHANGED_LINK) {
            key now = llAvatarOnSitTarget();
            if (now != NULL_KEY) {
                llRequestPermissions(llAvatarOnSitTarget(),PERMISSION_TRIGGER_ANIMATION);
                sitter = now;
            } else {
                llStopAnimation(ani_name);  // Remove if this causes error in some SL vers
                llSay(-8888,((string)sitter)+"booton");
                llSetAlpha(1.0,ALL_SIDES);
                llSetText(ani_name,<1,1,1>,1.0);
             }
        }
    }
    
    run_time_permissions(integer perms) {
        if (perms & PERMISSION_TRIGGER_ANIMATION) {
            llSetAlpha(0.0,ALL_SIDES);
            llSetText("",<1,1,1>,1);
            llSay(-8888,((string)sitter)+"bootoff");  // Lockmeister AO disable signal
            llSleep(0.3);  // Wait for AO to detect state and start its animation
            list n = llGetAnimationList(sitter); // Stop all animations on avatar
            integer t;
            for (t=0; t<llGetListLength(n); t++) llStopAnimation(llList2Key(n,t));
            llStartAnimation(ani_name); // Run our own animation
        }
    }
    
} 

'Drat' - I thought this thread was about bulldozers
