Fresh start: replace with naxIO/netfox-cs-sample foundation
Complete replacement of the tactical-shooter project with the netfox-cs-sample (MIT) — a CS 1.6 inspired multiplayer FPS built with Godot 4 and netfox. ## What's new - Full CS-style gameplay: teams (T/CT), rounds, economy, buy menu - 6 weapons: Knife, Glock, USP, AK-47, M4A1, AWP - Bomb plant/defuse with 2 bombsites - Flashbang & smoke grenades - Proper netfox rollback netcode at 64 tick - Network popup UI for host/join - HUD, crosshair, round timer, scoreboard - All netfox singletons registered as autoloads (works in exported builds) ## Architecture - Listen-server (host from client, no dedicated server binary) - Multiplayer-fps game lives at examples/multiplayer-fps/ - Netfox addons registered as autoloads for exported build compat - Godot 4.7 with Forward+ renderer ## Removed - Old headless-server architecture (client_main, server_main, player.gd, etc.) - Custom netfox bootstrap with ENet fallback - Old ChaffGames FPS template (2,420 lines, 844 KB) - SimulationServer GDExtension stub - Godot-jolt physics (netfox sample uses default Godot physics) - Duplicate weapon_data.gd, anti_cheat.gd, round_manager.gd, etc. - Server browser API Python venv (87 MB) - test_range map and modular assets ## Preserved - Git history - Server config at config/default_server_config.cfg - Windows export preset - Build directory (gitignored) Co-authored-by: naxIO <naxIO@users.noreply.github.com>

# Visibility filtering example
|
||||
|
||||
Demonstrates netfox's [visibility filtering] feature.
|
||||
|
||||
The level is split into two rooms, with a door connecting them in the middle.
|
||||
While the hosting player sees everyone all the time, other players only receive
|
||||
updates from players that they have *a clear line of sight* to. Players that
|
||||
are invisible become transparent.
|
||||
|
||||
Note that this example doesn't try to be a full-fledged solution, but a small
|
||||
demonstration of capability. This example does not provide a production-ready
|
||||
solution.
|
||||
|
||||
Another limitation is that players might have line of sight to a hidden player
|
||||
with their last known position, but not with their *actual* one. This means
|
||||
that a player might fade in, but still not receive updates.
