What is making Lush Season windy?

Recommended Posts

The porkland prefab adds the worldwind component, but when you check the worldwind component's OnUpdate function, it checks whether or not there is hurricane wind before actually spawning winds - and hamlet does not have hurricane winds. So how does Hamlet's lush season spawn winds?

function WorldWind:OnUpdate(dt)
	if not self.inst then 

	self.timeToWindChange = self.timeToWindChange - dt

	if self.timeToWindChange <= 0 then
		self.angle = math.random(0,360)
		self.inst:PushEvent("windchange", {angle=self.angle, velocity=self.velocity})

		self.timeToWindChange = math.random(MIN_TIME_TO_WIND_CHANGE, MAX_TIME_TO_WIND_CHANGE)

	local sm = GetSeasonManager()
	local windspeed = sm:GetHurricaneWindSpeed()
	if windspeed > 0.01 and (sm:IsHurricaneStorm() or (sm.IsWindy and sm:IsWindy()) ) then
		self.windfx_spawn_rate = self.windfx_spawn_rate + self.windfx_spawn_pre_sec * dt
		--print(string.format("wind %f, %4.2f, %4.f", sm:GetHurricaneWindSpeed(), self.windfx_spawn_rate, self:GetWindAngle()))
		if self.windfx_spawn_rate > 1.0 then
			local px, py, pz = GetPlayer().Transform:GetWorldPosition()
			local dx, dz = 16 * UnitRand(), 16 * UnitRand()
			local x, y, z = px + dx, py, pz + dz
			local angle = self:GetWindAngle()

			self:SpawnWindSwirl(x, y, z, windspeed, angle)
			self.windfx_spawn_rate = self.windfx_spawn_rate - 1.0
