* The angle property is the rotation of the Game Object in *degrees* from its original orientation.

|
|
* Values from 0 to 180 represent clockwise rotation; values from 0 to -180 represent counterclockwise rotation.
|
|
*
|
|
* Values outside this range are added to or subtracted from 360 to obtain a value within the range.
|
|
* For example, the statement player.angle = 450 is the same as player.angle = 90.
|
|
*
|
|
* If you wish to work in radians instead of degrees you can use the property `rotation` instead.
|
|
* Working in radians is slightly faster as it doesn't have to perform any calculations.
