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"

Server-/Client-Simulating in Level Blueprint

Hello everybody,

I'm about to dig up an old project and get back to work on it. Now, after a long abstinence from the Unreal Engine, I try to familiarize myself again, fix a few bugs and update the project to the latest engine version.

The original project was created with UE 4.6 and I try to update iteratively to the next higher version until I reach 4.19.

Now to my actual problem. It's a multiplayer game and I just can't find a way to switch debug mode or simulating between server and client in the level blueprint. There is also no debug filter in the level blueprint, as in other blueprints. I have searched a lot, but found no answer.

In the 4.6 project "Server - Simulating" is displayed: UE4.6_LevelBlueprint_Server-Simulating

And in the 4.8 project "Client - Simulating" is displayed: UE4.8_LevelBlueprint_Client-Simulatingt

How can I set whether exactly the server or the client is displayed during simulation?

Product Version: UE older version

I get it. The solution to my problem is described in the Gameplay Guide under the section Multiplayer Options. The Use Single Process "spawns multiple player windows in a single instance of Unreal Engine 4. This will load much faster, but has potential to have more issues. When this is unchecked, additional options become available."

The Option Editor Multiplayer Mode let you choose the NetMode to use for Play In Editor (Play Offline, Play As Listen Server or Play As Client). Depending on the selection, the simulation is executed as server or client.

A very useful option would be the possibility to switch between server and client in the level blueprint on the fly, just like in the other blueprints.
