Game Dev help

Ok so I've programmed a non-tile based isometric game but now I'm stuck on making it move correctly isometrically.

Currently my character moves from one point directly to the other. However I now want to move him isometricly (2 points across for every one point down) so I will need to move him twice to get to the one point. Once going across and down and once going across and up, as shown in the diagram below. Does anyone have any idea how to calculate where point A is on the diagram? I've been racking my brains and can't think of a single trigonometric formula. So say if one point is (10,10) and the other (200, 100) how do I calculate where point A would be and where he changes direction.

What language is this game in? Could you post the current pathfinder code?

Objective-C. Currently there is just point to point code. Basically I need the pseudocode of how to calculate the location of point A.

Ok, so at the moment I'm working out the equation of each line and now I need to work out their point of intersection. Usually you can just say one equation equals the other and work out x from there but you can't in programming so does anyone have another way to work out the point of intersection. Maybe by subbing in values?

Well done :D

I suggest using C++, more compilers etc and cores to help you in near future like Torque.

Do you have any idea what you are talking about?
