Random Spawn Children On NavMesh

Menu Path: GameObject > LogicCuteGuy > Random Spawn Children On NavMesh

Automate the placement of environment props, collectibles, or NPCs by randomly distributing child objects onto a baked NavMesh.

Features​

  • NavMesh-Aware: Uses Unity's NavMesh system to ensure objects are placed on walkable surfaces.
  • Placement Modes:
    • Local Radius: Samples positions around a specific center point.
    • Full NavMesh: Distributes objects across the entire triangulated NavMesh area of the scene.
  • Fine-Tuning:
    • Height Offset: Hover objects above or sink them into the ground.
    • Vertical Jitter: Randomize vertical sampling height for tiered or sloped terrains.
    • Max Sample Distance: Control how far objects can scatter.
  • Agent & Area Filtering: Select specific NavMesh Agent types and Area Masks (e.g., only spawn on "Grass" areas).

How to Use​

  1. Ensure your NavMesh is Baked.
  2. Select a Parent Object containing the children you want to scatter.
  3. Configure the Agent Type and Area Mask.
  4. Click Random Spawn Children.

[!NOTE] If placement fails for specific objects (e.g., no valid NavMesh nearby), the tool will report the failure count in a summary dialog.
