How to Make the CLIMBING MECHANIC from BOTW | Legend of Zelda in UE4 #17

[@CobbDev]

*QUICK FIX* Hey everyone, after some research I found out UE4 can have trouble with landscape detection from line traces every frame. The fix I found is in the Wall Trace macro that we create at 0:53, use a BOX TRACE by channel instead of a line trace. The start and end will be the same, half-size you want something really small to emulate a line trace (since a larger box trace can mess up our min/max angle clamps). A half size of 0.01, 0.01, 0.01 worked well for me. Orientation will be the ACTOR FORWARD VECTOR -> RotationFromXVector node. Everything else can be left the same. I suggest everyone do this even if you don't have landscape in your game, it can eliminate some jitter problems in general

[@cedricodigital]

Hey thx for the fix.Unfortunately i seem to still loose the box trace very rapidly from up or down, or left to right. Did you experience that as well ? THX for this great tutorial BTW!

I had to slow down to 0.5 and is still to fast :( I gave up following this video

[@smcfadden1992]

ive watched this video at .5 speed and have been working on the first 4 minutes for about an hour and a half my laptop died..

[@Will_Forge]

Hmm... I'm upgrading this to UE5 which has a different movement section in the character controller's blueprint. I just did everything up till 5:00 and mine doesn't move on the wall correctly. When I start climbing, mine moved in a direction based on its current momentum, so on a sheer wall it's always left or right, and on a sloped wall it can be up as well, but the issue is that as I hold movement in a direction it not only always moves in the direction of my inertia, but also slowly slows down. It gradually slows down until the climbing movement stops entirely as if the movement is exclusively based on that inertia and the physics engine is slowing the inertia down over time. I'm gonna have to go over everything again up until this point to debug the situation. Hopefully I can figure it out. I am also considering a more Assassin's Creed or God of War Ragnarok style of climbing system, though, so maybe if I can't figure this one out I'll comment out the code and set it aside for another tutorial. By the way the speed of the video is pretty aggravating. I wish it was at 1/2 this speed and 20 minutes long, and I might still slow it down a bit like that. More thorough explanations would also be appreciated to fully understand what's going on in the code since the less detailed you go the less future proof the lesson is to future versions of UE. Like how I'm having issues just updating this to the modern UE5.4.

[@Will_Forge]

Well I solved the stupid "movement being a deteriorating value of inertia" bug. I wish I could post screenshots to show how dumb this was, but I'll do my best to explain in text. In my WallClimbMovement function, in the calculation of my first line trace's End vector, I had gotten the capsule radius as directed din the tutorial, and then multiplied by 2. But my mistake was that I somehow outputted a vector from that multiply node instead of a float. That went into the other two multiply nodes as vectors and the whole thing was forked in grass, as they say. Now it's working great on a slope for climbing upward, and also for side to side, but it won't go down the wall at all. Further, it's not going up the wall on a sheer vertical wall either. Only sloped ones. I suspect my line trace isn't hitting anything when attempting to check for upward movement. Perhaps I need to pull the start of the line trace further away from the wall because maybe it's firing off inside the wall or something. I suspect this since on a slope it likely has more space due to the wall sloping away, but on the sheer wall it's likely too close and firing inside the wall. I'm speaking now without having actually done something about this because I'm still not 100% sure where to add something for that. This is why I preferred the more detailed explanations from previous tutorials in the series. EDIT: Oh, duh! I turned on a persistent draw debug type on the line trace at the start of WallClimbMovement, and it was absolutely missing the wall entirely when I went downward, and was inside the wall when I went up. Now I'm realizing that it's using the forward/back mathematical values to move the start point forward/back to the character, meaning further from or closer to the wall. The reason it won't go up on a sheer wall is because every single line trace is being drawn on a perfect horizontal axis. It's not moving the line up into the Z axis when I press "forward". So yeah, I don't go anywhere.

[@Will_Forge]

Oh my GOD, it's always something absolutely stupid. I didn't pipe in a "get actor up vector" into my WallClimbMovement for moving up and down the wall. I mistook the built in "get forward vector" node for being the one I needed. In other words I didn't adequately understand what I was doing when translating from your UE4 to my UE5. So dumb. 😅 That being said I would almost certainly not have missed this mistake had the tutorial not been designed for the Flash. 😆 Finally back to 5:00. Also my animations are jacked up, and my own "fix" did not do the job. I just moved the pelvis lower, but forgot to move the IK objects. Should have just moved the Root or something, I suppose. Gonna have to redo them as Quinn's feet are next to his ears. 😆

[@rocketpoweredchimpgamesphi7798]

FINALLY! After 4.5 days... I finished a 10 minute tutorial! Mostly seems to work although have some fiddling around with Camera Look direction in my game messing up some of this if you aren't looking dead ahead, also the Mixamo animations I used are rubbish (if you use the Climbing Up one, make another one which is the Climbing Up but played in REVERSE as the "Climbing Down" one they have is appalling, also the "Braced Hang" Mixamo animation actually jumps DOWN and then INWARDS so you end up inside things when used on this project (tried changed to force root motion, and root motion lock but didn't make a difference!). 10/10 for the code, 1/10 for the Speed it was presented at! Sorry! Update: Be very careful on what you set your animations to in your blend space, I "think" I may have reused by mistake (as I have other systems that use the same animation) an "hanging idle" animation sequence from another tutorial which HAVE "enable root motion" and "force root lock" set on it, this will prevent the character moving/transitioning in the animation blend space - totally preventing movement!!!! So watch out for that! :o)

