Multiplayer Game Series (Pt 1 -character)
Part 3 - Create/Join Session
Basic concept in graph:
Rename all menu BP from previous tutorials, make it less confusing:
Ensure Save and load player function properly
Open GameInstance graph Load Profile function
Add a wire below (to store save game object and load correctly each time):
In Check for saved Profile function, add SG player profile set node
Create Multiplayer (MP) menu widget:
Open WB mainmenu widget, add newborder to create a main menu:
Duplicate the widget, name as WB_MpMenu
Revise the Mpmenu widget as follow:
Rename text block 3 as Text_Connectype, Tick the text LAN is variable
Back to MainMenu Widget (I maintain the old mainmenu widget, duplicate a new one)
Change to multiplayer button in text, rename the host button as Btn_MPGame
In Gameinstance, duplicate UIShowmainmenu function, name as UIShowMpMenu
revise as follow by create WB_MpMenu variable, and replace back:
Back to revised mainmenu widget, add click on MPGame button(to show Mp menu and remove mainmenu)
Open MpMenu widget
Change the MainMenu node as follow (same as above)
Connection Type button (to make Connection button work):
Go to Game instance, add variable IsLanConnection
Add function called ChangeConnectionType
Back to MpMenu widget, graph, add new function called SetConnectiontype_Text
Add input variable Is lan connection
Back to Mpmenu event graph, extend event construct nodes ending:
Setup create and join session:
To create multiplayer session:
Go to GameInstance event graph, create custom event name CreateMPSession:
Create session node set 4 max players
To create join session:
Add another custom event called JoinMPSession, add input variable
Node connection (if sucess to join session, will load into lobby menu map)
Set things up in Multiplayer menu:
go to MPMenu widget
For hostGame button:
To disaply finding sever, add new border (Serverlist) in design page, rename both border and scrollbox and make as variables:
Create a new widget called ServerRow,
Set those text as variable, the button makes different color tint pm normal, hovered, and pressed
Go to graph, add 2 variables
Create custom event, add input variable Session Result
(Split node type “-” In Str (i.e. dash), mean search from left side of dash )
Continue for Text Num Players:
(Format Text node need to type {a} / {b} for input a, b options)
For Text Ping:
(Drag from reroute node for “Get Ping in Ms” node)
Add on click on button 34
Back to MpMenu widget, rename the 1st border as border menubutton, set as variable
Back to ServerRow widget graph, finish as
Set Search Game function:
Go to MpMenu widget, add on clicked on Btn_searchGame
Choose border serverlist, set visibility as hidden
Now make a graph to let serverlist only visible when it works, also clear stuffs left in scroll server list when open menu again:
Add variable All server info WB:
Change Search Game text to variable and rename as follow:
drag in graph and continue the graph to clear server info, show searching... text, disable border menu all buttons, etc
Continue to find session (if fail to find):
Go to ServerRow WB, choose WB_MpMenu variable
tick instance editable and expose to spawn
Back to WB Mpmenu graph,
Now the server row widget node can choose asset in WB mp menu section (choose self as reference)
continue
Reset event construct/begin in Mpmenu, to let ppl know the menu is fresh when open up:
Strat from ending of Event Construct node graph in MpMenu
