Vortex HUD & Floater UI Designer Pro

The Vortex HUD & Floater UI Designer Pro is an enterprise-grade visual interface creation suite developed specifically for Second Life and OpenSim content creators, scripters, and game developers. It enables the rapid visual prototyping, drag-and-drop assembly, tactile touch simulation, and 1-click compilation of production-ready Linden Scripting Language (LSL) scripts.

Traditional Second Life HUDs frequently suffer from extreme script memory bloat and region lag due to the legacy practice of inserting separate LSL scripts inside every individual child prim button.

• ▸Single Master Script: Only the root prim (Link 1) contains an active LSL script.
• ▸Touch Event Interception: When an avatar clicks any child prim, the master script intercepts the interaction via llDetectedLinkNumber() and llDetectedTouchFace().
• ▸Zero Script Memory Overhead: Even a 60-button complex MMORPG HUD operates at virtually 0.002ms script execution time and consumes less than 64KB of Mono memory.

// Centralized Touch Dispatcher Example
touch_start(integer total_number)
{
    integer i;
    for (i = 0; i < total_number; ++i)
    {
        integer linkNum = llDetectedLinkNumber(i);
        key toucher = llDetectedKey(i);
        
        if (linkNum == 2) // Health Flask Button
        {
            llMessageLinked(LINK_SET, 1002, "USE_POTION_HEALTH", toucher);
        }
    }
}

Second Life supports 8 standard screen attachment points. Vortex HUD Designer Pro features built-in coordinate grids and safe-area guidelines matching standard avatar viewports:

1. 01HUD Bottom Center (Standard): Ideal for MMORPG combat status bars, hotkey skill docks, and vehicle dashboards.
2. 02HUD Center & Center 2: Primary location for modal dialogue menus, vendor floaters, and gacha payout windows.
3. 03HUD Top Left: Recommended for Animation Overriders (AO), radar minimaps, and compass navigation.
4. 04HUD Top Right: Perfect for player identity cards, faction crests, and currency balances.
5. 05HUD Bottom Left & Bottom Right: Suitable for compact corner utilities, radio stream selectors, and chat toggles.

• ▸Zero Clipping: Scales the prim along the X-axis (PRIM_SIZE) while adjusting the local position offset (PRIM_POS_LOCAL), ensuring the bar depletes realistically from right to left without moving the center anchor.
• ▸Sub-Face Color Gradient: Supports 32-bit gradient textures with UV coordinate offsets for dynamic color transitions (e.g. Green > Yellow > Red).

• ▸Tactile Titlebars: Clicking the minimize icon reduces the floater window height to a compact titlebar strip (<0.3, 0.05, 0.02>).
• ▸Alpha Tweening: Smoothly fades child content prims using PRIM_COLOR alpha transitions to preserve viewer screen space during intense combat or social interaction.

1. 01Design your Layout: Arrange your buttons, bars, and floaters on the canvas and set target action triggers (LinkMessages, Dialogues, Sounds, or Whispers).
2. 02Compile LSL: Click Generate LSL and copy HUD_Master_Controller.lsl.
3. 03Rez Prims In-World: Rez your root base prim and child buttons according to the link numbers indicated in the designer.
4. 04Link the Object: Select all child prims first, select the Root Prim LAST, and press Ctrl+L to link.
5. 05Drop Script & Attach: Place HUD_Master_Controller.lsl into the Root Prim, right-click the item in your inventory, and select Attach to HUD!
