Godot Updates 🚀
Godot Ships Android XR Support for Samsung Galaxy XR
Godot is ready for Android XR and Samsung’s Galaxy XR. The OpenXR vendor plugin v4.2.0 lets Godot 4.5+ projects export directly to Android XR, and the updated Godot XR Editor—now on Google Play—runs on the headset. W4 Games is adding vendor-specific extensions and donating to the Godot Foundation, ensuring long-term support and rapid OpenXR enhancements.
Godot 4.6 dev4: IK overhaul, profiler support, editor boosts
Godot 4.6 dev4 lands with a major animation upgrade: IK returns via new SkeletonModifier3D subclasses like ChainIK, CCD, and FABRIK. Power users also get native buildsystem hooks for Tracy and Perfetto profilers. The Project Manager adds improved keyboard navigation, quick file manager access, and editor settings without opening a project. Plus: OpenXR frame synthesis, Polygon2D oversampling, GridMap line drawing, and more—test early, regressions expected.
Unity Dev Tools 🎮
KWS2 for Unity: Real-Time Bullet Splashes and Wave-Based Water
KWS2 Water System for Unity delivers real-time, wave-based water with dynamic bullet splash impacts, ocean simulations, and realistic rivers. It’s pipeline-agnostic, zone-customizable, and optimized for large-scale environments like calm-to-moderate oceans and small waterfalls. The system simulates interactions with dynamic objects and terrain for believable results.
Build a Unity Live Chat: UI Toolkit + PHP/MySQL
Code Monkey walks through building a live chat system that connects a Unity Editor window to a PHP/MySQL backend and a simple HTML/JS admin page. You’ll wire up UI Toolkit, send/receive JSON with UnityWebRequest, store messages in MySQL, and poll updates from both sides. The tutorial finishes with real-world upgrades—online/offline status and multi-user threads—plus security tips and scalability ideas. A practical, end-to-end guide for adding live support or chat to Unity tools.
Player Interaction & Narrative 💬✍️
Unity x Discord: Integrate the Social SDK in Your Game
Unity and Discord have launched a Unity Learn course that teaches you how to integrate the Discord Social SDK into your game. Add community-driven features to keep players connected both in-game and on Discord. Use the direct links to the course and SDK to get started quickly, with auto-dubbed audio tracks available for accessibility.
Build Branching Dialogues, No Code: Meet StoryFlow Editor
StoryFlow Editor is a node-based narrative tool that lets you design complex branching dialogues without writing code. Export your story as HTML/JSON for use in Unity, Unreal, or Godot, and keep everything fully offline—no subscriptions or cloud. With booleans, conditional logic, and optional images, it’s ideal for reactive, visual novel-style storytelling. It’s available on Steam now, with official engine plug-ins coming soon.
Deep Dives & AI Tutorials 🧠🤖
Mastering 2D Slopes: A Kinematic Raycast Controller Deep Dive
Overhaul your 2D platformer with rock-solid slope and curved-ground traversal. This episode rewrites raycast movement to support climbing, descending, and max-slope sliding, fixes headbump loops, and syncs velocity to surface normals for buttery motion. You’ll also get deterministic flips, velocity snapping, smarter timers, and slope-aware dash/wall-slide. Includes collider best practices and debug visualizations to ship a jitter-free controller.
Real-Time AI Avatars in Unreal: Project R2X, Langflow, and Audio2Face 3D
NVIDIA’s Unreal Fest session shows how to build low-latency, conversational digital humans in UE5 using Project R2X, ACE, and Langflow. See real-time speech-to-speech, tool/function calling, screen-understanding vision, and lore-aware RAG, all driving responsive facial animation via the new Audio2Face 3D diffusion model. The IGGY SDK brings on-device SLMs, ASR/TTS, and VLMs with simultaneous graphics + AI, plus an Unreal sample to jumpstart agentic NPCs without cloud costs.
