Crowd Meter HUD LSL Script — Real-Time Region & Nearby Avatar Counter (Owner HUD, Easy Install)

Bring instant crowd intelligence to your Second Life events, clubs, stores and roleplay sims with the Crowd Meter HUD LSL Script — a lightweight, reliable HUD script that displays both the total number of avatars in the region and a precise nearby count (sensor), updated in real time. Designed for creators, event hosts and store owners who need a fast, readable display of how many people are in the sim and how many are close to the stage or shop, this script is simple to install, low-impact on server resources, and includes owner-only controls for quick reconfiguration while you run your venue.

Why this script? Many venue owners rely on rough estimates or manual checks. The Crowd Meter HUD automates counting with two complementary methods: it uses llGetAgentList(AGENT_LIST_REGION, []) to fetch the server-side region avatar total (accurate up to server update timing) and a repeating llSensorRepeat() to detect nearby avatars inside configurable radii. The combination gives you a reliable big-picture total and an accurate localized figure for the area immediately around your HUD — perfect for monitoring attraction levels, deciding when to start an event, or troubleshooting crowd flow.

Key behavior at a glance:

Region Count — server-side count of all avatars in the current region (uses llGetAgentList).

Nearby Count — sensor-based count of avatars within the HUD’s configurable radius (20, 48, 64, 96 meters by default).

Auto-Updating — both counts refresh automatically on intervals you can tune in the script.

Owner Controls — touch the HUD (owner only) to cycle sensor radii quickly while live.

Minimal Setup — drop the script into a HUD prim and attach; it shows readout with llSetText so the information is always visible.

Installation & Use

Rez a small prim and place the script inside, or add it to a HUD prim and attach to a HUD point (center, top, left, etc.).

On script start it will automatically perform its first counts and begin repeating the sensor and region polling at sensible defaults (5s for both sensor and region polling).

The owner may touch the HUD to cycle the sensor radius through preset values (20 → 48 → 64 → 96 m) to suit different venues — from intimate spaces to large dancefloors. Non-owners receive a short informational message on touch, keeping controls secure.

If you prefer faster updates, adjust the sensorRate and timerRate variables in the script (smaller values update more often at the expense of slightly more script activity). The default balances responsiveness and low overhead.

Why creators & venue owners pick this HUD

Event-ready: Know when to start a show or when to open a second stage by watching the nearby count grow.

Attraction analytics: Quickly compare region totals to nearby counts to measure how well your entrance, billboard or gacha area is pulling people inside.

Simple owner controls: Change the detection radius on the fly — no need to rez new objects or dig through notecards.

Low footprint & safe: Built using standard LSL calls with safe default rates and a simple structure so it behaves nicely across viewers and server conditions.

Extensible: The script is modular and easy for other scripters to extend (add dialog menus, chat commands, notecard-configured radii, texture swaps for big HUD digits, or notecard/database logging).

Customization ideas (easy tweaks you can make)

Replace the llSetText() hover display with face textures for larger fonts and stylized HUD visuals — ideal for sellers who want big, bold numbers on a HUD face.

Add dialog or chat menus so the owner can set custom sensor radii and update intervals without editing the script.

Push counts to a notecard or remote logging server (advanced) to keep historical attendance data.

Add visual or audio alerts when nearby or region counts surpass thresholds (e.g., “Start DJ” when 30 people are nearby).

Compatibility & Notes

Works in regular Second Life regions (sensors are region-limited). Sensor maximum radius and behaviour are limited by the viewer/server (the default list uses safe values up to 96m).

llSetText() size and font are viewer-controlled; if you need larger in-HUD fonts, use texture-based digits applied to HUD faces (the script can be adapted to swap textures).

Sensitive to scripting limits only when you lower the update interval drastically — sensible defaults are selected to keep the script friendly to other content on busy sims.

Support & Licensing
This script is provided as the core Crowd Meter HUD offering for creators who want a simple, ready-to-run solution. If you need the script adapted (dialog menu, texture-digit support, notecard config, logging to a remote service, or multi-zone sensing), contact the seller for paid customizations. The script is easy to integrate into your HUD builds or sell as part of a HUD product.

Perfect for

Club owners and DJs who want to monitor dancefloor traffic.
