Object is between two angles of another object

In sprite conditions there is "is between angles", but i am not sure how to relate it to other object

For example

Sprite1 is between 0 and 90 degrees of Sprite2 :: (action goes here)

Thanks, i hope you understand what i am saying

You need an expression to get the angle between Sprite1 and Sprite2 with a little math using arctangent (atan(x)).

The angle between the two is atan((Sprite1.Y-Sprite2.Y)/(Sprite1.X-Sprite2.X)).

Edit: Never mind!! I didn't even realize there was a specific angle expression for that. Angle(x1, y1, x2, y2) - Calculate angle between two points
