3D Enemies With Pathfinding and Animations - Godot 4 FPS Tutorial 

For future viewers, if you notice that the auto-generated collisions for the skeleton don't stick to the model during animations it is addressed and fixed in the next video of this series! I'm talking about the collisions meant for bullet hits mentioned around 3:45

You can disable the movement in Mixamo itself, just check "in-place"

Dude these tutorials are extremely good. You need to make more!!!

This is really nice thank you, I found other tutorials on AI Navigation but they all used the default capsule and didn't include the looking at part which I wanted to figure out, thank you

Incredible, thanks it helps me a lot and actually stills working on godot 4.2

You're amazing, I was trying to figure this out for quite some time. Good video, keep up the good work, please :)

@LegionGames The look_at flipped problem can actually fixed by setting the third argument (use_model_front) to true. According to the manual: If use_model_front is true, the +Z axis (asset front) is treated as forward (implies +X is left) and points toward the target position. By default, the -Z axis (camera forward) is treated as forward (implies +X is right).

Nice one, you kind of forget to mention that you must enable looping in animation player in order for animations to actually loop.

If after you make the enemy look at you and suddenly he's rotating but not moving, its because of the path height offset, I set it back to 0 and now it works. The setting is in NavigationAgent3D > pathfinding

During the "Attack < Run" animation in the "Switch" and subtab "Switch Mode," if you're on Godot 4.2+, don't bother to use "at The End"; instead, use "Immediate" for this tutorial.

Hey, i'm not sure you know this but in 6:19 you could just export a node and use directly the same way you did there!

Nice! Looking forward to the next vids!

Absolutely brilliant tutorial, learnt some great code and ways to complete my game Thank you for sharing your knowledge.

2:50 press reimport I believe if anyone is stuck. Really hopes this helps. Let me know, its my first day in Godot

These are some of the best Godot tutorials that I've ever watched. Thanks alot.

hey this is a great tutorial! just curious if you could explain/make a short video on adding visibility range to them, like they only notice you when you get a certain distance away, im struggling to understand how to implement it :((

I really appreciate the tutorials you've been having, all of this has been incredibly invaluable. However, I'm having some issues with this one and wondering if I missed anything. I'm on Godot 4.2. After following the tutorial up to the creation of the zombie script, everything seems to work fine, but when I test the my level scene to see how the zombie works, it moves around the map at an incredibly fast speed and has is not focused on the player at all. The zombie simply zooms around the map in random directions at high speed before it finally just falls off the end and disappears Total loss as to what is going on

Not sure if it's a bug in Godot 4.2, but I couldn't rename my animations no matter what settings I pressed. I had to eventually go and re-name them inside Blender instead.

leaving a like to show my appreciation to the video, not because of how useful it was to me (it was) , but exclusively due to the fact he pronounces words with "L" as wittle baby would, which i find very cute.

this is perfectly what i need to do in my project. u sir came in clutch and saved the day!

I have subbed, because this isnt a copy and read, its an actual tutorial. Thanks alot, hopefullyi dont mess it up and blame it on the tutorial. And plus the get next path position has changed which makes previous tutorial sort of redundant

My zombie My zombie doesn't walk, can someone help me, I did everything said in the tutorial and it still didn't work, I tried other tutorials and it didn't work either, I'm starting to think that the problem is with the model or with the naviga agent

Thx ❤the first time a watch it I didn’t do it right so I try a different video an then I come back to this video and restart it and it worked and I know now what I had done wrong and great video ❤

around 8 min mark - the animation of him running starts but does not loop - even though I have active turned on

next video i recommend camera movement/reaction(camera shake). you know it shakes if moving right/left foward/backward(zoom in acording to speed) atacking/gettinghyrt(little shake in direction of atack, react to oposite direction of getting hurt) so many games forgot to add camera reaction when its something kinda simple and adds so much to immersion.

