Crazyninjaguy's Lesson 2 in RGSS

[Crazyninjaguy]

Ok, so we've learnt about printing and declaring variables, and you may have learnt about the different types of variables. Just make sure you've read Lesson 1 first! So now onto the next lesson.
The structure of a class.

Let's jump straight in shall we? But first remember to make your Lesson 2 script section won't you.

class Class_Badger # Line 1
  def method_one # Line 2
  end # Line 3
  
  def method_two # Line 4
  end # Line 5
end # Line 6

Alright lets go with the explanation.

Line 1

The word "class" tells the game that we are writing a new class, and the class name here is Class_Badger. We must have a name for the class, otherwise we wouldn't have anything to call in the game would we? (More on calling later).

Line 2

The word "def" shows that we are writing a method, and the method name in this case is method_one. You must have a name for a method otherwise there is nothing for it to run, and it will probably cause errors.

Line 3

The word "end" tells the game that we have finished writing that method and we can move onto the next one.

Line 4

The next method

Line 5

Ends the second method

Line 6

This "end" is special because it ends the class and tells the game that there is nothing else in this class and to stop the process of running it.

So that's the basic structure of a class. But it is basic. So let's add some padding.

class Class_Badger # Name of the class
  def initialize # The initialize method. If that isnt there, nothing works
    @badger = 'Badgers Rule!' # Stores a value in the variable @badger
    badger2 # Calls the next method
  end # Ends the method
  
  def badger2 # The method we just called
    p @badger # Print the variable we declared earlier
  end # Ends this method
end # Ends Class_Badger

I've added some comment lines to explain it all as this is pretty easy and we've done it before. (The variables and printing.) Always remember to indent (RMXP does it for you) because it will be easier to understand in big scripts.

Ok, so if you put that script section into the Lesson 2, everything should be fine right? Wrong. To see the effects of this script you have just written, you need to create a new event on a map, and set the starting party position to that map. Ok, in the event you have just created, give it a graphic or sprite so you can see where it is. Double click on the character you have just made on the map, and double click the @> in the big white space to the left. Navigate yourself to the third page of the popup and choose Script... at the bottom. In the popup that...well...pops up, type in Class_Badger.new This shows the game that we want to call a script section. So for any other class that you write, to call it, it will be Class_Name.new Then run your game and go up to the character and press the spacebar. Look! The popup said badger!

Congratulations! Your first working class!

But that's not all for this lesson. Just to check if it's all sunk in, i want you to write me a class, below are the things you have to do.

Homework!

Create a class called Class_Yourname (Yourname being your name obviously).

The class needs to have two methods, the first one being the 'def initialize' one.

In the initialize method, declare 2 variables and store them in another.

In the second method, print the 3rd variable (The one with the two variables stored inside).

End the class and hand me in your homework here to this thread.

Until the next lesson!

class Class_PokemonPlatnum
  def initialize 
    @pokemon = 'so '
    @platnum = 'cool :)'
    pokemonplatnum2
  end
  
  def pokemonplatnum2 
    p @pokemon+@platnum
  end 
end

My Homework :L

Uh, First and only problem is its "RUBY" not "RGSS"

 

[Crazyninjaguy]

RGSS stands for Ruby Game Scripting System which is what RMXP uses.
RGSS is an API for Ruby, so learning RGSS is sort of learning the basics of RUBY too.

@PokemonPlatnum, nice work ;)

I understand that but when it really comes down to it your writng scripts in RUBY. However Learning RUBY is more of a smarter way to go because its a programming language and can be used for web programming... Anyways Great tutorial way to help out everyone lately keep up the great work... I like reading your topics.

True true.
When i started scripting, i had no idea it was based on ruby lol, last year around september i decided to learn a bit of ruby to help myself write cleaner scripts, and it paid off :)

Thanks :D
Good to know that people appreciate it :D

I'm going to look like a complete idiot for this, and I bet the solution will be obvious xD

Here I go:

Apparently I have a syntax error on line 23 - I checked it, replace p with print, reverted it...nothing worked, here's the code (Oh gawd, I'll open a shop Homework Extensions 'R' Me =P)

#############################################################################
#This is my simple demo script involving CLASSES and VARIABLES              #
#############################################################################

class Basic_Script
  def initialize
    @me = 'I am'
    variable2
  end
  
  def variable2
    @metwo = 'starting to understand.'
    merging_variables
    
    def merging_variables
      @full_script = @me + @metwo
      final_result
    end
   
    def final_result
      p @full_script
    end
    end

Okay, that set aside, I've tried several guides, not understanding much other than print (I knew a little bit of BASIC, not much, but enough to aid knowledge of languages such as this ^-^ Also, I am aware that that's programming and this is scripting BUUUUT...).
However I come and read this and understand it right down to the full stop.
Excluding my seemingly random error I think I've done fine.

Thanks for this, it really does help!

EDIT:

This is line 23 (No need to count xD)

 p @full_script

 

[Crazyninjaguy]

Yup, the solution is really obvious :D

You forgot to end the variable_2 method :P
Once you've ended it it should be fine :)

Remember, if there's a syntax error on the last line, you haven't ended something properly.

 

[Time Shift Dialga]

Oh...right, thanks!

I thought it might have been something to do with how I put the other two variables into that one...*places dunce's hat on head* :P

 

[Missingno.7-4468]

I am a sucker for tuts.

class Bibarels_Are_Awesome
  def initialize
    @Bibarels = 'Bibarels are awesome'
    talkin
  end
  def talkin
    @K = ' Okay?'
    bout
  end
  def bout
    @Awesomeness = @Bibarels + @K
    bibarel
  end
  def bibarel
    p @Awesomeness
  end 
end

Anyway, I really wanna learn this, and presently, it doesn't seem as hard as it did when I first hear about this(Oh so long ago)

My Homework

Nvm, here's my homework.

class Class_Testing # Name of the class
def initialize # The initialize method. If that isnt there, nothing works
@Testing = 'Testing...123...Hope this works.' # Stores a value in the variable @badger
testing2 # Calls the next method
end # Ends the method

def testing2 # The method we just called
p @Testing # Print the variable we declared earlier
end # Ends this method
end # Ends Class_Badger

I fixed my prob. from before if anyone read the message.
