I keep getting an undefined method error

Code: 
Script 'Game_Weapon' line 22: NoMethodError occurred
undefined method 'x' for nil:NilClass

Which is refering to this line (and probably the other lines using .x and .y)

@sprite_bullet.x += @bullet[i[0]]

I'm using DerVVulfmans Revised Mouse Script.

Anyone have any an anwser to my problem?

Such a simple fix.


        @sprite_bullet.x += @bullet[i[0]]

should be

        @sprite_bullet.x += @bullet[i[1]]


reason:      if @bullet[i[2]] == 1 effects what it is. The reason your Y doesn't have a problem is because you set it to the variable of 1. Set this to 1, and it should be fixed.

Based on the script, I think he is trying to make a bullet fire, and he is having a problem with this area.


The only problem i see is an uneven variable, besides that, it should work.


Any ideas khmp?

      if @bullet[i].need_delete
        @bullets.delete(@bullet)
      end
    end
  end
end
If Got it right, this is a better way of doing what you want, I comment some things, if you don't understand reply back and i will try to explain, if something is not working reply and I will try to fix it ;)

Good luck!

".size" method is giving me errors in your script.

And is anyone able to tell me why my original one isn't working? I have a feeling its somthing so simple but i just can't figure it out.

EDIT: Ok, ive tried everything, i just dont get it.

# ** Mouse Input Module (Revised)
#------------------------------------------------------------------------------
#   by DerVVulfman
#   version 1.2
#   08-18-2007
#------------------------------------------------------------------------------
#   Based on...
#   Mouse Input Module
#   by Near Fantastica
#------------------------------------------------------------------------------
#   Set_Pos feature by
#   Freakboy
#------------------------------------------------------------------------------
#
#   THE CALLS: 
#
#   Mouse.click?
#   This returns a true/false value  when you test whether a button is clicked.
#   The values you pass are 1 (for the left mouse button), 2 (for the right) or
#   3 (for the middle button).
#
#   Mouse.press?
#   This returns a true/false value  when you test  whether a button is pressed
#   and kept depressed.  The values you pass are 1 (for the left mouse button),
#   2 (for the right mouse button), or 3 (for the middle).
#
#   Mouse.pixels
#   This returns the  mouse's screen coordinates  in pixels.  Based on a screen
#   with a 640x480 dimension,  this returns an array of the mouse's position in
#   index values.  Calling Mouse.pixels returns both x & y positions  in a sin-
#   gle string,  but calling Mouse.pixels[0] returns the x position (0-639) and
#   calling Mouse.pixels[1]  returns  the y position (0-439).   If the mouse is
#   outside of the game's window region, this call returns nil.
#
#   Mouse.tiles
#   This returns  the mouse's screen  coordinates  in map tiles.   Based on the
#   system's 20x15 tile size,  this returns it in index values  (a 0-19 width & 
#   a 0-14 height).  This functions the same manner as Mouse.pixels.
#
#   Mouse.set_pos
#   This allows you  to forcefully position the mouse at an x/y position within
#   the game screen by pixel coordinates.  Given the game's normal screen width
#   of 640x480, adding:  Mouse.set_pos(320,240)  should position the mouse dead
#   center of the gaming window.
#
#   Mouse.update
#   Add this routine  into your update routines  to update  the mouse position.
#   It must be called otherwise you won't get valid mouse coordinates.

  end  
end

Thats all the code ive change/used instead of the defulats. Mouse goes above main, create any sized picture named "bullet.PNG". Two things have been added to Scene_Map which i have enclosed in comment blocks. This time i tried directly placeing my code into Scene_Map.

It seems using an array it deletes itself or somthing so when i call ".update" or ".x" or ".y" after the main calculation it isn't assigned as a sprite instance.

