NavMeshLink in Unity - Adding Jumping to NavMeshAgents | AI Series Part 2 | Unity Tutorial

In this tutorial I go over what a NavMeshLink is, how to add it to your NavMesh, and how to make your NavMeshAgents look a little nicer when traversing a NavMeshLink. The NavMeshLink is how you can make your AI jump between two navmeshes, jump over an obstacle, or even jump up onto a platform.

NavMeshLink is the higher level component that correlates to the built-in navigation system's OffMeshLink. The Navigation system understands an OffMeshLink, but in the editor you'll add NavMeshLinks to define where those OffMeshLinks should be added.

I recently finished your scriptable guns series and it helped me a lot in a project. Now I'm going to start with this AI series. Thanks for making this kind of content.

[tomoliverharrison]

This channel deserves way more subs and views! Great tutorial and looking forward to getting through the whole series

[AlexisBleeding]

I think the AI is the most difficult part of making an video-game for me, and this channel saves my life. I thank you a lot, u are amazing.

[placebo_yue]

the tip about the curve script was crucial! It makes an enormous difference. thank you

[maitrykotak]

following this channnel from.a long time, , , , its just very helpful

[NunSuperior]

I always wondered how off mesh links worked. Now I have them working. Awesome.

[DaviSouzaGamer]

The animation curve was resetting its value to an empty curve whenever the object was deselected. Removing the "m" prefix from the "m_Curve" field solved the problem for some reason.

[munyunu]

So so so useful and well-explained. Thanks so much.

[lukasvolcik]

Omg thankssss! ❤ exactly what I was looking for ❤ you're a lifesaver, I'm trying to build RTS where you can walk with your character inside of a newly built building.

[locusruizlopez]

I didnt know anything about nan mesh link, thanks :)

[rasheedqe]

Great video that jumping component really helped.

[alextrollip]

It might be useful to in the intro show what we'd have at the end of the video.

But it's pretty useful step by step guide so far.
I've been reading through he documentation but videos are always less energy intensive to follow along with.

[ayuguplays]

simply great video

thanks for the tutorial. keep it up

[CrazyBabirussa]

After setting up Curve, it doesn't save the value. Please help.

Is there a way to activate/disactivate a NavMeshLink when we need? right now the solution for me is to use a NavMeshObstacle to block either start point of end point.

[refinedturnip]

Quick question regarding the RaycastNonAlloc.

It seems to be way less accurate than the standard Raycast. For instance clicking on the top of the walls with the navmesh jump link, the ray is ignoring the wall and hitting the ground behind it sending my agent walking around the wall, wheras Raycast always hit the correct object and the agent jumps onto the wall.

Could well be missing something really obvious as I'm fairly new

Loving the series

[ty-xqbl]

for procedural generated games involving navmeshes how would you implement a way to add these navmesh links? Would you just piece each prefab with a meshlink or do something more code driven which adds the mesh link params via code?

[ChadGatling]

I can't get this to work. It's just doing nothing. I have 2 objects with nave meshes and an object with a link and the ends are on the different meshes but the connecting lines are dull and agents ignore the other nav mesh.

Edit: Got it. The little circles indicating that the link was on the mesh were very small and I was not noticing that they were not activated.

[koolbro]

When using the AgentLinkMover, my agent jumps across to the end point, then jumps back and then teleports back to the start, any thoughts on how to fix this?

[candycodes]

Another nice tutorial. :D

Keep it up man! I 'm just following along :D

Although I think AgentLinkMover is a bit buggy right now. It no longer works if I disable then enable my object(any object the component is attached - player or enemy). So I opted not to use it.
