Oh damn, your tutorials are just the best... As an animator myself, I'm really glad that you keep the channel a bit "animation-heavy", but your coding is just so well executed. Even though I usually already know most of the things you're talking about in your vids, I always watch every single one of them, because they are probably the best Unity-centric content available. You're doing a great job man, thank you very much! Also I was wondering if you considered telling us something about inverse kinematics? I mean, most of it is quite well covered (at least quantitatively - there's quite a lot videos on that topic), but the tutorials are most often quite incomplete and not well done. There's surprisingly very little video material on well executed 2D runtime rigging, but I guess 2D is not your cup of tea. But any in depth tutorial on runtime rigging would be great! Cheers from Czech Republic, thank you for your vids, keep up the great work and have a great day!

[@rogerwarford1517]

Love these videos! For what it's worth, there is a small error in handleJump() (26:09 in the video). Lines 75 through 78 should be: float secondJumpGravity = (-2 * (maxJumpHeight * 1.5f)) / Mathf.Pow(timeToApex * 1.25f, 2); float secondJumpInitialJumpVelocity = (2 * maxJumpHeight * 1.5f) / (timeToApex * 1.25f); float thirdJumpGravity = (-2 * (maxJumpHeight * 2f)) / Mathf.Pow(timeToApex * 1.5f, 2); float thirdJumpInitialJumpVelocity = (2 * maxJumpHeight * 2f) / (timeToApex * 1.5f); Note that we are multiplying by 1.5 and 2.0 rather than adding 2 and 4. This only matters if maxJumpHeight is set to a value other than 4.

[@clintonmansfield6364]

I know this comment is a year old now, but would you call this an error or a preference? I personally prefer the addition and not the multiplication for any value of maxJumpHeight

[@rogerwarford1517]

@@clintonmansfield6364 I personally consider this a bug because if you do addition the second and third jump are not proportional to the first jump. So for example if maxJumpHeight is 2, then the second jump will be double the regular jump, rather than 1.5 times. Likewise if maxJumpHeight is 8, then the second jump would only be 25% of the initial height. I think this would be confusing if you tried to reuse this code and needed a different maxJumpHeight.

[@mowalduchiwa1560]

[@guille_sanchez]

Hi @iHeartGameDev! First of all, thanks for the amazing tutorials. I want to give some feedback on the jump button release: Wouldn't it be nice if we set a min jump height for the "jump button release"? If there's no min jump height, then when you spam the jump button rapidly there gives inconsistent jump arcs and that feels really bad. If you take Hollow Knight as an example, when you tap the jump button rapidly the character hops quickly but with the exact same jump height (which is the minimum jump arc/parabola/or time, depending on which implementation is used), so the arcs of the jump for the min jump are always constant. The last time I coded the min jump I did it by comparing 2 things in fixedUpdate: (1) Jump Button UP and (2) the current Y velocity is less than a threshold that you set (this threshold could be your "initialJumpVelocity" - "a small amount (for instance, minJumpVelocity = initialJumpVelocity * 0.9f)". If the initialJumpVelocity is 10, then the minJumpVelocity = 9). This ensures that at least the character is going to travel a minimum distance (the distance travelled from the initialJumpVel until it reaches the minJumpVelocity by deceleration) before falling back down. A drawback of this implementation is that is less intuitive to set up, because you have to test the values until you find the min distance travel that you like for your jump. My question is, given your current implementation, is there a better way to set this minimum Jump height that suits the rest of the Jump with the verlet integration? The one I suggested would do it (In fact, I tested with 60fps and with 800fps and the results are very consistent across framerates), but its consistency is similar to the euler approach, there are still a really tiny amount of error, not really noticeable for a normal jump. However, if you set the jumpHeight to a really large number, then the inconsistencies could be a bit more noticeable (still low though, but worth to be corrected).

[@FAISAL-ky7ps]

I always love your tutorial XD

[@iHeartGameDev]

Thank you!!! I hope it helps!!

