 Description  « Hide
It's commonly known that the vast majority of sim crashing weapons are physics based. Making lots of physical objects to overload the server. Likewise, many weapons.

It's really annoying to see places forced to disable building completely, to protect themselves from such attacks.

What I'm proposing is a new parcel flag to disable physical objects. This would work thusly.. (for people who do not have permission)

1. Attempting to rez a physical object should fail. The object would rez as non-physical
2. Attempting to turn an object physical, whether by script, or by build tools, would fail and return an error.

Feedback welcome in comments. This is a kind of half formed idea, so input on it would be appreciated.

I would go with the ability to rez, but not go physical. This behaviour would be similar to the effect of rezzing a physical object in a manner where it is inter-penetrated by a non-physical object and remains non-physical itself. This would also allow for creators to use alternate methods such as non-physical movement for legitimate devices, but still protect the sim from physical object attacks.

How about an auto-return for rezing physical objects? Any physical object rezed immediately gets returned to the owner, that way you don't have any non-physical clutter to deal with, and the griefer is stuck with a massively ballooning inventory. I dunno how hard it'd be to implement that kind of detection, though. Just a thought.

This suggestion might well be obviated by the pending introduction of Havoc 4, which will most likely render physics-based server overload attacks impossible.

Kalel. That's just silly. Havok 4 is better certainly, but that essentially means it just takes more to overload it. It's still quite easy to bring a sim to a grinding halt in havok 4, even if you don't crash it completely. And in some cases, slowing it down massively can be worse.

McCabe, that'd have the additional benefit of triggering the grey goo fence. Currently, if a lot of your objects are being returned you are prevented from rezzing more for a time. I think. I think I accidentally triggered this once entering the wrong radius into a build script that sent pieces flying off the edge of the sim

WarKirby Magojiro added a comment - 19/Nov/07 07:45 AM
Mass rezzing triggers the grey goo fence in any case. Does returning trigger it faster?

Oh, also. Physical objects count double against the grey goo count, I believe. That should be preserved, even when the object is rezzed as non phys, for attempting to rez physical.

Disabling physical objects and push in a parcel would render the people in it safe from most types of attack. Wouldn't do anything about spam, but there are other issues for that.

I dont think this issue is current anymore with Havok4 crashing a region with physics is a lot harder. It's the LSL hacks that are crashing regions now.

I'm going to close this issue because it's no longer ralative. Hope I dont effend anyone.

Darling.

Havok4 fixed this.


WarKirby Magojiro added a comment - 30/Apr/08 03:11 AM
Havok 4 did not fix this. There's more reasons than preventing physics sim crashes. Someone miight want to stop someone from driving a car through their busy club, or firing annoying push bullets.

However, and quite importantly, even with havok 4, you can still lag the sim to death with enough physical objects, which can be arguably worse than crashing it.

Reopening.
