This hierarchical tag system allows you to manage conditional systems, react selectively to events, and learn about Unity's TreeView and ReorderableList systems with ease.

A hierarchical tag design is an easy and efficient way to simplify many otherwise-complicated systems. This system allows you to create a collection of tags, add or remove them from containers in the editor or during gameplay, and compare the contents to determine what should happen during gameplay.

Tag container comparisons not only check whether the tags themselves are present, but also whether any child tags are present. In addition, every tag is an object so references are preserved even if they are re-arranged or re-parented in the editor.