[@mihaistanciu2487]

The biggest problem in jumping is to be able to sync the animation with the actual jump. You chosed some settings on animations without any explaination of why you did that or what that mean(like set the root transform position etc). Judging on your previous videos I was expecting more. Anyway, keep up the good work.

[@iHeartGameDev]

Hey - thanks for watching! I tried my best here to replicate Mario’s instantaneous transition and stated why we were modifying the transition duration to allow the animations to blend better. There should be bits of explanation for most everything incorporated in the video, including why we were modifying animation transitions.

[@andresinish]

For me the static poses weren't working for me, because the timing was a little off, but i replace them with some actual animations and it was a whole lot smoother and the timing was way better, i guess you could try that instead. :)

Wow just perfect, it works sooooooo well! Anyone know how to add air control while jumping? Is there a way to isolate the y velocity of the player rather than use current movement.y?

[@Hiturion]

regarding the physics, there is a bit of a confusion between Acceleration and Velocity. But we get your point ;).

[@ichliebelongboarden]

Very helpful, thanks. There is a correction though. When you land back on the ground, the y velocity is 0 and so is the acceleration. This is because you are no longer moving vertically. If your y velocity was nonzero, then you'd be moving vertically. If your y acceleration is nonzero, then your vertical velocity would be changing. Neither of these are true, so both y vel and acceleration are zero. Also, your Verlet integration isn't correct. You are effectively just doing Euler integration with half the acceleration you want and declared with the gravity variable. Simply put, Verlet integration yields v(t+dt)=v(t)+.5(a(t)+a(t+dt))dt, which in the case of constant acceleration like we have here, that is the same as Euler integration (because a(t)=a(t+dt)). You only want Verlet integration if you have non-constant acceleration. So just use Euler integration with gravity cut in half, if you like the effects of what your code did.

Great tutorial thanks for posting. I have a question, currently the character stays in the jump animation the entire jump. How do you impliment a falling animation once the character reaches the apex of the jump?.

Thanks! There is logic already in the script that incorporates checking if the character is falling. Seems like a solid spot to switch the animation too!

Hi, just amazing these character controller tutorials. I'm learning about game developing and programming and I loved your way of explaining. As I remember Mario doing the 3 jumps without pauses when touching the ground, I tried to apply the same concept in case the jump button is pressed as soon as you hit the ground execute the second jump by changing the if of "handleJump" to " if (characterController.isGrounded && isJumpPressed)" is there any problem I didn't notice when removing !isJumping?

This video is really informative. I'll definitely be able to use some of this stuff for a kinematic Rigidbody character controller. Just need to convert from the CharacterController, I've wasted so much time on. Try doing jump-through platforms, without turning off the platform's collider. Spoilers. You'd think using the collider.isTrigger = true; function of CharacterControllers would do it. It doesn't. CharacterController controller; controller.detectCollisions = false; Doesn't actually do anything. I'm in 2019.4.29f1, so ymmv in the 2020 version, but it simply doesn't actually do anything in my version.

That’s because the current movement implementation isn’t acceleration based, I believe. You would need to handle movement on the x and z axis differently than we currently do. More like three two dimensional blend tree tutorial I released on this channel. Rather than how we implement it here, which is purely based on player input.

I watched the animation series and I am working to make cool jumps. I would like to know more than unity.physics. the code I am using is: Rb.velocity=velocity.y+float. It works fine but the problem is that I want my object to look heavy. But useGravity is a bool and API is not accessible. Plus due to zero air resistance mass doesn't make any change.

[@iHeartGameDev]

Hey Sufian! Thanks for watching the series on animation! Currently I’m not handling rigidbody physics. I think we’ll get there eventually though so stay tuned!

[@Bidule200]

Gravity value is accessible in Project Settings > Physics (default is 9.81 like on Earth). It's a global setting, so you can't tune it for every object. For air friction (what makes objects look light or heavy) the rigidbody parameter to tune is Drag (and Angular Drag). Anyway, you shouldn't use default Gravity for a playable character, you should compute your own and apply it as a vertical acceleration when your character is not touching the ground.

