Environment design and ECS

[carmine terrace]

Hello, I'm new to dots.
I want to create a scene where tons of npc walks (only left and right from their starting pos) but I want to choose their starting pos in an easy way (from the scene, not full code).
can you suggest me something?

You can place your character in required positions in Subscene just like you do this with ordinary gameobjects. After conversion entites remain in those positions.

If i do with ordinary gameobjects i don't get the benefict of ecs (sparse memory allocation for gameobjects instead of array of componentdata). isn't it?

If you place objects in subscene they will be converted into entites.

mmm...
i'm testing in the unity sample https://github.com/Unity-Technologies/EntityComponentSystemSamples/blob/master/EntitiesSamples/Assets/HelloCube/README.md
and using a GameObject.FindObjectOfType<MeshRenderer>(); it retrieves the component of a gameobject inside the subscene that should be converted to entity

Is your subscene closed?

Or have you left it open

@carmine terrace I'd suggest to go over some tutorials so they can walk you through basics of working in dots

oh, you are right! I had the subscene opened in editor. after closing it. The subscene gameobjects are now entities.
