LlGetUsedMemory

2012-09-20T19:58:58Z

Spoof Kelberry: llSetMemoryLimit wasn't added.

{{LSL_Function
|func_id=???|func_sleep=0.0|func_energy=10.0
|func=llGetUsedMemory
|return_type=integer
|func_desc
|Return_text=of the number of bytes of memory currently in use by the script.
|func_footer
|spec=
This function's behavior is dependent upon the VM the script is using. [[#Mono|Mono]] is the new VM, [[#LSO|LSO]] is the old VM. The big difference between between Mono and LSO is that Mono scripts run faster and can utilize four times more memory.

===Mono===

In Mono the value returned is the amount of memory currently in use by the script.

===LSO===

LSO scripts always use 16KiB of memory.

|caveats=
*Scripts compiled to LSO always report 16KB memory used.
*This can be called at any time and does '''not''' require [[llScriptProfiler]]
|constants
|examples=
Calling llGetUsedMemory can look like this:
<lsl>
integer used_memory = llGetUsedMemory();
llOwnerSay((string)used_memory + " bytes of memory currently used.");

=== Cool VL Viewer ===

''' Description '''

This viewer was created and is maintained by {{User|Henri Beauchamp}} (This viewer was formerly known as the "Cool SL Viewer" and its first public release was v1.18.4.3, released on 2007-11-16). It combines elements of several of the other viewers, as well as extra features, bug fixes and extra patches, all very carefully tested.

It puts emphasis on high UI coherency from one version to the other (meaning no bad surprise for "old timers") while staying in sync with Linden Lab's official viewer features, high stability and reliability, and a high reactivity to new patches and bug fixes provided by the Open Source community.

'''The Cool VL Viewer is TPV policy compliant.''' Please see [http://sldev.free.fr/CoolVLViewerReadme.html its TPV TOS].

''' Extra Features '''

