After a bit of searching around, I found that the day-night cycle is controlled by two variables in Player.cpp: https://github.com/TrinityCore/TrinityCore/blob/db8aba662ae94aeaab74ae2ae29c38cf0b8bffb4/src/server/game/Entities/Player/Player.cpp#L22543-L22547
data.Initialize(SMSG_LOGIN_SETTIMESPEED, 4 + 4 + 4);
data.AppendPackedTime(sWorld->GetGameTime());
data << float(0.01666667f); // game speed
data << uint32(0); // added in 3.1.2
GetSession()->SendPacket(&data);
By default, TrinityCore runs at 1:1 TrinityCore:Server time. I want to change that, so the day-night cycle is 10:1. Now, I have experience in Pascal and C#, I’ve never seen << used. A quick google says that it’s for shifting bits, so I assume that it’s not as simple to increase the day-night cycle by just multiplying the float value by 10x. How does that float(0.016666667f) value relate to the passage of day and night? Could I just turn it into 0.166666670f and that’s all that needs to be changed?
Edit: Went ahead and edited the variable just to see if it changes anything. After setting it to float(0.166666670f), it now takes 5 seconds for the clock to advance by one minute. So increasing the float by 10x causes a 12x increase in speed. It’s still a bit slow, so I’ll increase it further.
Edit2: Setting it to float(0.016666667f) now takes the server 3 seconds for 1 minute in game.
