If you are reading this, say hi :]
Thank you for watching!
Watched the whole series and it is really well explained!
Probably one of the best unity tutorials and always straight on point.
Subscribed =)
i guess I'm kind of off topic but does anyone know of a good website to watch new movies online?
@Kenzo Misael definitely, have been using Flixzone for since april myself :D
@Kenzo Misael Thank you, I went there and it seems like a nice service =) I appreciate it !
@Ashton Quincy you are welcome =)
Completely agree
The fact you timestamped every little piece of this video shows next-level dedication to making the information accessible.
Thank you Kulak! Happy to hear it’s worth the time investment!
If making tutorials is something you enjoy, I beg you to keep going. You have the 'x' factor for it (i.e. voice, cadence, attention to detail, etc.)--see the rate of people saying likewise in the other comments. This series is exceptionally done. For me, the main detail that I have enjoyed is how you explain EVERY menu-item found in the unity UI when covering the topic. It is extremely common to see tutorials that: only cover a very primitive overview of what they are implementing, never explain how their 'solution' scales to other implementations, never touch on the details of other features, never explain why you would use their idea (vs. some other concept), etc.
Based on that, I think it is essentially guaranteed that you can grow your channel to an arbitrary amount of subscribers/likes/views. I would not be surprised to check back later and see you have 100k+ subs.
Best of luck, and again, well done.
If you're having trouble making the animations blend and play correctly make sure you have the animations looped as he explained in previous videos. He didn't explain it this time and I had trouble figuring out what I was doing wrong.
I had the animations looped but my character waits to walk then it blends after that wait
Comments section is a lifesaver sometimes lol, thnx fam!
@@rwinftw disable exit time
Thanks you're really awesome
Great series! Getting to understand a few things I had doubts about regarding the 2D Blendtrees definitions! Love the pace on this last ones as well. Loving that you're taking the time to work some refactoring at the end while keeping the main development as simple as possible! Just great job! 🎇😎
Dude this is one of the best tutorials I've ever seen I've been looking for something like this for so long. Thank you for this so much
Great tutorial! I love how well separated and organized it is, on the video player and on the side bar.
Outstanding quality! Instant sub. I like how much effort you put into the explanation! And even timecodes, wow. Please keep making Unity tutorials like these :)
Here you are almost a year later and your videos are still helping aspiring game devs learn essential concepts to create. Thanks for what you do man!
I love the fact that you cover almost every aspect of Unity's UI which helps to learn more about the topic and develop better game. Nice background music, this is how all tutorials on the internet should be.
Honestly, a really well done tutorial series that gets me excited to learn more! You're doing great!
Bruh, I've been looking for a tutorial series that actually explains what's happening and not just how to accomplish something! Great job!
I didnt even notice there was an ad at the beginning of the video because you make us so excited to see the tutorial asap. Wonderful work!
Great explanation of this complex mechanics, thank you so much for your work!
I didn't even know how to approach the animation process before, but now I will definitely try!
You are absolutely the king of Unity animation tutorials, these go so in-depth and are explained really well. I'm glad I found this!
Honestly, after 7 months of learning gameDev by myself, finding your channel is like taking a breath of much needed air. Everything's explained instead of just being written down, including the glitches, so we could learn what makes them happen, and what should be taken into consideration. Way better tutorials than everyone else, including brackey's and the other big names. I sincerely hope you continue with this!
Really amazing tutorials you have! Clear and easy to follow, very well planned! Would love to see a similar tutorial for creating NPC character animations :)
You have a natural gift for teaching and breaking thing's down to bite size chucks. Great work on all your video's. Thanks for making them available for everyone to watch.
I think this was an amazing video because you not only showed HOW to do something; but, you explained the WHY behind everything that was done. Good job and keep making videos please.
Oh man, as a beginnerDev, i'm really really proud of using the same logic as you before seeing this video, really got me in a "yaaah, i'm in the right path!" mood. Your refactoring is amazing, btw. It's a thing nobody covers, so your tutorials are complete, not that "do this, do that", and i appreciate it so much. Thank you! Keep up the good work
Nice work Nicky! I'm from Brazil and just want you to know that even for people that don't understand to much about coding, you make a lot easier! Thanks for doing this =)
As always
Concise and brilliant explanation!
I love these timestamps that you add.
Can't Thank you Enough!
Definitely Gonnna hit the notification bell.
@@iHeartGameDev Bro You are The best. Can you also please add tutorials on another subjects that'll be really helpful 😁😉😁
Amasing videos (as always)!! Can't wait for the next ones! Really interested in animation based events
These videos are really great man. Appreciate a lot. Please keep making more tutorials!! Looking forward to learn more from you.
Great content! I have been working with this and it is the best mixamo and animation videos out there. Very easy step by step and it is keeping me motivated!
Thank you for making the complex process simple and understandable. I would love to see more educational content for unity from you.
I am learning tons of new stuff I didn't know. Thanks! the whole series is great!
If anyone is having issues with the animations, make sure they are set to loop and exit time has been disabled on the transitions into the blend tree
all the animations?? or just the idle, walk and run?? coz now that i added the code my left input its not working as long with the left shift run
Saved my ass thank you!
