MMO code : cursor over players[0]

Hi there

I would like to trigger some events when the mouse cursor is over the current playe (Players[0]), but I cannot find how to test see.

I've seen this in the code :

Code:

// move player

      if(Ms.bp(0) && Players.elms()) // on LMB pressed

         if(!Gui.ms() || Gui.ms()==Gui.desktop())

      {

         if(Cur.valid)

         {

            if(Cur.obj.valid())

            {

               if(Chr *chr=CAST(Chr, &Cur.obj()))Players[0].actionAttack(*chr);

            }else

            {

               Players[0].actionMoveTo(Cur.pos);

            }

         }

      }

The object under the cursor is casted to Chr object, if the cast is successful, the pointer character is attacked.
I wanted to use a similar algo to check if my Players[0] is under the cursos, but it failed.
It seems that the Cur.obj.valid() returns 0 when the cursor is over my player.

If I am correct, it means that the cursor update() function ray cast didn't hit successfully... Can somebody explain me why ?
The Players[0] isn't part of the AG_PLAYER actor group ? Or some other reason ?

Thanks guys !

Come on guys, I can't believe anyone came up with something to detect such a click smile

Code:

uint    actor_groups=~(IndexToFlag(AG_PLAYER));

         Vec     pos, dir; ScreenToPosDir(screen, pos, dir);

         PhysHit phys_hit; if(Physics.ray(pos, dir*D.viewRange(), &phys_hit, actor_groups))

cursor ignores player actor

The current player and the "neighbor players" are handled the same way ?
It's seems to me that it's not the casen because with the default settings I can select the neighbors but not my character smile

Where can I define my Players[0] as a AG_PLAYER member ?

EDIT: Oops, I didn't get that, thanks Fex smile

what he is saying is that

uint actor_groups=~(IndexToFlag(AG_PLAYER));

IGNORES the player, so just change

Code:

PhysHit phys_hit; if(Physics.ray(pos, dir*D.viewRange(), &phys_hit, actor_groups))

to

Code:

PhysHit phys_hit; if(Physics.ray(pos, dir*D.viewRange(), &phys_hit))

or you can change the other line from
uint actor_groups=~(IndexToFlag(AG_PLAYER));

to
uint actor_groups=~0
