Navigation and Pathfinding Systems for Games
Nothing breaks immersion faster than NPCs walking through walls or getting stuck on stairs. Kreonit builds robust navigation and pathfinding systems that make every character in your game move intelligently, naturally, and efficiently through any environment.
Pathfinding Algorithms We Implement
We select pathfinding solutions based on your game’s specific requirements — world size, agent count, dynamic obstacles, and performance budget. No one-size-fits-all approach; every game gets the right tool for the job.
Navigation Services
- A* pathfinding implementation and optimization
- NavMesh generation and baking (Unity, Unreal)
- Hierarchical pathfinding (HPA*) for large worlds
- Dynamic obstacle avoidance (RVO, ORCA)
- Multi-agent navigation and crowd simulation
- Custom navigation mesh for non-standard geometry
Pathfinding Algorithm Guide
| Algorithm | Best For | Performance |
|---|---|---|
| A* | Single agents, grids | Fast |
| NavMesh | 3D open worlds | Very Fast |
| HPA* | Huge open worlds | Scalable |
| Flow fields | RTS, large crowds | Excellent for crowds |
FAQ: Navigation and Pathfinding
How do you handle dynamic obstacles (moving platforms, closing doors)?
Through runtime NavMesh updates, dynamic obstacle components, and local avoidance systems that react to environment changes in real time.
Can pathfinding work in procedurally generated levels?
Yes. We implement runtime NavMesh generation that rebuilds navigation data as procedural levels are generated.
How many agents can pathfind simultaneously?
With flow field pathfinding: thousands. With individual A*/NavMesh: 50–200 agents depending on hardware and update frequency.
How do you make NPC movement look natural, not robotic?
Through steering behaviors (seek, flee, wander, flocking), animation blending tied to velocity, and path smoothing algorithms that eliminate sharp turns.
Do you support 3D pathfinding (climbing, flying)?
Yes. We implement volumetric navigation graphs for flying units, climbing NPCs, and underwater movement in full 3D environments.
