UE4 Car Vehicle Wheel with Suspension using Physics in Unreal Engine 4 Tutorial How To

[@jacobell18]

This is the best tutorial I've seen for how to do this. I've spent a lot of time trying to find tutorials for vehicle physics in ue4 and honestly, none have been as good as this. This video was both concise and informative. I really loved how you described what you were doing as you went along. 10/10

[@Lusiogenic]

Thank you! I'm glad the video helped. :)

[@hiddenkonitsu9909]

I agree ! (͡° ͜ʖ ͡°)

[@stevey481516]

Great tutorial, your videos are opening me up to a whole world of cool physics stuff in UE4, really appreciate it !

[@Lusiogenic]

Thanks! There are very few tutorials on physics based assets, I thought I'd fill that gap. Plus, it's really fun to implement stuff with physics. I'm glad my videos have a positive impact. 🙂

[@Kirillnik]

Thank you so much!!! At least I understood the principle. I did it on UE 5. Then it turned out to be a car, but in the beginning I made a simple car according to your lesson. Thanks!

[@JohnDaniels]

At 3:31 I have experienced the exact same thing and remembered you saying this in the video and putting the body on Component 2 fixed the issue with the wobbling wheel. This is interesting that is does that, did you ever figure out why or just put them backwards?

[@itoodear63]

tank you for ur time spent making this video and tank you for teaching me basic things that i haven't found anywhere else

[@VictorMoneratto]

Just found the channel through your reddit post. It's an awesome content and useful for all gamedev! Please keep up the good work.

[@dandroid4488]

This tutorial is amazing! Also, how do you add steering? I tried creating a scene component for every wheel as a joint and i attached the physics and the wheel to it. Then I used the Left/Right input to set the relative Rotation of the Scene component but because the wheel is simulating physics its not working. Do you have a solution for this or another method?

[@JohnDaniels]

Why did you use "Linear Motor" instead of the "Soft Constraint"?

[@Lusiogenic]

I apologize about the siren in the beginning. If it's annoying I'll redo the video.

Thanks for this awesome tutorial! im coming from Unity and was curious if UE4 has Physics joints like unity, and i see it does! thanks for this tutorial! earned a sub!

[@ankapetkova8634]

Great tutorial, but can you teach us how to actually "drive" such vehicle from the Sequencer? That is how to tell it from Sequencer where to go (location) and where to turn (rotate)? I tried almost every thinkable stuff there yet no success. Well, I partially achieved that by adding the Blueprint to the Sequencer and then adding only the body part and moving that part only across my Map + pressing Alt+S for Physics Simulation before playing my sequence so that the wheels follow the body and turns as expected. But then it has some sort off stranger friction that causes it to fly off all of a sudden or flip-flopping randomly by itself like there is very small gravity or if its weight is like few grams or something. So can you show us how to do that, please? UE 4.25.3

[@sajidgame1321]

Thank you my brother , I wish give you thousands of likes , is amazing awesome tutorial

[@JohnDaniels]

Great job 👍🏻. Question, I have always used unreal engines vehicle component which I feel like I don't have a lot of control over and I feel like it's over complex. Do you make your vehicles like in the video all out of blueprint or do you use the vehicle component?

[@JohnDaniels]

Just what I needed, thank you 👍🏻

[@jonedwards3827]

Excellent tutorial, given me great starting point for further work. I would suggest you might consider applying for an Epic Mega Grant. Might take a while to get but definitely a worthwhile candidate

[@Ahmadnaweed786]

great, worked well for me but there something more. I tried to rig the break Kaliper but couldn't. the Kaliper is attached to the wheel so it moves with it but doesn't rotate with the wheel. How can I do that?

[@amirshokuhi]

hi andre i found a serious problem in Physics Constraint , it's just work in first location ! i have used floating pawn movement and i have seen mesh doesn't move but phys cons move with pawn so i had to use an assistance mesh as component 1 in phys cons , that works but pawn movement doesn't consider collision 😁 how can i use pawn movement and phys cons together? Thank you

[@810Sydney]

Nice Tutorial. Is it possible to manage vehicle pawn based on this method ? I mean, instead of create a bone hierarchy in a DCC (like 3ds max/Maya/Blender) and export them to Unreal to have a PhysicsAsset, I was wondering if by exporting just statics meshes and manage them, by using what you in your video, should get better ? Any Idea ?

If I wanted to make my own model to be used as the flat rectangle you have, how would I do this? Also when I run my third person BP into this vehicle, the wheels fall off, how do I fix? EDIT: For some reason my WheelAxis Yaw was rotated 90 degrees, all is well !

You have a trolley with four wheels that turns automatically when pushed by an external force and turns automatically depending on the direction of the push, and you can do a video of that, and you'll get a good one

[@ronnieochero]

Hi, would the physics applied to this car work if for instance your character jumped on top of the car? would it still react accordingly with the suspension/damper or would that need to be done in a different way?

[@shanekruger9412]

love your tutorials! was wondering using the method of the linear motors to control a hydraulic cylinder with input keys, is this possible? or is there better ways of doing it to get realistic physics from it?

[@Lusiogenic]

Yeah, you could use that with a linear drive. Using the keys events you can modify the drive target location, then the constrained component will "go" to that location smoothly depending on the settings of the linear drive.

