Amazing work evernewjoy. A big thanks from me for all these awesome tutorials. I've requested to make this thread sticky. Do you take tutorial requests? Because I do have a few things that i'd love to see as a tutorial.

[evernewjoy]

I'd be happy to know what your tutorial requests are!

I make tutorials based on things I am learning myself for my game but if you have a request that I feel I can tackle it could be fun for me

Rama's Physics-Based Retractable Tether / Grapple Hook for Skeletal Mesh Pawns
Move pawns around as if with RB_Constraints and Rigid Body Physics

Dear Community,

Here I present to you a fully functional physics tether system for skeletal mesh actors!

See the Video Demoing the Complete Code I am providnig you with below!

This code is:

-low level simple functions for unreal engine to handle

-optimized for variable memory access, I use multiple-purpose global variables to minimize creation/destruction of variables, and to enable the actual tether functionality to be optimized

-easy on replication, as I am not using any custom animations or Rigid Body / ragdoll states

-still looks really good and is easy to control in-game to make for awesome fun gameplay

-works regardless of framerate, see the DeltaTimeBoostMultiplier for details, even if frame rate fluctuates the beam is kept in same location as the pawn's skeletal mesh socket.

-This is all my own original code after many hours, weeks of my own efforts over time, I wrote it all from scratch (the code here took me only a few hours to write, but the learning that went into this happened over several weeks.