* Reverses many of the unpopular interface changes, restoring separate friends and groups floaters and reinstating the packet loss and bandwidth indicators, the old toolbar and buttons layouts, the old/normal commands layout in the pie menus, the "All(old)" search tab, the old style (name-sortable) "Groups" search tab, the "Fly" button in the movement controls floater, and '''optionally''' reinstating the old, more visible, status bar icons and/or tracking dots in the mini-map, and the old chat history floater (without chat input line). Also fixes some UI regressions (missing buttons in some floaters, or visited landmarks tracking in inventory for example).
* Implements the "RestrainedLove" API (formerly known as "RestrainedLife"), based on Marine Kelley's reference patch (switchable and disabled by default).
* Allows to configure the date and time formats to match your locale or personal preferences (including with optional seconds for chat and IM timestamps).
* Allows to wear/remove attachments and clothing items on double-click in inventory.
* Allows to optionally prevent notifications to show and be logged in the main chat.
* Allows to disable typing sounds.
* MUD/MUSH/MUCK/MUX style "poses" (i.e. you can type ":" instead of "/me " to emote), and OOC double parenthesis auto-close (i.e. you can type: "((phone, BRB" and it will show as "((phone, BRB))").
* Allows to hide the "Master volume" when not needed in the panel overlay.
* Allows to build large prims (up to 256m in any or all dimensions) on OpenSim (not on SL, because of server-side limitations).
* Improved friends list floater (with info about what your friends allow you to see: tehri online status and/or their position on the map).
* Improved build tools floater (smaller increments in several parameters, extra "slice" parameter for some prims, transparency up to 100%, check box toggle for drag distance limit, adjustable number of decimals in Object tab for the position/size/rotation parameters, "Align" tool). Also allows to set the "invisible" texture from the texture picker (for invisi-prims).
* Improved texture preview floater (with aspect ratio combo).
* Improved notecard floater (with Edit menu and Search/replace feature).
* Improved mini-map with panning, larger zooming range, specific symbol for avatars above 1024m (work around for a limitation of current server and viewer versions), etc...
* Improved beacons: can filter beacons based on owner (you, others or anyone), can highlight attachments, can dissociate non-object sound sources, can keep beacons "always on" even when the beacons floater is closed.
* Allows to export and import objects you own and created as XML files (for backup and restore purpose, or to transfer objects from one grid to another).
* Allows to connect to all existing grids (and not only LL's) from the login screen.
* Allows network bandwidth up to 10000Kbps.
* Allows to save/compile scripts present in the inventory as Mono scripts.
* Allows to teleport to double-clicked locations on screen.
* Allows to sit anywhere "on the ground".
* Allows to adjust the Z offset (height above the floor) for playing animations.
* Allows to cache the inventory in the background after login (for faster inventory operations).
* Allows to preview animations on your avatar prior to uploading them.
* Implements a group titles floater.
* Implements a radar floater.
* Implements a teleports history floater.
* Implements a "Worn" tab in the inventory floater, and a search/filter by item name, description or creator.
* Implements "speed rezzing" on login and TPs.
* Implements an object "area search" floater.
* Implements the newest LSL functions, highlighting them properly (with tooltips) in the script editor and allowing to compile them. Also implements fully llTextBox() and the AGENT_AUTOPILOT flag with llGetAgentInfo().
* Allows to ignore (and not only decline) friendship and calling card offers.
* Allows to change how minimized floaters are stacked (top/bottom, bottom/top, left/right, right/left, fraction of the screen width to use for the stack).
* Shows avatar keys in profile (in "My notes" tab).
* Shows the avatar true height in the appearance floater.
* Renders properly objects worn on the illegal attachment points defined in some hacked third parties viewers.
* '''NEW: Provides Mesh rendering support ! (v1.26.2 branch only). NEW: Mesh upload support (Linux release only for now).'''
* '''Provides full support for the new Alpha and Tattoo wearables !'''
* '''Provides inventory item links support !'''
* '''Provides multiple attachments per point support !'''
* '''Provides display names support !'''
* Provides Avatar Physics support.
* Provides the new SL web search engine as an option.
* Provides access to web profiles.
* Provides support for setting the new parcel flags (avatar visibility, sounds playing restrictions).
* Allows to filter (Allow/Deny/BlackList/Whitelist) media and audio streams URLs to protect your privacy against IP snatchers.
* Many bugfixes by Henri Beauchamp, Nicholaz Beresford, Gigs Taggart, McCabe Maxsted and others.
* More minor features and improvements, to be discovered on the [http://sldev.free.fr/ website]...
* All switchable extra features easily configurable via a "Cool features" tab in the preferences floater.

=== Meerkat ===

''' Goals '''

* To create a fully GPL viewer (no proprietary dependencies)
* To encourage a community of developers that will submit patches for prompt integration

=== Rainbow Viewer / Cool Viewer ===

''' Description '''

Based on the offical SecondLife sourcecode licensed under GPL2, this speedy Metaverse Client can connect you to a huge variety of exciting Virtual Worlds! It incorporates a lot of improved, new, up- and backported features and fixes that make the fast and rock stable RV/CV the client of choice for many users.

This viewer includes many patches and changes from a lot of different people and sources which I am very grateful to be able to use. Credits are given to everyone I know, in case I missed someone I sincerely apologize.

'''Rainbow / Cool are TPV compliant.'''

Thanks to Henri Beauchamp who laid the foundation for this viewer with his Cool SL Viewer. Special thanks to Winter Ventura for the Cool Viewer logo and Jacek Antonelli and Peter Stindberg for the Rainbow Viewer logo :). And to all the others who helped and supported me, especially the people involved and behind Imprudence!

''' Some incomprehensive list of features '''

A major improvement is an up-to-date OpenGL implementation that especially helps users plagued by ATI's Catalyst drivers but also leads to measurable improvements of overall graphics performance by 30...100% compared to the official viewer; depending on your system. Rainbow Viewer features the current user interface whereas Cool Viewer spots the leaner cleaner and more configurable legacy UI. It's all about choice :).

