getTokenFacing() Function
• Introduced in version 1.3b51
Gets the facing angle for the specified or current token. Values will range from -179 to +180. Default facing is -90 degrees or down, 0 degrees is to the right, +90 degrees is up, +180 degrees is to the left. The jump in the value range is the difference between "exactly left" (+180) and "almost exactly left, but tilted 1 degree down" (-179).
Note that math.atan2_r can be used to calculate facing from a direction given in two coordinate pairs.

Usage
getTokenFacing()
getTokenFacing(id)
getTokenFacing(id, mapname)Parameters
id- The id of the token to get the facing from, defaults to the current token.Note: This parameter can only be used in a Trusted Macro.
mapname- The name of the map to find the token. Defaults to the current map.
Returns
The angle in degrees or "" if no facing has been set
Example
[h: switchToken("Mage")]
[r: token.name]: [r: r = getTokenFacing()]<br>
[h: switchToken("Elf")]
[r: token.name]: [r: r = getTokenFacing()]<br>
[h: switchToken("Hero")]
[r: token.name]: [r: r = getTokenFacing()]<br>
[h: switchToken("Troll")]
[r: token.name]: [r: r = getTokenFacing()]Returns:
