Creating your first animated AI Character! [AI #01]

This is the first video of a brand new AI series! Animations are added to the NavMeshAgent by feeding the velocity of the agent as an animation parameter into a blend tree. Following the player is achieved by setting the agent's destination to match the player's position. Enjoy!

Wow. Today I learned I can wield the gizmo magic. I feel like Zeus!

[@CosmicComputer]

this was brilliant, I learned so much about navigation that I just didn't comprehend before, thank you!

[@adeveloper7184]

Ok so third person shooter and this together gonna do wonders. Make all the AI freaking genius ;)

[@henrikekholm6437]

I've followed a lot of tutorials and ended up asking what went wrong in my childhood.. but this was just so much fun! thanks, great work!

[@TheKiwiCoder]

You are not alone 😂

[@gorrillaconvention]

A note for anyone else that may have this problem. If the NavMesh won't bake. Make sure you have your meshes set to static.

[@MsChemicalRebel]

Thank you! Just started and there was already a problem eheh

[@gorrillaconvention]

@@MsChemicalRebel Happy it helped!

[@drseed2828]

Thanks, just had to put a checkmark under Object, Navigation Static, and chose to include all of the children, and that worked, for me, using the HVR platform.

[@gorrillaconvention]

@@drseed2828 Awesome!

We're currently making a game and this was very helpful! moving on to the rest of the series as we'll need pretty much everything you're covering!

[@drnow3621]

Thanks for this new series. Easy to understand and clear as usual. It would have been nice if you enlarged the code text slightly. It is difficult to read, especially on my iPad.

[@TheKiwiCoder]

Yes apologies for that, will make sure to do that for the next videos!!

[@eliburwell3109]

Your amazing man i just needed to know how to move my npcs and creatures and i could not find specfically the problem i was having you have solved a massive barrier for me.

[@diliupg]

This video is fantastic! It would have been fantabulous if you incorporated enemy avoid player if player ran towards the enemy too. But as it is it is the best on the subject matter so far! (Still not too late to incorporate that in a later video.. :) )

Great video man - On my way to the next one :) Just a question, if a want a character to run to a door and then i opens automatic, how can i set the door to baked, so the AI knows it can run towards the door and the through it went it opens? - Long question i know :D Hope you can explain or point me to a place to read up on it :)

[@drseed2828]

Hello, I had success, using the Navigation Mesh Agent, but my animated characters do not move, after applying the Locomotion Script. The animation (AiAgent) does follow my 'Player' but doesn't walk, run sprint or move in an idle manner. I used custom animation characters, in which I added the rig, using Mixamo. I also used one skinned character, to apply skin to the rest of my animations, based on the same character. Any ideas on how to get my Mixamo characters to animate would be appreciated.

[@drseed2828]

To kind of answer my own question: I used the Mixamo animations by not using 'blend tree', and instead used a bunch of transitions, and used different Speed values, to navigate between the animations. I also have the Mixamo animation 'checked' to loop and unchecked 'has exit time' on the animations that need to stop, and change to another one, abruptly. I also unchecked 'apply root motion' in the AI agent character. I'm sure there is a better way, this is more of a workaround.

[@CarpathianWasteGroup]

Hey! Is this the player from your Unity Third Person Shooter - Using Animation Rigging series?

[@ethanwebb2035]

I think I am doing something wrong, in the blend tree the speed parameter isn't changing when the AI moves which means that the animations do not change from idle, I then get an error message that says "NullReferenceException: object reference not set to an instance of object" can anyone help? Never mind I fixed it I accidentally put a dot instead of an equals when identifying the animator. Thanks for the great vids they are really helpful for my college project where I am making a melee combat fighting game.

[@romanbaranov1984]

Thanks for the tutorial! I'm watching this on 12.2021. I have a problem with very slow NawMeshAgent rotation and movement when I push the "Play" button. Solved it by putting agent.destination = player.transform.position out of Unity Update() and put it inside Start(). I think the Unity team updated this functionality.

[@JSHStudios]

Great tutorial can you provide the project on github?

hey im new to unity. How do you run the game like you did here but from an observers point of view when you were testing the path calculating and gizmos? also my path tracking line or anything really doesnt show up from the debug script when im running my game :(

[@TheKiwiCoder]

The game view will launch automatically, but you can switch back to the scene view to fly around. Also you can disable that behaviour kinda by right clicking the play icon

[@talalbow]

i tried literally everything and the navmesh agent just wouldnt move at all turns out the problem was obstacle avoidance 🤦‍♂️ just turn it off completely like in the video haha

Hi, I followed exactly your steps and used the same codes. Yet right now my NPC animation does not change when its speed changes. For example, when it collides with the player and stop moving it still plays the running animation and won't change into idel as you showed in the video. Please help!

what are these 3d models i want them pls

[@Lopeanti]

its not working anymore?

[@JackaldudeVR]

Very good tutorial but I’m having an issue where my agent won’t follow my player prefab. It’ll follow the player if I drag over the player straight from my scene but it won’t if I drag the player from my prefab folder. I even deleted the original player prefab and save my scene player as the new player prefab and it still won’t follow. It also won’t let me save the agent as a prefab if I currently have the scene player selected as the transform target. I know that was a lot but any help would be great lol

[@TheKiwiCoder]

The player must be assigned from the scene, not the prefab itself.

[@JackaldudeVR]
