[Crash] Often game crash for at least 1 player each time

[rarigate]

My map frequently crashes upon loading for at least 1 player (most of the time it's just 1 player who crashes). The error is {294} ERR: path component index out of bounds. Any idea what causes this problem?

I had a similar problem when using a custom ui. If the player had alt-tabbed during the loading of the game they would desync.

Is the person actually crashing or are they being booted back to the score screen?

Make sure to check your calls of BlzGetClientScreenWidth/Height. When alt-tabbed they return zero which will cause a thread crash if you divide them, resulting in a desync for the tabbed player.

Score screen, but sometimes just the blizzard error with the yellow triangle and a cd-key looking error

If you get kicked to the score screen it's likely a desync. You can check your Documents\Warcraft III\Errors folder to see if a desync log was generated. It should generate one for other players as well. In the log it should state what turn the player desynced on, if it's on turn 001 then you either have some async code that runs on map initialization that causes the desync, or the person desyncing played a map before yours and something in their cache is leftover causing a mismatch on your map. I know CreepCampPathingCellDistance and some other gameplay constants can desync when playing different maps.

Crashes are another issue entirely.

If your map is in Lua you also need to make sure all objects are created from within the main function.

Most of the time it works, but it's just unfortunate to remake when 1 player gets desynced. Any desyncs related to Set Unit Skin function?

Also, isn't this a culprit?

Neither of those are an issue. I gave you multiple reasons why it might desync in my last post.

Hello @TriggerHappy do you think that ReloadGameCacheFromDisk causes desync in Map Initialization? It's the anti SP method I use and have been skeptical abt it

 

[TriggerHappy]

Maybe. Try removing it.

 

[rarigate]

Will do so, what anti singleplayer method should I use as substitute since isSinglePlayer is a bad one

Hey can you explain exactly what you mean by this, cause my map crashes and uses Lua.

Also if your map crashes/kicks 1 player during loading, try running your map initialization trigger at game time 1.00 instead. I know if you do things like checking if player slots are filled/empty while loading it can descyn.

Bad:

someTimer = CreateTimer()
function main()
end

Good:

someTimer = nil
function main()
    someTimer = CreateTimer()
end

 

[rarigate]

What anti SP method is recommended now?

 

[BradPittlord]

I see thanks, is it fine to call a function that creates the objects, within the main function?
Like this

function main ()
     setglobals ()
end

function setglobals ()
     sometimer = createtimer ()
end

Yes.
