Einführung
Seit OpenSimulator 0.7.2 stehen eine Reihe von Funktionen zum Erstellen und Bearbeiten serverseitiger NPCs (Non Player Characters) zur Verfügung.
NPCs werden über ein Skript gesteuert, das sich in derselben Region befinden muss wie der NPC. Dies könnte in einem Anhang untergebracht sein, der mit dem Avatar verbunden ist.
Serverseitige NPCs können die Region, in der sie geboren wurden, nicht verlassen.
Das serverseitige NPC-Erscheinungsbild wird gespeichert und geladen, indem die Erscheinungsdatenstruktur mit einer Notecard serialisiert wird, die sich im selben Prim wie das Skript befindet. Die erforderlichen Texturen bleiben erhalten, wenn ein OAR gespeichert und geladen wird.
Das aktuelle Erscheinungsdatenformat (wie in Notecards, die durch das Anschein von Speichern erstellt wurden) ist das gleiche, das für das OpenSimulator-Kabelformat verwendet wird, und ist daher nicht für die direkte Bearbeitung gedacht. Mit größter Sorgfalt ist dies möglich. Weitere Informationen finden Sie unter Appearance Formats Es wird jedoch nicht empfohlen, es sei denn, Sie müssen es wirklich tun.
Aktivieren
Um diese Funktionen nutzen zu können, benötigen Sie in der Datei OpenSim.ini die folgende Konfiguration
- Enabled = true, eingestellt im Abschnitt [NPC].
- Aktivieren der Skript-Engine
in config-include/osslEnable.ini
- AllowOSFunctions = true
- Überprüfen Sie den Wert von osslNPC, um die Rechte der meisten NPC-Funktionen festzulegen.
Sie müssen möglicherweise auch die Rechte von osAgentSaveAppearance() prüfen.
Siehe Configuring Simulator Parameters#Getting information about parameters wenn Sie überprüfen müssen, ob diese Parameter richtig eingestellt wurden.
Notes
- When using your avatar to model appearance before saving, you will need to wait a few seconds before invoking any save appearance command. This is because appearance saving currently operates on a timer in order to manage multiple appearance updates from the viewer.
- When using your avatar to model appearance, if you want to reposition attachments on the NPC you will need to
- Reposition them on yourself
- Detach them to inventory
- Reattach them
- Save the appearance
This is because saving appearance data does not trigger saving of current attachment positions.
Sensing
llAgentSensor() can be used to set up a sensor that will detected NPCs instead/of as well as other region entities.
In OpenSimulator 0.7.2, LSL sensors will detect NPCs as ordinary agents.
In OpenSimulator 0.7.3-rc1 onwards, unless otherwise specified, NPCs will only be detected using the OpenSimulator-specific NPC flag, e.g.
//Author: mewtwo0641 list keys = []; key npc; string toucher; key toucherkey; vector toucherPos; integer npc_on = FALSE; default { touch_start(integer x) { toucherkey = llDetectedKey(0); toucherPos = llDetectedPos(0); vector npcPos = llGetPos() + <1,1,1>; if(npc_on == FALSE) { npc = osNpcCreate("Fred", "Flintstone", npcPos, toucherkey); npc_on = TRUE; llSensor("", "", AGENT | NPC, 96.0, PI); //Will always return NPC key regardless of npc create option return; } if(npc_on == TRUE) { osNpcRemove(npc); llResetScript(); } } sensor(integer num) { keys = []; integer i = 0; for(i; i < num; i++) { keys += llDetectedKey(i); } llOwnerSay(llDumpList2String(keys, "\n")); } no_sensor() { keys = []; } }
You can get NPCs to be detected as AGENTs again using the OS_NPC_SENSE_AS_AGENT option below in osNpcCreate().
The justification is that detecting NPCs as AGENTs by default may make some scripts unusable (e.g. radars that know nothing about NPCs). However, conversely other scripts may not behave as expected if NPCs aren't sensed as agents (e.g. doors that open automatically for avatars would not open for NPCs).
llGetDetectedType() will set the NPC flag if an NPC was detected. If the NPC was created with the OS_NPC_SENSE_AS_AGENT option then the AGENT flag will also be set.
