Calculate angle between two points
Posted on 2009-06-29
Math math mat! :D
I got two XY points, what Im trying todo is set the first XY1 to "move towards" XY2, in my application. I assign new XY positions for XY1 every 100ms or so. So to the math:
What I remember from school is that I need to use some sort of variation of the phytagoras theorem?
The new X and Y are C1 and C2 of the right angled triangle, and the hypotenuse is the direction in wich XY2 is relation to XY1.
So I know the length of the hypotenuse and calculate the angle between XY1 and XY2, can I calculate the C1 and C2 from that?
Hope I made sense, math is hellova fun, it's just to hard to manage for some of us.. :P
