  1. /************************************************************
  2.  
  3. RWR and spoofing script: Based on Franze's Su-17/22 RWR script!
  4.  
  5. Updated by HCPOOKIE to work with:
  6.  - POOK_EF2000
  7.  - POOK Soviet AF
  8.  - VME_PLA Vehicles
  9.  - Fuller's USAF mod
  10.  - Other mods can employ this script as well.
  11.  
  12. Please credit appropriately.
  13.  
  14. ///////////////////////////////////
  15. * This is the POOK_SovAF version!!!
  16. ///////////////////////////////////
  17.  
  18. USAGE:
  19.  - Action-based script to attempt to spoof incoming missiles
  20. `
  21.  - Relies on two other functions which must be loaded on INIT:
  22. EF2K_pitchbank = compile preprocessFileLineNumbers "\mod\scripts\fsetpitch.sqf";
  23. EF2K_getpb = compile preprocessFileLineNumbers "\mod\scripts\frotate.sqf";
  24.  
  25.  - Checks for certain jammer pods on plane; if none, checks
  26.    if plane is of certain types that contain on-board jamming
  27.    equipment; if neither, revert to default action
  28.  
  29.  - Reads missile attributes to determine if the following
  30.    POOK_SAM pack values are present, and modify behavior
  31.    accordingly (see POOK_SAM pack documentation for more info):
  32.    - POOK_HOJ
  33.    - POOK_Band
  34.    - POOK_HOP
  35.  
  36.  - Missiles have chance to burn-through jamming, making results
  37.    semi-random.  Pilots should plan to adjust flight to dodge
  38.    missiles, and employ standard countermeasures while jamming.
  39.  
  40.  - Script also provides RWR notification to pilot and animates
  41.    on-board RWR cockpit indicators if so equipped.
  42.  
  43.  - Pilot also receives vehicle chat notifications regardless
  44.    if the plane has an animated RWR system.
