This page to highlight the difference between OSSL and LSL functions when similar versions exist.

Work in progress, not to be linked now.

H : Target is the script's host (the prim containing the script)
L : Target is prim in the linkset, adressed by link number
K : Target is any prim you own, adressed by key (inside or outside linkset)
A : Target is an avatar

When a function is marked as supporting different adressing modes, these are overloads (a.k.a. 'variants') selected at compile time according to the parameter types.


llGetLinkPrimitiveParams osGetLinkPrimitiveParams L Allows for multiple-link constants LINK_SET, LINK_ALL_CHILDREN. Returns a by-side list of properties.
llSetLinkPrimitiveParams L No need for OSSL version since llSetLinkPrimitiveParams accepts all LINK_* flags
llGetPrimitiveParams
llSetPrimitiveParams
osGetPrimitiveParams
osSetPrimitiveParams
K Acts on out-of-linkset primitive (uuid instead of linknumber)
osSetProjectionParams H L K Same effect can be obtained with llSetLinkPrimitiveParams (linknum, [PRIM_PROJECTOR]) but OSSL version has osSetPrimitiveParams power to work outside linkset.

llSitTarget

Set the position of the feet of the avatar, when ll version set the position of the Agent Target (Developer > Avatar > Display Agent Target)
llPlaySound
llLoopSound
llTriggerSound
...
osPlaySound
osLoopSound
osTriggerSound
...
L All OSSL sound functions takes a linknumber argument.
llLinkPlaySound L Universal link sound function (SOUND_PLAY, SOUND_LOOP, SOUND_TRIGGER, SOUND_SYNC). Equivalent to resp. osPlaySound, osLoopSound, osTriggerSound, osPlaySoundSlave, osLoopSoundSlave.
llGetNumberOfPrims
llGetObjectPrimCount
osGetPrimCount()
osGetPrimCount(uuid)
H K OSSL version does not count sitting avatars and does work on attachments
llAvatarOnSitTarget
llAvatarOnLinkSitTarget
osGetSittingAvatarsCount()
osGetSittingAvatarsCount(uuid)
H K OSSL function returns the total number of avatars sitting on a linkset. LSL functions apply only to avatars on sittarget (return NULL_KEY if sittarget is not set) and cannot operate outside the linkset. A similar result can be obtained with llGetObjectDetails(uuid, [OBJECT_SIT_COUNT]).
llStartAnimation
llStopAnimation
osAvatarPlayAnimation
osAvatarStopAnimation
A Does not require PERMISSION_TRIGGER_ANIMATION
OSSL can animate multiples avatars, when LSL is bound to the avatar having granted the permission.
llAttachToAvatar
llDetachFromAvatar
osForceAttachToAvatar
osForceDetachFromAvatar
A Does not require PERMISSION_ATTACH.
Target avatar is implicit. To attach explicitely to a given avatar, use osForceAttachToOtherAvatarFromInventory on the avatar's key.
