jecs is Just a stupidly fast Entity Component System
|
||||
|
||||
- Entity Relationships as first class citizens
|
||||
- Iterate 800,000 entities at 60 frames per second
|
||||
- Type-safe [Luau](https://luau-lang.org/) API
|
||||
- Zero-dependency package
|
||||
- Optimized for column-major operations
|
||||
- Cache friendly archetype/SoA storage
|
||||
- Unit tested for stability
|

|
||||

|
||||
|
||||
local function parent(entity)
|
||||
return world:target(entity, ChildOf)
|
||||
end

||||
local function getName(entity)
