pub fn transform_propagation_system(world: &mut World)
Expand description
A system that propagates local Transform
changes through the scene hierarchy
to compute the final GlobalTransform
for each entity.
This system performs a Breadth-First Search (BFS) traversal of the scene hierarchy. It guarantees that parent transforms are computed before their children, ensuring correctness in a single pass.
It is designed to run once per frame, before the rendering and physics systems.
