[Crash] Things that causes desnch without GetLocalPlayer()

[Lord_Earthfire]

Hey guys,

i have found out that a project of mine, while running properly on singleplayer, causes a desynch right at the lnitialisation of the map.

So i gave the triggers with the corresponding event a look, but neither of these uses getlocalplayer, which is the most common cause of desynchs. So i wanted to ask for a good list of things which can cause a desynch

First things that come to mind:
- Certain camera pan actions (the smart one iirc).
- Getting unit height after any sort of terrain deformation (shockwave, warstomp, etc).
- Triggered terrain modifications seem to have some issues, though I don't know specifics (had a buddy who had extensive terrain generation during map init and could never fix the desyncs it caused).

Hmm, its neither of these (i was aware of the deformation crash, so i have refrained from using that one.) i believe i try to get the kloader up and running and look by disabling if truggers if i can catch the issue

Using the jassdb we can easily query all async functions:

$ sqlite3 jass.db 'select fnname from annotations where anname == "async"'

GetDestructableName
GetSoundDuration
GetSoundFileDuration
GetCameraBoundMinX
GetCameraBoundMinY
GetCameraBoundMaxX
GetCameraBoundMaxY
GetCameraField
GetCameraTargetPositionX
GetCameraTargetPositionY
GetCameraTargetPositionZ
GetCameraTargetPositionLoc
GetCameraEyePositionX
GetCameraEyePositionY
GetCameraEyePositionZ
GetCameraEyePositionLoc
GetObjectName
GetLocalizedString
GetLocalizedHotkey
GetLocalPlayer
GetLocationZ
GetItemName
GetUnitName

Async here means that these functions might return different values for different players which in itself doesn't mean that they desync. But if you use the values of these functions in the wrong way it could cause a desync.
Also these are probably all natives since noone annotated the BJ-functions yet.

Ok, thank you very much. I believe this will help alot when i'm searching for the problem