[@chandlerh2511]

Wonderful video. Thank you so much. I did everything exactly as you showed, but my plane jumps on wheels and the wheels themselves jump and tremble too. What could be the problem?

You peobably have to make the wheela have larger mass. Either that or have a look at where the origin of the physics constraint is. Try inverting the order of the affected components on the physics constraints.

awesome, i hope you cover how to rotate the front wheel with physics contrains as you have in this tutorial.

[@naserharbi]

It took me 6 hours to figure that out! I will gladly share the info on how to do it. going for breakfast now and be back later. key element is to use the Angular Motor by checking Swing (Drives) and add the value of the Turn Rate in the correct Axis for the Target Velocity and add value for Strength. Start with small numbers first to get a feeling on how these values work. Linear Limits all locked. Angular Limits only either Swing1 motion is Free or Swing2. I couldn't make Twist Motion work but I will work on it some more. Hope this is helpful. Let me know if you need more info. Good luck

[@AlFredo-sx2yy]

hey i hope you can give me a hand please! Im trying to make a game where you can attach components to your vehicle. I managed to make the wheel work on its own with the physics constraint (the setup is a wheel with a flat plate on top and you attach the plate to the vehicle), but the moment i attach the wheel bp to the vehicle bp, the wheel falls down, as if the physics constraint had been disabled or lost. The wheel does rotate freely which means that the constraint is not acting, what could be the problem?

[@ahmethakanarslan3893]

what is your gamemode

[@TomatoWithARifle]

How would I add steering and power it with this method?

[@loverschoice885]

i have tried using this to another tutorial, a biplane tutorial, all i wanted was to use this on the plane so i could land, but, when i add this to the biplane bp, inflight it gets torn off the plane as soon as i pie it. Any recomendations? What to look at?

[@Lusiogenic]

Hard to say without seeing your setup. But from what you're telling me, it could either be that you're somehow re-initializing the constraints and so it's breaks off. Or, you have set it to breakable. You should concentrate your analysis on the constraint that gives way or breaks. A short video would help a lot.

[@loverschoice885]

@@Lusiogenic Thanks a lot for the feedback. Yeah, i will, i had a hdd crash and the project sadly is gone now. But iam remaking the plane again. The tutorial for hte biplane creates its custom physics, so i dont know that could interfere with the constraints. It really makes u feel dumb when its just 2 wheels the whole problem contains aswell. Takes longer to solve having two functioning wheels then creating a flying plane with missiles an guns :P I will remake it anyway, and get back to you with a clip. Now ill know to look especially at the contrainsts so ill do some more digging on that aswell.

[@BarakaGameDev]

[@Lusiogenic]

Make sure that the ratio betwewnd the masses of the wheels and the body is not too high. I wouldn't recommend more than 10 times. If not, look into adding physics substepping.

[@llamamehoju]

If your vehicle stucks floating, yo have to enable physics for the wheels and the body in the object details

[@Thunder_Owl]

I am wondering, if I will have AI system for such "car", with turns, would it be workable just making fake wheels axis turns (rotations), meaning two of wheels turning a bit on "Z" axis while in fact it will be car body that gets actor rotation, and wheels just "play along"... I hope I managed to describe my thought :)

[@Lusiogenic]

Yes, you can set the wheels to stay into a certain position using the Set Linear Target Position and Set Angular Target Rotation. Well, if you set the position of the wheels and make them turn with Add Torque or Set Angular Target Velocity, the car should work as a normal car, without any hacks. I haven't yet done this, so it's still theoretical. But, if you want, you can turn the wheels and body at the same time. Not sure if just turning the body would work..

[@Thunder_Owl]

@@Lusiogenic Hello! Little hope you still might read here, but I will try. Today I felt need to continue experiments with this, trying to make turning in realtime. After several hours, no luck. I am not finding is it possible at all to turn anything in such constraints constructs. If I set constraint with wheel "child" at angle before run - yes, it is fine (I test on slope). But, I have not yet found a way to steer at runtime. Anyone knows maybe? Maybe it is simply impossible with such setup? Thank You... Edit: I had some small success to set wheels rotations via "set angular target" for axis constraint, so it starts to drive / turn tank-like (ok for me), but... it does that only one time. Am I missing some aspect, or this isn't actually workable? Thank You... EDIT2 - hmm with more experiments I think I am getting some needed results on controls...

Hi lusiogenic, how i can rotate the wheels with this system?

[@Lusiogenic]

Yes, you can either directly AddTorque to them each frame or set up an angular motor in the PC_WheelAxis and set the desired Target Velocity. I will do a complete car tutorial with acceleration and steering, but haven't yet got around to it. Working on something else at the moment.

[@artbyal2409]

so i found a solution i really wanna use, problem is, my vehicle is a flying vehicle, ive added the wheels beneath the vehicle mesh, i disabled the disable collisions in the pc axis components. But now my flying vehicle is rotating uncontrollably in the air. Theres some kind of conflict. My goal is to use the velocity and torque from the flying vehicle and let you wheel tutorial only let it roll on planar surfaces. the vehicle spins in its roll and yaw. Any feedback would be appriciated on this. from anyone really. :)

Without knowing more on your setup, it's hard to figure out what's wrong. If you want to make a hovering vehicle, I would go with line traces and thrusters.

Mine isn't so much falling through the ground, more that it ends up on its side with 1 or 2 wheels stuck in the ground.