* New 1.22.12.0 code baseline
* CV's legacy User interface with a clean, simple and userfriendly layout or Rainbow Viewers current official UI, you choose!
* Improved Graphics rendering, especially for ATI users (measured > 1/3 faster than the official viewer)
* Alpha and Tattoo Layer support from Second Life Viewer 2.x
* Updated tested list of Virtual World grids
* Marine Kelley's RestrainedLove (off per default)
* Full Adult Compliance
* Redesigned and "up-ported" search functionality, probably the best search in any viewer nowadays
* Enhanced Breast Physics
* Temporary texture and animation upload
* Better inventory search for content, description and creator
* Low lag radar and AV management tools
* Viewer skinning
* Object and Shape export/import, limited to creator
* Bulk permission editing
* Last owner display to track content theft
* "Worn" tab in inventory
* Double click to wear attachments
* Enhanced building tools
* Flexible Sculpties
* Large Prims (currently only for Opensim grids due to SL limitations)
* Maximized Network Bandwidth
* Flexible Grid selection at login for SL and all OpenSims
* Teleport History and speedy doubleclick teleport
* Avatar UUID in profiles
* Features tab in Preferences for easy switching of features
* Optimized latest OpenJPEG 1.3
* A large number of other goodies and stability fixes that improve your overall experience. Please check the [http://code.google.com/p/coolviewer/wiki/ReleaseNotes Release Notes] for details.

=== Whisper (SlXSLChat) ===

''' A light-weight yet feature rich text-only Second Life client '''

''' Description '''
Whisper is a text-only Second Life client that comes in two parts. The client is written in Java (so it can run on many platforms). The client connects to a "transport", which is written in C# and uses LibOpenMetaVerse. The idea behind this architecture is that if you don't like the client, you can write your own and not have to worry about implementing the Second Life protocol yourself. The entire project is open source and published under the GPLv3 licence.

''' Features '''
* Public chat
* Instant messaging
* Group chat
* Search/join/leave groups
* Search for avatars
* Image retrieval
* Profile retrieval
* Notifications / popups as you would get in Second Life (e.g. group notices, balance changes, inventory offers)
* Teleportation (home, to area within current sim, to nearby avatar)
* Nearby avatar tracking on map of Sim
* Autopilot navigation to nearby avatars
* URL highlighting
* Encrypted traffic between client and transport
* Transport can be run anywhere, the client connects via TCP/IP
* Client only sends MD5 hashed password to transport
* On April 20, 2010, SlXSLChat has rebranded to “Whisper”.

Category:LSL Alpha

2011-11-18T19:28:22Z

Spoof Kelberry: /* Examples */

{{LSL Header|ml=*}}
The term "Alpha" refers to how translucent an object (or, in this case, a prim) is. In Second Life, the alpha property is set by the scripting functions [[llSetAlpha]], [[llSetLinkAlpha]], [[llSetPrimitiveParams]], and [[llSetLinkPrimitiveParams]]. These functions use a [[float]] value. When set to '''0.0''', the object/prim is fully invisible. When set to '''1.0''', the object is opaque.
Sometimes, [[Resident]]s refer to a transparent [[texture]] as ''alpha texture''. This is a texture with an alpha map, not to be confused with this prim property. See [[llSetTexture]] and [[TEXTURE_TRANSPARENT]] instead.

==Build Mode==
In Build Mode, the alpha is represented by a percentage, ranging from '''0%''' to '''90%''' ('''Note''': The '''90%''' cap is for viewers that have been officially released by Linden Lab). Take extra care when moving viewer transparency settings to scripts and back. In the editor a higher number is more transparent, while in scripts a higher number is more visible.

