OSSL vs LSL
From OpenSimulator
Revision as of 09:09, 15 June 2023 by JeffKelley (Talk | contribs)
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 out-of-linkset by uuid. | |
| llCreateLink llBreakLink llBreakAllLinks |
osForceCreateLink osForceBreakLink osForceBreakAllLinks |
Does not require PERMISSION_CHANGE_LINKS | |
| llParticleSystem llLinkParticleSystem |
osParticleSystem osLinkParticleSystem |
H L |
|
| llSitTarget llLinkSitTarget |
osSetStandTarget osSetLinkStandTarget |
H L |
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 |
