- This guide is about the spline component and the spline mesh component. I find this useful and one of the most important components you can find in Unreal Engine 4.
Another guide worth to check: • Anti-Ghosting Temporal...

For those watching in 2020 who are wondering why they cannot see 'Forward Axis' or 'Static Mesh' in the Details panel in the game editor; You need to set the variables to public/editable on each instance. To do this, go into the Blueprint editor and press the Eye icon next to both of the variables you created.
Thank you in behalf of regular env artist xD
How do you make it that the character follows and rotates to the direction of the object?
I also want to know this.
@@osakanone create a location offset (in x-axis for example) while updating and incrementing player rotation at each tick (each frame)
for example :
if ( isOnthePipe( ) ) {
// offset location
// update rotation
// isOnthePipe ( ) could be implemented using collision event handlers
Hope this helps

@@khisrowhashimi each tick is not a good idea on performance better to use timers
Everything what you need to do is just updating your mesh/character position using GetLocationAtDistanceAlongSpline. So you simply add little distance when ticking.
It's better to use [ Get Location and Tangent at Spline Point ] instead of [ Get Location at Spline Point + Get Tangent at Spline Point ].
right
Thank you for watching my tutorials, please check also project we are working hard to bring it to Steam and KS (June this year) th-cam.com/video/IBoTsupTudo/w-d-xo.html
We need your support!
Hi Tefel, in the tutorial, I noticed that your player character can jump onto any position on the spline and then follow its path from that position where it landed to the end of the spline. Do you possibly know a good tutorial that can help me set that up please? I can make the player follow the spline from its origin to its end, but not from the position where he landed on it. Tx!
You're right this is what I've noticed too and I really would like to know too
Maybe you've found the solution ?
Sadly I didn't :(
Maybe you should replace the AI and actor by the player component
Ive been looking for this too
Any luck in finding the answer to this?
In the odd case you can't see your spline help points you alt drag out, make sure Game view (G) is not running.
thanks dude it wasnt working for me and finally i found an answer thanks to you
How would you implement this without stretching the mesh but rather repeating it? Also how would you add a random mesh at a spline point?
If you use Spline Mesh Component it's for stretching and bending mesh. It's good if you want to do quick deformation.
For repeating the mesh I would simply use InstanceStaticMesh or HierarchicalInstanceStaticMesh in conjunction with Spline.
Hi, Thank you for your guide !
I follow the steps by when i add a part with ALT key the new meshe is not blend with the first when there is a curve... I can see a space bettwen the 2 and the curve is not smooth. Any idea ?
Sorry fot my english ;-)
this is freaking useful! Entirely a fundamental knowledge in UE! Thanks for the tutorial :)
thank you this is what im looking for, for my network and power cabling.
edit: my cables arent bending whenever it hit the corner. its all straight.
edit2: i forgot to subdivide the faces of my cables. lol now its working fine. :)
Thank, its very useful for me
Hi Tefel, nice tutorial... I would like to know What functions did you use make the character move along the spline? Did you attached and added an impulse/force/velocity with a tick or is there another way to make it constantly move?
Hey Bruno
get distance along spline and set actor location
Explain it better please?
When I use the Alt key to extend the spline, it just duplicates the mesh but will not extend it? help please
did you find any solution?
@@IvanSorce You have to click on the spline point, not on the mesh.
Thanks so much! This is probably about the 3rd time I've watched this!
This is a pretty straight forward, very good tutorial. In 2016, older versions of unreal engine had some problems with Edit Spline so this was pretty useful but now, edit spline tool in UE4 is so much better to use so we don't need to do this anymore. 1 tip, only create this if you are going to continue to add more to the blueprint to make it more interesting and advanced to add additional of whatever you want it to do, events included :).
I have no idea what I just did, but it works. Cool tutorial. You go at a great pace. Most tutorials I've been watching have been pretty slow.
Hello, thank you very much for your excellent training, I have a question, I would be grateful if you could answer it, I want to make a hose with a spline and I made it with blue print, now I want to connect the beginning and end vertex of the spline to two different objects, and when I move the objects so that the hose moves realistically
I really like, that you explained it rather fast and on point. This is rather rare on youtube these days, most make such things to an 1 hour tutorial. I would like to see more :).
There are more tutorials, just after 2 years :)
SLOW DOWN why does everyone think every one can go like their on speed ./
This dosent work
wow thank you very much! I'm coming from Unity, this is awesome!
Mine wasnt working but then i realized I hadnt connected my white arrows together to complete the order of operations. Make sure all of your execute arrows are connected all the way through the chain :)
Good point! Always connect your white arrows together! :)
Is this addable on runtime? So eg a player spawns in a rail and can draw it and even connect rails into each other?
Sure! It's even more useful runtime than in the Editor. Since is component is flexible.
@@UnrealTefel is there also some sort of "ai pathfinding" component, like a train searching exitpoints by itself?
Thanks a bunch for this. I figured this could be done once I saw the spline mesh component, but it was reassuring to see it executed so simply.
