Struct ScriptedSystem 

pub struct ScriptedSystem { /* private fields */ }

A three-dimensional ODE dp/dt = f(p, t) whose f is a Rhai script.

Implementations

impl ScriptedSystem

pub fn compile(source: &str) -> Result<Self, ScriptedError>

Compile a script from source text.

pub fn load(path: impl AsRef<Path>) -> Result<Self, ScriptedError>

Load and compile a script file, remembering the path for reload_if_changed.

pub fn source(&self) -> &str

The source the system is running.

pub fn path(&self) -> Option<&Path>

The file it was loaded from, if any.

pub fn reload_if_changed(&mut self) -> Result<bool, ScriptedError>

Recompile from the file if it changed on disk since the last load.

Returns Ok(true) when the new script is now running and Ok(false) when nothing changed. If the new version does not compile, or does not return a vector, the error comes back and the previous script keeps running, so a half-typed edit never stops the animation.

pub fn derivative(&self, p: Vec3, t: f32) -> Result<Vec3, ScriptedError>

dp/dt at state p and time t.

pub fn rk4_step(&self, p: Vec3, t: f32, dt: f32) -> Result<Vec3, ScriptedError>

One classic fourth-order Runge-Kutta step of size dt from time t, the same integrator as attractors::rk4_step.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
