Dynamic Buffers

[solar bough]

Where are dynamic buffers allocated and how? Is it using UnsafeUtilities.Malloc?

[late grail]

I know that it’s Allocated in the chunk if it’s within the size you declared with the attribute for buffer size

And outside the chunk if the size extends beyond that, but not entirely sure on exact technical implementation

[worldly heath]

Outside of chunk just does a normal malloc(persistent)

[solar bough]

I see, there is no batching then or a memory pool

[solar bough]

@worldly heath do you know where it happens on source code? the call to malloc?

I don`t really like how adding to dynamic buffers need a sync point. Is it true that it needs a sync point?

[worldly heath]

it does not

unless you mean on main thread?

in which case it needs to sync any job using it

[solar bough]

Don`t it execute on main thread always? even if on job it is using CommandBuffers that execute on main thread

[worldly heath]

If you're just adding to a dynamicbuffer in a job there's no command buffer or main thread

[solar bough]

Why would i use a dynamic buffer instead of unsafe list?

If i don`t need to bake it

[worldly heath]

why would you use an unsafe list instead of a dynamic buffer?

you have to manage the memory

if you dispose the entity, how do you clean up the unsafe list memory
