NEW Procedural Animation In Godot 4.0

[@psaldorn69]

Very informative, thank you. If anyone is following this using c# you may want to know. `Basis = Basis.Slerp(endBasis.Orthonormalized(), speed * (float)delta).Orthonormalized();` and `Position = Position.Lerp(Position + Basis.Y * heightDiff, speed * (float)delta);`

[@mikailcf]

Man, your tutorials are on another level. You cover some advanced stuff that can add such polish to projects, and all explained in a simple way. Eager to see what comes next from you.

[@ChrisD__]

2:38 I love how everything just stops, everything goes silent, and the the little robot just does a little dance. :3

[@TranquilMarmot]

Heads up that SkeletonIK3D is marked as deprecated and will be replaced with something else in the future! Just letting you know so you can look forward to redoing this tutorial again 😂

[@mr.hashundredsofprivatepla3711]

[@GeekzAnonymous]

Any news on why SkeletonIK3D is current marked as Deprecated?

Take this with a grain of salt, but I’ve heard that SkeletonIK3D is gonna be replaced with something new soon.

@@mr.hashundredsofprivatepla3711do you know if its been replaced yet? Or if theres been any more news on this?

[@Geskawary234]

@@andguy probably in godot 4.4-4.5. Hopefully it will make animation like this easier

[@fatsumo]

kinda wild they just remove stuff without adding a replacement for the feature removed- i'm not even working in 3d, but things like making a pixel perfect smoothed camera, several tilemap features... they just.. poof! and haven't been in the engine for like a year+

[@industrialdonut7681]

Thank you for this gold, I invested many hours trying to do something like this on a humanoid previously and ultimately did not really get the result I wanted. You've inspired me to try again, and I really think that your method of using tweens to get the halfway stepping-over effect makes it WAY simpler to do what I need to do now...

[@Gredran]

You’re amazing! Thanks for all your videos! This one’s gonna be super fun! I’m definitely gonna be going further with this base and messing around with different walking things and see what I can do with this 😁

[@crigz]

Keep me posted on how you get on!

[@Gredran]

@@crigz for sure! May be a little bit but I was probably gonna experiment with a mixamo rig, and my own basic character rigs, to see if I can get them going. Well maybe not mixamo, but maybe I’ll give it a try just for the people who are aren’t too great and rigging, it would just need IKs added in since the mixamo rigs don’t come with them 🤔 But I know you know how much time it can take lmao. I’ll let you know if I need a few pointers if I get stuck haha But I’ll see what I can do and maybe post it for others and credit you of course! I’ll say I used your system as a base and hopefully explain how to apply it to other humanoid characters 😊

[@qevnine8923]

fella your channel is a real treasure

[@thegamedevclub]

Really cool video! Just a little annotation for those who could get problems using this for their projects: if you set turn_speed too high you might get problems as temporarily the position of the adjacent legs switches -> the points for calculating the planes are not in clockwise order anymore -> normal is pointing into the ground -> weird behaviour. So keep this in mind ;)

[@lethn2929]

The quality of Godot 4 tutorial videos coming out has been fantastic along with all of the mechanics we can make and play with now, thanks for this! Been wondering about Godot's compatability for procedural animation.

[@NihongoWakannai]

at 3:22 the rays are children of the targets, at 3:33 suddenly the targets are children of the rays 6:15 this script is frame-rate dependent, and since i had vsync off with 1200 FPS it was not working well at all

[@Sethbeastalan]

For the frame rate dependent issue, replace vector with vector.normalized(). This means you have to change the magnitude of the offset to compensate, I find 1.5 works pretty well. You'll probably get a "Basis must be normalized" error if you do this. If so, the solution for that error is explained in issue #3 on the github repository.

[@lukky.]

Love seeing your editing and gamedev skills improve every video :) great stuff !

[@nikolastanojevic6082]

In 4.3 works like a charm. Thank you.

[@JorgeRosa]

This is something really impressive! - Well done, Crigz! 👍

[@EngineerNick]

Omg so cool thanks for the video :) If you do another one you gotta put some springyness in the body height calculation to give it some bounce :)

[@crigz]

Yeah I think just adding a multiplier to the distance in the height offset calculation and reducing the lerp speed could make the effect more pronounced. Or even forgoing the lerp and using a tween with a bounce easing could work. Something I'll play about with when I come to use this in a game.

