"Coin" sound effect should get a bit faster if you collect multiple in a straight row

Help and Feedback Scripting Support
#1

Hello , I have a script that will generate a line of ‘coins’. each coin has a sound effect in it. So if you’ve ever played subway surfers, yo will know that if you collect multiple coins in a row, the sound effect gets faster each coin. I want to have that same effect, but I have no idea where to start. I tried finding the closeest part, but it would not work. Can i have help please

You could create a localscript which is responsible for playing the sound.

When your character touches a coin, you can keep track of two variables

lastCoinTouchTime - The time the character touched the last coin.
coinTouchCount - How many coins have been touched so far.

You could check if the lastCoinTouchTime is within a threshold (e.g. 5 seconds), you can increment coinTouchCount and set the Sound’s pitch to it. Otherwise set coinTouchCount to 0.

Pseudo-code:

-- Localscript

local lastCoinTouchTime = 0
local coinTouchCount = 0

function coinTouched()
    if (os.clock() - lastCoinTouchTime) < 5 then
        coinTouchCount += 1
        sound.PlaybackSpeed = 0.8 + 0.2 * coinTouchCount
    else
        coinTouchCount = 0
        sound.Pitch = 0
    end

    lastCoinTouchTime = os.clock()
    sound:Play()
end

So like @majdTRM has said, you would save the time of the last time you collected a coin, in a variable. Use this to determine if you’re still on a streak of collecting coins.

This is with simple logic:

local lastcointouch = 0
local coincombo = 0

local pitchloop = {1.1,1.13,1.15,1.13}

local function OnCoinTouch()
	if tick() - lastcointouch < 1 then
		coincombo = coincombo + 1
	end

	-- Formula and logic should be tinkered with so you get a pitch you like!
	local Combo = coincombo
	local pitch = 1 + (Combo / 100)
	
	if pitch > 1.15 then pitch = 1.15 end

	sound.PlaybackSpeed = pitch
	sound:Play()

	lastcointouch = tick()
	-- rest coin script here
end

This is with better sounding, more complex logic.
You should tinker with the numbers to get a sound you like.
Hopefully it works a little:

local lastcointouch = 0
local coincombo = 0

local pitchloop = {1.1,1.13,1.15,1.13}

local function OnCoinTouch()
	if tick() - lastcointouch < 1 then
		coincombo = coincombo + 1
	end

	-- Formula and logic should be tinkered with so you get a pitch you like!
	local Combo = coincombo
	local pitch = 1
	
	if Combo >= 15 then
		Combo = Combo - 15
		Combo = Combo % 4
		pitch = pitchloop[Combo + 1]
	else
	    pitch = 1 + (Combo / 100)
	end

	sound.PlaybackSpeed = pitch
	sound:Play()

	lastcointouch = tick()
	-- rest coin script here
end

You pasted the 3 scripts 3 times, could you fix that and also use the code block feature?

print("Hello world!")
