Now server-side code should always use CRandomGenerator::getDefault which is serialized in GH.
CGameState::getRandomGenerator should be only used from GS code and CPackForClient-based applyGs.
TurnInfo contain information about what movement-related bonuses and MP hero going to have on certain turn.
This way we can collect this information once for each turn so it's huge performance boost.
Now pathfinder take into account different bonuses for different tuns. So if you only have FLYING_MOVEMENT bonus from Fly spell for one turn then pathfinder will only let you use air layer within one turn only.
That work for cost calculations too. Let's say you have two bonuses:
- FLYING_MOVEMENT with 20% penalty for next 2 turns
- FLYING_MOVEMENT with 40% penalty for 5 turns
Now pathfinder using correct penalty for each turn so movements in air layer going to be more expensive on 3-5 turns.
