# Gameplay language bindings [Back to Use gameplay actions](https://rustic-game-engine.pages.dev/markdown/guides/gameplay-actions.md). Every supported script type exposes `Tween`, `Ease`, `Movement`, `Animation`, `Sequence` / `Timeline`, `Timer`, `Smooth` / `Interpolation`, `Path`, `Camera`, `Physics`, `Effects`, `Audio`, and `Events`. `Clock` controls the shared scene clock. Callbacks stay in their language runtime; action state and math stay in Rust. | Language | Access and construction | | --- | --- | | Lua 5.4 / Luau | Globals; `Sequence.new()`; dot or colon handle calls | | JavaScript / HTML inline JS | Globals; `Sequence.new()`; member calls | | Python | Import modules from `rustic`; `Sequence.new()` | | C++ | Namespaces; `Sequence::create()`; returned shared handle uses `->` (chained methods return a reference) | | C# | `using static Rustic`; `Sequence.New()`; typed option/clip records | | Java | Extend `Rustic`; `Sequence.create()`; `.waitFor(seconds)`; typed records | | PHP | Static classes; `Sequence::create()`; returned handle uses `->` | | C | Function tables such as `Tween.move`; typed structs; callbacks are function pointers | C uses `Sequence.create()` and explicit `Sequence.destroy(&builder)` / `Path.destroy(&path)` for builder storage. Playback owns its action data after scheduling. C query list strings last until the next lifecycle callback; copy any string you retain. An omitted C callback or easing is `NULL`; easing then defaults to Linear. Native bindings provide typed motion options (`MotionOptions`, `RusticMotionOptions`) for duration or speed. C uses `Tween.toOptions` / `Movement.moveToOptions` for those options. For external languages, install the toolchain in its language guide and regenerate the Programming Workspace after upgrading. Python imports the modules it uses, for example: `from rustic import rustic, run, Tween, Animation, Physics, Audio, Clock`. PHP and HTML entries remain restricted to `ui/`; CSS alone executes no actions. Interpolation aliases Smooth in every SDK. Clock.state() returns scale and paused in every gameplay language. C uses RusticClockState and sets time scale with Clock.timeScale(value); C++ returns RusticValue, C# returns JsonElement, and Java returns a map.