13:31 Hey bro, ah this part when we need to create this call method and the function hit doesn't appear. What can we do?

I don't know why yours works fine with your extra collision shape. For me the extra collision shape make it not work at all. Since I got an error for not having it, I added it back in but disabled it. It conflicts with the collision in the physical bones.

Beautiful Zombies!

My code is exactly the same as yours but my zombie keeps on flying off to a corner of the map, never to be seen again. And then when I added the rotation code, then he started flying circles around me at light speed. And I flipped his mesh around, just for the sake of doing it, now he flies off to a completely different corner of the map. I even disabled the nav mesh just to see what would happen and he still flies away. Now matter how low I make his speed, he's still to fast. I even copied in code from another enemy tracking tutorial that worked in a different project. Still just flies off in whatever direction. Is something wrong with my level? Edit: So I made a test level to see what it would do and it did the exact same thing. So I looked to my Zombie scene. It seems that it was the extra capsule collision shape added before the physical bones were made. I deleted it and now it rotates when I move but it doesn't go anywhere. So I'm going to put your code back and see if I can manage to make him move. Then I can finally move on with this tutorial lol I rewrote your code and it works. Not sure how it was different from mine though. Anyway, time to finish this! lol

7:24, my mob goes run off like as bullett. Why it does this? I have hatched 2 videos to solve this problem.

hey! I wanted to ask why would you prefer to use _process() instead of _physics_process() for the enemy? shouldn't collision based bodies be in _physics_process() most of the time?

Thank you so much for this tutorial, it really helped! By the way, any idea how to make the enemy not jiggle when it comes to the edge of the navigation region? For some reason it freaks out when touches the edges of this area, it always moves at the speed of light and just rotates back-forth

Thank you! Nice tutorial!

Yeah this is an Awesome video! I'd love it if you did some RTS style tutorials.

I like it, thanks for your tutorial!

THX BRO. You are te unique person that make good tutorials. I can't find tutorials like that in Spanish😭😭

can you please make a video on ranged enemies? I'm making a movement based fps so it is really easy to dodge the melee enemies shown here. ty

Very cool tutorial, thanks

I have a problem with the animation tree: When I switch the attack animation to "looping" the "at end"-transition from the attack state back to the run state is not working anymore. I guess this is expected, but it is important to have the attack animation looping, because when the player just stands still or stays in range of the player, the zombie should attack multiple times, so it should stay in the attack state. But I still want it to return to the run state once the player is out of range. I am guessing the "at end" transition never happens because a looping animation does not "end". How did you guys fix this?

So I'm stuck. when I try: "func target_in_range(): return global_position.direction_to(player.global_position) < attack_range" I get an invalid operands error: Invalid operands 'Vector3' and 'float' in operator '

Ty keep it up can you make a video that tells how to do world generation

Has anybody had issues running this in Godot 4.2.2 stable? I was having issues with the state machine not transitioning back to run, and so I downloaded the main project from github, it has the same issue. When they transition to the attack state they just stand still, and continue playing the attack animation.

I learned a lot! Thank you 🤓

When it try to add the enemy to the scene and run it it crashes and displays the text “invalid get index global transform on base null instance” how do I solve this

everytime i try to run my game it says “invalid get index global_transform (on base: null instance)” Any one know how to fix?

Well done, great video!

Neat well done - not sure if you did but using call deferred on hit and not calling it directly - my understand is this is performance - another small change is to use an area 3D on the player and on the enemy to control distance and link up the bools to the animation to area enter and area exist this can also have performance implications. distance_to is expensive to run every frame. Been enjoying this video

Hey man, this tutorial has been incredibly helpful to me. Can you offer any advice for making a range where the zombie doesn't pursue the player and instead idles/wanders? I tried but it didn't work, might be my misunderstanding of the animation tree.

in godot 4.1.3 when the attack animation is in loop we can't make the State_machine to go back to "Run" with "at_the_end" if we don't loop the "Attack" animation the enemy just hit you once and stand there how can i solve this problem ?

