Ich komm hier nicht klar 
Wie funktioniert das , das ich jede Fahrstuffe bis zu einer bestimmten Geschwindigkeit abspielen kann?
habe hier mal en beispiel :
local soundeffectsutil = require "soundeffectsutil"
function data()
return {
tracks = {
{ name = "vehicle/v100/DRV100_Leerlauf.wav", refDist = 25.0 },
{ name = "vehicle/v100/DRV100_Stufe01_fahrt.wav", refDist = 25.0 },
{ name = "vehicle/v100/DRV100_Stufe02_fahrt.wav", refDist = 25.0 },
{ name = "vehicle/v100/DRV100_Stufe03_fahrt.wav", refDist = 25.0 },
{ name = "vehicle/v100/DRV100_Stufe04_fahrt.wav", refDist = 25.0 },
{ name = "vehicle/v100/DRV100_Stufe05_fahrt.wav", refDist = 25.0 },
{ name = "vehicle/train_diesel/_wheels_ringing.wav", refDist = 25.0 },
{ name = "vehicle/train_diesel/_brakes.wav", refDist = 25.0 }
},
events = {
clacks = {
names = {
"vehicle/clack/modern/part_1.wav",
"vehicle/clack/modern/part_2.wav",
"vehicle/clack/modern/part_3.wav",
"vehicle/clack/modern/part_4.wav",
"vehicle/clack/modern/part_5.wav",
"vehicle/clack/modern/part_6.wav",
"vehicle/clack/modern/part_7.wav",
"vehicle/clack/modern/part_8.wav",
"vehicle/clack/modern/part_9.wav",
"vehicle/clack/modern/part_10.wav"
},
refDist = 25.0
},
horn = { names = { "vehicle/v100/horn_v100.wav" }, refDist = 25.0 }
},
updateFn = function (input)
local axleRefWeight = 20.0
local value = gain
local value = pitch
return {
tracks = {
