2 - Turn in Place - Bow And Arrow - UE5 Blueprints

[@gail_blue]

This is a great video, but it gets a little hard to follow, so I'd highly recommend making a copy of your project after the first tutorial, so that you can do this multiple times. You'll want to add a lot of print_strings and debug objects (I suggest putting an arrow at the character's feet), to really understand what is going on. If you're using this with 5.3.2 (or later) you'll need to change all the animations on your ABP_archer (notably turn_left and turn_right) to looping by checking "Loop Animation" in the AnimGraph. For example in: AnimGraph>GroundLocomotion>Turn_Left(state)

Hi, Stephen, thank you so much for this series. For anyone still having issues with the Turning in place, at time 28:16, before setting the Distance Curve, add a "Map Range Clamped" with the following ranges: In Range A: -62 In Range B: 0 Out Range A: -90 Out Range B: 0 It's not a fix, but it solved that issue and thus works for me. Thank you again and keep up the good work.

[@boomwowsion64]

For anyone who wonders how Subtracting Yaw Excess would fix the Root Bone Rotation, here's my understanding: The very first tick when the animation just activates. The Last Distance Curve is 0 cause it uses the default value of Distance Curve and the Set Last Distance Curve excecutes before the Set Distance Curve updates the Distance Curve value to -90. (The following examples are based on turning left and Root Yaw Offset being 90 when the turning animation initiates and remains the same for the rest of the animations) 1. If we don't use the Yaw Excess subtraction. So, the very first frame, the Delta Distance Curve is -90. For example, if you are turning left, the very first frame, the Root Yaw Offset would then be 90-(-90)=180. The second frame, Last Curve Distance is -90, let's assume the Distance Curve being around -89, the Delta Curve value would be somewhat around 1, then the Root Yaw Offset would be like 179. This is why your Root Bone Rotation gets messed up. It still rotates, but the Root Yaw Offset goes from 180 to 90 .You can test it out by setting the default value of Distance Curve at 90, then your first turn will work just fine, your character's root bone rotates normally. But the second time you turn left, the very first frame, the Distance Curve value is 0 (its value becomes 0 at the end of last animation) before it gets updated, so the Last Distance Curve value is 0, then the Root Bone Yaw Offset value becomes 180 all over again. 2. If we use the Yaw Excess subtraction, the very first frame. You still get Delta Distance Curve as -90, the Root Yaw Offset would be 90-(-90)=180. But then, the same frame, you get Yaw Excess 180-90=90, since you subtract Yaw Excess from Root Yaw Offset, the Root Yaw Offset is 180-90=90. Your character stays still the first frame. The second frame goes on with no problem at all and your Root Bone Rotation works just fine. What if the Root Yaw Offset keeps changing? Then you get a little bit more Root Yaw Offet Value (turning left) until you hit the next turn.

[@Lewis-dq2xb]

@DruidMechanicsGameDevelopment Thanks for this!, It seems there are many ways to try achieve the same result, but your worked perfect!

[@icameroni]

Hey Stephen, love your tutorials. About this one I got a few notes. Not all the values of the Distance curve are being read by the tick function. This seems to be because of the default blending-time of the turning animations & the early transition from the time-remaining ratio. This results in only a partial resetting of the root yaw offset. Also, on the first tick the Last Distance Curve = 0, and the Distance Curve is -90. This results in a Delta of -90, so on the first tick of turning the Root Yaw Offset is 180 when turning left for 90. And when turning right 90 on the first tick of turning the Root Yaw Offset is -180. The other calculations somewhat make up for it. The end result for me with the current set up is: when you turn 90 degrees, the root yaw offset will only turn back for around 60 degrees. So, the turn-in-place setup is not entirely working correctly for me, but still does the job. I was expecting that when I turn 90 degrees, the root yaw offset is also adjusted by 90.

[@DruidMechanicsGameDevelopment]

Yep, that's the nature of blending into/out of anims. If you'd like to turn more, you could also edit the curve so that it results in a higher delta as well.

[@boomwowsion64]

The other calculations somewhat make up for it. LOL I have been trying to figure out exactly how it makes up for it for hours and still couldn't get it. Nice notes tho.

[@boomwowsion64]

I just figured it out. Fuck, after about 4-5 hours of thinking and testing. Here's how it works. As you said, the very first tick when the animation just activates. The Last Distance Curve is 0 cause it uses the default value of Distance Curve and the Set Last Distance Curve excecutes before the Set Distance Curve updates the Distance Curve value to -90.

[@Jalupus]

Thanks Stephen! Really appreciate the help.

[@aka.Xavier]

First, Thanks to Stephen for creating this video. You are truly an invaluable asset to the Unreal Engine community. I recently completed your UE5 course, and it was an incredible experience. However, I have a question for all the viewers . Do you truly understand the concepts being presented in this video, or are you simply following the steps to achieve the desired result? I really want to know what am I missing here to understand it ? Math or 3d Animations consepts or what exactly ?

[@DruidMechanicsGameDevelopment]

Congratulations on finishing! If you don't understand this video, you may want to find which parts don't make sense and research those points specifically.

