props.scene.find

[frpaulas]

I don't understand the following behavior...
when my props.rb is...

__ :name => "screen"
buttons do
newdate :text => "New", :width => "25%"
thisweek :text => "This Week", :width => "75%"
end
display :id => "display", :text => "Welcome"

and players file newdate.rb is...

def self.extended(prop)
prop.display = prop.scene.find("display")
#prop.display.text = "WHAT"
puts "PROP nil?: #{prop.display.nil?}"
end

prop.display.nil? yields true
but when the props.rb is...

__ :name => "screen"
display :id => "display", :text => "Welcome"
buttons do
newdate :text => "New", :width => "25%"
thisweek :text => "This Week", :width => "75%"
end

prop.display.nil? yields false.
I would have expected both to yield false.
what am I missing?

Thanks for your help

The reason the display is nil the first time is because the new_date prop is being built on the screen before the display.  In the second version of the props.rb file, the display is already on the screen when the new_date prop gets extended.

Also, what is the reasoning behind using self.extended?

OK, I think I get that.

The reason for the self.extended: I wanted to click on a button and change the content of another existing prop.

Clearly I am floundering around here, but I see great utility here in Limelight, so I am anxious to figure it all out.

To do this, you need to implement the button_pressed or mouse_clicked method on the player you are clicking.  You use button_pressed if it's a prop with the player of button.  Otherwise, you use mouse_clicked.

module Newdate
  def mouse_clicked(event)
    scene.find("display").text = "New Text"
  end
end

If you look at the Limelight Docs Production, the players walkthroughs might give you more info.  There is also a section in the RDoc for the Button module.  (Limelight::Builtin::Players::Button)

I will SWEAR that was the first thing I tried and would get nil for the find, but I tried it again and it works fine.
MANY thanks!

On another topic: can the output interpret textile if I require redcloth (or similar)?

Hi Paul,

No, neither textile nor redcloth are supported. But that's an interesting idea. We'll think about it.
