Game crashes when variable is set to item count

[maia]

That sums it up.

Whatever item I try to count.

Like...

set variable = # of potions posessed.

Crash.
This is what it says:

Script 'Game_interperter' line 750: NoMethodError occured.

undefined method '[]' for nil:nilClass

[modern algebra]

Hmm, doesn't for me. GO into the editor and post the script surrounding line 750 please

[maia]

That's the thing... this is default.

I have not edited anything. I was just using the event system.

As for line 750 here it is:

      actor = $game_actors[@parameters[1]]

Here are the lines before and after 750

def command_122
    value = 0
    case @params[3]  # Operand
    when 0  # Constant
      value = @params[4]
    when 1  # Variable
      value = $game_variables[@params[4]]
    when 2  # Random
      value = @params[4] + rand(@params[5] - @params[4] + 1)
    when 3  # Item
      value = $game_party.item_number($data_items[@params[4]])

750      actor = $game_actors[@parameters[1]]


      actor = $game_actors[@params[4]]
      if actor != nil
        case @params[5]
        when 0  # Level
          value = actor.level
        when 1  # Experience
          value = actor.exp
        when 2  # HP
          value = actor.hp
        when 3  # MP
          value = actor.mp
        when 4  # Maximum HP
          value = actor.maxhp
        when 5  # Maximum MP
          value = actor.maxmp
        when 6  # Attack
          value = actor.atk
        when 7  # Defense
          value = actor.def
        when 8  # Spirit
          value = actor.spi
        when 9  # Agility
          value = actor.agi
        end
      end
    when 5  # Enemy

Hmm, that's wrong for several reasons that I can see. Make it look like this instead:

Code Select Expand


def command_122
    value = 0
    case @params[3]  # Operand
    when 0  # Constant
      value = @params[4]
    when 1  # Variable
      value = $game_variables[@params[4]]
    when 2  # Random
      value = @params[4] + rand(@params[5] - @params[4] + 1)
    when 3  # Item
      value = $game_party.item_number($data_items[@params[4]])
    when 4  # Actor
      actor = $game_actors[@params[4]]
      if actor != nil
        case @params[5]
        when 0  # Level
          value = actor.level
        when 1  # Experience
          value = actor.exp
        when 2  # HP
          value = actor.hp
        when 3  # MP
          value = actor.mp
        when 4  # MaxHP
          value = actor.maxhp
        when 5  # MaxMP
          value = actor.maxmp
        when 6  # Attack
          value = actor.atk
        when 7  # Defense
          value = actor.def
        when 8  # Spirit
          value = actor.spi
        when 9  # Agility
          value = actor.agi
        end
      end

Note that the method is further broken.  I no longer remember the actual line-number before I grabbed the fixed method, but

Code Select Expand

when 3  # Mul
        $game_variables[i] = value should be

Code Select Expand

when 3  # Mul
        $game_variables[i] *= value.

Your fully-corrected method should look something like this, if we've caught all the errors:

Code Select Expand

THANKS!!!

This has fixed the SET VARIABLE to ACTOR parameters too!!!
