Getting Started

Objective Waypoint System is a Blueprint asset package you migrate from the FAB project into your own Unreal Engine game. The only asset you must migrate is BP_WaypointComponent — it handles nav-mesh queries and waypoint rendering.

Prerequisites

• A level with a built Nav Mesh Bounds Volume and generated navigation mesh.
• A player Character or Pawn Blueprint where you can add components.

Migrate the component

1. Add Objective Waypoint System from FAB and open the project.
2. In Content Browser, go to Content/ObjectiveWaypointSystem/Blueprints.
3. Right-click BP_WaypointComponent → Asset Actions → Migrate.
4. Select your project’s Content folder and confirm dependencies (includes BP_WaypointActor, ENavMode, meshes, and materials).

Add to your pawn

1. Open your player character Blueprint.
2. Add Component → search BP_WaypointComponent (or drag from Content Browser).
3. Select the component and review Class Defaults:

Property	Description
Nav Filter Class	Limit pathfinding to a specific navigation query filter class. Default: None (all nav areas).
Tick Time	When > 0, pathfinding runs automatically every N seconds. Default: 0 (manual calls only).
Nav Mode	Spawn — place BP_WaypointActor markers. SplineMesh — deform mesh segments along the path.
Max Number Of Meshes	Maximum spawned markers in Spawn mode. Default: 60. 0 tries to fill the entire path (not recommended).
Mesh Distance	Spacing between markers in world units. Default: 250. Only applies in Spawn mode.
Draw Debug Strings	Show debug labels on spawned actors. Default: false.

Call pathfinding

Once the component is on your pawn, your game logic decides when and where to navigate. Call one of the Blueprint events on BP_WaypointComponent:

Event	Inputs	Use when
Find Path to Actor	Target Actor, optional Spline Component	Quest objective, NPC, interactable
Find Path to Location	Vector location, optional Spline Component	Map ping, minimap click, custom marker

The shipped ThirdPersonCharacter wraps these calls with objective selection and HUD toggles — use it as a reference, not a required dependency.

Example: press F to path to the current objective (from the demo project):

sequenceDiagram
  participant Input as Input / quest logic
  participant Pawn as Your character
  participant WC as BP_WaypointComponent
  Input->>Pawn: Target actor or location ready
  Pawn->>WC: Find Path to Actor (Actor, Spline)
  WC->>WC: Query nav mesh + spawn visuals

Try the demo first (recommended)

Before migrating, press Play on Map/Overview in the FAB project:

Key / action	Behaviour
F	Find path to Objective Actor (or first BP_ObjectiveActor in level)
Minimap click	Find path to clicked world location
Move	Third-person locomotion with camera
