How to make retarder sound in A-Chassis bus?

[Jayboetrein]

Hello!

I have a question, how do I script a bus using A-Chassis to let it make a sound when the bus brakes? The pitch depends on the speed of the bus. It’s also called a retarder.

An example of a retarder: https://www.youtube.com/watch?v=PqdOInn88MI
It’s the “weeeeeeeee” sound when braking.

Thanks in advance!

While braking play the sound and use a script that reads the vehicles velocity to change the playbackspeed.

Thanks! Could you provide everything I need to add, and explain it like I’m 5? Sorry but I’m really bad at scripting lol.

Find the section of function code in the A-Chassis script that deals with braking and when that fires you can start to play the retarding sound (nice, I just noticed the filter blocks the word in the preview window so you can tell before posting what’ll be hashtagged!).
When that happens you should run a loop that has the retarding sound in it like I linked. The speed of the bus will control how much the sound changes. Make sure there’s a check in there to make sure you’re still braking (something like while vehicleseat.Throttle == -1 do) and if not then end the loop.

Give it a try first, then copy/paste the code here if it doesn’t work. Make sure to put 3 backticks (```) before and after so it formats properly. We shouldn’t be writing scripts for you, but we can check what you’ve done and suggest corrections.

Thanks! I’ll try it tomorrow, as it’s 10pm here lol.
