Questions about game messages

[Tal'Rarity]

Can they desync? If so does GetLocalPlayer fix them on top of creating empty existing strings then using those for local player?

Also does this desync and if so why?

It shouldn't desync since it is already using a local.

By the way is there by any chance a list of desync's for some of the functions Blizzard unsafely handed us?

Game messages won't desync as far as I know. There is a rumor about string table desyncs, which goes as followed:

When a string is used in wc3, it will be entered into a string table. When the string is accessed again, wc3 will look in the string table instead (saves performance). The rumor is that if a string is entered locally, it'll mess up the table and cause a desync.

However, this issue kinda sprouted up without any justification. I tested it a while back, and it doesn't seem to desync. I didn't test it incredibly thoroughly, though. But I believe it is just a rumor that spread around. Even if the table ends up out of sync, it doesn't seem to be enough to cause a disconnection (at least not by itself).

Clearing a screen of text messages for a force won't desync. The general rule of thumb is that visual effects tend to be safe. Creating/destroying things usually are unsafe. But there are actually more specific rules (as noted in my tutorial in my sig).

By the way is there by any chance a list of desync's for some of the functions Blizzard unsafely handed us?

There might've been another one. I forgot. But that is the main one to look out for.
