Game development tool
Scaleform GFx is a game development middleware package, a vector graphics rendering engine used to display Adobe Flash-based user interfaces and HUDs for video games. As a result of Autodesk's acquisition of Scaleform Corporation in March 2011, Scaleform GFx has become part of the Autodesk Gameware line of middleware.
Authors create user interfaces using Adobe Flash authoring tools, such as Adobe Flash Professional; the resulting SWF files can be used directly by the GFx libraries, providing similar functionality to the Adobe Flash Player but optimized for use within game engines.
All major platforms are supported, including game consoles, mobile and PC operating systems. Scaleform provides APIs for direct communication between Flash content and the game engine, and pre-built integrations for popular engines such as Unity, Unreal Engine, and CryENGINE. Scaleform GFx can also be licensed for use as a standalone Flash runtime system on mobile platforms, competing with Adobe AIR.
Scaleform GFx contains several core systems, including:
- a GPU-accelerated rendering engine for display objects, featuring a vector-to-triangle tessellation engine with an edge anti-aliasing algorithm that uses subpixel triangles to smooth the edges
- mesh rendering backends for DirectX and OpenGL APIs
- a mesh cache to manage tessellated triangle data
- a vector-graphic based font system that uses a single texture to dynamically cache glyphs on demand
- support for all major Flash display classes including Sprite, MovieClip, TextField and Filters (Glow, Bevel, DropShadow, etc.)
- optimized ActionScript 3 and ActionScript 2 virtual machines with garbage collector, as well as GFx-specific ActionScript extensions
- audio support via a licensee-implementable C++ interface, with a default implementation supporting FMOD
In addition to the engine, documentation, and samples, the Scaleform GFx SDK includes several additional components:
- Scaleform 3Di
- ActionScript 2 extensions allowing for three-dimensional location and rotation of Flash elements. Scaleform 4 includes support for ActionScript 3's built-in 3D capabilities, making 3Di unnecessary.
- Scaleform CLIK
- Common Lightweight Interface Kit - easily customizable Flash UI component framework, including buttons, list boxes, drop down menus, sliders, trees and windows, created in collaboration with gskinner.com. These components are intended to be lightweight, while providing for bi-directional communication with the engine and other considerations for game development.
- Scaleform UI Kits
- Prebuilt customizable examples including sample C++ engine and ActionScript code, as well as corresponding Flash content. These currently include an MMO UI, FPS HUD, and frontend menu kit.
- Scaleform AMP
- Analyzer for Memory and Performance - profiler tool used to analyze memory and performance of Flash content inside a game or 3D application while running on PC, console or mobiles. AMP is similar in purpose and design to Adobe Scout. AMP gives detailed stats for CPU usage, rendering, and memory, and includes a complete ActionScript profiler with function and per-line timing.
Scaleform also provides two optional add-ons for GFx:
- Scaleform Video
- Fully integrated video codec for Flash Video workflow support (currently powered by CRI Movie.)
- Scaleform 3Di
- Fully integrated Input Method Editor (IME) for Asian chat support.
