How to get the number of the vertex closest to the object or recast or mouse position (Note I need the number of the vertex, not the position)

Dude. Don't start a dozen threads on the same topic. That does not increase your chances of getting an answer; it just annoys the people who might know.

 

ok. but.. How the hell to do that?!

 

You would have to iterate over all the vertices, convert them from world to screen coordinates, compare to the mouse, and keep track of which is closest.