Nicky, this is an outstanding series. As an educator myself I really appreciate your level of detail in explaining all of the different options so people can make use of those in the future. What might help though, is a video on what to do if something goes wrong. Maybe a "how to troubleshoot" animation problems video. Speaking from experience, I go through these step-by-step and my results don't always work out. Then it is really difficult being new to the content to figure out what happened. Sometimes the comments section provides a solution, but not always.
This is awesome :) love the clear explanations, as always
Lovin' these tutorials man, so well made!
Top-notch quality right here people! Very thorough and insightful explanation, hard to believe we are getting it for free.
Yes, this series is teaching me just what I needed to know. I've subscribed.
mate you are one of the best out there in terms of tutorial. Your channel will definitely blow up.
you are a great instructor. and your explanations are PERFECT. thank you so much for all of these videos. youre the best!
your tutorials are one of the best - pretty clean and relativly short.
Dude your explanations are outstanding. Thank you so much for sharing such an awesome and important content!!!
I really like that he doesn't treat us as "beginners". Great tutorials for intermediate to advanced level learners!
Great learning resource in the making. Keep it up and best of luck!
This is actually really useful content.
Found you from reddit. Thanks for sharing
LOVE IT! Well done as usual!!
Wonderful tutorial. Clear, concise, and extremely informative. I've yet to see any tutorial go through such lengths to explain these features. THANK YOU!!
One be the most organized tutorial series....i would love to see more
this is an absolutely brilliant video/series. You cover topics and complex features super well. I really appreciate this and look forward to putting it into my own game. Highly recommend this.
Hey Levi! Thanks so much! I’d recommend actually checking out some of my newer tutorials too! I’ve learned a lot since this tutorial was released and hopefully you can learn it too!
@@iHeartGameDev I'm new to unity and all the animated running works but my character isn't working. I'm using unities in built animation system as well as simple cubes for the character so does it need to be a proper rigged character or am I doing something wrong?
Straight on point, explaining everything even when its not used, what more can I ask for?
Oh, wait, I know... More videos! :D
Bro your video are so well edited and jam pack with useful infos that a beginner need to understand.
even tho i didnt understand the tutorial clearly due to my limit of english language and my knowledge in coding and using unity, i subscribed and joined the membership because of how detailed your explaining was, it is really hard to find people like you in UA-cam who literally explain every single detail and information to the viewer.
THANK YOU A LOT.
Hey! Thank you so much for the support! I hope the content on my channel is able to help you on your gamedev journey!!
This is a very helpful series, walking us through every step in plenty of detail. Highly appreciated. Liked & Subscribed. :D
A small recommendation, please start the video off with what we will achieve at the very end as a point of reference, in case somebody wants to try on their own along the way.
Your tutorial vids are awesome btw. Keep up the good work! ;)
Wow, congrats ! clear, cool, complete. Really an awesome tutorial
This was intimidating at first, but you helped me throught this. Great videos!
This is a "Must Watch Tutorial Series" for any beginner using Unity Animation Tools. If you watch his entire series for Unity Animation you will be far better off in the long run. Thank you soooo much for this upload !HeartGameDev.
Thank you for watching! I think my newer videos are even better 😊
not just learned about unity animation system but i also learned how to write clean code
perfect
this is what i call pure gold thanks a lot bro
Thanks so much for the kindness Ana! Really happy to have helped you learn!
Your reminder at 12:53 is very much appreciated! Often time for beginner like myself this is often overlooked when overwhelmed by the code.
Amazing! Thank you! I love to hear that :D
Good Job Nicky!
Your explanations are always clear and precise
Super happy to see that your channel is growing :)

@@iHeartGameDev
Yes!! I’ve been waiting for this!!
These are very useful and well explained. Thank you for this videos.
Now I understand about these 2D options, better than Unity documentation itself LoL. Thanks for your great tutorials, excellent explanation. Your videos can be masterpiece soon. Can’t wait for new videos.
This really helped me out tons! Thanks Nick :)
the Goat at animations tutorials
Awesome tutorial, thanks for making it so well!
You have a wonderful channel compared to other unity users! Great work 👏🏾
Great Series Man !
It will be helpful for if u put a episode number in each episode's thumbnail of the series.
Otherwise we always want to check the playlist to get to know which video we wanna see next when we have finished an episode.
You did a really great job. Superb tutorial series
Hi, thank you so much for this tutorials, english isnt my native language but you managed to clearify information even for someone like me, highly appreciate your hardwork, keep going!!!
I love the way you explained blend tree and I really understand very well thanku so much ❤️❤️
Thank you for watching and the kind words!!
Fantastic videos , clearly understandable . Thank you !
These videos are exactly what I was looking for
What a journey!!! Amazing work!!! 👏
i give up while seen all this variables xD your coding completely amazing and pro
so i decide to do it with myself
it works too
Best tutorial clean, easy and on point
this is the best tutorial series on the internet(including paid ones)
Thank you so much for the videos. It is such a great help.
