Ruby-warrior : Teaching AI concepts with Ruby

I think this project doesn't get enough attention :slight_smile:

I've tried it and it's really cool and entertaining. The code is also
pretty cool to look at, and it's got tests and everything.
What is your opinion of it? How far can you go before you have to
actually think? :slight_smile:

That looks really really cool. I'll have to play with that this weekend. Thanks!

Hahaha, I've been studying alot lately and once I finish my tests I'm
definately trying it out, *I've* been with some idea to create a game where
you program stuff in order to do something but in a way that goes
mainstream(and maybe be a good way to learn how to program).

Hello guys! I consider RubyWarrior may be useful for learning. A have
reached for 6'th level (as beginner).

Now my code looks as following: http://good.net/_5pJ5Rurvz .
I can't understand issue: if i call in method:
    def roam_to_combat!
      debug("Entering roam_to_combat")
      state = :ws_combat
      @ini_health = health
      debug(@ini_health)
      warrior.attack!(cur_dir)
    end

then it lacks to execute string "state = :ws_combat".
But if i call
    def roam_to_combat!
      debug("Entering roam_to_combat")
      self.state = :ws_combat # <-- here is difference
      @ini_health = health
      debug(@ini_health)
      warrior.attack!(cur_dir)
    end
then it executes "state = :ws_combat" normally.

Why it didn't execute "state =" without "self"?
Is it Ruby's bug?
I got Ruby 1.8 installed.

state = :ws_combat

is an assignment to a local variable. You are not using the variable
in the method, so i assume this is not what you want. When you do

self.state = :ws_combat

you are calling the method state= on the object, which I suppose you
have (maybe created by attr_accessor).

The fact that you have to call it this way is to disambiguate between
a local variable assignment and a method call with implicit receiver.
This is a consequence of the syntactic sugar that allows you have
methods name xxx= that look like assignments.

Jesus.

I dunno as I haven't played with the code yet, but you're calling rest! on a Turn, not on the Warrior. Make sure your warrior variable (or method call result?) is what you think it is.

Make sure you still have something like:

  class Player
    def play_turn(warrior)

You just can't warrior.rest! on level 1, warrior methods are added level by

level.

And, why would you rest when you can just go straight ahead? :wink:

Yes, "state" is assignment method. It behaves unsimiliar as other
languages:
"xxx=" can be declared in Object Pascal too, for example.
It seems local variable "state" has overriden my method "state".
This can be a source of many hidden bugs for those who well-skilled in
Delphi or C++.
Why Ruby doesn't give me any warning?

state = :ws_combat

is an assignment to a local variable. You are not using the variable
in the method, so i assume this is not what you want. When you do

self.state = :ws_combat

you are calling the method state= on the object, which I suppose you
have (maybe created by attr_accessor).

Yes, "state" is assignment method. It behaves unsimiliar as other
languages:
"xxx=" can be declared in Object Pascal too, for example.
It seems local variable "state" has overriden my method "state".

Yes, that's exactly what happens. The parser flags state as a local
variable, and not state= as a method call.

This can be a source of many hidden bugs for those who well-skilled in
Delphi or C++.
Why Ruby doesn't give me any warning?

I don't know.

Because it doesn't parse incorrectly; it just runs incorrectly. That's
why you need to do what Jesus explained.

Well, what do you have in front of you? nothing, so you just need to
warrior.walk!
You'll get the feel method later, you don't need it yet as there is no
enemy. (enemies will be shown on the map)
