This is extremely helpful, thank you! There should definitely be something like this video in the UE4 docs showing which axes to lock to make these real-world joints out of the engine's generic constraint.
THx for tuto. 19:30 in order to make it Twist or swing like you would exepect, you should change the oriemtation of your constraint acording to your objects
Why did u stop man? keep going, Epic is now supporting youtubers through mega grants as well. You were in the right way, ur content is quality, just keep it up.
Hi there Lusiogenic, great tutorial series, love it! With all physics, no matter what we try to lock/dampen/constraint, we are always able to move along the locked axis if we push the object too far. Is there a way to completely lock the other axes that should not move/rotate? The obvious "lock" in the physics asset is not doing the trick, nor all the constraints we set.
Thank you! I have worked with Unity a long time ago, but I can't say I'll be revisiting it. I'm guessing the constraints should function in a very similar manner.
You explained things very clearly, but for some reason it does not work in VR without an intermediary. A stick or bullet, or something. If I se it up the way you have it, and shoot it, or hit it with a stick, it reacts as expected. If I grab anything, it has a different affect. For instance, I have a lever that has 2 parts. A base (that I want locked) and a stick, which I want to rotate at the base. If I have Constraints locked in XYZ for Position, on both the Base and the Stick, the stick still pulls away when I grab it. I have to put a value in Inertia Tensor Scale XYZ to get it to lock to the base (not sure why). Can you explain how to make a lever, and have some resistance on the movement?
Question: You have Cube1 and Cube2. If you want to move (through BP) Cube1, how would you do that? Say... you want this thing to move out of the way, after the player has moved the slider. Player slides the handle, and then the whole door moves up, or something. It seems UE4 pulls the objects out of the hirarchy when they are attached to a Physics Constraint, so their original parent's movement has no affect on them.
Thanks by class! Can I download this template? I need this mouse interaction. I try to use the Unreal Template "ContentExamples/Physics" but only the objects in the original template can be moved, my objetcs moves only if I use other object to move him, but the mouse interaction not works.
The lesson is good, I liked it and I tried to follow it. But for some reason my blueprint is not working. I don't understand where I made a mistake! Can you help?
Say, how would I change the direction of a physics object more quickly? Rather then it slowing down by adding force over time is there another way to make the sudden changing of direction quicker but without effecting the added force over time? Not sure if I made that clear but, in this case, I am rotating an object around a central axis using a physics constraint, but I want the changing of direction to be a bit more responsive. Right now, it slowly slows down before changing directions.
Question: how can you animate a robot arm using this ? I have correct motions now, but it's limp/ragdoll. How can I make it rigid, for example, follow a null, and rotate/move in this same position, but way more rigid and only if pressure is applied
I used the linear join concept, to make a landing gear for a spaceship. It is basically a leg that has suspension. Very simple. At first glance it works fine. But doing some tests I discovered a strange error: the landing gear disappears when the ship is oriented in a particular direction. For example, if the nose of the ship is to the east, everything is fine, but if you point it to the south, the landing gear leg (which has the physical constraint) disappears. (?wtf?) Even weirder is that this doesn't happen on the map I have for testing. I have no idea what is happening.
Thanks for the great tutorial. When i make a cabinet with some drawers use physics, i drag the mouse can move the drawer to the far far away, i had set the physice constraint X limit but it is not stop at that position, how to fix this problem?
Hi all. Ive been messing around with this tutorial but I cannot get the objects to interact with the collision boxes set up on the VR pawn. Anyone have an idea how to do this or if its even possible? I can add a grab component but it just grabs the object and allows it to move around freely then snaps back to its original position when I let go. Any help would be appreciated thanks
CAN I USE THIS IN GAME .?? I HAVE A TRAIN .. I WANT TO USE PHYSICS CONSTRAINTS TO MAKE A BASIC ENGINE WHICH WILL MOVE THE TRAIN FORWARD AND BACKWARD ... I AM REALLY NEW 3 MONTHS OLD GAME DEV SOO I DONT REALLY KNOW NOTHING ABOUT UNREAL .. SOO CAN I USE THIS IN MY GAME AND MAKE A TRAIN SYSTEM (ITS GONNA BE BIG 700^2 KM MAP)
I've recently started streaming the development on Twitch. You can ask questions during the live stream and I will do my best to answer them. Make sure to follow me on Twitch to get notified when I go live: www.twitch.tv/lusiogenic

One of the best UE4 physics tutorial I've ever seen.
Thank you, sir.

I agree, physics documentation is very scarce in UE.
Thank you so much! this is one of the important "must learn" unreal tutorials that i have been looking for a long time

Glad you're back! I missed these physics based tutorials.
Thanks man, glad to be back. The last month was extremely busy, couldn't get a tutorial out.
But now I'm back at full speed! :)
Great
Thank you! Your tuts are very good for me. Please keep them.
switching over from unity. this is helping a lot, thank you.

A Brilliant and simple tutorial on how to create and manipulate Physics Constraints. Lusiogenic rocks! :)
Thank U, it is just what I needed for the different joint mechanics and how to set it up

Your explanation of game engine joints are the best I have ever seen. I any chance you could also explain the joints in Unity as well?
Thank you!

Awesome! I m a newbee in UE4, how can you use your mouse to drag the thing?
Is it at all possible to make the motor move the child up and down using input as if it was a rope?
Thank you. Excellent!!!
How can you grab the object in the scene as you do with the mouse click? A Physic handle?

Thank you! You saved me.
What can I do with these constraints? Are they meant to be associated to physical objects (meshes)?
Would you please make tutorials on mechanical build system similar to Scrap Mechanic?
Thanks for the great tutorial. When i make a cabinet with some drawers use physics, i drag the mouse can move the drawer to the far far away, i had set the physice constraint X limit but it is not stop at that position, how to fix this problem?
I'd have to see the setup of you constraint to help you with that. Make sure that the limits of the constraint are set correctly.
Is it possible to have to physics objects move along a spline as in a roller coaster?
can physics simulation be used in caculate Inverse kinematics?

Hi can this be applicable to the VR hands template, thanks in advance
@@stephenhidalgo7608 It should be. I've never worked with VR, though.
Thank you :)
7:30 hinge joint I think
Awesome
Amazing video.
I wish I could subscribe more then one time : )
like without even starting to watch the video .
after the first minute, i am in love
@@amigoface He he :) Thanks a lot, I really appreciate it.
10:26 how to make rdr 2 lantern system
Any chance for a project file boss
Thanks for new physics ! :)
Sorry, but are you Brazilian?
You could make this (and maybe some others) as a learning project(s) downloads....
I will, and it will be available through the Unreal Marketplace. I just have to find the time to do it.
not too expensive, hopefuly
@@Latvian3Dman I think not. I will be consulting with the community in order to find the best price for everyone.
@@Lusiogenic , but, these "diy" series will stay? Or should we hurry video capture all of them... ;)

thanks for the tut.. but you don't explain how you are interacting with it. you are giving you viewers half the story
Please make a boxing bag
Awesome idea! That should be pretty easy. I'll put it on the list.
