EOS Anti-Cheat protects the game client and lets the server check that clients are protected. The game must be started through the Anti-Cheat launcher with a protected build, see the EOS documentation for how to set this up.

warning

Anti-Cheat needs an external account. A DeviceId login is not enough, see DeviceId.

Client-Server Mode​

Use this mode with a dedicated or listen server.

Server (AntiCheatServer nodes):

  1. EOS_AntiCheatServer_AddNotifyMessageToClient: send the message to that client over your own network channel (for example a reliable RPC)
  2. EOS_AntiCheatServer_AddNotifyClientActionRequired: kick the client when EOS asks for it
  3. EOS_AntiCheatServer_BeginSession when the server starts
  4. EOS_AntiCheatServer_RegisterClient for each connecting player, EOS_AntiCheatServer_UnregisterClient when they leave
  5. EOS_AntiCheatServer_ReceiveMessageFromClient for each anti-cheat message from a client
  6. EOS_AntiCheatServer_EndSession when the server stops

Client (AntiCheatClient nodes):

  1. EOS_AntiCheatClient_AddNotifyMessageToServer: send the message to the server over your own network channel
  2. EOS_AntiCheatClient_BeginSession in client-server mode when you connect, EOS_AntiCheatClient_EndSession when you leave
  3. EOS_AntiCheatClient_ReceiveMessageFromServer for each anti-cheat message from the server
  4. EOS_AntiCheatClient_AddNotifyClientIntegrityViolated: the client is not protected

Peer-to-Peer Mode​

Without a trusted server, every client registers the other players with EOS_AntiCheatClient_RegisterPeer, and forwards messages with EOS_AntiCheatClient_AddNotifyMessageToPeer and EOS_AntiCheatClient_ReceiveMessageFromPeer.

Gameplay Events​

The server can send gameplay events to the Anti-Cheat backend for analysis, for example EOS_AntiCheatServer_LogPlayerSpawn, EOS_AntiCheatServer_LogPlayerTakeDamage, EOS_AntiCheatServer_LogGameRoundStart and EOS_AntiCheatServer_LogGameRoundEnd.

Reports and Sanctions​

Players can report each other with EOS_Reports_SendPlayerBehaviorReport. Use EOS_Sanctions_QueryActivePlayerSanctions to check if a player is banned, and the EOSCore Web sanctions functions to create sanctions from a server or tool.