Damn all this time learning unity felt like i was just copying someone elses work, and to be honest it was just that, simply because every explanation didn't actually learn me to develop features myself. This is probably the first video that not only taught me something, but gave me ideas on how to implement stuff myself. I'm now thinking about making a blend tree system that merges different aim animations through camera rotation. Man, thank you. For real. You are amazing!
I know this video is years old, but I still go through and read all of my comments. I love these types of comments because they really hit home that the direction of quality vs quantity on this channel was the right approach. Thank you for taking the time to write it.
@@iHeartGameDev I'm currently going over your state machine videos, and altough i don't understand everything yet, i think its important to learn about more abstract concepts in programming as well, and learning about OOP concepts like inheritance, polymorphism and so on is really cool. You really explain things well, i'm very thankful for your work!
You are the best man!! the best tutorial I have ever seen
Nice tutorial, Bro! I really thankful to you for all dedication and nice content. Waiting for new videos :)
Excellent tutorial. Easily S tier among all the tutorial makers.
The coding stuff is standard fare - but the refactoring part at the end is absolute diamond level good.
Thank you so much! I hope the rest of my videos meet the same quality!
You are amazing, the details the video edit the method the way you teach its all perfect thank you very much 🌹🙏👍🏻
So helpful even after 3 years! Thank you
Amazing explanation, please keep going!
Thanks a lot for such great content, mate! Definitely SUB!
Excellent tutorial mate❤
Genuinely excellent tutorials.
Really good content man thanks a lot!!
Thanks for creatiing such amazing tutorials...
Just AMAZING!!! Ty for that class :D
Thank you for watching!
Thanks for creating this tutorial series, I'm learning loads about how Unity animation works!
One note on the acceleration + deceleration: it'd be cleaner to use Mathf.SmoothDamp, or even Vector3.SmoothDamp to damp between desired values.
Here's what my implementation ended up as:
void Update()
{
// Grab inputs.
var w = Input.GetKey(KeyCode.W);
var a = Input.GetKey(KeyCode.A);
var d = Input.GetKey(KeyCode.D);
var leftShift = Input.GetKey(KeyCode.LeftShift);
// Compute desired Z.
var desiredZ = 0f;
if (w && leftShift)
desiredZ = walkSpeed;
else if (w && !leftShift)
desiredZ = runSpeed;
// Update Z.
velocityZ = Mathf.SmoothDamp(velocityZ, desiredZ, ref smoothDampForVelocityZ, smoothTime);
// Compute desired X.
var desiredX = 0f;
if (a)
desiredX -= 1f;
if (d)
desiredX += 1f;
desiredX *= leftShift ? runSpeed : walkSpeed;
// Update X.
velocityX = Mathf.SmoothDamp(velocityX, desiredX, ref smoothDampForVelocityX, smoothTime);
// Update animator.
animator.SetFloat(velocityXHash, velocityX);
animator.SetFloat(velocityZHash, velocityZ);
}
An additional improvement would be to use Vector3.SmoothDamp as mentioned earlier. Also, the input vector should be normalized so the player's diagonal movement is equal to cardinal movement.
You did a great job!! Thank you!
what did i jusr saw???? god damn, the most glorious tutorial in the internet!!!!!!!
i subscribe immediately
Excellent tutorials after watching your entire series to date. Thank you! Other tutorials (including paid) for Unity only told me to do things, but didn't explain why or what the difference between was. I really appreciate the time you take to do this. I also learnt something entirely new with the ? Variable1:Variable2 code. Never saw that before. Always used if statements. Really looking forward to the next part as that's what I'm must stuck on currently. When's it coming out please? :)
@@iHeartGameDev That's great to hear! Waiting with bated breath! :D Thanks again!
Thanks for video. Bro your oratory awesome and explanation is simple and descriptive
So nice of you! Thank you!
whole your tutorials are great!
Such a great video, thanks a bunch man!
Thanks again for watching Nathan!
Thanks a lot for this series, I have been struggling to correctly understand animations and this is a lifesaver
Really concise and straight to the point tutorials, each one self-contained yet better paired together, I ended up following the entire series to make sure I didn't miss anything and ended up learning really useful details on top on what I already knew and I also didn't feel bored or overwhelmed
Each one of your tutorials is god tier quality and really thorough, not just being a "follow along" but also allowing me to get a deeper understanding of what we're doing in a simple way
This is just amazing
Thanks so much Ignacio!
Everything you do is magic.
No doubt, Nikky should be awarded. Subscription is a duty^^
wow, Amazing tutorial man, you can tell how much work you put into them. guarenteed with this kind of quality your subs are gunna go up fast haha :D Can you make a tutorial on holding a gun, or item, maybe being able to point it around (is a seperate animation necessary? :o)
@@iHeartGameDev totally worth the wait, :D just subbed!
For anyone who's forward animations are working but the strafing ones are not unless you press forward first:
Make sure that the blend tree is your default animation
If you want to have another one as your default animation, make sure you make one transition that checks if velocityZ is greater than 0 and a sepparate one that checks if velocityX is greater than 0
Really Amazing video, helped me a lot♥
Glad it helped!
I did it alone! LET'S GOO! Took me a bit but it's actually pretty intuitive.
Heck yeah! Way to go!!