Data Formats
For more information about the format used to store appearance information in notecards, see Appearance Formats.
Functions
Create and Remove
osNpcCreate
osNpcCreate(string firstname, string lastname, vector position, string cloneFrom):key
cloneFrom may be:
- Name of the notecard containing a serialized avatar appearance, or
- Asset UUID of the Notecard, or
- UUID of an avatar logged into the same region. However, please note that this appearance will not be persisted unless osNpcSaveAppearance() is called.
If the NPC is successfully created, then its UUID is returned, which is required for all subsequent functions. Example is available at osNpcCreate
(OpenSimulator 0.7.3-rc1 onwards only). This creates an NPC that is 'owned' by the creating script and sensed using the OpenSimulator-only NPC flag for sensors.
osNpcCreate
OpenSimulator 0.7.3-rc1 onwards.
osNpcCreate(string firstname, string lastname, vector position, string cloneFrom, integer options):key
cloneFrom may be:
- Name of the notecard containing a serialized avatar appearance, or
- Asset UUID of the Notecard, or
- UUID of an avatar logged into the same region. However, please note that this appearance will not be persisted unless osNpcSaveAppearance() is called.
integer is a set of flags that may be 0 or one or more of
- OS_NPC_NOT_OWNED - create an unowned NPC.
- OS_NPC_SENSE_AS_AGENT - create an NPC that is sensed as an AGENT with LSL sensors
- OS_NPC_OBJECT_GROUP - create an NPC with the group of the object with the script, if that object owner is member of that group.
If the NPC is successfully created, then its UUID is returned, which is required for all subsequent functions. Example is available at osNpcCreate
osNpcRemove
osNpcRemove(key npc):void
Remove the given avatar from the region. Example at osNpcRemove.
Get and Set
osIsNpc
OpenSimulator 0.7.3-rc1 onwards.
osIsNpc(key npc):integer
Returns TRUE if the given key is an NPC, false otherwise.
osNpcGetRot
Gets the rotation of the avatar. Only the rotation around the Z plane in Euler rotation (horizontal rotation) has any meaning.
osNpcGetRot(key npc):rotation
osNpcSetRot
osNpcSetRot(key npc, rotation rot):void
Set the rotation of the avatar. Only setting the rotation in the Z plane in Euler rotation will have any meaningful effect (turning the avatar to point in one direction or another). Setting X or Y Euler values will result in the avatar rotating in an undefined manner.
osNpcGetPos
osNpcGetPos(key npc):vector
Return the current position of the NPC.
osNpcGetOwner
OpenSimulator 0.7.3-rc1 onwards.
osNpcGetOwner(key npc):key
Return the owner of the given NPC (i.e. the owner of the script that created it). If the NPC is unowned or the input key does not belong to an NPC then returns NULL_KEY.
Movement
osNpcMoveTo
osNpcMoveTo(key npc, vector position):void
An older function that performs an osNpcMoveToTarget() by flying and landing at the target.
osNpcMoveToTarget
osNpcMoveToTarget(key npc, vector target, int options):void
Move the avatar to a given target over time. How the avatar will get there depends on the following options.
- OS_NPC_FLY - Fly the avatar to the given position. The avatar will not land unless the OS_NPC_LAND_AT_TARGET option is also given.
- OS_NPC_NO_FLY - Do not fly to the target. The NPC will attempt to walk to the location. If it's up in the air then the avatar will keep bouncing hopeless until another move target is given or the move is stopped
- OS_NPC_LAND_AT_TARGET - If given and the avatar is flying, then it will land when it reaches the target. If OS_NPC_NO_FLY is given then this option has no effect.
- OS_NPC_RUNNING - if given, NPC avatar moves at running/fast flying speed, otherwise moves at walking/slow flying speed.
OS_NPC_FLY and OS_NPC_NO_FLY are options that cannot be combined - the avatar will end up doing one or the other. If you want the avatar to fly and land at the target, then OS_NPC_LAND_AT_TARGET must be combined with OS_NPC_FLY. For instance,
osNpcMoveToTarget(npc, llGetPos() + <9,9,5>, OS_NPC_FLY|OS_NPC_LAND_AT_TARGET);
osNpcStopMoveToTarget
osNpcStopMoveToTarget(key npc):void
Stop a current move to a target.
