The fact you timestamped every little piece of this video shows next-level dedication to making the information accessible.

[@iHeartGameDev]

Thank you Kulak! Happy to hear it’s worth the time investment!

[@sinify6676]

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.

[@T8BB]

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 KZbin who literally explain every single detail and information to the viewer. THANK YOU A LOT.

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 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.

[@SassyPantsy]

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!

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

[@captainvaughn5692]

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!

[@iHeartGameDev]

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.

[@captainvaughn5692]

@@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.

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 :)

[@chrisdewitt1598]

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.

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!!!

[@nucleartide]

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.

[@Random_Guy420]

Bro your video are so well edited and jam pack with useful infos that a beginner need to understand.

[@zardify_]

Just a heads up for them folks here; Been doing stuff with Unity for ages now (~6 years). This seems so easy every time you get to it... up until the point where you're still adjusting to the engine. Once you have an idea or you're trying to implement a concrete design, it suddenly seems to feel really rigid, and impossible to adjust to perfection. If you're going into the last camp, know that you'll have to mix blend trees with normal states, layers and sometimes handle root motion yourself from script, even. You'll have to do things not even documented by Unity themselves... XD

[@buysmartter]

I am learning tons of new stuff I didn't know. Thanks! the whole series is great!

[@kalebmcgregor2993]

Maybe it's just on the patreon project files but at 19:28 when you are scrolling through the code, I didn't see mention of locking left and right, just locking forward. That's cool and all just thought it was a weird jump in logic and made me go back and forth a couple of times to catch it.

[@ironheavenz]

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

[@ironheavenz]

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

Hello, your videos about the unity animation system have taught me a lot. I have never coded before and I thought that this could be useful for anyone who is not that smart like me. I don't understand the purpose of a parameter (-0.5,-0.55) Run dec to walk if I have already stated that it will decelerate if > -0.5 is true. I know it locks the variable to the desired number but why doesn't > -0.5 do the same.? // Condition: what will happen: what won't happen: // 1. Left, larger than -0.5 or -2 will -accelerate until -0.5 or -2 Won't go past either number. // 2. Left not pressed, smaller than 0 will + decelerate until 0. Won't go past 0 // 3. R/L ! pressed,not 0 within (-0.05-0.05) reset to 0 if in parameter Won't go past ( -0.05-0.05 ) // 4. run+lef press, smaller than -2.0 reset to -2.0 if it goes past Won't go under -2. // 5. Left, smaller than -0.5 decelerate to -0.5 Won't go unde -0.5 // 6. left,within (-0.5,-0.45) reset to -0.5 Won't go past (-0.45,-0.5) idle to walk // 7. left, within (-0,55,-0.5) reset to -0.5 Won't go past (-0.5,-0.55) run to walk //5.6.7.= Only walk. (else runpress) //Possible outcomes : left pressed pressed || Left pressed and runpressed || Left not pressed || Runpressed // Lets see what happens when: // --left only: // 1.accelerate until -0.5. //--left not pressed: // 2.deaccelerate until 0 but actually until 3. (-0.05-0.05) then reset to 0. //-- left+Runpressed: // 1. accelerate until -2.0 //--!Runpressed, left // 5. (else) Meaning X is smaller ("larger") than walk, it will decelerate until 7.
