    One thing i noted in low level calls in Flutter towards the C# backend... is the use of native types.
  • m
    most "draw" calls, becomes a list of floats
  • m
    so vectors, matrix, etc Arrays of doubles/floats [0.0,0.0]
  • m
    accessors on haxe are overkilling for that?
  • m
    Idk if some "optimized" Array/List/Collection is available to define the memory allocation beforehand as it will work by reference.
  • m
    nvm thought... i'm a rookie on that memory management topic...
  • b
    It's also better to enforce more locality of memory and reduce fragmentation: all primitive typed fields of a same class instance are located in the same area in memory, better for CPU caching etc...
  • b
    Using Point objects completely destroys that in Haxe and creates a lot of fragmentation
  • m
    gotcha
  • b
    But if those Point types are not pointers and actual "structs", then that's fine
  • m
    nop
  • m
    i think there're not "structs"... but anyway, i'm getting ahead of myself.
  • b
    Yea, then you'd better keep the plain fields instead of Point objects performance wise. But it's not like it's going to be crazy slow either if you do use Point objects anyway
  • m
    true
  • m
    but imagine that Flutter relies on "immutability"
  • m
    most objects are "const"
  • m
    and relies on memory pointer hashCode equality.
  • m
    like a point in Flutter is 
    const Offset(dx, dy)
  • m
    you can not mutate it, everything is 'final'
  • m
    same for other geom primitives, like 
    Rect
  • m
    so u keep creating new instances...
  • m
    That tells me Dart has a super optimized GC VM for that sort of mem allocation.
  • m
    idk
  • b
    Yeah I don't know how it works internally
  • m
    it always felt so counter-intuitive.
  • m
    me neither
  • b
    Anyway, the arcade repo is kind of cleaned up from anything directly related to Phaser. Because phaser's v2 arcade physics were using phaser types like sprite or tilemap. Removed all this to have something more agnostic
  • b
    Just "bodies"
  • m
    lovely
