Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Multiplayer - Jumpy Movement Replication on Client

Hi, I'm trying to wrap my head around a strange issue with multiplayer movement replication that only happens on client side.

Everything is fine until the player character picks up a weapon (which attaches to a socket near the waist) and all hell breaks loose with choppy jumping movements, as if the player's location is constantly being overridden.

Movement is properly being replicated to all clients (along with certain variables like IsSprinting, IsDodging, IsCrouching etc). UseControllerRotation is checked, OrientRotationToMovement is unchecked.

  • With listen server, the server sees no jittering, but the client does.

  • With dedicated server (which is my final goal), both clients see the jittering movements

Here is an example gif of the behaviour:


Any help would be appreciated, I can provide additional screenshots if necessary

Have you tried disabling the collision for the weapon when you pick it up? Perhaps the movement is jittering because your character collides with your sword.

Yes, after the weapon is spawned and attached to the socket, its collision is turned off.

Nevermind, changing the collision presets to IgnoreOnlyPawn seemed to be the way to go. No more jittering now!
