Basically I want to use Floyds routine to make one item look at another item but with tweening.

Here is the new code. How can I make it work with atan2 to make something point at something else? I tried but get negative spinning again.


Angle = Atan2( y2 - y1 , x2-x1 ) + 90
If Angle<360 Angle:+360
if Angle>360 Angle:-360

'NOTE: I assume something is wrong with how I generate Angle... it somehow breaks floyd's code below despite being in the range.

' Assumes p1 and p2 are in the range [0,360) and t is in [0,1].
Function TweenAngle#( p1# , p2# , t# )
	
	Local angle# = p1 + t * (p2 - p1)
	
	If p1 <= p2 Then Return angle
	
	angle :+ t * 360.0
	
	If angle < 360.0
		Return angle
	Else
		Return angle - 360.0
	End If
	
End Function
