How to map a range from [-1, 1] to 360 degrees?


Recommended Posts

Hey there,

 So I've snagged onto a little problem while developing my game. 

I'm using Phaser with it's inbuilt support of gamepad. 

The axis of the controller input works in a way such that it returns 1 when held to the right and -1 when held to the left. Here's a picture to make things easier to understand.

How would I map the values to degrees? Here's a visual representation of what I'd like to get.

What's a formula that would allow me to do this?
