## Instructions - Build in UEFN (PC editor) + Fortnite Creator Portal; version islands, use revision control (URC) with check-in comments. - Learn Verse basics: `Print`, `Sleep`, `spawn`, `event`, weak maps, `creative_device` classes; keep Verse for logic, devices for content. - Compose gameplay with devices/props: Player Spawner, Item Spawner, Guard Spawner, Timer, Tracker, HUD Message, barriers. - Tune island settings: max players 2-100, teams 1-4, respawn 3s, matchmaking region auto, permissions (building/editing off for minigames). - Playtest rigorously: Start Game solo, multiplayer via Session (2+ clients), memory check <100k units, perf on Switch/mobile. - Design for Discovery: thumbnail 1920x1080 punchy, title 20 chars + SEO tags, trailer 15s hook, update on Thursdays. - Follow publishing checklist: no copyrighted assets, ESRB questionnaire honest, Island Code test link, moderation 24-72h window. - Monetize via Engagement Payouts: track CCU + retention (D1/D7), playtime minutes, favorited rate; iterate weekly. - Use Verse persistence (`persistent` vars) for stats/loadouts; respect privacy (no PII storage, Epic account IDs only). - Optimize: HLOD + streaming, cull small props, reuse galleries, avoid 100+ Verse tick loops; use `Sleep(0.0)` yields. - Market: TikTok/Shorts clips, Creator Code in description, collab with 2-3 mid creators for launch spike. - Track analytics in Creator Portal (plays, avg session, quits); kill/update maps <2min avg session within 2 weeks. ## Examples - Example 1 — Zone Wars: 16-player spawners, storm controller device phases 60s, Tracker kills -> win, HUD leaderboard Verse. - Example 2 — Tycoon: button device grants coins via Verse bank, Item Spawner unlocks at thresholds, persistence saves tycoon level. - Example 3 — Horror: mutator night vision, sequencer jumpscare, Tracker time survived, no-build settings + 1 life. ## Workflows 1. Concept: pick proven genre (BoxFight/Tycoon/Horror), block layout with primitives, set teams/spawns/settings. 2. Build: place devices + galleries, write Verse game logic (score/timer), add audio/VFX, memory audit. 3. Test: solo + 4-player session, Switch perf check, fix spawns/storm edge cases, record trailer clips. 4. Publish: thumbnail/title/tags, ESRB form, submit, share Island Code, launch with 3 Shorts + creator lobby. 5. Grow: read analytics (retention drop points), weekly update (new weapons/area), push Discovery via favorites + playtime. ## Templates ### Verse snippet — Tracker + win ```verse using { /Fortnite.com/Devices } using { /Verse.org/Simulation } game_manager := class(creative_device): @editable Tracker : tracker_device = tracker_device{} @editable EndGame : end_game_device = end_game_device{} OnBegin():void= Tracker.CompletedEvent.Subscribe(OnTracked) OnTracked(Agent : agent):void= if (P := player[Agent]): EndGame.Activate(P) Print("Winner!") ``` ### Island settings preset ``` MaxPlayers=16 Teams=2 Respawn=On(3s) Building=Off FallDamage=Off Storm Phases=5 (Wait60/Shrink30) LootPool=Chapter5 Ranked Memory: 78,400/100,000 Perf: Switch 60fps locked ``` ### Publishing checklist ``` [ ] No IP-infringing art/audio [ ] Thumbnail 1920x1080 [ ] Title+tags SEO [ ] ESRB honest [ ] 2+ multiplayer tests [ ] Memory <100k [ ] Code tested [ ] Description + Creator Code [ ] Trailer 15s [ ] Moderation buffer 72h ``` ## Tools - UEFN editor, Verse VS Code extension, Fortnite Creator Portal, URC revision control. - Art galleries (Epic curated), Sketchfab CC0, CapCut for trailers, Creator Analytics dashboard. - Discord playtest groups, Alt accounts for MP testing, Switch + Android perf devices. ## Advanced - Write modular Verse: `/Game/Systems/score.verse`, interfaces for modes, unit-test logic with simulated agents. - Boost payouts: daily quests (Verse persistence), 10+ min sessions via progression, requeue button + party-friendly spawns. - Handle live-ops: feature flag via editable balance vars, hotfix without downtime, A/B storm timings. ## Documentation - https://dev.epicgames.com/documentation/en-us/uefn - https://dev.epicgames.com/documentation/en-us/uefn/verse-language-reference - https://www.fortnite.com/news?tag=uefn - https://dev.epicgames.com/documentation/en-us/uefn/publish-from-uefn
