@Darkreaper: Did you put weapons or armor in there? I only made it so that it included items only but I can add weapons and armor if you want. Also, do you have any other custom scripts?

No i didnt try it with armour or anything, just with items and this is the only custom script i have so far

[The Law G14]

Ah, I found out what the problem is, just change that line that has an error, which should be line 94, to this:

CODE

@cooking_window.draw_item(@cooking_window.index)

CODE

@cooking_window.draw_item(@cooking_window.index)

ok no error now but still not showing the item names, just the icon. Tried cooking a few items, but i think they just ended up using them, it did store the value of the item to the variable though. Although its a long string and im not sure what it means

[The Law G14]

That's weird, it should be displaying the item name, what does your event look like?

[Darkreaper]

That's weird, it should be displaying the item name, what does your event look like?

which one, the cooking event? or the display variable event?

[The Law G14]

The cooking event. Also, I've got around making it so that it doesn't show a long string of text when you talk to the display variable event. I've added another $game_variable at line 82 of the script. Just display that variable if you'd like to show the name of the item:

drew this error soon as i tried to cook something

[Show/Hide] Error

????? 'Interpreter 4' ? 161 ??? Argument Error ?????
comparison of String with 99999999 failed

[The Law G14]

Did you put in the game variable for the string of text for the item or the actual item because it's important that you keep them seperate. The first game variable (the one that you had already set) is for cooking, the new one is for showing the item's name. Just send me a PM with the project that has your cooking event and I'll see what I can do

[Darkreaper]

oh whoops :S so wait, what? which ones which? im confused now

On line 90 of the script is where you put what game_variable is assigned the item name. On line 91 is where you put what game_variable is assigned the actual item, which is what you use to cook.

Weird, just send me a demo of your project via PM and I'll edit everything from there

[Darkreaper]

how do you upload an attachment into a pm?

[The Law G14]

Sadly, you can't have any attachments in PMs so your going to have to use sort sort of uploading site like Megaupload or Mediafire.

[tagg1080]

I am sure you guys would appreciate the necro-post, xD


This is a noob question, but I have been having a little trouble trying to figure it out:

RPGM VX, how do I use game variables in a script?
( I understand you guys are in the XP section, but I noticed this was untouched, and thought I might give you guys a small question to answer)


Right now I have a script that adds to stats on level up. (reijubv's)



It works with a hash:


Actor_MaxInc[1] = [ 5 , 3 ,3 , 3 , 1 , 2 , 0 , 0 , 0] #Maximum increment
Actor_MinInc[1] = [ 1 , 1 ,1 , 1 , 0 , 1 , 0 , 0 , 0] #Minimum increment

So the question is, how do I replace the numbers up there^ with game variables?


@game_variable[X] is the right syntax?

But if I place that into the hash, I get a syntax error, so do I need to create separate variables in script, and set then to the variables I want to use, and then make the array with those?

Or is there a more simple way?

This post has been edited by tagg1080: Jan 8 2010, 09:20 AM

[The Law G14]

Well, you got the syntax for variables a little wrong, it should look like this:

CODE

$game_variables[X]

Try putting that into your array to see if it works

[tagg1080]

Well, you got the syntax for variables a little wrong, it should look like this:

CODE

$game_variables[X]

Try putting that into your array to see if it works

Line 86:

Actor_MaxInc[1] = [ $game_variables[9] , 3 ,3 , 3 , 1 , 2 , 0 , 0 , 0]


(Working) Line 86:

Actor_MaxInc[1] = [ 5 , 3 ,3 , 3 , 1 , 2 , 0 , 0 , 0]

Thank you for correction, but I still get^

[The Law G14]

Then put above that line, this:

CODE

x = $game_variables[9]

then replace line 86 with this:

CODE

Actor_MaxInc[1] = [ x, 3 ,3 , 3 , 1 , 2 , 0 , 0 , 0]

[tagg1080]

Then put above that line, this:

# > Changelog:
# V.1.0 (25-04-09) = Initial release
# V.1.1 (29-04-09) = Added a function to restore HP/MP to max when level up
# V.1.1a (30-04-09) = Fixed a small bug wich I forgot to write something in
# the script that can makes the game crashes.....
#-------------------------------------------------------------------------------
# > Information:
# This script will modify an actor's stats gain on level up by a random number
# between maximum and minimum amount that you can specify for each actors.
# For example, you set an actor's minimum AGI stat to 1 and maximum AGI stat to 5,
# when that actor gains a level, he/she'll gains AGI by random number between 1 to 5!
# I suggest you set actor's stats in database to the same from his/her starting level
# to 99, so if in database your actor's HP at starting level is 100, from that level
# to 99 the HP should not be changed! This's just a suggestion anyway....

That is the script^


I am still getting a null error, even with that attempt^

I can't find any solution, so even a messy one would be fine, xD

[Night_Runner]

The problem is that $game_variables isn't yet defined ....
Somewhere in Scene_Title it defines $game_variables = Game_Variables.new, but it reaches this bit of code before it reaches Scene_Title ....

Sorry, ummmmmmmmm, try something like this, it's mostly the same, but kinda not....

[Show/Hide] some code....

  #-------------------------------------------------------------------------------
  # >  by reijubv [aruyasoft@comic.com]
  # >  RPG RPG Revolution
  # >  Released on: 27/04/2009
  # >  Version: 1.1 (April 25th 2009)
  #-------------------------------------------------------------------------------
  # > Changelog:
  #   V.1.0 (25-04-09) = Initial release
  #   V.1.1 (29-04-09) = Added a function to restore HP/MP to max when level up
  #   V.1.1a (30-04-09) = Fixed a small bug wich I forgot to write something in
  #                                    the script that can makes the game crashes.....
  #-------------------------------------------------------------------------------
  # >  Information:
  # This script will modify an actor's stats gain on level up by a random number
  # between maximum and minimum amount that you can specify for each actors.
  # For example, you set an actor's minimum AGI stat to 1 and maximum AGI stat to 5,
  # when that actor gains a level, he/she'll gains AGI by random number between 1 to 5!
  # I suggest you set actor's stats in database to the same from his/her starting level
  # to 99, so if in database your actor's HP at starting level is 100, from that level
  # to 99 the HP should not be changed! This's just a suggestion anyway....

It doesn't error out, but then again, I have no idea what the script actually does or how it works (sorry)

If it doesn't work, it will need a more manual approach, so I'll need to know specifically which stats follow a variable, and it will be applied to every actor...