==Examples==
Below are examples on how one may set the alpha of an object.
{|cellspacing="0" cellpadding="6" border="1" style="border: 1px solid #aaaaaa; margin: 1em 1em 1em 0pt; background-color: #F8F8FF; border-collapse: collapse"
!style="background-color: #D2D3FF" | Function
!style="background-color: #D2D3FF" | LSL Example & Description
|-
| [[llSetAlpha]]
| <lsl>llSetAlpha(1.0, ALL_SIDES);</lsl> This will set the object's sides' alpha to opaque, or '''0%'''.
|-
| [[llSetLinkAlpha]]
| <lsl>llSetLinkAlpha(LINK_SET, 0.0, ALL_SIDES);</lsl>
This will set link-set's alpha to transparent, or '''100%'''. ('''Note''': The Viewers released by Linden Labs are unable to set the alpha of an object to fully transparent without a script; the limit is caped at '''90%''')
|-
| [[llSetPrimitiveParams]]
| <lsl>llSetPrimitiveParams([PRIM_COLOR, ALL_SIDES, llGetColor(ALL_SIDES), 0.5]);
// Using llGetColor this way may not give the desired result (it returns the average color)</lsl>
This will set the object's alpha to translucent, or '''50%'''.
|-
| [[llSetLinkPrimitiveParams]]
| <lsl>llSetLinkPrimitiveParams(LINK_SET, [PRIM_COLOR, ALL_SIDES, llGetColor(ALL_SIDES), 0.5]);
// Using llGetColor this way may not give the desired result (it returns the average color).</lsl>
This will set the link-set's alpha to translucent, or '''50%'''.
|-
| [[llSetLinkPrimitiveParamsFast]]
| <lsl>llSetLinkPrimitiveParamsFast(LINK_SET, [PRIM_COLOR, ALL_SIDES, llGetColor(ALL_SIDES), 0.5]);
// Using llGetColor this way may not give the desired result (it returns the average color).</lsl>
This will set the link-set's alpha to translucent, or '''50%'''.

LSL Script Efficiency

2010-11-21T18:43:31Z

Spoof Kelberry: Added llSetLinkPrimitiveParamsFast to this instead list

{{LSL Header|ml=*}}
<div style="float:right;">__TOC__</div>

<div id="box">
== What is Efficiency ==
<div style="padding: 0.5em;">

Efficiency is how much resource a particular script uses to accomplish a goal. This often goes hand-in-hand with speed of execution, but not always.

Things to watch out for, in rough order of importance:

* Using a lot of scripts to accomplish something. See Efficient Design.
* [[llSleep]] - This function uses up 0.2 to 0.3 ms per frame while the script sleeps, timers are much better. ''This is really an accounting error that should be fixed in SL Server 1.27 (see [[User:Andrew Linden/Office_Hours/2009 05 07|transcript]] at 17:44)''
* Short frequency timers (<5 sec)
* Listen - especially to the 0 channel
* Changing textures often (Others have to download them)
* Inappropriate use of server/physical rotations instead of omega
* Event handlers which are not needed (touch, collision, ...)
* Large amount of email or IM
* Inefficient algorithms (like linear search)
* Busy ([[HTTP_Polling|polling]]) loops

</div></div>
<div id="box">

== Efficient Design ==
<div style="padding: 0.5em;">

Each idle script in an object adds 0.001 to 0.003 milliseconds per frame of script time usage. Fewer scripts is better.

* If you need to have a bunch of "buttons", don't put a script in each prim. Use [[llDetectedLinkNumber]] to detect which button was touched from your main script instead.
* If you need to change color, alpha, or texture of child prims, do not put a script in each prim. Instead use [[llSetLinkAlpha]], [[llSetLinkColor]], [[llSetLinkTexture]], [[llSetLinkPrimitiveParams]] or [[llSetLinkPrimitiveParamsFast]].
* '''Never''' put a script in each prim (of a large linkset) that listens on channel 0 (or any other channel). This is probably the worst thing you can do for efficiency. Unfortunately it is all too common.
* Consider using [[XyzzyText]] instead of [[XyText]].

The bottom line is, if you find yourself tempted to put a script in each prim, stop and think about how you could do it differently with fewer scripts. There is almost always an alternative. It is up to you to decide whether the alternative is a viable one for your application.

</div></div>
<div id="box">

== Micro-optimization ==

There are many ways to speed up scripts, such as using ++a instead of a++, however, most of these micro optimizations might not hold true in the future.

== How Fast Does That Code Run ==
<div style="padding: 0.5em;">

The following code will get the time for each function call in millis.

Please first propose changes to the [[Talk:LSL_Script_Efficiency|discussion]] tab. Please do not change the code here without discussion, as any small change could reduce the accuracy of measurements. Please note this code and its comments should exactly match the code and comments presented by the [[Efficiency Tester]] page.

