Summary0002753: Floating items in multiplayer
DescriptionHi, I've noticed that there are floating items now in the latest 3.0 beta in multiplayer but not in single player. This happens if the item is too close to a platform.
Steps To ReproduceHow item is placed in doombuilder'http://i.imgur.com/Oc08il1.jpg [^]'
How item appears in singleplayer (latest 3.0 beta)'http://i.imgur.com/2baljPq.png [^]'
How item appears in multiplayer (latest 3.0 beta)'http://i.imgur.com/vio6LgE.png [^]'
How item appears in gzdoom'http://i.imgur.com/ysTcjHF.png [^]'

As you can see there is a strange desync. I have attached the demo pk3 to test.

The problem is related to the network desyncs described in ticket 0000408.

Yep. Though it should be noted that this does not occur in 2.1.2 multiplayer.

Edit: Looks like it also happens with vanilla items such as medkits.

I think it's indirectly caused by one of the ZDoom fixes mentioned in the ticket, which are now present in zandronum 3.0.

0000408:0015072 should fix this bug.

Any chance a beta-build can get released with the fix? My mod for 3.0 needs this.

This needs to be tested and approved by Torr.

From testing the build watakid posted here:'http://zandronum.com/tracker/view.php?id=408 [^]'

It appears to have fixed the issue on the test wad and all out war.

I added Edward-san's patch for +NOGRAVITY things, so this should be fix in 3.0 now.

Tested with 3.0-160814 and the item was correctly positioned online even after map resets.
