This function takes two sets of XY coordinates. It returns the direction from point A to point B.

Syntax

float findRotation(float Xa, float Ya, float Xb, float Yb)

Required Arguments

• Xa: The X coordinate of the starting point.
• Ya: The Y coordinate of the starting point.
• Xb: The X coordinate of the target point.
• Yb: The Y coordinate of the target point.
