Build offline solo card games with visual authoring, extensible effects, an in-game deck editor and a complete playable example.Your cards. Your rules. Your world.Everdraft gives Unity developers a reusable foundation for offline solo card battles. Start with a complete playable example, create your own content with visual tools, and extend the framework to fit your game's rules and presentation.Create cards in Card Studio with a live preview, configurable effects, targets and conditions.

Define rewards, upgrades and encounter access in Progression Studio.The runtime includes an in-game deck editor with local saving, optional fan-shaped hands, card-entry animations, hover previews, automatic end turns at zero energy, turn-start checkpoints and clear victory/defeat screens. These presentation features can be configured independently.Extend the combat session with custom effect and status modules, or connect your own interface to ordered battle events. A setup assistant, integration examples and effect diagnostics help you build another game on the same foundation.Signal Break is the included standalone science-fiction example, with original vector card diagrams and three scenes: Signal Break, Behavior Lab and Progression Lab. Developer documentation is in English; player manuals are provided in eight languages.This release is designed for offline solo play against enemies. Online multiplayer, PvP, accounts, shops, booster packs, rankings and cloud saves are not included. The fantasy elf is promotional artwork; the included playable game is Signal Break. No additional Asset Store package is required.See Technical details for verified Unity versions, platform limitations and the validator font warning.PACKAGE CONTENT• Version 1.0.0.• Single import root: Assets/Deckbuilder.• Editable C# source, assembly definitions, editor tools, styles and documentation.• Signal Break example with a 12-card library and two starting loadouts.• Three example scenes: Signal Break, Behavior Lab and Progression Lab.AUTHORING AND INTEGRATION• Card Studio with live preview, configurable effects and visual behaviors.• Enemy Studio with sequences, weighted actions and conditional phases.• Progression Studio with rewards, upgrades and encounter access.• New-game setup assistant, integration examples and effect diagnostics.• Extensible combat core, ordered battle events, custom effect and status modules.RUNTIME FEATURES• UI Toolkit runtime interface and IMGUI editor tools.• In-game deck editing, card search, copy limits and local saving.• Optional hand fan, card-entry animations and hover previews.• Configurable automatic end turn at zero energy.• Target selection, pile inspection and battle history.• Turn-start checkpoints and victory/defeat screens with battle metrics.• Responsive portrait/landscape layouts and touch-oriented controls.• Restored checkpoint metrics describe the restored segment of the battle.DEPENDENCIESNo external Asset Store dependencies. Uses Unity-provided engine, UI Toolkit/IMGUI and JSON modules. The verified input configuration uses legacy input. Alternative input integrations require validation.VERIFIED CONFIGURATIONSFresh imports verified with Unity 6000.3.1f1 and 6000.4.6f1 using the Built-in Render Pipeline.Windows: native release path tested with Unity 6000.3.1f1. A native shutdown issue was recorded with Unity 6000.4 in the validation environment; use the tested 6.3 editor path for native Windows builds.Desktop WebGL: local browser interaction, loadout persistence and checkpoint restoration verified.Android: an earlier build was approved by the publisher on a Samsung Galaxy A51. Native acceptance of the current 0.3.0 build is pending.Native iOS, macOS and Linux builds have not been verified. URP and HDRP have not been verified and are not advertised as supported in this release.VALIDATOR NOTEAsset Store Tools 12.0.6 completed 37 checks with zero failures and one SRP-material warning. The reported Font Material belongs to BattleTheme.tss importing Unity's default UI Toolkit theme. It uses Unity's internal GUI/Text Shader. The check flags the absence of a RenderPipeline tag. UI text rendered correctly in the validated Built-in configurations. No custom font shader or material is bundled separately.DOCUMENTATIONEnglish developer guides. Signal Break player manuals are provided in English, Portuguese, Spanish, French, German, Italian, Japanese and Simplified Chinese.OpenAI's Codex/ChatGPT tools were used to assist with project planning, C# implementation, editor and runtime interface development, combat and card-behavior systems, integration examples, automated tests, debugging, documentation, player-manual translations and marketing copy. AI assistance also contributed to the code-defined vector diagrams used for sample cards.OpenAI's image-generation tool was used to create the promotional cover, store thumbnail, icon and social-media illustrations. Reference-based generation produced separate compositions, which were resized and exported to the required store dimensions. The fantasy elf illustrations are promotional visuals and are not playable character assets included in the package.Beyond the generated output, the work included integrating the systems into Unity, configuring sample game data and scenes, revising implementations in response to test results and publisher feedback, validating imports in separate projects, and testing gameplay and supported configurations. The publisher approved an earlier Android build on a Samsung Galaxy A51. Current verification limits are listed in Technical details.Gameplay screenshots were captured from the actual Signal Break interface in Unity and native builds. They are not AI-generated gameplay mockups.
