passing objects to functions

[Captain Mostly]

ok, here's the quadary:

I've made it so that I have a seriese of int's corresponding to objects on screen.

I'm using these int's to define (amongst other things) what graphic that object should appear as e.g:

if (int1 == 5)
object5 image = view 6, loop 1, frame 0


What I'd like to be able to do would be to write a function along the lines of

function intgraphic(X,Z)              //where X is an int (e.g. int1) and Z is an object (e.g. object5)
{
   if(X = 1)
  {
      Z.set_frame = view 6, loop 1, frame 0
  }

   else if(X = 2)
  {
      Z.set_frame = view 6, loop 1, frame 2
  }
etc etc

}


is this possible i.e. is it possible to pass an object into a function? And if you CAN pass an object to a function, what do you write in the header file instead of

import function intgraphic(int,I_DON'T_KNOW_WHAT_GOES_HERE)

To operate an object you use it's ID, right? Therefore it is that number you have to pass into the function. It's usual int btw.

in header:

import function intgraphic(int, int);

so you're saying that the function would look something like this:

function change-graphic-according-to-integer-value(X,Y)
{
if(X == 1)
        {
         object(Y).frame(view loop and frame)
         }


?

Or is there something I missed?


(thanks for all this helping by the way... I don't know what I'd do without it...    Probably not make many games I suppose)

OK, I've got that bit so it doesn't have any errors, but now I've got to the testing point and BAH!!!

When I use the "use inventory on hotspot" interaction option, I don't lose the inventory item (I've not got the "don't automatically lose inventory item" checkbox ticked so it's not that!)
Do I have to type out "lose inventory- blah de blah" for all interactions these days?

ALSO, are arrays numbered in the same way as they are in C++
i.e.
does an array of length 3 go from 0-2 or 1-3?


More questions on the way, when I can work out why it's not working...

aha, that is it.

When I use the "use inventory on hotspot" interaction option, I don't lose the inventory item (I've not got the "don't automatically lose inventory item" checkbox ticked so it's not that!)

There is another possible cause. When you add an item to the inventory AGS doing something like:
character[id].inv[ x ]++;
so it just increases the value
when you lose inventory item it process:
character[id].inv[ x ]--;
instead of character[].inv[ x ] = 0;
Although the way AGS do it is logical there is maybe the source of a problem.

so maybe the player has more than one item actually therefore he loses only one.

Place the line Display("items: %d", character[id].inv[ x ]); to figure out how many exemplars of a certain item the player has really.

ALSO, are arrays numbered in the same way as they are in C++
i.e.
does an array of length 3 go from 0-2 or 1-3?

yes, like in C, the indexation is zero-based therefore the statement:

int vector[3];

declares an array vector with the size of 3 elements. The first element has index number 0 and the last has index number 2.
