Sound playbackspeed and vehicle throttle

Hello !

I’m currently having some troubles with the sound playbackspeed when I throttle up and down the vehicle. Here is the script that should change the sound playbackspeed ;

ThrotSound = script.Parent.Engine
ThrotSound2 = script.Parent.Engine2

curSpeed = script.Parent.Parent.State.currentSpeed.Value


    if curSpeed < 10 then
    
    print("aaa")
    
    ThrotSound.PlaybackSpeed = 0.9
    ThrotSound2.PlaybackSpeed = 0.9
    
    elseif curSpeed >= 10 and curSpeed < 20 then
        
        print("aa")

        ThrotSound.PlaybackSpeed = 1.5
    ThrotSound2.PlaybackSpeed = 1.5
    

    elseif curSpeed >= 20 then
        print("bb")
        ThrotSound.PlaybackSpeed = 1.1
        ThrotSound2.PlaybackSpeed = 1.1

    elseif curSpeed >= 30 then
        print("cc")
        ThrotSound.PlaybackSpeed = 1.2
        ThrotSound2.PlaybackSpeed = 1.2

    elseif curSpeed >= 40 then

        ThrotSound.PlaybackSpeed = 1.3
        ThrotSound2.PlaybackSpeed = 1.3

    elseif curSpeed >= 60 then

        ThrotSound.PlaybackSpeed = 1.4
        ThrotSound2.PlaybackSpeed = 1.4

    elseif curSpeed >= 70 then

        ThrotSound.PlaybackSpeed = 1.5
        ThrotSound2.PlaybackSpeed = 1.5
        
    else
        
        ThrotSound.PlaybackSpeed = 1.5
        ThrotSound2.PlaybackSpeed = 1.5

    end

The throttle perfectly works. The speed value changes everytime.

elseif curSpeed >= 10 and curSpeed < 20 then

Try setting an upper bound for the other elseif statements as you did for this one.

#3

Oh, I forgot to modify, but I already tried with the first elseif, and it still doesn’t work.

Are the if statements in loop? If not, the script will only run once and it won’t continuously check for a speed change.

#5

I already tried in the past, but the loop returns an error ;

Add wait(0.1) to the end of the loop. This should fix the error.

It fixes the error, but the script seems to understand only the first if.

while true do

	if curSpeed >= 0 and curSpeed < 10 then
	
	print("aaa")
	
	ThrotSound.PlaybackSpeed = 0.9
	ThrotSound2.PlaybackSpeed = 0.9
	
	elseif curSpeed >= 10 and curSpeed < 20 then
		
	print("aa")

		ThrotSound.PlaybackSpeed = 1
		ThrotSound2.PlaybackSpeed = 1

Did you throttle the vehicle at all during the test? It seems that the speed was only between 0 and 10 for the entire test.

#9

Sure I did, I was going on a speedvalue = 35

So, with proofs ;

Its normal.

Not normal.

Because if you got the speed on the locomotive, it’s 40. I should have this ;


	elseif curSpeed >= 40 and curSpeed < 60 then

		ThrotSound.PlaybackSpeed = 1.3
		ThrotSound2.PlaybackSpeed = 1.3

I think I figured it out. Try defining curSpeed within the while loop. That way, the variable is updating. Otherwise it would remain at the same value the entire time.

#11

Yep ! It works, thanks ! The problem was with that thing not updating, now it does.
