Unsolved Variable with other text

Code:

    ],
    "soundscape": [
        ["name", "src"],
        ["siren", "radio/1.ogg"],

Does anyone know how to replace the "1" with a variable so I can select between multiple tracks?

 

It depends on your mod. If your siren are selectable, just write several parts.
Like this:

Code:

"X1":{
...
...
...
"soundscape": [
        ["name", "src"],
        ["siren", "radio/1.ogg"],
...
...
},
"X2":{
...
...
...
"soundscape": [
        ["name", "src"],
        ["siren", "radio/2.ogg"],
...
...
},
"X3":{
...
...
...
"soundscape": [
        ["name", "src"],
        ["siren", "radio/3.ogg"],
...
...
},
"X4":{
...
...
...
"soundscape": [
        ["name", "src"],
        ["siren", "radio/4.ogg"],
...
...
},

But if your sirens aren't selectable, I recommended you to write your these codes in your:
In the jbeam:

Code:

"soundscape": [
["name", "src"],
["siren", "radio/1.ogg"],
["siren", "radio/2.ogg"],
["siren", "radio/3.ogg"],
["siren", "radio/4.ogg"],

And in your lua:

Code:

local siren1 = nil
local siren2 = nil
local siren3 = nil
local siren4 = nil
local function onInit()
    siren1 = siren1 or sounds.createSoundscapeSound("siren1")
    siren2 = siren2 or sounds.createSoundscapeSound("siren2")
    siren3 = siren3 or sounds.createSoundscapeSound("siren3")
    siren4 = siren4 or sounds.createSoundscapeSound("siren4")

If you do it, you'll have several tracks and you can use them

 

I don't have a lua file, I would make one but I don't know the code. I'm just using the soundscape with the default lightbar function. Can I not use variables then?

 

Try something like this in .jbeam file. It will make several parts in a slot.

Code:

"X1":{

...
...
...
"soundscape": [
       ["name", "src"],
       ["siren", "radio/1.ogg"],
...
...
},
"X2":{
...
...
...
"soundscape": [
       ["name", "src"],
       ["siren", "radio/2.ogg"],
...
...
},
"X3":{
...
...
...
"soundscape": [
       ["name", "src"],
       ["siren", "radio/3.ogg"],
...
...
},
"X4":{
...
...
...
"soundscape": [
       ["name", "src"],
       ["siren", "radio/4.ogg"],
...
...
},
