Tip jar: your first Server Object
Build a shared tip jar from nothing with only the editor and Blueprints, step by step. Make the Server Object asset with a Total variable and a Tip function, paste its few lines of server code, Generate and Deploy, then add a component to an actor, follow On Total Changed with Print String, call Tip from a key press, and watch two players see the same total rise.
Guild halls and arena lobbies
Two worked Server Object examples in Oakford, using members, access, timers and Can Call - guild halls of five players seated by a registry and followed with From Server Value, and an arena lobby of eight where the leader starts the match, joining closes and a ten-minute timer ends it - with the asset settings, the logic.rs lines and the Blueprint side of each.
Shared boss fight
A worked Server Object example in Oakford - one boss every player hits, with its health kept on the server - covering the structs or the asset's own variables, the asset rows (Readable By, Hit's Callable By, Cooldown and Value Range, a Respawn timer), the logic.rs that refuses hits while it is defeated and respawns it, Deploy, the actor and its Crowdy Server Object component, the Blueprint with typed nodes, two players in Play In Editor, switching the type off and on from Server Compute, and what players see when the boss falls.
