Error: Array index out of bounds (SOLVED)

[spook1]

I worked with a little trick keeping track of inventory items in my inv box.
now I upgraded to ags27 and the following erro occurs after I pick up my second inv item in the game.

I get the error (which I never got in AGS256):

OK

function repeatedly_execute() {
  // put anything you want to happen every game cycle here

   
  GetLocationName(mouse.x,mouse.y,location_name);
  get_gui = GetGUIAt(mouse.x,mouse.y);
  got_inv  = character[EGO].activeinv;

          if (hadgot_inv != got_inv){ // something changed in active inv
               if (got_inv != -1){
                         character[EGO].inv[got_inv] = 0;
*line51=>*       character[EGO].inv[hadgot_inv] = 1;
                         UpdateInventory();
               }
               hadgot_inv = character[EGO].activeinv;
         }
}

any suggestions??

Looks like hadgot_inv == -1 at that point.
Before line 51, check
if (hadgot_inv != -1)

ok, i'llt ry that.

does it make sense then that this code did work well in AGS256??

It does. Since then AGS started making better checks. Meaning, it was probably something you COULDN't do even then, and therefore it was sheer luck that made it still work. 2.7 doesn't allow that anymore.
