OVERVIEW:

Echodream's architecture has a lot of similarities to ECS architecture, but it is not true ECS for two reasons:

​

• ​Entities are behaviors (not just ID numbers)

• Components are behaviors (not PODs)

​

What it does share with the ECS design pattern:

 

• Entities are updated by systems which act on all the entities with the requisite component type(s)

• Entities are accessed through their ID numbers instead of pointers (entities do not have stable memory addresses, so only temporary pointers/references can be used)
