How would I create an object that could tell me how much an object (or av) weighs? I see there's a GetAgentSize function but no GetAgentWeight one. :/
I'm guessing that since GetMass only returns the mass of the object the script is attached to, the scale would have to first be attached to the av, then the scale's weight removed from the combined weight. Surely it's been done before though...

It's possible I have no idea what I'm talking about here, but this script... default
{
touch_start(integer total_number)
{
key detected = llDetectedKey(0);
if (detected == llGetOwner());
{
float mass = llGetMass();
vector size = llGetAgentSize(detected);
// vector size = llGetScale();
float density = mass / size.x / size.y / size.z;
llSay(0,"Mass: " + (string)mass);
llSay(0,"Size: " + (string)size);
llSay(0,"Density: " + (string)density);
}
}
}
...returns 3.489141 for density on avatars, and 10.0 for density on other objects. (Uncomment the second "vector size" line for objects.) You should be able to figure out a mass estimation based on this, as the bounding box's width and depth are constant. Only height, the Z axis, changes. |

Thanks, but isn't the mass already determined via GetMass? Did you mean determine a weight estimation or...?

Avatar weight is a constant. So, once you figure it for one av, you have them all.  -Adam |

i dont think av weight is a constant, it seems small AV are more affected by physic than big AV

AV mass *NOT* a constant. Put this code in a prim. Attach the prim. Touch it to see your mass. Make yourself taller. Touch again, and you will get a larger number. Also, it looks like llGetMass() in an attachment returns the mass of the AV alone. It doesn't look like it includes the mass of attachments.
default
{
state_entry()
{
llSay(0, "Hello, Avatar!");
}
touch_start(integer total_number)
{
llSay(0, "mass = " + (string) llGetMass());
}
}

I dunno if it always shows up the same via llGetMass but I do know that llPushObject does act differently on smaller avs vs large. not to mention a larger av gets pushed less when firing a heavy projectile. |

attachments have no mass.

From: Rickard Roentgen attachments have no mass. Neat! Just verified this! I just tried this: Put a physical movement script into a prim that was too heavy to move. Unattached, it would try to move and then fall down. Attached, it moved just fine. Just for kicks I tried sitting on it. as expected, it behaved as unattached.

Found this thread via a search; I've been playing around with some physics recently and got interested. It answers my question as to how to find one's own mass.
What I was wondering, though, was what the average mass of an av is? Has anyone got any idea? Perhaps one could do a survey...
