I spent so much time to getting understanding how to make something like that. - YouTube
- Physics Handle is not working correctly. i’ve got some glitches everytime.
2)Attach to Actor is not working correctly, cuz i need a collision detection, but also i can’t fix that on this way
Please! may be someone knows how to do that or can give advice? All i need it’s just moving object by my character on XY directions with consider collision!
Thank you and sorry for my English
Well im not 100% correct but I believe little nightmares uses a plug-in called iKinema. You can check out this link

not really helpful but just leaving it here 
I’ve done it by creating physics constraints in the past.
I would create a custom class of some description that can be interacted with and then whenever the grab input is fired it does a trace to see if any of these classes are in range. If found, then spawn a physics constraint that attaches the actor to the physics actor.
Here is a quick and dirty example I just whipped up, needs a lot of polish to get it to behave like in Little Nightmares but it behaves the same way from a physics standpoint.
If it’s not clear let me know and I’ll try and go into a bit more detail.
