FrameScript

FrameScript is a high-level scripting language designed for controlling frame-based animation and interactive behavior within multimedia, game, and UI frameworks. It emphasizes deterministic frame progression, enabling developers to author per-frame logic that coordinates timelines, transitions, and scene updates.

FrameScript combines a compact syntax with a dynamic, reference-based runtime and tight integration with host engines. It supports first-class functions, closures, and a pragmatic event model, enabling both imperative instruction sequences and reactive bindings. The language provides timing primitives and libraries for animation curves, easing, and interpolation, as well as a property binding system that synchronizes scene graph nodes with script state. A module system and package manager allow reuse of components across projects. Garbage-collected memory management and optional type hints offer a balance between flexibility and performance, while sandboxing and restricted execution modes help isolate scripts in complex applications.

FrameScript code typically runs inside an embedding engine or runtime, which exposes APIs for accessing scenes, timelines, input, and rendering. Implementations vary; some runtimes compile common paths to bytecode, others interpret scripts with JIT optimizations. Tooling commonly includes a debugger, hot-reload support, and a timeline editor that couples script events to frames.

Common use cases include cutscenes, UI transitions, procedural animation, and responsive interfaces where behavior must be synchronized to frame updates. Adoption is strongest in engines and authoring tools focusing on timeline-driven content, though the language competes with general-purpose scripting languages in some ecosystems.