Thanks a lot for this tuto

dude you are a legend!

i would add a collision box to the zombie's hand and toggle the collider in the the animationplayer.

I have a question! For the game I am making, the enemies do not have animations. Can I still detect the damage, and how?

my attack animation doesn't loop. and if I change the animation to loop in the editor then it doesn't switch back to run. fixed it. change the "at end" to "immediate" on the attack to running anim

Anyone can please can help me that how did bro combined al the animations in blender in one as I am new in blender

Hi! I seem to be running into an issue with the AnimationTree Root Motion step, where setting the Root Motion track doesn't seem to lock it in place. I'm using the same mixamo animations as you but with a custom uploaded armature/mesh. Any ideas what could be the issue here? Thanks in advance. Edit: I just said screw it and redid the mixamo download with "in-place" checked

I'm so frustrated. I'm almost at the end of this tutorial. Things were rocky but I managed to get things to work for the most part. Except the zombie still floating above the ground when running but perfectly on the ground when attacking. And when attacking, won't do anything else until I get out of his attack range so he can run again. And on top of all of that, all the collision shapes somehow became catastrophically fucked. So I have to spend another hour placing them back where they go. I'm not having very good luck lol

incredible wow.

Hey uh, how do i make the enemies not travel in a straight line? i.e avoid obstacles and follow the actual walkable path to the player in debug mode for the nav agent, the path even shows that it wants to go around obstacles and ramps is there some other way to write the walking code here?

Thanks for the video. It helped me get a FPS player controller going. For the enemy's why don't you use a hit box (area3d/collisionbox) to determine if there attack works. The range approach seems kind of scetchy.

and why do I have a Zombie moving away from the player, and not towards him?

Hey! Great Tutorial! Sorry I'm late, but I have a bug. Sometimes, when my zombie finishes its stand up animation, it will fly up into the air really fast. While it looks really funny in the game, I don't want it to happen. Could you help?

Ty! Switching at end (attack) transition works if you disable attack animation loop from AnimationPlayer.

Great video and series! I just have a problem when copy and paste the zombie I get a debug error saying: Invalid get index 'global_position'(on base: 'null instance"). This error is occurring on the _target_in_range(): part, and _process part. I even tried to copy paste your code form the git hub, since I am relatively new in godot so I must have made a mistake, but I still get the same error message. How to fix please help??!!

i am struggling with a problem: the switch mode seems to not work properly in godot 4.2 i also found on reddit people talking about this exact problem, they used to have the same working pattern of this zombie regarding animations and also the way to switch between animation, but as they update up to 4.2 (they used 4.0 initially) this happens: the switch mode "at the end" seems to not work properly, so we get the zombie stucked in the same position with attack looping as soon he match the range condition, before that he runs fine towards player, but after that he just stares you blocked in the same position with attack loop

Why do you use process and not physics_process? I'm confused

1:45 having trouble with this part, maybe maximo or the import has changed im not sure but i cannot just click delete not sure how/what to merge

Thank you!

Doesn't godot 4.0 have a way to directly import blender files so you don't have to mess with glb files and stuff?

Thank you

very helpfull thank you so much

How can a distance parameter be established such that if a player is within one meter of a zombie, the zombie will start chasing, but if the player is farther away from the zombie, it will not chase?

cool game engine

possibility of a updated tutorial?

Can you make an AI tutorial with path finding

Any good alternatives to Mixamo? Makes me nervous relying on an Adobe resource.

for some reason when i followed until 7:00 everything was fine, but the move and slide function made my mesh just run into the void, had no way of changing where he went, was wondering if anyone has something similar happen to them?

