Scripting Features

Since texture transforms aren't part of the PBR asset, we can't just use the "" hack in llSetLinkPrimitiveParamsFast(...) to preserve their values. Instead we need to record the transforms (offset/repeats/rotation) for each face and reapply them with the new alpha value. A function like llSetLinkPBRAlpha() would be very much appreciated. Coming to think if it, most use cases (except for fading) could actually be addressed by having something like llLinkVisible(LINK_THIS, ALL_SIDES, TRUE) - llLinkVisible(LINK_THIS, ALL_SIDES, FALSE) - taking the usual LINK_* constants and face numbers.

Rationale We have sit targets to define where an avatar should sit on a linked object. But when standing up, it's always at that exact same position. This is awkward for things like vehicles where the user will unsit inside the vehicle instead of stepping out gracefully. This goes together with a possible unsit event as proposed here: https://feedback.secondlife.com/scripting-features/p/unsit-events Proposal Add a possibility to let us define the exact spot and rotation where the avatar will be positioned/moved to at the moment of unsitting.

Add a new function LSL function named llRenderText or similar, which allows users to dynamically render text, with limited but flexible formatting, onto the face of their choosing. Concept: // Signature llRenderText(integer face, string text, list params); // Basic example llRenderText(ALL_FACES, "Lorem ipsum...", [ FONT_ALIGN, "right", FONT_WEIGHT, "bold", FONT_FAMILY, "sans serif" ]); Rationale Text is ubiquitous, yet Second Life has no way for users to display text other than uploading a texture, setting floating text using llSetText , or using relatively resource intensive solution such as XyText/Furware/et al. This absence precludes interesting features, such as being able to create a responsive interactive terminal in Second Life, HUDs with dynamic text, etc. A scripted and efficient text solution that displays on the face of a prim/mesh would give Second Life the biggest bang for the buck: Limited in scope (easier to implement than grand UI-creation ideas) Easy to kitbash into existing and new creations For inspiration, you can look to how the Text Display widget is implemented in the Playstation game Dreams. It has limited options: a finite number of fonts and formatting options, but the fact that it can be combined with other content makes it rather powerful. Other details Font color, opacity, glow, etc are controlled by prim properties (Example: setting face color to red sets font color to red) Questions Should the background always be transparent? Creators could put another prim behind the text display face to give it a background, or it could be a property of the render params. Possible Parameters FONT_WEIGHT FONT_STYLE FONT_FAMILY FONT_VERTICAL_ALIGN FONT_HORIZONTAL_ALIGN FONT_TEXT_WRAP FONT_LINE_HEIGHT FONT_SIZE Possible Features Markdown / rich text

I've spent about the last week updating some scripts to handle both PBR and Blinn-Phong updates simultaneously. The scripts work fine, but the current way you have to update PBR values - through llSetPrimitiveParams and the full list of values - is not ideal. In order to avoid overwriting your existing values with blank or incorrect data, you have to have a way to know and store your existing values, modify those values, and send the whole list back in. Adding in some llFunctions for PBR values, so you don't have to modify the entire parameter array to change one value, would make scripting PBR modifications much more pleasant to work with. If llFunctions are not feasible, a way to update individual values in the parameter arrays without data loss (e.g. being able to pass a blank string as a texture and have it skip the value instead of applying it) would be appreciated. I've compiled a list below of how I would personally pop each value out into a Set function (they would have matching Get functions, a la llGetColor and llSetColor): --- For PRIM_GLTF_BASE_COLOR: llSetGLTFBaseTexture(string texture, vector repeats, vector offsets, float rotation_in_radians, integer face); llSetGLTFBaseColor(vector color, integer face); llSetGLTFBaseAlphaMode(integer gltf_alpha_mode, integer face); llSetGLTFBaseAlpha(float alpha, integer face); llSetGLTFBaseAlphaMask(float alpha_mask_cutoff, integer face); llSetGLTFBaseDoubleSided(integer double_sided, integer face); --- For PRIM_GLTF_NORMAL (this really only has one function): llSetGLTFNormal(string texture, vector repeats, vector offsets, float rotation_in_radians, integer face); --- For PRIM_GLTF_METALLIC_ROUGHNESS: llSetGLTFMetalRoughTexture(string texture, vector repeats, vector offsets, float rotation_in_radians, integer face); llSetGLTFMetallicFactor(float metallic_factor, integer face); llSetGLTFRoughnessFactor(float roughness_factor, integer face); --- For PRIM_GLTF_EMISSIVE: llSetGLTFEmissiveTexture(string texture, vector repeats, vector offsets, float rotation_in_radians, integer face); llSetGLTFEmissiveTint(float emissive_tint, integer face);

