Build interactive first-person and narrative games with visual FlowGraphs,
saveable state, menus, dialogue, audio, microphone stealth, NPC helpers,
weather, effects, and editable C# source.Tested with:- Unity 6; tested with Unity `6000.0.38f1`.- Universal Render Pipeline `17.0.1`.- Input System `1.8.1`.- AI Navigation `2.0.0`.- Timeline `1.8.6`.- UGUI / TextMeshPro `2.0.0`.- Vehicles built-in module `1.0.0`.- Windows editor and standalone player are the tested release targets.- FMOD for Unity is optional and is not included.EasyFlow is an editor-first Unity 6 URP framework for building interactivefirst-person, horror, walking-simulator, and narrative game systems withoutrewriting the same project foundation.Connect behaviour visually in the FlowGraph editor or use compact ActionSequences for linear logic. Make scene objects interactable, branch on savedvariables, open locked doors with inventory items, play dialogue, switch audioor weather, trigger a Timeline, and extend the system with readable C# modules.- Dialogue- Documentation- Weather- Day/Night- First Person with Flashlight- Menu builder- Flow-Nodes-Actionsystem- Inventory- Throw Items- Drive Car- Footsteps- Audio Effects- Visual Effects (VHS/Sepia/etc)- Stay Quiet Event- Custom Events- Demo Scene- Demo Game- And much more...Create Games (slight focus on Story-Telling or Horror-Games) really fast and without any programmingVisual logic and interaction- FlowGraph editor with zoom, pan, movable nodes, multiple incoming/outgoinglinks, editable parameters, connection removal, and node inspector.- Action Sequences for fast linear behaviour without creating a graph.- Interactables, triggers, reusable timers, conditions, parallel branches, andUnityEvent integration.- SceneBinding IDs let reusable assets address scene objects without fragiledirect scene references.Player, inventory, and persistence- First-person controller helpers, camera restrictions, flashlight, carrying,visible held objects, and optional throwing.- Inventory items, pickup objects, required-key doors, and persistent worldvariables.- Save slots for player position, inventory, game state, scene state, and menuContinue/Load availability.- Keyboard/mouse and gamepad navigation.Menus, localization, and dialogue- Main-menu builder with New Game, Continue, Load, Settings, and Exit.- Pause menu with time freeze, menu BGM, resume-safe gameplay audio, andplaceholder Map/Inventory tabs.- Audio, Graphics, Language, Input, and Accessibility settings.- English-default localization tools with German-ready samples.- Dialogue editor, character switching, localized dialogue, optional voiceclips, and quick one-line messages.Audio and microphone systems- Central audio registry for SFX, single-channel looping BGM with crossfades,and dialogue.- Master, SFX, BGM, and Dialogue mixer routing with independent menu levels.- Output/input device selection and optional five-second microphonecalibration.- Audio Quiet challenges with an interpolated vertical green/yellow/red meter,threshold failure, timers, and success/failure actions.- Variable footstep surfaces, audio-effect areas, reverb/radio/underwaterfilters, and BGM switch areas.- Optional FMOD event, snapshot, and parameter bridges.

OpenAI imagegeneration was used to create the optional RelayStationBackdrop.png samplebackdrop. The generated and assisted material was reviewed, integrated, andtested in Unity. EasyFlow makes no generative-AI calls at runtime and requires noAI service, account, or network connection.