[@darknetworld]

Wow that a lot work and coding. Great work on improving on the spider. I did work on base on old video that found and had to look for refs videos. I wonder if the cat or dog workable for this? But guessing the sit and walk target and magnet will be effected or change position.

[@crigz]

It should work, you'd probably have to tweak the magnets as you said, and also play about with the tweening of the IKTarget's more to get the walking to feel more natural.

[@tangypop]

Thanks for explaining how to use the IK classes in Godot. I've used the SkeletonIK3D class for leg and arm animations while driving (steering wheel, pedals, gear shifter animations). It might just be my computer, has an older CPU and GPU is GTX 1080, but the performance of IK in Godot seems not great. I'm using the chains just to position the legs and arms, so the hand and foot rotation are excluded and are still manually rotated. Leg chains have 3 bones and arms have 4 (shoulder to wrist placement basically). I even have it set to 1 for max iterations. I put a toggle in my game settings menu to turn on/off IK and while off gets 60FPS (I have max FPS to 60) and while on drops to ~40FPS. Other than the performance hit the animations look believable with the appropriate magnet values. But for me I might have to go back to manual positions/rotations of bones for animations. The only thing I can think of is the chains have too many bones, but 3 or 4 don't seem unreasonable. And the scale of my model in game is 0.01 so maybe there's some weird math going on but I'd hope the IK algo doesn't increment by a set small amount while finding the solutions. Anyone else have such a big performance hit with the IK stuff in Godot?

[@Algardraug]

This channel is a gold mine, keep it up! Will check out twitch as well!

[@RaveYoda]

Absolute Godsend as I'm on 4.0.2 and didn't see settings mentioned in the prior video you had done.

[@theyellowarchitect4504]

Enemies which climb on walls instead of fighting on the same ground level as you, are fun because they are so unique. Especially if you play as such an entity! Thank you for this video.

[@gooficat]

tip: you don't have to rotate the raycasts to the right angle: you can just move them up and inward then, change their targets to down and outward

[@jakepeters4337]

Exactly the kind of tutorials I'm looking for, thanks!

For people that can't seem to get the SkeletonIK3D to work in editor but work in game - with SkeletonIK3D there's Play IK option on top of the editor, you need to have that checked if you want to see updates in the editor. I don't know why it was disabled for me by default.

[@dmas7749]

protip; you can edit multiple values by selecting multiple nodes as long as they're the same type, no need to set up each offset individually

Cool video! Do you have in mind to make a tutorial about dismemberment function with procedural animations? Like, of you shoot the leg of the spider character It Will loose his leg and the animation Will change (and also the movement system)

[@shippous]

I guess you could change the target's position dynamically to compensate the leg that was taken. Like it's trying to balnace itself somehow.

[@gamedev4032]

Really cool, thank you for the tutorial!

[@LMNT-Kitchen]

That's a great tutorial! I am new to Godot and i got a question: Is there a reason why you just used a Node3D and not a CharacterBody3D or RigidBody3D? And, would you use them if the Robot should interact with the World a little more?

[@crigz]

Welcome to Godot! The reason I went with Node3D was just to keep things a bit simpler for the video. You could absolutely use CharacterBody3D or RigidBody3D to add physics interactions.

Heya! A bit late, don't even know if this'll be seen, but does anyone know how to make this work with navigation? I'm working on a small game and want to use the movement this video shows us to make, but i want to make it an automatic enemy, not controlled by the player, can anyone help out?

[@paigepolaris1799]

Did you end up finding a solution to this? From what I'm understanding, Godot won't bake walls and ceilings (you can maybe get them by changing the 'UP' direction in the project settings, but then you can't bake the ground), so I've been using imported navmeshes. I can get it to move up walls, but only when the entire navmesh is one 'island'... It won't go across multiple NavigationRegion3D nodes without NavigationLink3D nodes placed all over the place (which gets messy if your level isn't all one mesh) or with 'Edge Connections' when the 'NagivationServer3D is active,' which I can't wrap my head around since there's so few tutorials about it.

Are there any project settings involved to get the IK skeleton working? If I import your project, the spider works without issue, but when I apply the same method to my characters skeleton, it's unresponsive to moving the marker.

