> checkChildrenDidChange(container, previousData): boolean

Defined in: node_modules/pixi.js/lib/scene/container/utils/checkChildrenDidChange.d.ts:18

Internal

This function will crawl through the container essentially check if the children have changed.

This function checkChildrenDidChange recursively checks if any child in a Container or its children has changed. It does this by comparing a generated changeId for each child against a stored value in previousData. The changeId is a combination of the child's uid and _didChangeId, bitwise manipulated for uniqueness. If a change is detected, it updates previousData and sets didChange to true. The function returns a boolean indicating if any change was detected in the entire hierarchy of children.
