Replication Support

[senfkorn92]

Added character states replication, support for mantling (on static and moving objects), rolling, jumping and landing.

Looks interesting, I will review it asap 👍

Thanks 😃. Forgive me if my syntax is unprofessional or inefficient. Was mainly doing this for the practice. Thanks for your work as well. The codes seem to perfectly translate the blueprint version accurately so reading the code was super easy

Sorry for not responding back, I'm trying to find some free time for review. Probably will have some this weekend :)

A few points;

• Ragdoll root point is not synchronized between clients, causing character position to teleport into somewhere else when quitting from ragdoll mode.
• While running, immediate 90 or 180 degrees turns causing stuttering, because of server trying to correct rotation of the client.
• Rolling causes stuttering on client-side, and also character mostly rolls into incorrect direction
• While aiming with a gun, changing aiming rotation causes stuttering on the aiming character for observer clients.
• Turn in place doesn't work on client-side.

Unfortunately, I can't merge it into master at this state, since it's facing most of the same problems with my v2 implementation.

I'm still following up your work, and it looks much better after latest commit. I will test them later today, and let you know if I face any issue. 👍

I have tested your latest commit, and everything seems like working, except;

• Turn in place still have problems on client-side, you should disable movement replication while character is stationary (so that server won't try to correct rotation of the character), that was only workaround that I can find for this issue.
• While moving, if I enable ragdoll mode, a huge amount of force is applied into character in both server & client. Not a huge issue, but would be better if we can fix it before the merge.

Thank you for the hard work :) If you have trouble with fixing turn in place bug, I can get my hands dirty with your branch in a few days 😄

Thanks so much 😁. I don't think I've fixed every issue that you've presented before though. Some of them being;

• Rolling causes stuttering on client-side, and also character mostly rolls into incorrect direction
• While running, immediate 90 or 180 degrees turns causing stuttering, because of server trying to correct rotation of the client.

While moving, if I enable ragdoll mode, a huge amount of force is applied into character in both server & client. Not a huge issue, but would be better if we can fix it before the merge.

The issue above happens because I'm correcting the client's position to the server. If you'd like, I can fix it by either;

1. Changing it so the server's mesh position corrects to the local client's place instead, I would need to implement a Server RPC of the "TargetRagdollLocation" variable to the server on tick which increases bandwidth usage.
2. Gradually increasing the force of the client side pull which might cause the character to be unnaturally 'pulled back' over time to the server side's location.

I'm considering the second option atm with an if velocity more than threshold statement

[dyanikoglu]

Let me know when you're finished with the PR. After that, I will convert your work into new plugin structure before merging it

[dyanikoglu]

Thank you for that huge contribution, I've merged master into yours and solved all of conflicts, everything seems in order.

From now, for bugs & missing features, I recommend creating new issues & branches for them.
