Call of Duty 2 Multiplayer: Adding Animated Shutters and Swaying Wires Using Stock _shutter.gsc<\/h1>\n \n

This tutorial explains how to implement dynamic ambient effects (randomly jiggling shutters and swaying wires) in a CoD2 multiplayer map using the original stock script maps\/mp\/_shutter.gsc<\/code>. These effects add great life to maps, as seen in classics like mp_toujane. The script is already included in the stock PK3 files and always available\u2014no custom file placement required.<\/p>\n\n

1. Script Setup<\/h2>\n \n

The stock script maps\/mp\/_shutter.gsc<\/code> is automatically called by maps\\mp\\_load::main()<\/code>, which is included in every standard multiplayer map GSC. You do not<\/strong> need to add any extra line to your map’s main GSC file.<\/p>\n\n

\n

Important Warning:<\/strong> Do not<\/strong> manually add thread maps\\mp\\_shutter::main();<\/code> (or similar) to your map GSC. Doing so will run the script twice, causing duplicate rotations, wrong clamping, over-rotation (including full 360\u00b0 spins), crashes on restart, and blocking other map initialization (e.g. ambient sounds not loading).<\/p>\n <\/div>\n\n

\n

Note:<\/strong> The original script includes a commented-out windController()<\/code> thread that would periodically switch wind direction and fully open shutters in one direction. The developers left it disabled\u2014there may have been a good reason (e.g., performance, visual consistency, or gameplay concerns). The current behavior provides continuous random jiggle without directional resets.<\/p>\n <\/div>\n\n

2. Creating Swaying Wires<\/h2>\n \n

Wires use a script_brushmodel<\/code> linked to two script_origin<\/code> entities at each end.<\/p>\n \n

    \n
  1. Create a long thin brush for the wire (texture as cable\/metal).<\/li>\n
  2. Convert it to script > brushmodel<\/strong>.<\/li>\n
  3. Press N<\/strong>, set targetname<\/code> to wire<\/code>.<\/li>\n
  4. Create two point entities (right-click empty grid > info > any, then in N window change classname<\/code> to script_origin<\/code>).<\/li>\n
  5. Place one script_origin at each end of the wire.<\/li>\n
  6. On the wire entity, add target<\/code> key with a unique value (e.g., wire1_ends<\/code>).<\/li>\n
  7. On both script_origins, set targetname<\/code> to the same value (wire1_ends<\/code>).<\/li>\n
  8. Alternative: Select wire first, then both origins, press W<\/strong> to auto-link.<\/li>\n <\/ol>\n \n

    3. Creating Animated Shutters (Correct Pivot Method)<\/h2>\n \n

    Shutters rotate randomly around a custom hinge pivot defined by an origin-textured brush<\/strong>. No script_origins or targets needed.<\/p>\n \n

      \n
    1. Create the main shutter brush (rectangular, wood\/metal texture).<\/li>\n
    2. Position it in its closed\/rest pose against the wall or frame.<\/li>\n
    3. Create a small helper brush centered exactly on the hinge line (vertical edge for side swing, horizontal top edge for overhead).<\/li>\n
    4. Apply the origin<\/strong> texture to all faces<\/strong> of the helper brush (search “origin” in textures > common\/tools).<\/li>\n
    5. Select both<\/strong> brushes (shutter + origin helper).<\/li>\n
    6. Right-click > script > brushmodel<\/strong> (merges into one entity).<\/li>\n
    7. Press N<\/strong>, set targetname<\/code> to one of the supported values below.<\/li>\n <\/ol>\n \n \n \n \n \n \n \n \n \n \n \n
      Targetname<\/th>\n Grouping \/ Notes<\/th>\n <\/tr>\n <\/thead>\n
      shutter_left<\/code><\/td>\n Base left-facing (grouped as left)<\/td>\n <\/tr>\n
      shutter_right<\/code><\/td>\n Base right-facing (grouped as right)<\/td>\n <\/tr>\n
      shutter_left_open<\/code><\/td>\n Treated as left group<\/td>\n <\/tr>\n
      shutter_right_open<\/code><\/td>\n Treated as left group (script quirk)<\/td>\n <\/tr>\n
      shutter_left_closed<\/code><\/td>\n Treated as left group<\/td>\n <\/tr>\n
      shutter_right_closed<\/code><\/td>\n Treated as right group<\/td>\n <\/tr>\n <\/tbody>\n <\/table>\n \n

      \n

      Important:<\/strong> The origin brush is invisible in-game and only defines the rotation pivot. Test the hinge in Radiant using the R<\/strong> key (rotate mode) after merging\u2014drag in 3D view to confirm perfect swing before compiling.<\/p>\n <\/div>\n\n

      Final Steps<\/h2>\n \n
        \n
      • Duplicate and place multiple wires and shutters around your map for variety.<\/li>\n
      • Perform a full compile (BSP \u2192 VIS \u2192 Lighting).<\/li>\n
      • Launch with \/devmap yourmapname<\/code>.<\/li>\n
      • Enjoy subtle, realistic ambient movement!<\/li>\n <\/ul>\n\n

        If effects don’t appear or behave strangely (e.g. over-rotation, no ambient sound), enable \/developer 1<\/code> in console and check for script errors. Common issue: the script being called twice (once by _load.gsc and again manually).<\/p>\n<\/div>\n\n
