Getting a bigger size for uint16?

[gotenxds]

Hello, I'm using the latest compiler with C#
To illustrate the issue I made this simple schema:

`
namespace World;

table WorldTile {
spriteIndex:uint16;
}

root_type WorldTile;
`
I save this data in a vector, there are 100000000 (100^4) items in it

So I would assume the file would be around 200mb, as 100000000 * 2 to mb is 200
but I get 400mb

Note that I get the same result if I change the data type to uint32

You are apparently storing the same table in each element of the vector, otherwise the result would would likely be 1.2GB

Tables are stored independently, have a vtable offset (32-bit), and when you create a vector of them, you create offsets to them (32-bit). So your entire file is offsets to the same table.

If you change table to struct in the schema you get the 200mb you expect. More on the difference between these two in the docs.

Hi @aardappel thanks for the quick answer, I'm using the createWorldTile(builder, spriteIndex) insdie the loop so I cant really see how it's the same, maybe the spriteIndex is the same so flatbuffers optimizes it ?

No, it shouldn't optimize those away automatically.
