==Definition==
'''INT''' fget_angle ( <'''INT''' pointA-X> , <'''INT''' pointA-Y> , <'''INT''' pointB-X> , <'''INT''' pointB-Y> )

Returns the [[angle]] between two certain points. The returned angle will be ranging from 0 to 360000 (0-360º).

== Parameters ==
{|
| '''INT''' pointA-X || - The X-coordinate of point A.
|-
| '''INT''' pointA-Y || - The Y-coordinate of point A.
|-
| '''INT''' pointB-X || - The X-coordinate of point B.
|-
| '''INT''' pointB-Y || - The Y-coordinate of point B.
|}

== Returns ==
'''INT''' : The angle between point A and B.

== Notes ==
The [[angle]] value returned by this function is in thousandths of degrees, as most angles within [[Fenix]] are.