[@hom7998]

I had the same issue in 4.1, I tried following along on my own model but whenever I spawn him in his legs just go to where he started

[@RSSpeacemaker]

Hello! Firstly thank you so much for this tutorial! This overview was fantastic! I've implemented your workflow into my project and noticed that the performance, while normally quite good in any other circumstance, really tanks when having multiple entities with the same duplicate procedural animation. Have you by any chance found a fix for this?

[@orwinsen4510]

where did you fins this sky texture ist amazing

[@panagosu]

I am trying to now combine this logic with CharacterBody nodes by having my root node be a CharacterBody3D node instead of a generic Node3D. I also went ahead and put collision shapes for every bone. My problem is the leg collision shapes mess with the inverse kinematics, leading to unnatural solutions to the IK solver. Anyone on the same boat?

[@thfrussia6717]

Cool but if we extend this to the reality the spider still needs to be affected by the gravity. Even if it can climb walls. It will not be like his legs adapt to his movement but his legs support and cause his movement which is absolutely different.

[@VixenteEs]

Nice tutorial, very detailed. Thank you. 👌

[@mirtir472]

would it be possible to make something like that for a biped (human) i would like to have that kind of movement to a human character

[@rredenvous]

Hell, i tried to do the same you did but like nothing worked ok. It's a sign to learn more :(

[@adamthefirst401]

Cool but legs keep getting stuck behind, pulling down the spider. I guess the movement of the spider is to fast for the legs to hit their target in time to let the other legs _step but I don't want to increase the legs movement speed. Is there an way to fix this?

[@PhosphoCat]

Quite late, but do you think you'll make a 4.3 version? There's quite a few issues that arise when using 4.3 even if you try it out on your own tutorial project that you provided but I have a feeling you'd rather wait until the SkeletonIK3D node gets updated to make another updated tutorial.

[@Mrtargi]

Cool! I've copied all your realisation, but my bot is usually go through textures, I've uploaded your coded and there are the same problem. I'm using godot 4.2.1 for now😮

[@samuraikina5908]

Nicely done 🤙

[@coloneljcd6041]

Good stuff!

[@randomd00d19]

Are there anyways of doing this without raycasting 1 time per leg? If I wanted a few dozen of these little guys running around my scene, it would tank performance.

[@SamuTheFrog]

Not really. Any other options I can think of would be just as bad if not worse for performance. I'd say this is one of the better ways to go. Perhaps you can set up occlusion & screen space detection so the anims/raycasts disable when not seen, otherwise, I got nothin.

[@mch43856]

Amazing tutorial!!!

[@Duodecimus-gz5fw]

Would you have any advice on how to deal with walking off an edge? I.E. the bot walks to the edge of a large cube with a 90 degree angle cliff. As is the code can't deal with that, the raycasts stop triggering step updates, the feet bunch up and things get weird as the planes turn into lines. I'm currently thinking that I add a dummy target to the end of the raycast below the bot, and use that target if nothing is actually hit. assuming it isn't too far away, it should cause the main body to pivot enough to find the actual ground again.

[@danielgrizzlus3950]

I am interested in procedural animation of models on runtime, with various skeleton morphologies. I am wondering if this can be applicable to it? Can I translate this approach to a generated mesh with a skeleton on runtime, and will it look natural regardless of positions and number of limbs?

[@pour_understanding]

Trying to follow along in 4.1 but the SkeletonIK3d is very broken already. :( Interestingly, the bot in your git repo is playable ~ until I inspect any of the leg components. They break immediately without me even moving them.

[@_ByteBlaze_]

4.2 does a decent job with IK. You have to add your IK to within the Skeleton3D, and make sure editable children is on. Also, one change that everyone should make which isn't outlined in the tutorial is that the Raycast3D should go onto another local node, and use the other local node that the tutorial puts it under as your reference node for the global. So basically, do it exactly as it is via the scripts and reference assignment, but when you do your hierarchy, don't put the Raycast under that local feet (put it under another dedicated object that sits in the same position) because otherwise what happens is if you go off an edge, like off the map or jumping, etc, the raycast will get stuck at the last spot it was able to connect with, and you won't be able to get it back to its original spot easily. With my proposed change, you can distance check the two local nodes, and if they are too far away, you can teleport it back to where it should be, and that will keep the system functional when there is no ground under you

[@imranbm]

Talking about animations, is it possible to implement a similar animating style to mw 2019 inside of Godot?
