How do I make engine hum?

[N.Knight]

I'm using arrow key movement in my map. Gameplay includes driving a car.
The question:
How do I make the engine hum? Such that when you press and hold the arrow keys you hear the engine hum and when you release it stops. Please give me a simple GUI trigger example.
~Thanks

You're going to need to download the car sound, then import it into your map.
Once done simply play it.

• Events
  • Player 1 presses arrow key
• Conditions
• Actions
  • Sound - Play carsound.mp3

Do the opposite for release.
