## Protocol packets
Vec is stored as `len:u32 *(data:T)`. All packets are preceeded by a u32
indicating its length.
```rs
type Obj = [u8; 16]
type Res = [u8; 32]
00 connect(identity: u128)
ff disconnect()
01 request_resource(name: Res)
02 respond_resource(data: Vec<u8>)
03 add(id: Obj, prefab: Res)
04 remove(id: Obj)
05 position(id: Obj, pos: Vec3, rot: Vec3)
06 pose(id: Obj, params: Vec<f32>)
07 parent(parent: Obj, child: Obj)
08 sound(id: Obj, data: Vec<u8>)
```
## Resource formats
### Prefab
```
Prefab = *(pos:f32x3 mat:f32_3x3 part:Res<Part>)
```
### Part
```
Part = *(len_key:u16 len_value:u16 *(key:u8) *(value:u8))
Attribute = 0x01 constant:f32 / 0x02 buffer:Res / 0x03 texture:Res<Texture>
NewAttribute = flag:u8 constant:f32 buffer:Res texture:Res<Texture>
```
