Yes I am making a first person game but it isn't a shooter. It is a game with swords and magic. Thank you all for your help. I was reading AUM 107 and came across a code that might do the trick although I have not tried it yet.
Here it is:

Code:
VECTOR palm1, palm2, sword_direction;

 

STRING* sword_mdl = "sword.mdl";

 

function attach_sword()

{

       proc_mode = PROC_LATE;

       set (my, PASSABLE); // the sword shouldn't slow down the player

       while (you)

       {

               // get the vertex at the bottom of the palm in Med

               vec_for_vertex (palm1, you, 28);

               // get the vertex that separates the thumb and the pointer finger in Med 

               vec_for_vertex (palm2, you, 9); 

               // compute the vector that will be used by the sword

               vec_diff (sword_direction, palm2, palm1); 

               // rotate the sword accordingly

               vec_to_angle (my.pan, sword_direction); 

               // put the origin of the sword in the vertex that is placed at the bottom of the palm

               vec_set (my.x, palm1); 

               wait (1);

       }

}

 

action spearman_action()

{

       var anim_percentage = 0;

       ent_create (sword_mdl, my.x, attach_sword); // attach the sword to the player

         while (1)

       {

               anim_percentage += 3 * time_step; // 3 = "walk" animation speed

               ent_animate(my, "walk", anim_percentage, ANM_CYCLE); // play the "walk" animation

               c_move (my, vector(5 * time_step, 0, 0), nullvector, IGNORE_PASSABLE | GLIDE);

               my.pan += 2 * time_step; // 2 sets the radius of the circle

               wait (1);

       }

}




That way whatever weapon will move how I want it when animate the player model's arm.

boolean my.awesomeness = so true;
