Active NavMeshAgent Avoidance - Run Away From or Around a Target | Unity Tutorial

AI pathfinding avoidance can be tricky. In this video you'll learn the basics of enhancing the built-in NavMeshAgent avoidance to have them walk around some targets or even run completely away from them!

Had to tear it up for my own use, but works pretty good. Not perfect, but really good.

[@Hazzel31337]

nice video gave me an idea for a game, i used your unity asset store referal link to buy rayfire, hope it helps as a little thanks

[@LlamAcademy]

Awesome! Thank you 🙏

[@vatyunga]

So it's possible to make a boids like avoidance on top of desiredVelocity? And it's probably possible to completely disable acceleration using agent.velocity = desiredVelocity.normalized * _speed?

[@LlamAcademy]

I think so. BOIDS on a NavMesh is something I’ve wanted to try out for some time now but just haven’t gotten around to it. For disabling acceleration, remember desired velocity accounts for slowdowns based on the baked in avoidance. If you wanted to just move quickly to the next point it may be easier to just get the direction to the next point on the path and set the speed to be speed * directionToNextPointOnPath

[@bokuwa_Tobi_0210]

Bro I have got an issue. I have created an ai script which wander along random wander points over the navmesh. However, sometimes the wander points are invalid and the ai does not move to the wander point and remains stationary at his position unless I manually move it to the wander point's position from the scene view. I would be very glad if you can help me...

[@LlamAcademy]

When picking a wander location you can call NavMesh.CalculatePath and see if the status is "Complete" (or check the Agent's path). If it is "Partial" that means the agent cannot fully travel to that location

[@silchasruin4487]

Who ME? Haha, I've been kicking myself trying to figure out a more performant way to use pathfinding to avoid the jostling and overlapping of Unitys navmesh agents. I'm trying to see if I can't figure out a way to implement RVO2 type of avoidance and collision detection while piggybacking off of Unitys default NavMesh Component.

[@LlamAcademy]

Doing a custom RVO2 agent is something I've wanted to do for a long time but haven't gotten to. If you figure it out I'd love to see it 🙂

[@LlamAcademy]

Oh, and YES YOU 🫵!

[@ahmedmalik2856]

Your tutorial is Amazing, EVERY ON IS!!! Great Work and keep it up man! Suggestion : There seems to be background music but it's volume is very low. Your voice was overpowering it. I like tutorials with interesting music and maybe more sounds when you say something important or stuff. That way it will be more engaging like look at Dani or Thomas Brush. Cheers,

[@LlamAcademy]

Thank you for the encouragement and feedback. In the earlier videos I had the music too loud so maybe I went a little far in the other direction to make it slightly too quiet now.

[@ahmedmalik2856]

It is zoomed 300%. If I pull it up on mobile and don’t go full screen I can see it’s a little small though. Maybe I’ll go a little bit more in the future
