How to Animate Characters in Unity 3D | Blend Trees Explained: One Dimensional

[@ivyzheng2047]

The series so far is the most explicit Unity tutorials for me to follow along so far! You're my LIFESAVER! Thank you so much Nicky! Can't wait to see the rest of them!!!

[@NoldoWalker]

Agree, best about animations what ive founded for now!

[@CJRH1FILMS]

I'm diggin your music choice. Somehow it keeps me even more engaged, like I'm solving a puzzle in a videogame or something

[@kitchenspider1539]

Agreed... the music really gets the noggin' joggin'. weird but true

[@fret2fret221]

you've gained a sub man. holy crap. im actually starting to understand code and how it works. it all looks like gibberish before this particular video. now im starting to realize what it all means in the script and how its logically written. so fascinating. thank you! I don't know if its planned in your series or not but I would love to see a video on world interaction. specifically walking toward an object and picking it up, climbing onto something, etc. thank you.

[@GameDevNerd]

Code is the best part! It's just a way to tell a computer what it must do and how to follow your commands. And it's not hard at all, it just looks intimidating at first, but it's all simple, short-handed ways of expressing logical processes and the flow of control. Once you get familiar with coding and learn a language you realize you can literally make anything you want happen in a computer system. :-)

[@kentrose2520]

Love how you explain every field in the animations, blend trees, etc. Really helpful!

[@iHeartGameDev]

Thanks so much Kent! -Nicky

[@MarkRiverbank]

These are extremely helpful for learning more complex animation. A couple code tips though, it's generally better to expose your fields in the inspector by adding the "[SerializeField]" attribute rather than making them public. And, for your input handlers, there is the class "KeyCode" with static members for all the keycodes, so you don't have to use strings (eg. KeyCode.W, KeyCode.LeftShift).

[@gaetanolombardo6150]

I have never listened to a clearer and more proper explanation on mechanim than this one. At last. This is gold

[@038alpha]

You know he's a good teacher when you manage to solve your own issues just with what he told you. There was somthing wrong in my blending, arround 0.5 velocity it seemed like the feet and legs were barely moving, the animation was odd. So I thought maybe one animation wants left foot forward when the otherone wants right ! Just added 0.5 offset to running and boom, done. Only because you clearly explained what is blending and what is offset. Seriously, congrats, i'm exited to see other videos, i'll recommend your chanel to anyone interested in video game dev. You're the first ever content creator i'll actually click the bell for haha. Thx for your work.

[@chief_rasko]

Nicky, while following the tutorial I found that when setting up the initial transition back from the first Blend Tree to the Idle animation, setting the Condition for the transition as Velocity < 0.05 caused the Animation to jitter/revert back to the Idle animation for a second before continuing with the walking -> running animations, this was quite confusing however setting the Condition for the transition to Velocity < 0.01 instead fixed the issue. Hope this helps anyone who came across the same issue

[@RaulCesarAdolfo]

This helped me, thank you :)

OMG that bugged me out thanks mate appreciate it

[@Northwise]

Needed a short introduction to implementing locomotion/blend trees in my game. Every video was unneccessarily long and didn't give info straightforward. You gave me what I needed in literal seconds by your timestamps and straight forward explanations. Couldn't have been done better - thank you!

[@digital_comrade]

I am new to Unity and this series is amazing. Not only is it great for teaching the concepts of animation in unity, you also do an excellent job of teaching programming basics for those that might not have them. Thank you for your amazing work!

[@tb__66]

Keep up the good work. So far your videos have been the most helpful in understanding not just "do this and this will happen" but WHY it happens, which is infinitely more instructive in learning how to use Unity beyond the limited scope of a tutorial.

[@iHeartGameDev]

thanks very much!

[@eliebeaino]

only 1k subs? I randomly discovered you, your videos are so high quality and cover topics in full detail and are quite systematic. I'm familiar with most of the animation system but what make you stand out from everyone else is that you cover the little nitpick details even if you aren't using them in your guide and this is what I've been looking for awhile. I've taken multiple unity courses and you are the only one covering what needs to be covered. thank you.

[@jas2890]

for thos who want to still use the run with shift feature still ive pulled some messy code up for you: using System.Collections; using System.Collections.Generic; using UnityEngine; public class AnimationStateController : MonoBehaviour { Animator animator; float velocity = .0f; public float acceleration = .4f; public float deceleration = .8f; int velocityHash; public float MaxWalkingSpeed = .5f; void Start() { animator = GetComponent(); velocityHash = Animator.StringToHash("Velocity"); } void Update() { bool forwardPressed = Input.GetKey("w"); bool runPressed = Input.GetKey("left shift"); if (forwardPressed && velocity < MaxWalkingSpeed){ velocity += Time.deltaTime * acceleration; }if (runPressed && forwardPressed && velocity < 1.0f){ velocity += Time.deltaTime * acceleration; } if (!forwardPressed && velocity > .0f){ velocity -= Time.deltaTime * deceleration; }if ((!forwardPressed || !runPressed) && velocity > MaxWalkingSpeed){ velocity -= Time.deltaTime * deceleration; } if (!forwardPressed && velocity < .0f){velocity = .0f;} animator.SetFloat(velocityHash, velocity); } } ps. the variables are changed to suit my game.

