The approach replaces pointers with indices, uses intrusive linked lists embedded within structs, and maintains a single flat array to avoid memory fragmentation. Key techniques include circular doubly-linked lists for tree traversal, parent/child/sibling index management, and eliminating dynamic allocations within game entities. The method reduces invalid states, improves cache locality, and simplifies serialization while maintaining safety without shared pointers. ## Full article daily.dev links to this article rather than hosting it.