[@ParaEquinox]

I did everything, and repeated twice, but mine dosen't work properly, the player just fly around when the camera is not aligned with him, so the angles of movement are not world absolutes, and I cant make the angle wall in the right vectors to work properly, only in the Up vector

[@androsiel]

If someone’s character does not move after setting up the “wall climb movement” function, then this may be because in the “walltrace” macro the start of the line trace is inside the wall, so you can pull the start back a little (add to it a forward vector with a negative multiplier)

[@1d33f1x3]

I love that everything I've been looking for in a climbing system is in one concise video. I think it took me about 2 hours to watch the the 10 minute video because I was stopping and starting so much. I have a few bugs that I still need to work out (my character detaches from the wall when I try to climb up, but side to side and down work perfectly). Thank you!

[@MZONE3D]

I have similar to you, the character buries itself in the wall while climbing up and then magically reappears :D

[@Shrooblord]

Hey there! InputAxis variables are from the old system Unreal used for controller input, which have been deprecated in the current version of Unreal. You're looking for the Enhanced Input System, and creating your own InputActions that detect movement directions.

[@chancemcdonald4128]

Thank you for this great video. I have 2 things I would like to share. 1) inorder for the wall normal to be detected correctly in UE5.1 I had to enable trace complex in the line trace in the wall trace function without it active the ceiling normal was not being detected correctly. 2) I would also add comment blocks in your code in future videos so large sections of nodes could be easier to understand. But I want to say again this is a great video. TY.

[@abdiasnemo2634]

Wow I cant believed it, I manage to fallow along and coded the system too! I had a bunch of bugs from my other systems interacting from this system but I manage to solve them! I am so proud of my self. Now I have a bug when Vaulting Up, if I keep holding W it slows down the action. Got no idea how to fix it but Ill keep trying.

[@rocketpoweredchimpgamesphi7798]

Add a bool toggle to block the key press input until you release the key, as I imagine it is repeatedly calling Vault over and over again!

I solved moving up and down make sure you have this forward Axis on the proper move input node

[@velvaraart1007]

I have an issue where everything works perfectly only if i use unreal's basic shapes. As soon as i bring in a model from blender, or if i use brush editing on geometry, The character will attach correctly but moving will mess up the ortation and then stops at a weird angle(usually rotating downwards or sideward). I have tracked this issue to the "Set Rotation" node at the end of the "Wall Climb Movement" function. If I disable this, I am able to move on the mesh(with all the constraints from not being able to rotate). Once i plug it in again, it just attaches, turns if I move and gets stuck on that position until the character detaches from the wall. The closest to what I'm experiencing would be to put a "1" instead of "-1" before the "Rotation from X Vector" node that is plugged into the "RInterpTo" node before the "Set Actor Rotation" and trying to move once in the wall. Does anyone have any idea why this might be happening?

[@mooseywoosey8734]

Does anyone know what the UE 5.4 Equivalent for the node he's dragging off for casting at @2:52 . I'm just an artist with light blueprinting knowledge man, this is promising and much appreciated but I feel like I'm being strangled lol

[@Exponerad]

Thank you so much! I finished this using half speed and it only took me 10 hours, but it was worth it! Also, do you have any tips for making your mesh not stick to walls if the capsule radius is small enough to look like the hands and feet are touching the wall? Keep up the good work!

[@elektrofox2746]

How would you arrange this logic if you want this to work the way it does in BOTW where you don't need to initiate climbing with a keypress? I can think of a few ways but they all feel a little hacky.

[@Exponerad]

My guess is that you could do an on collision event with like a sphere collision so it triggers. But then you have to set it to a custom collision instead of world or dynamic.

[@mincvinyl]

@Cobb Dev did your final vault up part work automatically if you climbed to the top of a block? I also appear to have a bug where if you spam climb in air you can hover for a brief moment. Basically it is like having a parachute if you spam climb.

[@mincvinyl]

Fixed the vault up issue, it was due to setting the max turn angle too high. The parachute bug was caused by detach from wall on button release.( I am not using a toggle climb) To fix it, I had to make a boolean [Is_Climbing?] which is only active while climbing. So on button release it will only detach from wall if [Is_Climbing?] is true

@@phobos_4708 it also happened to me. For me, it was that inside the inputs section, I had plugged the movement up/down to a "GetActorForwardVector" instead of a "GetActorUpVector", probably because i just plugged the same nodes that were being used for normal movement inputs. When climbing, the character doesn't go forwards/backwards, so it looks like it's not moving.

When turning corners (or going back over the same corner) the rotation is off, i.e. the mannequin is still facing the original orientation. Jumping up on the wall and reattaching fixes it. Any ideas?