Sitting and standing
osNpcSit
OpenSimulator 0.7.3-rc1 onwards.
osNpcSit(key npc, key target, int options):void
Sit an NPC on a prim target.
osNpcStand
OpenSimulator 0.7.3-rc1 onwards.
osNpcStand(key npc):void
Make an npc stand up.
Communication
osNpcSay
osNpcSay(key npc, string message):void osNpcSay(key npc, int channel, string message):void
Get the NPC to say the given message.
If channel is specified then the chat is said on the given channel. The channel parameter is only available in OpenSimulator 0.7.4 development code at this time.
osNpcShout
Only in OpenSimulator 0.7.4 development code at this time.
osNpcShout(key npc, int channel, string message):void
Get the NPC to shout the given message on the given channel.
osNpcWhisper
Only in OpenSimulator 0.7.4 development code at this time.
osNpcWhisper(key npc, int channel, string message):void
Get the NPC to whisper the given message on the given channel.
Animations
osNpcPlayAnimation
OpenSimulator 0.7.3-rc1 onwards.
osNpcPlayAnimation(key npc, string animation):void
Get an NPC to play an animation. The animation can either be a key or the name of an animation in the same inventory as the script.
osNpcStopAnimation
In OpenSimulator 0.7.3-rc1 there is a bug which makes this play the animation instead. This will be corrected for the final release but in the mean time please use osAvatarStopAnimation() instead.
osNpcStopAnimation(key npc, string animation):void
Get an NPC to stop playing an animation. The animation can either be a key or the name of an animation in the same inventory as the script.
Appearance
NPC appearance is manipulated by saving and loading appearance data to notecards from the same inventory as the invoking script.
osOwnerSaveAppearance
osOwnerSaveAppearance(string notecard):key
Save the owner's current appearance to a notecard in the prim's inventory. This includes body part data, clothing items and attachments. If a notecard with the same name already exists then it is replaced. The owner must be present in the region when this function is invoked. The baked textures for the owner (necessary to recreate appearance on the NPC) are saved permanently.
osAgentSaveAppearance
osAgentSaveAppearance(key agentId, string notecard):key
Save an arbitrary avatar's appearance to a notecard in the prim's inventory. This includes body part data, clothing items and attachments. If a notecard with the same name already exists then it is replaced. The avatar must be present in the region when this function is invoked. The baked textures for the avatar (necessary to recreate appearance on the NPC) are saved permanently.
osNpcSaveAppearance
osNpcSaveAppearance(key npc, string notecard):key
Save the NPC's current appearance to a notecard in the prim's inventory. This includes body part data, clothing items and attachments. If a notecard with the same name already exists then it is replaced. The avatar must be present in the region when this function is invoked. The baked textures for the avatar (necessary to recreate appearance) are saved permanently.
osNpcLoadAppearance
osNpcLoadAppearance(key npc, string notecard):void
Load appearance from a notecard. This notecard must contain appearance data created with one of the save appearance functions.
Touch
osNpcTouch
OpenSimulator 0.7.4 development code at this time.
osNpcTouch(key npc, key objectKey, integer linkNum)
Allows the NPC to touch objects.
Examples
NPC Automator
This is a rough example script for most of the current NPC functionality. One of its major current deficiencies is that it doesn't track more than one created avatar at a time. Please feel free to improve it.

Wandering and Puppeteer
Wizardry and Steamworks provides free-to-use NPC extendable set of scripts, published under the GPLv3 license, that implements most of the NPC functions and allows you to conveniently create NPCs. There are several several scripts available at the time of writing:
- Wandering NPCs is a script that just makes a non-interative NPC wander around in a given area.
- NPC Puppeteer is a system that will allow you to playwright NPCs without too much knowledge of either LSL or OSSL.
OSW NPCs Controller
OpenSimWorld provides an NPC controller that supports interactive NPCs. The system allows you to give commands to NPCs through the local chat and to build complex behaviors through easy-to-write notecards. It also allows you to specify a "map" of your region so that the NPCs can walk through it.
