How to set the bus destination text?

I noticed the text changes during a Bus Route stage, but is there a way to edit the text on the destination signs so it doesn't always say not in service?

 

I second this question, because I would like to change the destination sign outside of the Bus Route stages.

 

You have to do the bus thing, and werever it goes it shows.

 

We know that, but what Joey is asking is how to change it OUTSIDE of the Bus Route stages.

 

is there more icons

 

It WORKS!
It's very cool to use.
I'm going to try the letter "א" in it.
the letter shown is the letter Alef by Hebrew alphabet, In English, It's the letter A.

 

Yeah, I tried and nothing happened.

Aeight, so when you ingame (but your vehicle MUST the bus) then click `~ button

and so you must see colourful text. Then in the bottom you can see Lua. thingy then click it, then it should be giving you some things, just click the vehicleLua or similar like that. After that write in the textbox (or command executor box )like this: controller.onGameplayEven("bus_onRouteChange", {direction="direction", routeID="42"}) . You can change the direction and numbers by renaming the 'direction' and '42' words enclosed in the " symbols like: controller.onGameplayEvent("bus_onRouteChange", {direction="in service", routeID="771"}) . For the logo, replace the '42' number to [bng] [air] or [bus] . The [ ] symbols NEED to be included or it gonna gave you the letter, not the logo. If you still not get it to use the logo, here's the example:
controller.onGameplayEvent("bus_onRouteChange", {direction="in service", routeID="[bus]"})
Hope this helpful

 

Where is the app?

 

It was never released. You have to go to the console and input the command to set the destination.