[@blaccy5991]

Don't put every line of code into update. Put them into their own separate functions and call them. Also you are creating new bools every frame instead of holding them as a private variable. A better way would be to make a function to get inputs (isCrouching, isSprinting, isWalking etc) another function for setting your velocity velocity and a third function for setting your animator variables. If you do this it would be more modular, more performant and much easier to manage.

Thanks so much! Happy it helped!

[@GameDevNerd]

I liked and even went ahead and subscribed. I'm an old DirectX programmer and C# master who just started messing with Unity and your videos solved confusion I had about getting animations working and taught me what all the editor buttons and gizmos do. I'm doing my first Unity game prototype right now and it's getting quite sophisticated. I've done all of these things before, and used to write my own engines on top of DirectX and OpenGL, but Unity is a new tool for me. So far, thanks in part to these videos, Unity has been an absolute joy to work with. I was away from development for a few years and the industry and tech has advanced GREATLY! There's never been a more fun or interesting time to be a game developer than today in 2021!

You can also just clamp velocity if (forwardPressed) { m_Velocity += m_Acceleration * Time.deltaTime; } else { m_Velocity -= m_Deceleration * Time.deltaTime; } m_Velocity = Mathf.Clamp01(m_Velocity);

[@nathanielscheurer1821]

I absolutely love your videos, they are straightforward, in-depth but also simple. One thing you could improve however is to take a second or two to pause when you finish a script so the viewer can look through it.

[@thygrrr]

Excellently structured for intermediate and advanced unity users. Awesome tutorial!

[@SassyPantsy]

Amazing tutorials man, Subbed! For anybody having trouble with jittering in the animation - basically a split second transition between the blend tree and back to idle, and then back to blend tree again: The reason this happens is that for a split second, by using an acceleration rate of 0.1f, the value of velocity is both less then 0.5f AND greater than 0, so the animation does this double transition. To fix this, Up your acceleration values to something greater (for me it's 0.5). It might be effective to do a much smaller number, but I couldn't find one.

[@nikesh_niki]

I did 0.5 but still facing the same issue. Any idea why ?

Hey Nicky. Mine was waiting to finish idle animation then transist to a walking anim. So I needed to wait second to get it walking. Did I miss something. So what I did was like in the previous video, disable "Has Exit Time". And it started walking instantly. But then came a another problem. The moment I press "w" it is looping 1 time (walking to idle), just the first second. So only the first second it is accepting the walking to idle, and then continues the normal walking, a split second of a glitch like. I solved that problem by setting the transition from ( walking to idle ) velocity 0.05 to 0.01, then it worked. 02:00 Has Exit Time was not deactivated in the video & the 0.05 that I changed to 0.01 for the hikup.

[@venomtoxin]

@@iHeartGameDev That helped yes.So I can do it my way... velocity from 0.05 to 0.01. or acceleration from 0.1 to 0.5 helped for example. I still dont know what the problem is accually. Code is the same, just the animations are a little different, can that be the problem. I can not find the exact same animation you chosen offcourse.. you search on mixamo walking you find 30 with the same name. maybe the problem your animation takes less frames, or timeframe whatever... And that makes a differents maybe. I dont know. Im the one that is here for learning animations :D haha. Im waiting for the next episode. A locomotion would be awesome. I backup your project, so we can continue again. I made a copy and tested with the asset FinalIk. Have a nice day, my bell icon is on.

I was not able to get this working, as of 3/10/22 and using Unity 2020.3.25f1. I have enjoyed the previous videos but there are a lot of inconsistency with this one; 1. When creating a new Blend Tree Unity automatically creates a float parameter called Blend and connects it to the Blend Tree. At :58 you can see this in the parameter list. When you return at 1:34 that parameter has been deleted without mentioning it. Later at 2:23 you state that the Blend Tree defaults to the Velocity parameter, but this is not the case. Mine is still defaulted to the "Blend" parameter, even though I've already deleted that parameter it to be in sync with what you're showing. Finally, if I hit play and attempt to slide the Velocity slider shown in the Blend Tree graphical editor it does nothing. If however I alter the velocity in the Parameter list window...that will affect the running animation.
