GridForge 1.0.3

GridForge

A high-performance, deterministic spatial grid management system for simulations and game development.

🚀 Key Features

• Deterministic Execution – Supports lockstep simulation and fixed-point arithmetic.
• Optimized Grid Management – Low memory allocations, spatial partitioning, and fast queries.
• Multi-Layered Grid System – Dynamic, hierarchical, and persistent grids.
• Node-Based Spatial Queries – Retrieve occupants, obstacles, and meta-data partitions efficiently.
• Custom Blockers & Partitions – Define obstacles and attach metadata dynamically.
• Framework Agnostic – Works with Unity, Lockstep Engines, and .NET-based frameworks.

📦 Installation

Non-Unity Projects

1. Install via NuGet:

   dotnet add package GridForge
   

2. Or Download/Clone:

   git clone https://github.com/mrdav30/GridForge.git
   

3. Include in Project:
   • Add GridForge to your solution or reference its compiled DLL.

Unity

GridForge is maintained as a separate Unity package. For Unity-specific implementations, refer to:

🔗 GridForge-Unity Repository.

🧩 Dependencies

GridForge depends on the following libraries:

• FixedMathSharp
• SwiftCollections

These dependencies are automatically included when installing.

📖 Library Overview

🗂 Core Components

| Component | Description | |-----------|------------| | GlobalGridManager | Manages grids, nodes, & spatial queries. | | Grid | Represents a single grid containing nodes & scan cells. | | Node | Represents a grid position, storing occupants, obstacles, & state. | | ScanCell | Handles spatial indexing for faster queries. | | GridTracer | Efficiently retrieves covered nodes, scan cells, & paths. | | GridObstacleManager | Manages grid-wide obstacles dynamically. | | GridOccupantManager | Handles occupant tracking & retrieval. | | ScanManager | Optimized scan queries for spatial lookups. | | Blockers | Defines dynamic and static obstacles. | | Partitions | Adds meta-data and custom logic to nodes. |

📖 Usage Examples

🔹 Creating a Grid

GridConfiguration config = new GridConfiguration(new Vector3d(-10, 0, -10), new Vector3d(10, 0, 10));
GlobalGridManager.TryAddGrid(config, out ushort gridIndex);

🔹 Querying a Grid for Nodes

Vector3d queryPosition = new Vector3d(5, 0, 5);
if (GlobalGridManager.TryGetGridAndNode(queryPosition, out Grid grid, out Node node))
	Console.WriteLine($"Node at {queryPosition} is {(node.IsOccupied ? "occupied" : "empty")}");
}

🔹 Adding a Blocker

BoundingArea blockArea = new BoundingArea(new Vector3d(3, 0, 3), new Vector3d(5, 0, 5));
Blocker blocker = new Blocker(blockArea);
blocker.ApplyBlockage();

🔹 Attaching a Partition to a Node

if (GlobalGridManager.TryGetGrid(queryPosition, out Grid grid, out Node node))
{
    PathPartition partition = new PathPartition();
    partition.Setup(node.GlobalCoordinates);
    node.AddPartition(partition);
}

🔹 Scanning for Nearby Occupants

Vector3d scanCenter = new Vector3d(0, 0, 0);
Fixed64 scanRadius = (Fixed64)5;
foreach (INodeOccupant occupant in ScanManager.ScanRadius(scanCenter, scanRadius))
{
    Console.WriteLine($"Found occupant at {occupant.WorldPosition}");
}
