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"

Any working multiplayer steam example?

Thanks for giving my question your time

i tried integrating steam (SHIFT + TAB works) and make it multiplayer but i am having issues.. editor crashes when i join a server.

i tried playing in viewport with 2 players, editor filled my RAM and crashed i also treid opening new window editor but whenever i clicked join server, editor hanged and did not respond

i thought i had done something wrong so i downloaded multiplayer shootout , it also crashes whenever i try joining a hosted server. (i am using PIE)

https://www.youtube.com/watch?v=6RlYegIkN0Y so i installed his project and editor crashed after hanging for 10 minutes filling my whole RAM and showed this error:

If you try to use the steam API in two processes simultaneously, the second one will fail to load it (won't show the steam overlay, with errors in the log). So you can't run host and client on the same machine. Also, steam doesn't work PIE, you have to run it Standalone. That said I don't think I've seen it crash in those situations, just not work.

Does the unmodified (non-steam) shootout example crash for you? If so, can you post the logs for server and client?

avatar image Prithvi Singh Jun 26 '16 at 02:33 PM

thanks for the reply,

it does not crash but makes my PC hang(makes it slow and ue4 stops responding as long as its open) so i have to force close it. (my PC is only 4GB RAM, but no project except open world demo , and if kept too much foliage have crashed till now) i will keep that open to see if crashes/runs afterwards (kept it open for 20 minutes before), i can open shootout example in PIE right? or i need standalone for that too? should i involve a laptop in this process?(i am clueless on multiplayer stuff whether its steam or LAN).

thanks in advance!

avatar image chrismcr Jun 26 '16 at 02:57 PM

Yeah shootout should be fine in PIE. Hang makes me think it's running out of memory - is there a lot of disk activity? Epic recommend 8GB for UE4 apparently (and 24 for the kite demo in editor!).

Are you running two instances of shootout PIE (i.e. setting number of players to 2 in the dropdown)? Can you run it PIE with players set to 1? If that runs okay you could try running the other player on another computer on your LAN and see if the reduced memory load helps.

avatar image Prithvi Singh Jun 26 '16 at 03:02 PM

is there any documentation/video for LAN you would recommend (setting up connection and all)?

about disk activity: it stays above 80% when running properly with nothing else open. it filled up when joining server (99%). i always have task manager open to keep an eye for RAM and stay optimized.

avatar image chrismcr Jun 26 '16 at 03:25 PM

I don't know a single source for UE4 network info, I had to read up and experiment a lot. In principle though LAN is really simple, especially since you can do it all in blueprints - on the server you just want to use the Create Session node then Open Level with the 'listen' option. On the client use Find Sessions and Join Session.

Thanks for clearing this out and giving time to this question :)

avatar image Prithvi Singh Jun 26 '16 at 03:09 PM

run fine with one even with 2 players in game but menu level with 2 player have issues.the main level(with game) runs fine with 2 players (in menu i am able to host session , find session , but unable to join, this happens with the one's log posted above as well)

avatar image chrismcr Jun 26 '16 at 03:33 PM

That is really strange. If the unmodified example crashes I am tempted to blame it on running out of RAM, though I'm not certain.

it crashed (shootout) but answerhub isn't letting me post it as a comment (showing - characters left)

if i cannot test it on one PC , how will i know if it will work on multiplayer mode on PC's , is there a way i can test if it works on PC?(multiplayer steam) please type in answer to mark as resolved i guess nothing else can be done.

Thanks for giving this question your time.

The only thing I can suggest is you're running out of RAM. Sorry I couldn't be more helpful!
