Component Definition in UEFN

1. A  self-contained tile for rendering a piece of terrain. Sometimes components are called cells. Also see World Partition.
2. Components are what provide data and behavior to the entities in Scene Graph. Components define what an entity is supposed to be doing in the scene.

Components have editable properties that can be physical, like a static mesh and particle system, or logical, like a gameplay tag or custom Verse code that defines the movement of a platform. By default, all entities have a transform component to specify where the entity exists in the world.

In Verse, a function or group of related functions in a program that can be reused.