So if anyone's getting issues with this Blueprint, I figured out what worked for me. In the ForLoop, set First Index to 1, and the subtraction off your Return number of Spline Points to 1. Then, as opposed to +1 for your second set of Get Location/Tangent values, set it to -1. No problem!
How did you get the player character to grind on the rail?
Thank you for the tutorial!
It's very simple, you check position and rotation at Distance Along Spline docs.unrealengine.com/4.26/en-US/BlueprintAPI/Spline/GetLocationatDistanceAlongSpline/ and update character position.
@@UnrealTefel thank you so much for the reply! Okay, I’m on the right track then. I had sent an email too, so thank you. I’m struggling with where exactly to put this as well as which nodes to utilize though. I tried casting to the first person character to set the location, but that’s not compiling correctly.
Maybe create a tut for layer blend and adding layers a bit more advanced for the landscape its pretty basic tut but i think a lot of people will watch it and there is none of them out there for this specific thing
Can you tell us how did you manage to make the player Grind on the rail / spline ? Thanks in advance.
How is this different from just adding spline from landscape mode under manage or just from add menu > spline, top of ue UI ?
Would be nice if you actually showed us how to add the character to the spline like previewed at the start and end of the video....
for those confused why something is odd and not working, don't use the scale tool at all (R) and use Alt at the end point to add points.
8:59 SSX TRICKY! 😜
How can i make a little overlap? With some mesh it would be nice if the second one spawned a little back not on the very end so it would be overlapped by the first one. Without overlap the mesh that i wanna use with spline looks like it's not connected properly. .
But when I set an onclicked event(Spline/actor) in blueprint， it is not working! why?
Mine doesn't have the Attach to Component box, it's only the Actor and Component to Component. Why?
I suggest using a non-mechanical keyboard while recording videos
Are you from poland? because you have polish accent
3:00 but what if the "Set Forward Axis" node is no longer called that or no longer exists? I can't find the node... I'm searching for it, in Construction Script...
Ok, and how do something like this in even graph in game not in constructor?
Great tutorial, 10/10. Some people use spline component to make rivers also and I will try this. As you said, it's one of the most important components on UE4. Very useful.
Dude i am new at this but i think your videos will make my life much more easier.
Thanks a lot.
Awesome work man. Keep it up.
awesome videos man! I would suggest a 1vs1 local fighter tutorial! :)
10/10
can give us the source where do you get this road,trainrail ?
even if its set to static i can not bake lights on to it. what do i need to do to get that?
That was a really useful and quick tutorial.
Tried this in 4.19 and it just doesn't seem to work. Dragging out doesn't extend the mesh for me. I can create the spline points fine, but there are no meshes on anything except for the fist point, and the mesh can't even be extended. Been through the tutorial numerous times now to see where I may have made a mistake and am struggling to find it.
possible you made a "spline mesh" the root instead of a "spline"?
Worked for me on 4.20.
works just fine in 4.19
How to make this spline system in runtime.
There's an scary sound effect at 7:57...just saying, it's kinda fun to replay it.
Ah haha it's standard UE4 sound when you are stopping the game :D
Cheers Tefel, nice and concise tutorial.
where can i get pipe meshes for free?
Hey Mate, this is the best and quickest tuorial ever to make road or anything. I just have a problem with curves. When i build a road ino curve the mesh will look wired. Do you have discord we can talk juts 5 min ? I have added more splines to make the curve more smooth, but the mesh dosent fit and at the end after the curve the mesh gets bigger and wider. please help me, thakns i sub ! +1 what did i wrong, ciao
Hey thanks, of course there is official Discord of our community you can join: discord.com/invite/SQ6JEkQ
Pretty cool stuff, thanks a lot !
How did the character moved on spline ? I mean by itself ? m working on vry basic traffic AI
You need to calculate distance along the spline, then simply read location along the spline and set it to the character.
thanx ... i'll try that !
Please make this in runtime please
Thanks!
THIS IS WAY OUTDATED
How can I resolve the problem due to the dynamic cast shadow of the spline (Which doesn't exist)? The build give me this error:

Nice Video, There are quite a few Tut like this out there for Spline Meshes but none of them seems to explain how to make them Work ingame. Im looking for a Tutorial that show how to make them work ingame :/ (I want the player to be able to define where to place the spline and edit the spline points but not in a dev kit , ingame )Anyone can help me or does know a tutorial that can?
Thanks for the tutorial. Powerful technique which could save days of work. Subbed.
TO so much!!!, This worked great, and you used hardly any promote to variable compared to others, therefore this BP was much faster and easier to do and grasp. Worked like a charm. :_))))happy dance.
Ok so I followed everything to the letter and all I get is the white spline line where my object should be... Anyone care to comment?? I would love to hear something. Using 4.20.3.
This tutorial is very well made! thank you very much!