Hi i have a problem with my animation tree: from run to attack it' s all right but I have noticed that the enemy character, does not continue to attack either if my player is still in range. the enemy remain stopped until I move my player. I have tried loop animation for the enemy smash but in that way, the animation tree remains always in the smash animation. Could someone help me to understand better the problem? thanks

Hi Legion Games, the Zombie just moves at a very high speed in the player's direction and falls off the map after i enter the script in the video, are there any reasons to why this is happening?

Everything is working but the collision shapes move out of place whenever the get up animation plays

Even though I'm using godot 3.5 , you saved my fucking life. I had been struggling with smooth rotation for ages. Thanks a lot. Btw, I actually rotated the enemy through code, and this created a conflict with lerp so I just ended up removing the line that rotated the enemy and used the approach showed in the video (rotating the mesh). With both lines of code, the enemy just kept changing rotation every frame

Can you please make a video on how to load another scene in this 3D Game (like accessible house or next levels)?? PS. Subbed :)

I keep getting the error "Invalid get index 'global_transform' (on base: 'null instance'). I don't know why this is. I did everything exactly as you did it in the tutorial

Whenever I try spawning them in, they spawn with no AI and are twice as big. How do you fix this?

For some reason there is an error for the code of the AI chasing the player. On the line "nav_agent.set_target_position(player.global_transform.origin)" it gives me an error. There are screenshots in the discord server for visual aid as I don't know how to explain it or even why something's wrong. Any help is appreciated :>

i have quarry , i made tps controller but it is not moveing in direction of camera faceing i can only go all direction (with animation) indipendent to camera can you help me i used same lerp logic and basic templet of charecter conreolled script

Hey Legion ! I'm doing a multiplayer game where the players are spawned, so i can't use player_path the same way you did, do you have any idea on how to solve this problem ? the players name aren't player1 and player2, they are 1 for the host and random numbers for the clients. thanks for the tutorial !

what shortcut button did you use to put the files inside the duplicates to the other file?

Hey thanks a lot for the tutorials. I am using a different model and tried to follown along in the code for the zombie but for some reason my zombie just runs instantly to the player and then starts spinning. I think that: velocity = (next_nav_point - global_transform.origin).normalized() * SPEED should normalize the speed etc. but shouldn't we be taking delta into consideration here? I am running on 144 hz

I am having trouble getting my movement to work. Here's the code: extends CharacterBody3D var player = null const SPEED = 4.0 @export var player_path : NodePath @onready var nav_agent = $NavigationAgent3D # Called when the node enters the scene tree for the first time. func _ready(): player = get_node(player_path) # Called every frame. 'delta' is the elapsed time since the previous frame. func _process(delta): velocity = Vector3.ZERO nav_agent.set_target_position(player.global_transform.origin) var next_nav_point = nav_agent.get_next_path_position() velocity = (next_nav_point - global_transform.origin).normalized() * SPEED move_and_slide() If you see any problems in the code, please tell me.

7:32 global_transform is invalid get index, null instance someone please help

If I wanted to have a more accurate damage model (e.g. heart, lungs, etc), could I place those within other collision shapes and check if the hit scan touches those to apply more damage?

For some reason, my enemy just runs off the map as soon as the game starts at a very fast speed.

Thanks for sharing. I'm interested in a similar solution, using a RigidBody for the zombie - there are still no such examples.

idk why my 3d model gets bigger lying down and t posing when i delete the duplicate

Weird... hitting x/del on 1:50 just deletes the rig on my end (blender 3.6.5)

Amazing tutorial on pathfinding but you are have not addressed one issue. All the enemies can overlap which means there is no distance between them and all of them are in the same position. Is there a possible solution to this problem?

2:50 it just doesn't work I'm working with 4.2

why when i play animation the Collision shape don't move with my zombie, like zombie moves with bones and bones collisions, but that one big circle just keep in one place when i play the animation.

Hey man, I finished the turorial but there is a problem. If you stand still, and the zombie attacks, the zombie freezes after attack finishes. Do you have an idea how to fix that?
