Sandbox++
Released
An open-source, community-driven successor to GMod's Sandbox. Work in progress!
Npcs/Npc.Layers.cs
Partial NPC component that exposes required subcomponents for AI behavior. It declares SensesLayer, NavigationLayer, AnimationLayer, and SpeechLayer properties with RequireComponent attributes so the NPC will have those layers attached.
using Sandbox.Npcs.Layers;
namespace Sandbox.Npcs;
public partial class Npc : Component
{
/// <summary>
/// Senses layer - handles environmental awareness and target detection
/// </summary>
[RequireComponent]
public SensesLayer Senses { get; set; }
/// <summary>
/// Navigation layer - handles pathfinding and movement
/// </summary>
[RequireComponent]
public NavigationLayer Navigation { get; set; }
/// <summary>
/// Animation layer - handles look-at and animation parameters
/// </summary>
[RequireComponent]
public AnimationLayer Animation { get; set; }
/// <summary>
/// Speech layer - handles talking, lipsync, etc..
/// </summary>
[RequireComponent]
public SpeechLayer Speech { get; set; }