My mistake here is the fix
Code: 
#==============================================================================
# ** Game_Weapon
#------------------------------------------------------------------------------
#  This script controls the gun operations.
#==============================================================================
class Bullet
  attr_accessor :x,:y,:x_speed,:y_speed,:need_delete
  def initialize
    #Your Stuff just copied
    @x = 320
    @y = 240 
    @x_speed = 0 
    @y_speed = 0
    @sprite = Sprite.new
    @sprite.bitmap = RPG::Cache.picture("bullet.PNG")
    @need_delete = false
  end
  #-----------------------------------------------------------------------------
  #Moves the Bullet
  def update
    return if @sprite.disposed?
    @x += @x_speed
    @y += @y_speed
    @sprite.x = @x
    @sprite.y = @y
    #checks if outside the screen
    if @sprite.x < 0 || @sprite.x > 640 || @sprite.y < 0 || @sprite.y > 480
      @need_delete = true
      #Removes sprite
      @sprite.dispose if !@sprite.disposed?
    end
  end
end
#==============================================================================
class Game_Weapon
  #-----------------------------------------------------------------------------
  def initialize
    @bullets = []
    @bullet_speed = 20 #Set this to your own value
  end
  #-----------------------------------------------------------------------------
  def trigger
    if Mouse.click?(1)
      if ( @bullets.size < 30) #Check if you haven't used the 30 bullets
        bullet = Bullet.new
        angle = Math.atan2((Mouse.pixels[0]-320)/((Mouse.pixels[1]-240)*-1))
        bullet.x_speed = @bulletspeed / Math.sin(angle) #Set the x speed
        bullet.y_speed = @bulletspeed / Math.cos(angle) #set the y speed
        #Adds the new Bullet
        @bullets.push(bullet)
      end
    end
  end
  #-----------------------------------------------------------------------------
  #UPDATE ALL BULLETS
  def update
    #Runs through all the bullets and Updates them
    for i in 0...@bullets.size
      @bullets[i].update
      #IF outside the screen
      if @bullets[i].need_delete
        @bullets.delete(@bullet)
      end
    end
  end
end

lol, that worked, but it fires when i dont click and when i do click i get an error.

EDIT: Ok, i did more checking and at random intervals i get an integer error. And the bullet moves about 45 degrees in the wrong direction. Maybe it due to my math, not sure though, ill have a look at it.


Also, anyone have an answer to my first script. I knida want to know why it doesn't work so that i can improve on my future scripts.

Math.atan2 takes two parameters I only see one. Try using:
Code: 
angle = Math.atan2(Mouse.pixels[0]-320,Mouse.pixels[1]-240)

And you need to dispose of the bitmap thats held within the sprite.
Code: 
@sprite.bitmap.dispose

You might want to create a disposal method for both the bullet class and the weapon class. Disposing of the weapon should dispose of all the bullets that are currently in use. Stick with the object oriented approach that Eduardo is suggesting. It's a hell of lot cleaner and Scene_Map main doesn't look like a used diaper. You can use alias_method to add code to main and update without overriding both. But these are design decisions I'll take a look into why the mouse thing is bugging.

Code: 
#==============================================================================
# ** Game_Bullet
#------------------------------------------------------------------------------
#  This class will hold the bullet information that will be used inside Game_Weapon
#==============================================================================
class Game_Bullet
  def dispose
    @sprite.bitmap.dispose if !@sprite.bitmap.disposed?
    @sprite.dispose if !@sprite.disposed?
  end
end

#==============================================================================
# ** Game_Weapon
#------------------------------------------------------------------------------
#  This script controls the gun operations.
#==============================================================================
class Game_Weapon
  def dispose
    @bullets.each {|bullet| bullet.dispose}
  end
end

#==============================================================================
# ** Scene_Map
#------------------------------------------------------------------------------
#  This class performs map screen processing.
#==============================================================================
class Scene_Map
  alias_method :opt7_gameweapon_main, :main
  alias_method :opt7_gameweapon_update, :update
  def main
    # Create a new weapon.
    @weapon = Game_Weapon.new
    opt7_gameweapon_main
    # Destroy the weapon.
    @weapon.dispose
  end
  
  def update
    # Update the weapon which will update the bullets.
    @weapon.update
    # Check to see if the user wants to shoot again.
    @weapon.trigger
    opt7_gameweapon_update
  end
end

It is to my understanding that the bitmap of a sprite must also be disposed of. Sadly now I must ask a question. Does disposing of the sprite object also dispose of the bitmap? Or does it slip through until garbage cleanup occurs?
