API Overview

Complete reference for the CS2-SimpleAdmin API (ICS2_SimpleAdminApi).

Introduction

The CS2-SimpleAdmin API is exposed via the ICS2_SimpleAdminApi interface, accessible through CounterStrikeSharp's capability system.

Getting the API

Using Capability System

using CounterStrikeSharp.API.Core;
using CounterStrikeSharp.API.Core.Capabilities;
using CS2_SimpleAdminApi;

public class YourPlugin : BasePlugin
{
    private ICS2_SimpleAdminApi? _api;
    private readonly PluginCapability<ICS2_SimpleAdminApi> _pluginCapability =
        new("simpleadmin:api");

    public override void OnAllPluginsLoaded(bool hotReload)
    {
        _api = _pluginCapability.Get();

        if (_api == null)
        {
            Logger.LogError("CS2-SimpleAdmin API not found!");
            Unload(false);
            return;
        }

        // API is ready to use
        RegisterFeatures();
    }
}

Static Capability Reference

// Alternative approach
var capability = ICS2_SimpleAdminApi.PluginCapability;
var api = capability?.Get();

Common Patterns

Basic Module Structure

using CounterStrikeSharp.API.Core;
using CounterStrikeSharp.API.Core.Capabilities;
using CS2_SimpleAdminApi;

namespace MyModule;

public class MyModule : BasePlugin
{
    private ICS2_SimpleAdminApi? _api;
    private readonly PluginCapability<ICS2_SimpleAdminApi> _pluginCapability =
        new("simpleadmin:api");

    public override string ModuleName => "My Module";
    public override string ModuleVersion => "1.0.0";

    public override void OnAllPluginsLoaded(bool hotReload)
    {
        _api = _pluginCapability.Get();
        if (_api == null) return;

        // Register features
        RegisterCommands();

        // Wait for SimpleAdmin ready
        _api.OnSimpleAdminReady += RegisterMenus;
        RegisterMenus();  // Fallback for hot reload
    }

    public override void Unload(bool hotReload)
    {
        if (_api == null) return;

        // Cleanup
        _api.UnRegisterCommand("css_mycommand");
        _api.UnregisterMenu("category", "menu");
        _api.OnSimpleAdminReady -= RegisterMenus;
    }
}

---

Command with Target Selection

[CommandHelper(1, "<#userid or name>")]
[RequiresPermissions("@css/generic")]
private void OnMyCommand(CCSPlayerController? caller, CommandInfo command)
{
    // Parse targets
    var targets = _api!.GetTarget(command);
    if (targets == null) return;

    // Filter valid players
    var players = targets.Players
        .Where(p => p.IsValid && !p.IsBot && caller!.CanTarget(p))
        .ToList();

    // Process each player
    foreach (var player in players)
    {
        DoSomethingToPlayer(caller, player);
    }

    // Log command
    _api.LogCommand(caller, command);
}

---

Menu with Player Selection

private object CreateMyMenu(CCSPlayerController admin, MenuContext context)
{
    // Context contains categoryId, menuId, menuName, permission, commandName
    return _api!.CreateMenuWithPlayers(
        context,  // Automatic title and category
        admin,
        player => player.IsValid && admin.CanTarget(player),
        (admin, target) =>
        {
            // Action when player selected
            PerformAction(admin, target);
        }
    );
}

---

Nested Menu

private object CreatePlayerMenu(CCSPlayerController admin, MenuContext context)
{
    var menu = _api!.CreateMenuWithBack(context, admin);

    var players = _api.GetValidPlayers()
        .Where(p => admin.CanTarget(p));

    foreach (var player in players)
    {
        _api.AddSubMenu(menu, player.PlayerName, admin =>
        {
            return CreateActionMenu(admin, player);
        });
    }

    return menu;
}

private object CreateActionMenu(CCSPlayerController admin, CCSPlayerController target)
{
    var menu = _api!.CreateMenuWithBack($"Actions for {target.PlayerName}", "category", admin);

    _api.AddMenuOption(menu, "Action 1", _ => DoAction1(admin, target));
    _api.AddMenuOption(menu, "Action 2", _ => DoAction2(admin, target));

    return menu;
}

---

Issue Penalty

private void BanPlayer(CCSPlayerController? admin, CCSPlayerController target, int duration, string reason)
{
    // Issue ban
    _api!.IssuePenalty(
        target,
        admin,
        PenaltyType.Ban,
        reason,
        duration  // minutes, 0 = permanent
    );

