facing

hi i learned trigonometry but i dont know e.g. how many ° is when player is facing X+ and how many ° is when facing Z+

var_dump($player->getYaw());
Shows the degrees the player is facing.
Warning: it may be out of range of 0-360 degrees, but just use ($yaw % 360) to normalize it.
Warning: sin(), cos() and tan() accept parameters in radians. Use deg2rad (or / 180 * M_PI before PHP 7 if you want to make it run faster) to convert degrees to radians.

i know but it take long time so do you know which yaw player has when facing x+ and z+
and thx

Thanks PEMapModder i've add it on onPlayerMove function and it work perfectly !