I run the Version 4.10.4
They deleted the location for the Forward Axis which you changed to Z. I cannot find this option. Please help me everything works only the direction is incorrect please help.
awesome :D. sooo useful :)
This is created all sorts of problems. My model is coming in the wrong direction and squished. when it extending it just breaks. I am spending more time scrumming through this video to check my steps because of how fast it was slowing down is always better. Just not 40 mins long. There is definitely a sweet spot for this.
all this while i thought only houdini can do this!!!!!!! MIND BLOWN!
wont work on unreal 5
This video was simply amazing. Short, sweet, and to the point! Great tutorial :)
How about turn left? Did the mesh flip down into ground? I used blueprint like this when I turn big angle mesh will flip///
Did anyone get Scale and Rotate to work for spline components?
Sometimes, I want to vary the size and twist the mesh.
Nice Tut! How would you add diff Static Meshes for turns/angles/corners?
I recreated this in my UE4... but for some reason when I rotate one segment (last segment) It rotates all segments.
If you select whole mesh it will rotate mesh, but when select second time - just one point it will rotate only spline point. There are point (cubes) across the spline.
Unreal Tefel Yes, I know about dots. The thing is, when i rotate one dot It rotates the rest as well
How to create a spline mesh? That's the only point i'm struggling with right now....
How did you make actor move along (follow) the spline?
You have to check position along the spline and update it on tick or smth.
It's possible that I will do tutorial about it in the near future.
Thanks a lot! if you make that tutorial would be very very useful
This is what I´m traying to make streamable.com/uoavo
Please make a tutorial for a light which should glow in multiple Colors with few delays .
Thanks a lot for this GOLD tutorial ! BUT i have a question please guys : How to make the roads not square for the turns ?
Because when i try to make a turn, the road are square, i have right angles :s
can someone tell me where he got the pipe mesh from? ive been looking at the ue4 website and other youtube videos but i cant find it.
Hey , just a little question why the X axis for rotation don't work ? Cause i want to do a roll with my spline
I have a question that I want to ask. Is it possible to make it so that the player can adjust a spline component while the game is running? If it is possible how do you do it?
Hi Tefel ! :D
These days, I'm developing a 3D action game with the Unreal Engine, but I'm having a problem with the fight system. I would like to ensure that each movement of the mouse (joystick, or even mushroom of a controller) is linked to a specific fight animation.
Let me explain : Let's say that by pressing F, the "combat mode" is activated, and that each movement of the mouse corresponds to a particular animation.
For example, if the mouse has a rectilinear motion, the character will execute a "direct" punch.
If the mouse has a curved trajectory, the character will execute a hook.
If the mouse describes a perfect circle, the character will perform an aerial circular kick.
Finally, if the mouse goes towards "the back", the character executes an elbow strike turned, etc ...
First, I thought of using an IK system with an animation adaptation, according to the directions taken by the capsules (which are moved by the mouse or the joystick) relative to the hands of the character, but it seems very complicated, and I doubt that this is the most relevant method ...
Do you have specific tutorials to advise me? Blueprint, C ++ does not matter, the objective is to make this game more immersive to the 3rd person.
It seems to be very difficult to programm it or to build it with blueprints, so I ask a pro ;) Thank you in advance
ps : Sorry for my bad english, I'm french.
awesome tutorial, when i had to learn it i watched Epic's tutorial that was like 40 minutes, this is short and spot on, good job, also as an idea : you could make another one about how to interact with splines, and by that i mean something like your train example, i had some annoying problems with rotation and stuff
anyway, good job on the tutorial
Thanks! Yeah this is a very good idea. I have 2nd series "tutorials" where I do longer stuff about 20-30 minutes so I can just make the train tutorial.
I try to keep every guide as short as possible, explaining everything about one case and not being too boring
+Unreal Tefel you are doing a really great job, keep it up and good luck! :)
hello great video btw, but i want to make the character follow the spline when on. But he does not explaine it in the video can someone help me on that? and i have 0 background on programming thanks in advance
I cant see variables in details, there is no "default" tab. Any1 has idea why?
Hey, where did you find that rail mesh? :) I tried to make my own, but it's not working as yours is.
Create a Simple Spline Escalator system how i shoud do ?
Thankss
You're welcome!
is there a way to split splines? so if I have a spline with 3 points and my player collides with it the split splits down the middle (kind of like a finish line rope).
Can you make a Tony Hawk Pro Slater game using these?
How about roads that cars have to follow?
i would like to ask you sir on how to make a spline tube where you can run your actor inside it without glitch.? i wish you would create a tutorial on how to do it. :)
Great video, thank you.
I noticed there is a "Get Location and Tangent at Spline Point" node, that can make the graph just a little simpler.
What would you do if you wanted to make a rope that had a knot on each end and look like one piece in the middle section.
How to create dynamic gravity?? For objects??
thanks man
OMG, Thank you!!!! 👏👏👏👏👏👏👏👏
Awesome tutorial,is it possible to ass a mesh only at the end of the splain,like if it is a cable so it end with a connector?
Great Tutorial.. I created the spline step by step as you showed.. everything works fine... but when i "alt click" at the end on spline point to extend and add another point, that new point comes in between the two points, not in the end.
thank you!
WHY can do my meshes have no COLLISION?!
Edit: 6:12
How would you go about making sure the static mesh object does not scale along the spline?
