Angle calculator in MMF2

Ok, so I have this following event in MMF1 done with Angle Calculator object, which is unavailable for MMF2. I searched the forum on how to do this in MMF2, but still struggling to use either Atan() or Clickteam Movement Controller to retrieve the angle between two objects correctly.

So what equation should I use to get the exact same value than this event with Angle Calculator:

Anglebp( "Angle Calculator", X( "Active" ), Y( "Active" ), X( "Active 2" ), Y( "Active 2" ))*-1

Thanks!

Use Atan2:
Atan2( Y( "Active 2" )-Y( "Active" ), X( "Active 2" )-X( "Active" ) )*-1

Atan2 only exists in the latest build, so make sure you've updated MMF.
In HWA you have to use some other extension, like the Advanced Direction Object.
