IT界討論區(58) 唔講上一份人工

青花瓷 2019-3-7 16:34:06 係咪講緊
client 收到msg {x=1, velocity=1 ,time=10}
但係client local time係10.1 所以client個x 應該set做 x=1.1

實驗羊 2019-3-7 16:35:15 Client local time I think is irrelevant to a game, can’t imagine any case.

Maybe I’m wrong, you got any examples?

青花瓷 2019-3-7 16:37:38 client禁制signal遲左一秒先send到server,
要補番果一秒比client

實驗羊 2019-3-7 16:43:11 That’s for anti lag system by determining the next second right?

I think it’s a bit 9 because my experience with League of Legend it’s useless.

手一黏便緊(UTC+9 2019-3-7 16:43:22 呢個係game logic上面點處理亂序同delay既package 睇你個game既性質係點
但係首先係開game之前你要對到錶例如A個clock係10000 B個clock係20000咁呢個係clock skew
然後仲有A同B既clock speed唔一定一樣例如A每秒100 B每秒102咁呢個係clock drift (其實同一部device既clock都未必平穩因為溫度變化之類
咁你就要開場之前measure晒之後一路玩每個package都有個sender time 接收個方就可以換算返做receiver time
有左呢個time之後再睇你個game logic去判斷亂序既package既優先性同埋啲motion點interpolate

例如我之前寫個隻係有招捉人既被捉隻角就無得出招
咁被捉個隻野既出招package可能後啲send 但係先啲到
咁就要係game logic層面諗點搞個底層time library只係確保每個參加者都會收到正確統一timestamp既package

手一黏便緊(UTC+9 2019-3-7 16:45:11 如果你用單一server去出clock 咁就local time is irrelevant
不過電話網絡會好多lag感或者要係game logic層面做好複雜既extrapolation

實驗羊 2019-3-7 16:49:39 I guess if you are very eager to solve the lag issue and fairness, but I think it’s an effort with not much output, I guess for a open source project if you make such PR it’s not gonna hurt to include it.

手一黏便緊(UTC+9 2019-3-7 16:53:09 其實又唔係好大effort
group埋一齊咁講出黎咪好似要寫幾日咁
但係其實當時係逐件逐件上一開始只係對錶搞左clock skew
之後見兩分鐘後啲UX有啲奇怪咪加埋clock drift入去
成件事其實分佈落黎個workload好light

青花瓷 2019-3-7 17:52:50 咁其實隔一段時間reset clock skew咪得，唔使理clock drift

可以試下嘅

實驗羊 2019-3-7 18:37:06 Depends on what game la
