Struct SimulationStepContext 

#[non_exhaustive]
pub struct SimulationStepContext<'a> {
    pub dt: f32,
    pub step_index: u64,
    pub scene: &'a Scene,
    pub writeback: &'a mut TransformWriteback,
}

Narrower context for simulation plugins that need a per-step index.

Constructed via RuntimeStepContext::as_simulation inside a simulate-range plugin to get the current simulation step count alongside scene and writeback access.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

dt: f32

Fixed step size in seconds.

step_index: u64

Monotonically increasing step counter (wraps on overflow).

scene: &'a Scene

Read-only scene access.

writeback: &'a mut TransformWriteback

Write transforms to this buffer.
