mouse control

can someone give me a simple example of code that if the player clicks with the mouse on a mesh the character moves from his postion to the position clicked on by the mouse.

i know it has something to do with camera project but ive not made a game with mouse control before?

i know how to select characters and objects with camera picks but i don't know how to pick a spot on a mesh ?

please keep any examples simple because i rubbish at 3d.

Maybe somthing like this?

;on the mesh being picked 
EntityPickMode mesh,2


If Mousehit(1) ; if the left mousebutton is hit
 pick= CameraPick(camera,MouseX(),MouseY())
            If pick <> 0
            x# = PickedX()
            y# = PickedY()
            z# = PickedZ()
            Positionentity Character,x#,y#,z#
            EndIf
EndIf 

camerapick returns the exact values of where it was picked, so that would be your "spot" on the mesh.
You can get the coords from camerapick by storing
pickedx(), pickedy(), and pickedz() in float points.
Then you just move to that location.

thanks mate i was doing it alittle bit wrong but now ive sean your code ive got it working. ive got very rusty havent done anything in blitz3d for ages so forgoten alot. thanks again