I know I'm a year late to this, by why use a pair of Dictionary. They're expensive to look up. Why not have used a single (float Velocity, float Gravity)[]? Where index 0 is the first jump, index 1 is the second, and so on?

I've encountered a problem after finishing all the areas until 19:00, when pressing jump my player gets yeeted, so to make small jumps i need to lightly and quickly tap the jump button, any idea how I can fix this? I've gone through the code 3 times and it's all the same.

[@JahidulIslam-ev1zo]

I am having the same issue, have you found a solution?

[@JahidulIslam-ev1zo]

Nevermind, my solution was that float previousYvelocity = currentMovement.y; float newYvelocity = currentMovement.y + (gravity * Time.deltaTime); float nextYVelocity = (previousYvelocity + newYvelocity) * 0.5f; currentMovement.y = nextYVelocity; it was currentMovement.y += nextYVelocity; before and now i removed the plus and its fine.

[@michaelpestanaluis-gamedes3518]

@@JahidulIslam-ev1zo Just saw your reply, and it worked for me, although I had to change the 'currentRunMovement.y += nextYVelocity to currentRunMovement.y = nextYVelocity as well, as the same problem would occur when running and jumping at the same time

Can You Make A double Jump move

[@jennypenny8965]

This video is great! Newer coder here and I am having a problem. I coded exactly like you but my character does not move forward when jumping like yours does. He can jump from the idle position but when walking or running, he kinda stops and jumps in place and then continues on. I've been over the code a bunch and I don't think I missed anything. Any ideas?

[@ryanzenn6896]

I'm having the same problem. Have u fixed it?

[@jennypenny8965]

@@ryanzenn6896 no, I was never able to fix it. I ended up reverting back to my old jump code and not using the input manager due to a deadline I needed to meet :(

[@ryanzenn6896]

@@jennypenny8965 I just fixed mine. I unselected the "root motion" of the character and it worked.

[@jennypenny8965]

@@ryanzenn6896 oh nice! That's good to know because I may actually go back to having different jumps.

Hi o/ Dunno if is something related to the scale of the objects of my scene. But when i press jump my character skyrocket and i got an error that says: "due to floating point precision limitations, it is recommended to bring the world coordinates of the GameObject within a smaller range". Can you help?

[@zgouman]

Same problem here. Do you solved it?

[@celsoae]

@@zgouman coundnt solve it yet.... i go back to the first gravity system. and im using it.

[@zgouman]

@@celsoae I solved it. Idk exactly why but i deleted SetupJumpVariables and HandleGravity in the script and write it again. I think i had a wrong symbol for the math but i dont know which.

[@celsoae]

@@zgouman Nice! Illinois try this today

[@celsoae]

@@zgouman Same here xD rewrite and is working hahahaha crap xD

[@tigeralt302]

This is so great! I do have some questions: Why do we need to calculate the gravity again if we already set it to a number? Is it to make the controls feel better? (Is that explained in the talk you referred to?) And why is the Jump/Falling still frame dependent if we are multiplying it by Time.deltaTime?

[@Tinfoiltomcat]

I had this question but then I realized the answer. He isn't moving the character to jump, he's manipulating the gravity.

[@angelkaki5707]

Does anyone have an idea of how to make the 3rd jump stationary n not actually make you move??

[@koreanjesus2712]

try disabling "apply root motion" in the animator

[@slavic_sloth]

Maybe someone can help me out here please? I'm getting this weird error when trying to jump. MissingMethodException: PlayerControls.OnJump Due to: Attempted to access a missing member. It only happens when jumping occurs. I've set up the Input Actions the same way, used the scripts the same way (without having animations). Does anyone have any idea what the issue might be? The weirdest part is that it does not effect what's going on in the game as far as I can tell. It's just an error that shows every single time I press the jump button.

[@slavic_sloth]

I figured out the issue. It seems like a bug on Unity's behalf. I changed the default map to and when hitting play it automatically changes over to my input map. But if I use my input map and hit play there will be an error.

[@SevenSinsGER]

My Character is losing all it's foward momentum when jumping which feels really terrible. Anyone knows what's causing this behaviour and how to fix it?
