• int32 inputFrameId = 1

• repeated uint64 inputList = 2

  Indexed by "joinIndex", we try to compress the "single player input" into 1 word (64-bit for 64-bit Golang runtime) because atomic compare-and-swap only works on 1 word. Although CAS on custom struct is possible in Golang 1.19 https://pkg.go.dev/sync/atomic@go1.19.1#Value.CompareAndSwap, using a single word is still faster whenever possible.

• uint64 confirmedList = 3

  Indexed by "joinIndex", same compression concern as above

  this is the instantaneous scalar attribute of a character, different from but will be accounted in "velX" and "velY"