[@SoldierG6543-2-f]

Unfortunately I wasn't able to get this to work, Root Yaw Offset stays locked at 90/-90 and never exits the animation as a result.

[@Rev0verDrive]

Having a problem with Right turn. It'll play the animation once and then start accumulating the negative rotation. As soon as I press forward it'll spin out until it reaches zero. Then I can get 1 right anim, very little rotation applied and accumulation begins again. Left turn works fine, somewhat. It'll rotate, reduce 30 from RYO. When it reaches 90, another play of anim and a reduction of 30ish.

[@arcailprime]

The same thing! Have you solved this problem ?

[@jbm1444]

Everything is working fine, except when turning left or right, the turning animation keeps looping. I've rewatched this tutorial so many times and I can't seem to find where the problem is

Same thing! It's like it stuck on Last Frame. Debug Shows that distance curve is stuck beetween 0.9 and 1

[@kyleb3094]

different problem but same, waste of hours trying to debug this speghetti mess

[@gail_blue]

If you're having trouble following the Root Yaw Excess, this part is only needed because the distance curves in the data are well... stupid. They need to go from 0 to 90 (and minus 90) respectively. 0 because at the start of the turn, your yaw offset is 0 and +/minus 90 to turn left and right respectively. Then you also need to reset the value of LastTurningCurve back to zero, or it will carry over into the next turn (I do this whenever the ABS of lastTurningCurve is higher than the ABS of turning curve). I suggest making your own curves (only a start and an end point are needed if you use smoothing). As a little bit of tech art will save you a ton of programming.

[@DruidMechanicsGameDevelopment]

Good points!

[@gail_blue]

@@DruidMechanicsGameDevelopment Why even use RootYawOffset anyway? You get similar (if not the same) results by turning off "UseControllerRotationYaw" and then rotating the actor to the base aim rotation if it's moving. (just send the rotation from the turn-in-place animations to the actor and have them rotate by that too.) Maybe it's some sort of Network/Multiplayer thing? But then you could just enable "UseControllerRotationYaw" when it's moving? There must be a good reason for jumping through the giant hoop that is RYO if Lyra is using it?

[@remymachado7046]

I found a proper fix for the rotation issue (first frame remaining distance mismatch and excess). With the following fix, you won't need to handle "rotation excess" as you will turn exactly the correct amount. I made an example at the end of the comment that may serve as a TL;DR. Note that I'll use the term `remaining rotation` instead of `distance curve` for my explanation. I was inspired by Lyra's starter game animations. They contain a second curve called `TurnYawWeight` which is equal to `1` when turning. 1) Therefore, make sure to create a second curve `TurnYawWeight` on your animation equal to `1` during the turning. As stated in other comments below this video, you may have found out that the `remaining rotation` doesn't start at +/-90 degrees, because the character is transitioning from his old pose to the new animation. With the new curve (`TurnYawWeight`), we'll be able to tell when we are done transitioning from the previous animation. That means we'll rotate the character only when the `TurnYawWeight` curve is equal to one (it will graduately converge to `1` during the transition, starting from `0`). 2) To avoid turning when the rotation animation hasn't started yet (`TurnYawWeight < 1`), we'll keep setting the `previous remaining rotation` equal to the `remaining rotation curve's value`. That will give a delta of `0` -> no turning. 3) When the curve `TurnYawWeight` is equal to `1` we'll know we are allowed to turn. For that, we'll do exactly as instructed in this video: set the `previous remaining rotation` equal to the `current remaining rotation`. We'll get a delta and use it to turn as shown in the video. By doing that we'll turn exactly the amount of rotation given by the animation `rotation's curve` (+/-90 degrees). However, we'll only rotate by the animation's amount of rotation (90 degrees) given the current process. But we'll want to do wider turns (e.g, 135, 180 degrees, ...). We'll easily fix that by calculating a rotation factor which will increase the rotation rate. For instance, if we want to do a 135 turn, we'll apply a rotation factor equal to 1.5 on the rotation delta in order to turn the perfect amount. 4) To compute this rotation factor, we do a `SafeDivide()`: `RootYawOffset` / `RemainingRotation`. Now that we got the factor, we'll only use it if it's greater than `1` -> we multiply `delta rotation` by the factor we just computed (and we set the delta equal to this new value). Don't forget to remove the "excess rotation handling" process shown in the video as we no longer need it. Done! Here's an example: 1-2) The animation is transitioning, `TurnYawWeight` curve is equal to `0.02` -> we don't turn 1-2) `TurnYawWeight` curve is equal to `0.31` -> we don't turn 1-2) `TurnYawWeight` curve is equal to `0.67` -> we don't turn 3) `TurnYawWeight` curve is equal to `1` -> we TURN! 4) `RemainingRotation` is equal to `90`, but the `RootYawOffset is equal to `-108` degrees. We compute a factor of `1.2` 4) Instead of turning let's say `6.4` degrees (rotation's delta) during a tick, we'll turn by `6.4 * 1.2` In the end we rotated `108` degrees as needed. Now, the animation might look a bit off if you turn way more than it's intended to (turning 180 degrees with a 90 degrees animation, you'll get a small foot sliding). In this case you can use different animations to cover a wider range of turning. Hope it helps. Great video as usual, thank you.
