A bunch of RGSS questions.

[Kadoba]

I haven't posted in a while so I have a lot of questions built up. Here goes:

1. How do you continue a single script command on multiple lines?

2. There is a "rect" object for Bitmaps, is there any way to create a "circle" object? Or some way to fill a circular area on a bitmap with color? Or, to even further push the question is there a logical way to select a random pixel given a radius and an origin point? (ex, I want to select a random pixel location that is a radius of 20 pixels away from 150, 150.)

3. Is there a working particle script for rgss?

4. I don't quite understand the Window_Command Class. I have tried looking up some guides but the few I have found wasn't very helpful.

5. What is the newline special character in ruby?

6. How do I display damage display numbers outside of battle?

Sorry, I hope that wasn't too much for one thread. I appreciate the help in advance.

1. Please elaborate on this question
2. There is no Circle object, but you can easily make one yourself.

class Circle
  def initialize(x, y, radius)
    @x, @y, @radius = x, y, radius
  end
  attr_accessor :x, :y, :radius
end

3. There is. Search around for it.
4. Window_Command is easy. What part of it don't you understand?
5. "\n"
6. RPG::Sprite has a damage method. Look into it with the Help File.

Thanks Yeyinde. But a lot of your answers only partially answered by questions.

1. To elaborate on my first question, let's say I had to make this command for some reason:

p "This is a very long string that I wish to print in one long command, however I find it very frustrating that I have to scroll horizontally to read all of it, so I wish to make the command several lines of code longer.";

2. While I know how to create a class and initialize data, I don't know how to make the class "act" like a circle. Like for example, let's say I want to make a perfectly circular area on a bitmap completely blue.

3. Thanks. Helpful, but not without work. You know how to answer a question.

4. Basically I don't understand how to use it. I have tried to analyze the class but I cant seem to figure out how to make it work. I know it may seem simple to you but I haven't had much experience with windows and graphical computer functions. Because of this, the nature of such things confuse me. While I understand how a command window would work, and I'm pretty sure I could code my own. I cannot see how to use the already built in one.

5. I have tried "\n", but for some reason it doesn't work with the "p" function. It simply spits back out those exact characters.

6. Excuse me I figured this out, and I am ashamed at how simple it was.

1. Use print instead of p. p is used for display arguments in a readable format. When you have the print and the string, add some NewLine characters to break it up.

2. You need a series of fill_rects. I don't know how to work with Radians, so I can't help you with circles.

3. Here is an example on how to use Window_Command

class Scene_WC_Test
  def main
    @command_window = Window_Command.new(160, ['Command0', 'Command1']
    Graphics.transition
    loop do
      Graphics.update
      Input.update
      update
      break if $scene != self
    end
    Graphics.freeze
    @command_window.dispose
  end
  def update
    @command_window.update
    if Input.trigger?(Input::C)
      $game_system.se_play($data_system.decision_se)
      case @command_window.index
      when 0
        print 'Command0 Selected!'
      when 1
        print 'Command1 Selected!'
      end
      return
    end
  end
end

5. Use print instead of p

I'd just like to add something for the first question.

You can have anything on mutliple lines but only in a certain way :

variable =
"hello, this is a string!" *
3 +
" I think 3 of it is enough, right?"
p variable # "hello, this is a string!hello, this is a string!hello, this is a string! I think 3 of it is enough, right?"

If the line ends with an operator, an opening array or hash, etc..., the interpreter will check the next line.

Ok, thanks, I understand everything now. The only thing I still have a question on is about the circles, which now I am thinking is more trouble than it is worth. Thanks, both of you.