Add the ability to receive input from game controllers such as joysticks, Xbox controllers, etc. This will allow the creation ofhHelicopters and planes that use analog input from console controllers, attachments that control drones, arcade games, cranes, machinima puppetry, etc. This new feature will be implemented by adding a LSL event game_control(...) which script authors can use to capture and respond to input from users. For further details, see https://wiki.secondlife.com/wiki/Game_control

It would be great if we could have "signed" or "named" timers, so we can distinguish timer events from each other. So we could have: llSetSignedTimerEvent(float timeout,integer signature) signed_timer(integer signature) { } or: key llSetKeyedTimerEvent(float timeout) llUpdateKeyedTimerEvent(key id, float timeout) keyed_timer(key timer_key) { } Whatever is easier to implement. Personally I would like the arbitrary signed timer best, with a limit of 8 or 16 simultaneous timers if needed.

The existing mono memory cap of 64kb per script is based on simulator hardware that is no longer in use. The 64k limit is regularly subject to workarounds by use of 'slave' scripts to hold on to memory, at excessive cost to performance, from having multiple scripts doing the job of one, resulting in a net loss of performance versus a single script with increased memory. Is there any possibility that this could be increased, even slightly?

Currently, we have no way to rotate the avatar. This function would rotate the owner of the script on the Z-axis and would work as an attachment. With this, we can rotate the avatar to the surface normal of a wall, table, or other avatars without the need to use RLV functions that manipulate the camera or having to sit and unsit the avatar. This would allow for things like wall climbing and a host of other useful applications. https://gyazo.com/7d441967232c304a4fa20ce722ec18ce rotation RotNormal(vector _normal){ vector vLeft = llVecNorm( _normal % llRot2Fwd(llGetRot())); vector vFwd = vLeft % _normal; rotation rRot = llAxes2Rot(vFwd, vLeft, _normal); return rRot; } wall_climb() { vector scale = llGetAgentSize(owner); vector vStart = llGetPos() + <scale.x/2,0,scale.z/2> * llGetRot(); vector vEnd = vStart + <0.25,0,-1.0> * llGetRot(); list CN = llCastRay(vStart, vEnd, [RC_DATA_FLAGS,RC_GET_NORMAL, RC_MAX_HITS, 1]); float FW_Dist = llVecDist(vStart,llList2Vector(CN, 1) + <scale.x/2,0,0> * RotNormal(llList2Vector(CN, 2))); /* Set the position and agent rotation to the surface normal of the detected object. */ }

With the introduction of PBR and new features in SL the The 64k memory limit is becoming increasingly hard to work with and not suitable for modern designs. When designing more feature intensive HUDS its hard not to keep running out of memory, suggestion to double or increase the limit would be very much welcome for 2024.

Texture animation is a widely used technique in various games and virtual worlds. It allows for dynamic and visually appealing effects that can greatly enhance the immersive experience for users. Enabling texture animation in the particle system, content creators would be able to create even more captivating and engaging environments. llParticleSystem is already using list for its setting. So I suggest [TEXTURE_ANIM, mode, sizex, sizey, start, length, rate] to be added for that option.
