The lobby could stage a room but the launched mission never fed the members.
BTLocalConsole_InstallNetworkMission (btl4console.cpp) makes the host play the
arcade console in-process over the NetTransport seam (Winsock TCP or Steam SDR):
- connect to each member's console channel (ip[:port] from BT412HOSTPODS);
- feed each the chunked egg (NetworkManager::ReceiveEggFileMessage, \n->NUL
wire image like tools/btconsole.py), resending until it ACKs;
- poll member state (StateQueryMessage); when the whole mesh is staged at
WaitingForLaunch, dispatch RunMission to every member + locally at once;
- StopMission at expiry (members first, then self after a short grace);
- scores are BT's kills/deaths snapshotted from the *meshed* roster at the
stop -- no EndMission wire intake (that flow is a BT stub; the mesh already
put every pilot in the host's roster). The owner's own pod is fed locally
via L4NetworkManager::FeedLocalEgg.
Engine change (ported 1:1 from RP412): gConsoleMarshalsLaunch (APPMGR.h/.cpp) +
the `!gConsoleMarshalsLaunch &&` guard in APP.cpp's WaitingForLaunch self-launch.
The owner has no console connection to itself, so without this it would
self-launch before the mesh staged and never send the coordinated RunMission.
Default False = stock behavior; solo boot un-regressed.
WinMain host path (btl4main.cpp) now honors BT412HOSTPODS (+BT412HOSTPORT) for
the lobby host AND a classic-LAN host: SetNetworkCommonFlatAddress +
InstallNetworkMission, falling back to a solo marshal if no member is reachable.
Verified (loopback): two `btl4.exe -net` pods fed by tools/btconsole.py reach
"All connections completed!" and run after the engine change -- the exact
protocol + launch handshake the marshal uses. Both gates build+link; the
Release dist boots and the Steam transport comes up. The live multi-machine
Steam mission (FakeIP mesh + pilot-slot matching) is untestable here -- see the
new docs/STEAM-3-MACHINE-TEST.md. Dist README updated: multiplayer is now
"newly implemented, please test" rather than deferred.

MULTIPLAYER - please read
|
|
-------------------------
|
|
This build is for testing STEAM multiplayer end to end.
|
|
|
|
Steam lobby + networked mission. With Steam running and BT412STEAM=1, the
|
|
menu shows HOST STEAM MISSION and JOIN STEAM MISSION. HOST creates a room;
|
|
JOIN finds and enters one. Everyone in the room sees the member list (name,
|
|
mech, color) and exchanges their FakeIP + loadout. The host presses LAUNCH
|
|
MISSION: it then acts as the in-process console -- it feeds every member the
|
|
mission over the wire, holds the whole mesh until all are staged, launches
|
|
them together, and stops the mission at the chosen length. The member pods
|
|
mesh with the host and each other; kills/deaths are collected and the same
|
|
results screen shows on every machine.
|
|
-> Test: two (or three) machines, each signed into a DIFFERENT Steam
|
|
account, all running this build. Confirm they find each other in the
|
|
room, the launch fires, everyone drops into the SAME mission and can
|
|
see/fight each other, and results show everywhere.
|
|
-> The host->member mission feed is NEWLY IMPLEMENTED. The console
|
|
protocol + launch handshake are loopback-verified here, but the full
|
|
multi-machine Steam mesh has not been lab-tested. If a member does not
|
|
drop in, grab btl4.log from each machine (grep [marshal], [frontend],
|
|
net-tx / net-rx) so it can be diagnosed.
|
|
|
|
CLASSIC MULTIPLAYER (no Steam, proven): the external console emulator feeding
|
|
-net pods over TCP. Needs Python 3.
|
|
Set BT412STEAM=0 in environ.ini, then:
|
|
Machine A: btl4.exe -egg MP.EGG -net 1501
|
|
Machine B: btl4.exe -egg MP.EGG -net 1601
|
|
Feeder: python tools\btconsole.py MP.EGG <A_ip>:1501 <B_ip>:1601
|
|
Drive, fire, cross-pod kills and respawn all replicate on this path.
|
|
|
|
Steam notes (for the lobby test):
|
|
- steam_appid.txt (480 = Valve's Spacewar test app) ships beside the exe so
|
|
Steam init works before the title has its own AppID. Keep it for testing.
|
|
- Use a DIFFERENT Steam account per machine (Steam allows one running game
|
|
per account). Disable Steam Input for app 480 if the controller misbehaves.
|
|
- If Steam is not running, the game logs the reason and stays on TCP.
|
|
|
|
Logs: the game writes btl4.log beside the exe (set BT_LOG to rename). Grep it
|
|
for [frontend], [marshal], [steam], net-tx / net-rx when reporting an issue.
