Rain and Windy weather
Implement the windy effect is quite easy!
On the other hand, adding the rain weather effect took longer than I expected lmao
Trying to balance the “heavy rain effect” alongside with the game performance made me researching about it for quite sometimes.
Hey, finally got it! rather use spritesheets animation than a calculated geometry animation, and topping it with lens water effect, now its good to go!
As mentioned in the Player Survival page, in Nightmare mode, this weather will affect your character, reducing health, slowing movement, and many other negative effects, until you equip the correct apparel, or having some unique items!
