I want to implement Diablo type movement in my game, where you click and the character goes there around obstacles. The only problem is I really have no idea how to implement it, I understand the theroy I just need to see some code, preferably in C++ are there any examples or open source projects on the web you could link me to?

I think A* pathfinding would do what you want. I would take a look at: http://www.policyalmanac.org/games/aStarTutorial.htm for a basic tutorial on the subject.

[edit] here's a link to some A* code w/ an explanation: http://www.generation5.org/content/2000/cpathfinder.asp[/edit]

Links for the lazy of heart.
