Open source

Editor tool for importing data from Google Sheets into Unity. Fetches rows via the Sheets API v4, maps columns to C# fields via reflection, and writes them as JSON files or ScriptableObject assets.

Responsive item sizing for Unity uGUI — fit scroll/grid items to any screen (items-per-view, aspect ratio, fixed columns, safe area).

ScrollRect-based snap pager for Unity uGUI — horizontal and vertical axes, dot indicators, number indicators, and prev/next navigation.

Utilities for working with Unity Addressables.

Base project structure for every new KidzDev Unity game (Unity 6000.0, URP 2D, Addressables-first)

Loading panels (fullscreen / progress / spinner / scrim) and a ref-counted input blocker for Unity, plus a Spotlight highlight-cutout system for tutorials/onboarding. Imperative Show()/Hide() handles, no awaited result, sits above whatever screen or popup is showing. UniTask-only, no DOTween, no Addressables dependency.

Production-grade BGM/SFX/Ambience audio service. UniTask async, AudioMixer-backed with dB conversion, cancellable crossfades, pooled sources, plug-in clip loader (Resources default, optional Addressables adapter), and plug-in volume store.

Handy C# / Unity extension methods — strings, collections, arrays, dictionaries, and more.

Runtime skin mix-and-match composer for Spine 2D skeletons (SkeletonAnimation/SkeletonGraphic): category-based part swapping, save-friendly loadouts, single-slot attachment swap, and optional atlas repacking with leak-free disposal. Requires a separately-installed, separately-licensed spine-unity runtime (Esoteric's license forbids redistribution) - this package ships zero Spine assets and is inert until spine-unity is present.

Session/connection/request-pipeline plumbing over the Nakama Unity SDK — client config/environments, auth (custom-id/device-id/pluggable), session persistence + refresh, retrying request runner with typed errors, RPC dispatch, storage CRUD, and socket connect/reconnect lifecycle.

In-game voice chat wrapper over Unity Vivox (com.unity.services.vivox). Facade + seam over group/echo channels, cross-platform microphone permission handling (Android runtime permission, iOS native prompt, desktop device check), and typed VoiceChatResult instead of thrown exceptions.

Render an isolated GameObject through its own camera into an owned RenderTexture — live RawImage feed, one-shot freeze, and export to Texture2D/PNG bytes/Sprite. Plus a whole-screen ScreenCapture grab and an existing-camera capture helper. Multi-instance-safe via spatial isolation (no shared static camera/texture), pipeline-agnostic via Unity's public render-pipeline API (Built-in/URP/HDRP — see README for what's runtime-verified). Zero dependencies beyond UniTask.

Hierarchical notification-badge tree for F2P-style UI: SetCount("shop/daily", 1) lights up shop and the root too, and clears back down once no descendant is still dirty. Unified count model (a dot is just count 0/1), eager O(1)-read aggregation, push-based Observe, uGUI binder. Zero external dependencies.

Non-blocking, auto-dismissing notification banners (snackbars) for Unity uGUI. Fire-and-forget Show(), capped stack with newest-evicts-oldest admission, slide+fade transition, no DOTween, no Addressables dependency.

Cross-platform local notification scheduler over com.unity.mobile.notifications. One facade + INotificationScheduler seam replaces per-platform #if branching; NotificationId derives both Android int and iOS string identities from a single key so the two can never be hand-mapped out of sync. Typed PermissionDenied result (no more permission-wait hangs), facade-level idempotency (cancel-before-reschedule for one-shots, keep-existing for repeating), and cached async launch-notification inspection for deep-link routing.

In-game chat UI on the recyclable-scroll engine — multi-channel feed, text/sticker bubbles, inline emote shortcodes, reply-jump-to-source, new-message pill, backward pagination, and a compose box with a mute/rate-limit gate.

High-performance recyclable ScrollRect for Unity uGUI — object pooling, linear & loop modes, variable item sizes, sync/async item loading.

Minimal analytics event-logging facade. Validates event/parameter names against Firebase Analytics limits before dispatch, buffers events logged before initialization, and warns (instead of silently dropping) on violations. Core has zero dependencies; the Firebase adapter ships as an optional sample.

2D/3D grid system: pure-C# per-cell data storage, A* pathfinding, multi-cell footprint placement, and nearest-available-cell search, plus a thin Unity layer for world/cell conversion and mouse/touch picking. Not a Tilemap replacement — an optional adapter aligns it to an existing UnityEngine.Grid when one is used for rendering. Zero external dependencies.

Generic singleton bases: thread-safe plain C# Singleton<T>, auto-creating MonoSingleton<T>, and non-creating SceneSingleton<T>. Handles the MonoBehaviour lifecycle pitfalls (quit-teardown resurrection, domain-reload staleness, duplicate detection, DDOL placement) so consumers don't have to. Zero external dependencies.

Generic on-disk persistence for any [Serializable] type. JSON + optional Base64, atomic + durable writes, automatic backup-on-corrupt recovery, injectable storage/serializer seams. Zero external dependencies.

Lightweight localization system with UniTask async loading. Supports JSON and ScriptableObject data sources, plug-in custom loaders, and auto-refreshing TMP_Text components.

Modal dialogs for Unity you await for a typed result — ShowAsync<TResult>(), stacked popups, async transitions, and a per-popup loader split (Resources / Direct / Addressables). UniTask-only, Addressables stays optional, zero singleton coupling.

Production-grade multilingual profanity filter. Obfuscation-aware engine (leetspeak, separators, repeat-collapse), allowlist for false-positive prevention, plug-in data loader (Resources default, optional Addressables adapter). Supports English and Thai out of the box.

Two complementary notch / safe-area components for Unity uGUI. SafeArea shrinks a RectTransform to fit inside the device safe area; SafeAreaOutsideMask fills the region outside it with colour bars. Both share one change-tracking core, honour an in-editor device simulator (iPhone X/Xs Max, Pixel 3 XL), guard against Samsung first-frame NaN, and support per-axis ConformX/ConformY control.

Stack-based UI/scene navigation for Unity — push/pop history with a back button, async transitions, and an injectable animation seam. UniTask-only, zero singleton coupling.

Fixes Unity's Image.Type.Filled + Type.Sliced clipping bug with a mesh-correct SlicedFilledImage, so 9-sliced borders stay fixed-size at any fill amount. Zero dependencies beyond uGUI.

Production-grade state machine for Unity — synchronous and UniTask-async flavors, optional transition graph with per-edge guards, QueueLatest policy for button-mash safety, and no-state-collapse guarantees.

Animated text for uGUI/TMPro: marquee ticker, credits roll, auto-fit overflow scrolling, typewriter character reveal, and a count-up number roller. Independent component families, no shared dependency beyond TMPro.

A UI tweening toolkit for uGUI: fade/scale/move/punch/shake/color extension methods, a designer-facing step-sequence player, and button press feedback. No third-party animation dependency by default; an optional DOTween-backed driver auto-compiles when DOTween is already installed in the consumer's project.
