@lezebulon, ECS worked very well for me. I was getting stuck with standard OOP way of doing things and adding new stuff to the game wasn't this easy.
The logic doesn't have to be working on the whole entity. Most of the time (especially for collision, movement and graphics which is what the game is doing most of the time, other stuff is taking less much time) you don't need the whole entity, you are fine with just a component. So, when I draw entities, I just use graphics components which tell me nothing about what entities are these. When I check collision, I don't care what entities collided, I just care that they're collided and I just call their Lua response functions.

But for instance, if thé collision response is to move back the object, how do you tell the graphics component that it has to move?

Àbout needing your data to be contiguous: as I said you probably don't care if instead of iterating over 300 items in an array you do it 3 times for 100 items per array, I doubt thé cache miss world be important
