I presume eventually the devs of Dual Universe while add some kind of weather cycle to the game and if so I have some suggestion on how it would affect you and your constructs.
Rain: Rain would slow down your player movement by 25% on regular terrain and 10% on player placed blocks, also reduces visibility by adding water effect on your screen. For ships it would again reduce visibility as
well as reducing accuracy of weapons by 10%.
Snow: Snow would be a more amplified version of rain, reducing speed by 35% on regular terrain and 20% on player placed blocks, again reduces visibility and reduces weapon accuracy by 20%.
Lightning: Though lightning doesn't provide movement penalties like the other two, if your vehicle is struck by lightning it would cause the ships system to shut down for 5-10 seconds, which could result in a crash if you are flying too fast at too low an altitude.
Cold weather: Cold weather would reduce engine efficiency when it is at low speeds as the engine would freeze over, reducing the speed depending on how cold it is, from 10% if it is -5*c to 50% if it is -50*c. At high speeds the engine would produce enough heat as a by-product to keep it working at normal levels.
Hot weather: Unlike cold weather hot weather would reduce engine efficiency at high speeds, as the engine would overheat, reducing the speed from 10% at 35*c to 50% at 70*c, low speeds would not cause enough heat for the engine to overheat.
That's a brief idea of weather and climate and its effects, things could be added, changed or removed and I would like to hear your opinions on the concept.
