That... is nothing like how you would go about doing it. That creates an instance variable in Game_Interpreter that is unrelated to how the script retrieves the maximum stack size. You are on the right track in a distant sort of way though. You want to change MA_DEFAULT_STACK_AMOUNT. Well, it's a constant and it's newly defined every time, so even if you had succeeded in changing the value of the constant (which you didn't and shouldn't do), then that change wouldn't be saved in the save file and would revert back to the default the next time the player starts the game.
So, not really the way to do it. A much simpler way is to insert the following code somewhere below the Limited Inventory:
#==============================================================================
# ** RPG::BaseItem
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
# Summary of Changes:
# redefined method - ma_stack_amount
#==============================================================================
class RPG::BaseItem
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# * Stack Amount
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
def ma_stack_amount
return $1.to_i if self.note[/\\STACKMAX\[(\d+)\]/i] != nil
if $game_variables && $game_variables[RPG::MA_DEFAULT_STACK_AMOUNT] > 0
return $game_variables[RPG::MA_DEFAULT_STACK_AMOUNT]
else
return 1
end
end
end
I haven't tested it, but what that does is repurposes the MA_DEFAULT_MAX_STACK constant. Instead of holding the default stack maximum, it now holds the ID of a variable, and the value of that variable will determine the max stack size (though it can never be less than 1).
So now, if you set MA_DEFAULT_MAX_STACK to 20, for instance, then default stack size for items is going to be whatever the value of variable 20 is. So, that will allow you to change it by changing the value of variable 20 through a simple Control Variable command. Note that if the stack max is set individually through an item's notebox, then that will still take priority.
Anyway, tell me if you have any problems with that.
