Gameplay language bindings
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.
