Is there any way to increase a prim's mass without having to add more prims? I find SL's material types to be VERY light. Stone should be MUCH heavier. It would just be better to have a way to specify a prim's mass instead of having to rely on more/hollowed prims, etc.

Easy! Simply change the gravitational constant of the universe!  Er... no, sadly, I don't know of any way to directly change the mass of a prim or object. You could probably use llSetForce() on the object to increase the downward force acting on the object, which would make it weigh more...

You could also scale your prim using llSetScale.

Well, SetForce tends to make the prim/object "bouncier" (not settle into place very well so it vibrates/shakes/jitters around, and even stop at an angle when not fully touching a surface--it's odd). SetScale isn't what I want since that will change the size, right? What I really need is a SetMass function... SetBuoyancy doesn't work in negative amounts either. :/

a negative amount for llSetBouyancy would make it float in the air.

From: Rickard Roentgen a negative amount for llSetBouyancy would make it float in the air. Shouldnt that make it sink? It's 1.0+ that makes it float.  -Adam |

I think I read somewhere (wiki? forum?) that twisting a prim changes its mass sometime.

No, a SetBuoyancy of 1 will make it "float". 0 will make it normal, and anything in between makes it lighter but will still sink. Negative values have no effect, I've found.

Uh...
What you need to do is SetBuoyancy to something like 2. That'll make it "heavier".
*mutters*Negative numbers... Psh.

Uhh... I just tested this. Negative numbers have a profound effect. They work just fine.
Except they do the same thing SetForce does.

Weird! Coulda sworn I tried them before and didn't notice any effect. Maybe I only tried -.1 or something. Cool! Now if only the physics engine could stablize the "heavier" objects faster... :/
Need a way to reset the bouyancy to 0 after a specified amount of time after a collision occurs to reduce the stablization jittering, but then need to set buoyancy back to heavier when collided with again, then back to 0 after collisions have stopped...hmm, sounds complicated. Not sure if it would work either...

From: Issarlk Chatnoir I think I read somewhere (wiki? forum?) that twisting a prim changes its mass sometime. You probably read something i wrote on energy and/or prim torture. As twist does effect an objects mass, not always in predictable ways. At least you don't have to worry about negative mass prims (grumble grumble hollow restrictions grumble grumble). Hollow only *sometimes* effects prim mass. Hollow is ignored if the hollow mass that is to be subtracted out is greater then the normal mass of the prim (and with twisted shapes this is more often then you might think). I would say more on the issue but i need sleep too.

You should add this to the Wiki, Strife. |

It is, it's in one of my comments at the bottom of the page on llSetPrimitiveParams. But i guess i should put it on my prim torture page.
