OCAP Addon

Arma 3 addon for Operation Capture and Playback (OCAP). Records gameplay data during missions for web-based playback analysis.

Note: For general OCAP information, documentation, and issue tracking, see the main repository: https://github.com/OCAP2/OCAP

Requirements

• Arma 3 2.10+
• CBA_A3
• OCAP Recorder Extension (for database export)
• Optional: ACE3 for enhanced medical state tracking

Installation

Download the latest release from GitHub Releases and place the @ocap folder in your Arma 3 directory.

Building from Source

Requires HEMTT:

hemtt build        # Development build
hemtt release      # Release build with signed PBOs

Configuration

All settings are configurable in-game via CBA Settings (Options > Addon Options > OCAP). Player Detail Tracking names and tooltips are stringtable entries (addons/recorder/stringtable.xml) so they follow the game language.

Key settings:

• Recording Enabled - Master toggle
• Auto Start Recording - Start recording when minimum player count is reached
• Minimum Player Count - Players required for auto-start
• Frame Capture Delay - Interval between position captures (seconds)

Player Detail Tracking

Optional per-player snapshots (gear, medical, stamina, radios) sampled on each client and stored as extra events. AI is not sampled. Defaults, intervals and the force block live in docs/player-detail-tracking.md.

Pinned production values:

force OCAP_settings_trackPlayerInventory = true;
force OCAP_settings_playerInventoryInterval = 120;
force OCAP_settings_trackPlayerInventoryOnDeath = true;
force OCAP_settings_trackPlayerMedical = true;
force OCAP_settings_playerMedicalInterval = 60;
force OCAP_settings_playerMedicalCriticalInterval = 10;
force OCAP_settings_trackPlayerStamina = true;
force OCAP_settings_playerStaminaInterval = 30;
force OCAP_settings_trackPlayerRadio = true;
force OCAP_settings_playerRadioInterval = 120;
force OCAP_settings_trackPlayerSnapshotDiffs = true;
force OCAP_settings_radioShortRangeMeters = 5000;
force OCAP_settings_radioLongRangeMeters = 20000;
force OCAP_settings_trackServerFps = true;
force OCAP_settings_trackWeather = true;

Server Performance

OCAP_settings_trackServerFps defaults to true. It records server diag_fps at recording start and every 10 seconds for the web playback Stats panel.

Weather

OCAP_settings_trackWeather defaults to true. It records vanilla weather (overcast, rain, fog, wind, humidity, moon phase) at recording start and every 60 seconds. When ACE Weather is loaded and ace_weather_enabled is on, ACE air temperature and humidity replace the vanilla readings. The Stats panel shows the sample at the playhead.
