Audio modding! v3.12

The new features for prop modding keep coming!

You can now import your own audio files (mp3) into the game and attach them to prop mods!

This means you can:

Make props which give off ambient sounds (e.g. engines, factories, nature, animals, sirens, loudspeakers, etc)
Make props which play sound effects on click (e.g. station voice call-outs, horns, sound boards, etc)
Create your own in-game music players which you can turn off & on!

So far people have already made things like an i-pod dock which plays music, or a Nokia phone with a ringtone, ambient sound sources (like a station platform, nature ambience, industrial ambience) and even some memes (of course ːsteamhappyː)

The possibilities of using custom audio in your mods are endless!

Like for example, this classic old radio made by Ze Trackmeister:

Making this update made me realize just how much audio variety was missing from Rolling Line. I Personally haven't paid much attention to ambient audio (beyond the classic "top of the south" main layout) and it has never been much of a priority.
But now I've remembered just how much ambient audio can bring a layout to life!

Thanks to these new audio modding features, everyone has the ability to completely control the ambience of their layouts, and I can't wait to see what people can create with this.

For a simple example of what you can do with these new features, here is an example mod I've made for a loudspeaker.
It plays the Rolling Line main theme "Rolling Waves" and you can turn it on/off by clicking on it.

[h2]Audio options [/h2]

This update adds a whole bunch of new settings for your prop mods which you can find in the "Audio Options" menu when editing a mod:

From this menu you can change a whole range of settings to set how your sound behaves:

Audio clip - the mp3 file which will be played (simply put it inside the "custom assets" folder just like other model and texture files)
Loop - set whether the audio clip loops or stops playing when it's done.
Volume - the volume of the clip (1-10).
3D audio - choose between 3D or 2D audio. 2D audio will sound the same regardless of where you are in the room (like background music) meanwhile 3D will fade at a distance and comes from a specific point in the world.
Range - if you choose 3D mode, you can also set the range at which you can hear the sound.
Play automatically - this will set whether the audio will start playing immediately or if you need to click on the prop for the audio to start playing.

Lastly, the option "Play Control Type" lets you choose how the sound is triggered:

None - the audio cannot be controlled (it just plays automatically until it is done/loops)
Click to toggle - clicking on the prop will stop/start the audio clip (like play/pause on an mp3 player)
Click to play - clicking on the prop will play the sound once. Just like a sound board

When the prop is not editable (after clicking "apply edits" or loading a map) then you can simply click on the prop in large or miniature scale to play/stop the audio.

If the prop is editable then you instead need to hover over it and press Q:

[h2]Other features/fixes [/h2]

This update also includes a bunch of other stuff:

Fixed issues with prop snapping (specifically when trying to place letters on the side of buildings).
Lowered the minimum size of snappable props. this means you can use even smaller letters without the snapping going away.
The main layout menu is now FLAT instead of curved. The diagonal sides was a big annoyance for designing menus, so its now flat just like the menu in the custom table room.
Mods will now scale to fit your hand if they are overly large/small. This fixes the issue of large props filling up your screen when held.
There is now a help message when the text input popup is visible.
Adding a new prop mod will now automatically open the mod edit window (instead of bringing you back to the mod list).
Compatible file-types are now shown when choosing assets from the asset folder (e.g. OBJ, FBX, PNG, MP3)
When choosing assets from the asset folder you now have the "empty/none" option which resets the value to empty.
Fixed various UI issues with the modding menus.

There is also now a new example prop mod in the "Rolling Line -> modding -> templates -> prop mods" folder of the speaker (to show how audio features are used).

On a side note, after prop mod snapping was added in the last update we have already got a set of snappable road props on the workshop!

Here's a massive shout-out to Jotrain Gamer for making this amazing set of mods!
He has also made a bunch of excellent traffic lights too.

You can find the full collection of road props here:

Modding is clearly going to be a MASSIVE part of Rolling Line's future, and I've still got lots of features to add! Stuff like mod packs (groups) and animations.

The next update will continue to expand the modding features, but in the meantime have a look on the Steam Workshop at all the amazing stuff the community is already making!

Enjoy!
