[Opensim-dev] 23 LSL functions remaining

Tue May 12 16:41:53 UTC 2009

Thats easy. Since there is no specification, and all we can do is test scripts of various flavors from "completely non-functional" to "wondrously crafted", we *all* get to decide what a function "should" do.

This is a community effort. As a community, various folks contribute source from time to time. Various other folks are dedicated to testing and reporting the results.

So, "patches" are the key to moving any implementation *or* compatibility forward.

But then surely the question comes down to an understanding of what any particular function 'should' do. Is it entirely up to the writer to decide what any function is, and should do, or is there a clear definition of each function that they should be compatible with?

You cannot have partial compatibility, or no-one would have any confidence. I believe that LSL functions should be 100% compatible (written differently, of course, but the inputs and outputs should always be the same), or another scripting language should have been used (eg Lua) or developed.

I for one see Opensim use my opensim as a development platform, and I have been using it for development before bringing my creations into SL. I have not done much scripting yet, until all the functions are implemented, but I would expect that all the scripts I develop in my Opensim sandbox to work when I import them into SL.

My goal here is to get at least "some" implementation for all the LSL functions.

Given at least "some", then the debate of compatibility starts to get interesting to more folks.

So, getting back to my original point, a few patches to get "some" implementation on the 27 or so (including the new ones and discluding a couple that SecondLife says are unused), lets see if we can get to where we can have some interesting 'compatibility' discussions.

I think it is fair to say that the list, excluding (u), (d), & (g) from http://wiki.secondlife.com/wiki/Category:LSL_Functions represents the list of those functions that should be implemented. Perhaps others could comment on this and help us get closure on this year and a half long project of implementing these functions.

There is also the question of compatibility with LSL. Questions have been raised about whether Opensim can be used as a development tool for SL. Here is one thread that calls compatibility into question:

http://www.sluniverse.com/php/vb/opensim-discussion/26340-opensim-compatibility-place-develop-secondlife.html

Is the aim to have 100% compatibilty, so that scripts developed in Opensim will be guaranteed to work in SL, and vice versa? As the old saying goes, you cannot be a little bit pregnant, it is either 100% or nothing.

I am asking for a few patches to complete the 23 LSL functions in our original project of more then 330. We are *almost* there, but need a little help with patches. Here is the remaining list that are still in the "Not Implemented" state.

llRotTarget()
llRotTargetRemove()
llLoopSoundMaster()
llLoopSoundSlave()
llStopLookAt()
llCollisionFilter()
llAttachToAvatar()
llDetachFromAvatar()
llRotLookAt()
llPointAt()
llStopPointAt()
llGodLikeRezObject()
llPassTouches()
llSetDamage()
llTextBox()
llCollisionSprite()
llPassCollisions()
llGetCenterOfMass()
llSetSoundQueing()
llTriggerSoundLimited()
llGroundRepel()
llSetVehicleFlags()
llRemoveVehicleFlags()
llRemoteDataSetRegion()
llSetInventoryPermMask()

Partial implementations are solicited. The goal here is to get all the LSL functions we have defined in LSL_Api.cs<http://LSL_Api.cs> out of the not implemented state with at least *some* implementation.