    // Show activity
    if (admin == null || !_api.IsAdminSilent(admin))
    {
        _api.ShowAdminActivityLocalized(
            Localizer,
            "ban_message",
            admin?.PlayerName,
            false,
            target.PlayerName,
            duration
        );
    }
}

---

Event Subscription

public override void OnAllPluginsLoaded(bool hotReload)
{
    _api = _pluginCapability.Get();
    if (_api == null) return;

    // Subscribe to events
    _api.OnPlayerPenaltied += OnPlayerPenaltied;
}

private void OnPlayerPenaltied(
    PlayerInfo player,
    PlayerInfo? admin,
    PenaltyType type,
    string reason,
    int duration,
    int? penaltyId,
    int? serverId)
{
    Logger.LogInformation($"{player.PlayerName} received {type}: {reason} ({duration} min)");

    // React to penalty
    if (type == PenaltyType.Ban)
    {
        // Handle ban
    }
}

public override void Unload(bool hotReload)
{
    if (_api == null) return;
    _api.OnPlayerPenaltied -= OnPlayerPenaltied;
}

---

Best Practices

1. Always Check for Null

if (_api == null)
{
    Logger.LogError("API not available!");
    return;
}

2. Use OnSimpleAdminReady Event

_api.OnSimpleAdminReady += () =>
{
    // Register menus only when SimpleAdmin is ready
    RegisterMenus();
};

// Also call directly for hot reload case
RegisterMenus();

3. Clean Up on Unload

public override void Unload(bool hotReload)
{
    if (_api == null) return;

    // Unregister all commands
    _api.UnRegisterCommand("css_mycommand");

    // Unregister all menus
    _api.UnregisterMenu("category", "menu");

    // Unsubscribe all events
    _api.OnSimpleAdminReady -= OnReady;
}

4. Validate Player State

if (!player.IsValid || !player.PawnIsAlive)
{
    return;
}

if (!caller.CanTarget(player))
{
    return;  // Immunity check
}

5. Use Per-Player Translations

// Each player sees message in their configured language
_api.ShowAdminActivityLocalized(
    Localizer,  // Your module's localizer
    "translation_key",
    caller?.PlayerName,
    false,
    args
);

6. Log All Admin Actions

_api.LogCommand(caller, command);
// or
_api.LogCommand(caller, $"css_mycommand {player.PlayerName}");

API Versioning

The API uses semantic versioning:

• Major - Breaking changes
• Minor - New features, backwards compatible
• Patch - Bug fixes

Current Version: Check GitHub Releases

---

Thread Safety

The API is designed for single-threaded use within the CounterStrikeSharp game thread.

Do NOT:

• Call API methods from background threads
• Use async/await with API calls without proper synchronization

Do:

• Call API methods from event handlers
• Call API methods from commands
• Call API methods from timers

---

Error Handling

The API uses exceptions for critical errors:

try
{
    _api.RegisterCommand("css_cmd", "Desc", callback);
}
catch (ArgumentException ex)
{
    Logger.LogError($"Failed to register command: {ex.Message}");
}

Common exceptions:

• ArgumentException - Invalid arguments
• InvalidOperationException - Invalid state
• KeyNotFoundException - Player not found

---

Performance Considerations

Efficient Player Filtering

// ✅ Good - single LINQ query
var players = _api.GetValidPlayers()
    .Where(p => p.IsValid && admin.CanTarget(p))
    .ToList();

// ❌ Bad - multiple iterations
var players = _api.GetValidPlayers();
players = players.Where(p => p.IsValid).ToList();
players = players.Where(p => admin.CanTarget(p)).ToList();

Cache Expensive Operations

// Cache menu creation if used multiple times
private object? _cachedMenu;

private object GetMenu(CCSPlayerController player)
{
    if (_cachedMenu == null)
    {
        _cachedMenu = CreateMenu(player);
    }
    return _cachedMenu;
}

---

Debugging

Enable Detailed Logging

Logger.LogInformation("Debug: API loaded");
Logger.LogWarning("Warning: Player not found");
Logger.LogError("Error: Failed to execute command");

Check API Availability

public override void OnAllPluginsLoaded(bool hotReload)
{
    _api = _pluginCapability.Get();

    if (_api == null)
    {
        Logger.LogError("❌ CS2-SimpleAdmin API not found!");
        Logger.LogError("Make sure CS2-SimpleAdmin is installed and loaded.");
        return;
    }

    Logger.LogInformation("✅ CS2-SimpleAdmin API loaded successfully");
}
