Ok i got the script to show global variable over entity but what about local variables is there any way you can show local variables. Example there is only one action attached to all enemies and you want to display there health over there head? Any Idea?

make temporary global variables, which you keep swapping with local variables..?

Local variables can't be shown in panels for good reasons: They are only valid local and therfore it can neither be guaranteed, that at least any of these local variables exists, nor can be distinguished between multiple instances of the same local variable. So Helghast's suggestion is the way to go.

maybe use text_draw for local vars (skills)?

This may work:
- define a local string (outside the while loop of the enemy)
- get the world coordinates of the position you want the text to be shown at
- translate the coordinates to screen coordinates using vec_to_screen
- inside the while loop, translate the skill to string using str_for_num function
- draw the sting using draw_text and the screen coordinates plus the string

Xarthor it works perfect thank you very much. it was almost impossible to show local variables over entities but you solved it in a very easy way

But the str_for_num doesn't work it gives error can you give me an small example please.

Code:

action enemy_act()
{
  VECTOR my_pos;
  STRING* my_health;

  while(me)
  {
    if(vec_for_screen(my.x,camera))
    {
      vec_set(my_pos,my.x);
      my_pos.z += 50; // z-offset
      vec_to_screen(my_pos,camera);
      str_for_num(my_health,my.skill22); // replace my.skill22 with your health skill
      draw_text(my_health,my_pos.x,my_pos.y,vector(255,255,255));
    }
    wait(1);
  }
}

It gives the following error!

Yes thats because you are using C-Script and my code is Lite-C.
Try this one instead:

Code:

action enemy_act
{
  var my_pos[3];
  string my_health;

  while(me)
  {
    if(vec_for_screen(my.x,camera))
    {
      vec_set(my_pos,my.x);
      my_pos.z += 50; // z-offset
      vec_to_screen(my_pos,camera);
      str_for_num(my_health,my.skill22); // replace my.skill22 with your health skill
      draw_text(my_health,my_pos.x,my_pos.y,vector(255,255,255));
    }
    wait(1);
  }
}

dont save the script as .WDL, save it as a .C file instead!

that'll make it work ^_^

Hi!

We were looking at a similar problem under "E1513....by ngisiger"
The solution (2 of them)

STRING* my_health;

was to remove the * or place this line outside the ACTION.

Hope this helps

I've looked at the manual and found the answer
