(desyncs)

[caleman]

please take a quick look at this thread
http://www.wc3c.net/showthread.php?t=109953&highlight=desync

are they implying that for example simple triggers like:

• Actions
  • Player - Add 1000 to Player 1 (red) gold actual
  • Player - Set Player 11 (dark green) gold actual to 750

makes the map desync? if yes can someone please name more examples

im also interesed in learning more about this "local" thing people keep talking about, thx

No. They are saying those actions (actions that affect the gameplay) only potentially make the game desync if they are within local blocks. Local blocks in the meaning of parts of code that do not get run for every player but only a part of them. You can produce this state by using functions that inherently return async (player-different) values and evaluate a condition with it. The selection will then fire different branches for the different players, thereby you can apply player-specific directives.

The most simple async function would be GetLocalPlayer(), which just returns the player the code runs for. Common uses of local blocks are altering graphics and acustics for a single player. Since this is not of relevance to other players in the game, it does not pose a problem while matching network traffic. Adding gold on a single client could however change the outcome of the game of this player in comparison to the others and this inconsistency may therefore be detected by the engine.

didnt understand everything you said but

i been suffering desyncs, most of the time at the start of the map, i just removed the 2 triggers that added gold to 2 players in map init, do you think the desync problem should be fixed now? ill try my map again when im free in a while

 

[WaterKnight]

There are more reasons for desyncs or at least it's not always as obvious. Even without triggers I remember one problem. If it's at the start of the map and appears most of the time, it should be relatively easy to spot by consecutively deactivating content of your map and testing. But no, we cannot guess it.

Remember you can always test desyncs using http://www.hiveworkshop.com/forums/...multiple-warcraft-3-running-single-pc-226287/

is there a way to know if the game desync when testing with kloader? i tested with 2 warcraft 3 it was supposed to desync but nothing strange happened

usually when my map desync the bot says the message and kicks the players but with lan theres no bot

 

[WaterKnight]

It's possible to desync with kLoader. That's not the same as if you play with any other player across BNet though because the response time will be very fast and you depend on the same operation system. Some desyncs are also related to os specs/configuration.

 

[caleman]

yes but how to detect if my map desync when im doing it with kloader?

 

[Chaosy]

I suspect you mean GetLocalPlayer(). Thats the most common reason for desyncs. I got a tutorial about it.

[WaterKnight]

Just by the fact that your other player gets thrown out of the game. May be not as comfortable as the bot displays it but normally you trigger a message on leave event.

 

[caleman]

there is no kick/leave when there is no bot, just different games

 

[WaterKnight]

We can test it in BNet/Garena if you want. Maybe the bot does some additional checks. "Desync" does not necessarily mean that the game collapses. The game might also split into different states, every group of players continues to play their own version.

 

[caleman]

cant do testing at the moment, but ill keep trying until theres no more desyncs, check this thread tomorrow maybe i post something new
