Synced randomness?

[KDR_11k]

If I use the synced random number generator it will produce the same results for every game, is there a way to prevent that?

[ILMTitan]

It does? For some reason I thought that a random seed was sent out to all of the clients before the game started, or does Lua use a different synced random number generator?

[TheFatController]

a hackish workaround would be have it generate a load of random numbers in a loop at the start with the size based off everyones start position or ping or something..

Have you tested it or it's just a though? Because there is no reason that the synced random number generator behave like that
.

It's behaving like that, I'm placing a fixed number of planets at random positions in gadget:Initialize() but the resulting positions are the same every time.

guess the seed isn't used or is always the same. looks like a simple one-line omission.

The synced RNG indeed always uses the same seed (18655),
CGame should probably set it to time(0) before broadcasting.

edit: it depends on when and in what context (mod or non-mod)
your gadget is initialized. If the gadget is part of a mod, then its
Initialize() function will be called before CGameServer sends out
the actual seed (CGame only broadcasts 18655 as a temporary
number [*after* gadget initialization is done], even though every
client already knows it), so the RNG naturally generates identical
sequences every time. If however you load it via .devlua at some
frame > 0, then the true final seed sent by the server will already
have been set and the sequences are different.

Can we change the order of those events? I'd hate to have the planets not show up until after all start positions are placed.
