Fireflies turning on and off

[Granamir]

Ok i'm done.
Here u can find lua file:
https://onedrive.live.com/redir?resid=D ... 900F%21181

or if u prefer here is the script:

Code: Select all

-- set timerInterval to 0.1 or 1

siAccendono = {} -- keep in memory if fireflies have to turno on or off
inizioAttesa = {} -- keep in memory when they last changed

function lucciole()
	-- settings
	local tempoInizio = 1.02 -- starting time of the day fireflies start turning on
	local tempoFine = 1.98 -- end time of fireflies dance
	local luminositaMassima = 8 -- max brightness, default is 4
	-- edn of settings
	
	local oraDelGiorno = GameMode.getTimeOfDay()
		
	-- night
	if oraDelGiorno >= tempoInizio and oraDelGiorno < tempoFine then
		local contatoreSciami = 1											-- these two lines can find
		local sciame = findEntity("forest_fireflies_" .. contatoreSciami)	-- all fireflies in game
		while sciame ~= nil do
			local randomLuce = (math.random()*5)+1	-- random light changing time
			local randomParticelle = (math.random()*5)+5 	-- random particle/fireflies changing time
			if sciame.light ~= nil then
				if siAccendono[contatoreSciami] == true then
					if Time.currentTime() > inizioAttesa[contatoreSciami] + math.max(randomLuce,randomParticelle) then -- higher time (after ">") higher turn off time
						local nuovaLuminosita = math.random()*luminositaMassima -- random brightness
						local coloreRandom = math.random(1,3) -- chose a color between 3
						inizioAttesa[contatoreSciami] = Time.currentTime() -- starting turning on
						sciame.light:setBrightness(nuovaLuminosita)
						-- sciame.light:setColor(vec(math.random(),math.random(),math.random())) -- christmas tree effect
						if coloreRandom == 1 then
							sciame.light:setColor(vec(0.2, 0.75, 0.5, 0))
						elseif coloreRandom == 2 then
							sciame.light:setColor(vec(0.2, 0.7, 0.6, 0))
						elseif coloreRandom == 3 then
							sciame.light:setColor(vec(0.1, 0.5, 0.3, 0))
						-- elseif coloreRandom == 4 then -- if u want add some colors remember to change nunber in "coloreRandom" (just before this "if")
							-- sciame.light:setColor(vec(0.3, 1, 0.75, 0))
						end
						sciame.light:fadeIn(randomLuce)
						sciame.particle:fadeIn(randomParticelle)
						siAccendono[contatoreSciami] = false
					else
					end
				elseif siAccendono[contatoreSciami] == false then
					if Time.currentTime() > inizioAttesa[contatoreSciami] + math.max(randomLuce,randomParticelle) then -- higher time (after ">") higher lighted up time, still brightness differences can look like some fireflies turned off
						inizioAttesa[contatoreSciami] = Time.currentTime() -- starting turninf off
						sciame.light:fadeOut(randomLuce)
						sciame.particle:fadeOut(randomParticelle)
						siAccendono[contatoreSciami] = true
					else
					end
				elseif siAccendono[contatoreSciami] == nil then -- starting cicle at night start (tempoInizio you chosed at beginning of script)
					inizioAttesa[contatoreSciami] = Time.currentTime()
					local caso = math.random(0,1)
					if caso == 0 then
						sciame.light:fadeOut(randomLuce)
						sciame.particle:fadeOut(randomParticelle)
						siAccendono[contatoreSciami] = true
					elseif caso == 1 then
						sciame.light:fadeIn(randomLuce)
						sciame.particle:fadeIn(randomParticelle)
						siAccendono[contatoreSciami] = false
					else
					end
				end
			else
			end
			contatoreSciami = contatoreSciami + 1
			sciame = findEntity("forest_fireflies_" .. contatoreSciami)
		end
	else
	
	-- day
		local contatoreSciami = 1
		local sciame = findEntity("forest_fireflies_" .. contatoreSciami)
		while sciame ~= nil do
			if sciame.light ~= nil then
				local randomLuce = (math.random()*10)+1
				local randomParticelle = (math.random()*10)+10
				sciame.light:fadeOut(randomLuce)
				sciame.particle:fadeOut(randomParticelle)
				siAccendono[contatoreSciami] = nil
			else
			end
			contatoreSciami = contatoreSciami + 1
			sciame = findEntity("forest_fireflies_" .. contatoreSciami)
		end
	end
end	

... u can have interesting effects with negative brightness too

BTW anyone knows what is 4th value in color vec for? default is 0 and changing seems having no effects

[Batty]

I am guessing 4th value in color vec is for alpha AKA transparency.

[minmay]

All vectors are 4 elements, but not all fields will actually use all 4 of those elements. Colours where alpha doesn't make sense (such as light colour), offset, etc. don't use the fourth element I'm pretty sure. All arguments to vec() default to zero, so you can just leave off the 4th parameter to improve readability.

Thank you guys.
