If you only want to check if the item is in the backpack you just check with

Code: Select all

if ( item.container == character.backpack )

but if you want to check all the sub containers aswell you have to follow Turleys advice and loop through them

also you can use something like this:

Code: Select all

function IsOnBackPack (chr, item)
	if(!item.container) 
		return 0;
	elseif(item.container == chr.backpack)
		return 1;
	else
		return IsOnBackPack(chr, item.container);
	endif
endfunction

Tericob its better to do a while loop than have a function call itself repeatedly because it will take up more memory and processing going further into call depth. Your script also has the possibility of reaching maximum call depth in the worst case scenario which will halt the script entirely.

Code: Select all

function IsInBackpack(item, backpack)
     while (item.container)
          if (item.container == backpack)
               return 1;
          endif
          item := item.container;
     endwhile
     return 0;
endfunction

This code should work perfect for you.
