Hi; I want to know if there is a formula to determine if the user is moving the mouse clockwise or counter clockwise. If there is could you explain to me? Thanks Hadi

Calculate the angle for a vector from the center point to the mouse pointer, and watch how the angle changes.

Hi, Get the x position of the mouse location. If the X attribute of the first position is less than the second, the mouse will bi moving clockwise, vica versa. Good luck jamil abou khalil

Take three different sample points A, B, C visited by your mouse. Compute the vectors AB = v1 (v1x, v1y) , AC = v2 (v2x, v2y). Sign of v2x* v1y - v1x * v2y will tell you the result: positive = clockwise. 0 = aligned visited points negative ... Regards
