sceneFixedPass method

void sceneFixedPass(
  1. double fixedDt
)

Walks this node's subtree once per physics substep and dispatches Component.fixedTick to every component.

Called by Scene's fixed-step driver inside its substepping loop, before the physics world's step. Traversal order is parent before children, matching scenePrePass.

Implementation

void sceneFixedPass(double fixedDt) {
  _visitMutable(_components, (component) => component.fixedTick(fixedDt));
  _visitMutable(children, (child) => child.sceneFixedPass(fixedDt));
}