Thanks to {{User|Xaviar Czervik}} for the original code, thanks to {{User|Strife Onizuka}} for tuning the code to produce more accurate measurements, and thanks to the other contributors listed in the history of this article.

== Efficiency ==
<div style="padding: 0.5em;">

The following data was collected using the above function in a recently deployed empty (though not private) sim, with only that one script running in a HUD attachment. 20 tests of each were run and averaged.
++a: 0.173780 ms std. dev.: 0.003393 ms
a += 1: 0.181720 ms std. dev.: 0.013267 ms
a++: 0.243500 ms std. dev.: 0.013816 ms
Thus a++ takes 40% longer to execute than ++a (rough estimate).

While the following data is correct, the function above was not used. A slightly less optimized version written by {{User|Xaviar Czervik}} was used. If someone could please repeat the tests with the function above.

++a: 0.364700 millis
a += 1: 0.346900 millis
a++: 0.413700 millis

Be extremely frugal with LIGHTS! The Second Life viewer is limited to rendering no more than 6 at one time, and each contributes to rendering lag. (OpenGL limitations allow for 8 light sources, SL appears to reserve one each for the Sun and Moon.)

If you need to simulate the effect of several light sources, consider using [[PRIM_GLOW]] and [[PRIM_FULLBRIGHT]] instead.

Category:LSL Alpha

2010-07-25T23:31:49Z

Spoof Kelberry: Added examples pertaining to setting Alpha, as well as descriptions on how it relates to the build tool.

{{LSL Header|ml=*}}
The term "Alpha" refers to how opaque or transparent an object (or, in this case, a prim) is. In Second Life, the alpha property is set by the scripting functions [[llSetAlpha]], [[llSetLinkAlpha]], [[llSetPrimitiveParams]], and [[llSetLinkPrimitiveParams]]. These functions use a [[float]] value. When set to '''0.0''', the object/prim is fully invisible. When set to '''1.0''', the object is non-transparent.
Sometimes, [[Resident]]s refer to a transparent [[texture]] as ''alpha texture''. This is not to be confused with this prim property. See [[llSetTexture]] and [[TEXTURE_TRANSPARENT]] instead.

==Build Mode==
In Build Mode, the alpha is represented by a percentage, ranging from '''0%''' to '''90%'''.
('''Note''': The '''90%''' cap is for viewers that have been officially released by Linden Labs)
==Examples==
Below are examples on how one may set the alpha of an object.
{|cellspacing="0" cellpadding="6" border="1" style="border: 1px solid #aaaaaa; margin: 1em 1em 1em 0pt; background-color: #F8F8FF; border-collapse: collapse"
!style="background-color: #D2D3FF" | Function
!style="background-color: #D2D3FF" | LSL Example
!style="background-color: #D2D3FF" | Description
|-
| [[llSetAlpha]]
| <lsl>llSetAlpha(1.0, ALL_SIDES);</lsl>
| This will set the object's sides' alpha to non-transparent ; '''0%''' using the build tool.
|-
| [[llSetLinkAlpha]]
| <lsl>llSetLinkAlpha(LINK_SET, 0.0, ALL_SIDES);</lsl>
| This will set link-set's alpha to fully transparent, or '''100%''' using the build tool. ('''Note''': The Viewers released by Linden Labs are unable to set the alpha of an object to fully transparent without a script; the limit is caped at '''90%''')
|-
| [[llSetPrimitiveParams]]
| <lsl>llSetPrimitiveParams([PRIM_COLOR, ALL_SIDES, llGetColor(ALL_SIDES), 0.5]);</lsl>
| This will set the object's alpha to opaque; '''50%''' using the build tool.
|-
| [[llSetLinkPrimitiveParams]]
| <lsl>llSetLinkPrimitiveParams(LINK_SET, [PRIM_COLOR, ALL_SIDES, llGetColor(ALL_SIDES), 0.5]);</lsl>
| This will set the link-set's alpha to opaque; '''50%''' using the build tool.
