NavMeshAgent Basics

  • Destination Setting: Where agents should go
  • Speed Control: How fast they move
  • Rotation Management: How they turn
  • Stopping Distance: When to stop moving
  • Path Following: How to traverse paths

Advanced Pathfinding

  • Path Calculation: Finding optimal routes
  • Corner Smoothing: No robotic turns
  • Area Masking: Define walkable areas
  • Path Status: Check if paths are possible
  • Distance Computing: Calculate path lengths

Obstacle System

  • Dynamic Carving: Update paths around moving objects
  • Size Adjustment: Scale obstacle influence
  • Movement Thresholds: When to recalculate
  • Carving Time: When to update navigation
  • Center Position: Where obstacles affect paths

Off-Mesh Links

  • Link Traversal: Special path connections
  • Auto Navigation: Smart pathfinding
  • Manual Controls: Override automatic behavior
  • State Checking: Monitor link status
  • Link Activation: Control when links work

Common Mistakes

  • Missing Bakes: Forgetting to create NavMesh
  • Wrong Radius: Agents getting stuck
  • Too Many Requests: Performance issues
  • Unhandled Obstacles: Walking through walls
  • Poor Areas: Inefficient navigation

Performance Tips

  • Control Path Updates: Don't recalculate every frame
  • Use Priority: Important agents first
  • Optimize Quality: Balance accuracy vs speed
  • Update Frequency: When to refresh paths
  • Runtime Changes: Handle dynamic environments
