[BUG-1059] llCastRay() sees non-physical objects as physical after physics flag is unchecked.

[sl-service-account]

Steps to Reproduce

Create a castray test object, titled "RNP", with RC_REJECT_TYPES,RC_REJECT_NONPHYSICAL.

Create another castray test object, titled "RP", with RC_REJECT_TYPES,RC_REJECT_PHYSICAL.

From the build menu, rez a wood box.

Have both RNP and RP hit it with castray. (Observe RNP does not return a hit and RP does.)

Turn physics ON then OFF for the wood box.

Have both RNP and RP hit it with castray. (Observe RNP returns a hit and RP does not.)

Expected Behavior

Objects that become non-physical should read as non-physical with llCastRay().

Other information

Check to see if this isn't causing problems elsewhere like the physics engine.

Thanks for the report, Lucia. I can reproduce this in Second Life Server 12.11.09.266804. Here are my scripts:

default
{
    state_entry()
    {
        llSetObjectName("RNP");
        llSay(0, "Touch me for castray");
    }

    touch_start(integer n)
    {
        vector pos = llGetPos();
        // fire downward
        list result = llCastRay(pos, <pos.x, pos.y, 0>, 
            [RC_REJECT_TYPES, RC_REJECT_NONPHYSICAL]);
        llSay(0,"llCastRay results: " + llList2CSV(result));    
     }

}

default
{

    state_entry()
    {
        llSetObjectName("RP");
        llSay(0, "Touch me for castray");
    }
    touch_start(integer n)
    {
        vector pos = llGetPos();
        // fire downward
        list result = llCastRay(pos, <pos.x, pos.y, 0>, 
            [RC_REJECT_TYPES, RC_REJECT_PHYSICAL]);
        llSay(0,"llCastRay results: " + llList2CSV(result));    
     }

}

I positioned the llCastRay() scripted objects above the test object, which was resting on the terrain. When either script 'misses' the object, it hits the ground below, which causes the function to report a hit id of NULL_KEY:

[11:50] RNP: Touch me for castray [11:50] RP: Touch me for castray [11:51] Mæstro: object is nonphysical now [11:51] RNP: llCastRay results: 00000000-0000-0000-0000-000000000000, <149.000000, 104.500000, 24.999996>, 1 [11:51] RP: llCastRay results: 699fc4a1-79aa-9046-3d12-20f6b693be35, <147.667358, 104.500000, 26.275579>, 1 [11:51] Mæstro: enabling physics in object...
