WaypointTool Documentation: Mastering Path Generation and Navigation Introduction
WaypointTool is a lightweight, high-performance pathfinding and navigation system. It simplifies AI movement, dynamic path generation, and waypoint management in modern game engines and simulation frameworks. This guide covers core concepts, setup steps, and advanced implementation techniques. Core Architecture The tool operates on three fundamental layers:
Waypoint Nodes: Individual data points representing specific coordinates in 3D or 2D space. Paths: Linear or branched collections of connected nodes.
Navigator Agents: Component scripts attached to entities that handle movement logic and obstacle avoidance. System Installation
Download the latest WaypointTool.unitypackage or Package.zip from the official repository.
Extract the contents into your project’s Plugins or Assets directory.
Open your project settings and ensure target framework compatibility is set to .NET 4.x or higher.
Verify installation by navigating to the top menu bar: Tools > WaypointTool > Configuration Window. Creating Your First Path Step 1: Initialize the Path Manager
Every scene requiring navigation must contain a single Path Manager instance. Go to Tools > WaypointTool > Create Path Manager. This object centralizes baking operations and global path visualization. Step 2: Placing Waypoints Select the Path Manager game object.
Hold the Shift key and Left-Click anywhere on your scene geometry to drop your first node. Continue clicking to automatically chain nodes together.
To close a loop, select your final node and check the Is Loop box in the inspector panel. Step 3: Configuring Node Properties
Each node holds individual metadata to alter agent behavior:
Speed Modifier: Multiplier for agent speed when approaching the node.
Wait Time: Duration in seconds an agent pauses before moving to the next target.
Action Trigger: UnityEvent or callback hook executed upon agent arrival. Scripting API Guide Basic Movement Setup
To attach an entity to a path via code, reference the WaypointNavigator namespace.
using WaypointTool; using UnityEngine; public class EnemyAI : MonoBehaviour { public WaypointPath activePath; private WaypointNavigator navigator; void Start() { navigator = GetComponent Use code with caution. Runtime Path Modification
Paths can be generated or altered dynamically during gameplay to adapt to changing environments.
// Generate a new node at runtime WaypointNode dynamicNode = activePath.CreateNode(new Vector3(10f, 0f, 5f)); // Insert the node at a specific index in the sequence activePath.InsertNodeAt(2, dynamicNode); // Recalculate path curves immediately activePath.BakePathCurves(); Use code with caution. Advanced Features Spline Interpolation
Smooth sharp geometric angles by switching the path type from Linear to Bezier Spline or Catmull-Rom in the path inspector. This generates smooth, natural curves perfect for cinematic cameras or organic creature movement. Dynamic Obstacle Avoidance
When an obstacle blocks a path segment, enable the Local Avoidance flag on the navigator agent. The system will cast raycasts forward and temporarily deviate from the waypoint path to steer clear of collision boxes, snapping back to the track once past the obstruction. Troubleshooting Agents Are Jerking or Stuttering Cause: The Arrival Distance threshold is set too low.
Solution: Increase the threshold value in the navigator settings to at least 0.2f. Paths Disappear in Play Mode
Cause: Gizmo rendering is disabled or the path manager is being cleared on scene loads.
Solution: Ensure Draw Gizmos is toggled on in the game view window, and check that Persist on Load is checked on the Path Manager component.
