Get the current rotation of a player. The default is to get the rotation for
the first player spawned in the Minecraft world, but this can be run for a different
player by using the player_id argument.
Usage
getPlayerRotation(player_id = NULL)
Arguments
player_id
Integer giving the ID of a player. You can find IDs of all
current players using getPlayerIds.
Value
A double vector of length 1 with a value between
0 and -360 giving the angle of rotation of the player. (The value is always negative.)
Values near 0/-360 indicate a player facing North (moving forward would increase position in the
"x" direction.)
