Chunk of misc data

Hi,

Trying to implement something to use in a pipeline where inputs could be math types (mainly float-float4 in this test). Just your thoughts on what I could do here better? Basically I want a struct where [0] might refer to a float2, [1] might be a float3, using a 128 byte buffer. Also no idea when used in a separate op job, how burst will like it. No idea if this would be better using a NativeArray. I’m no expert, but just looking to expand my knowledge from experts :slight_smile:

    public struct Floats
    {
        fixed byte store[128];
        fixed int offset[32];
        int remaining;
        int pos;
        int current;

        public void Init()
        {
            remaining = 128;
            pos = 0;
            current = 0;
        }

        public void Set<T>(T someValue) where T : unmanaged
        {
            var size = sizeof(T);
            if (size < remaining)
            {
                fixed(void* p = &store[current]) *(T*)p = someValue;
                current += size;
                offset[pos + 1] = offset[pos++] + size;
                remaining -= size;
            }
        }

        public T Get<T>(int i) where T : unmanaged
        {
            fixed (void* f = &store[offset[i]]) return *(T*)f;
        }
    }

Why not use NativeStream or UnsafeStream? You can append arbitrary types to it and then read them. Seems similar to what you want.

@CookieStealer2 Yes I do want to convert over to the Native libraries if I get what I want working. That does look like it might be useful if it’s indexes each piece of data of misc length, to work with another index of commands. At this point it is more about the model.
