Launch animation

TIG

A few points...
Use @xg which is specific to that instance of your class... and NEVER use $xg which would be global to ALL scripts loaded...
To keep it going reset @xg=0 if @xg>pages.length-1 - so it never ends... remember that an array starts at 0 so you need the -1 when doing a comparison .....

This proposed feature by inteloide should be integrated by default in the next Sketchup version. Having to click three times to play the animation is no good so I'll be keeping an eye when this plugin is done

inteloide

ok, by changing to :
@xg=0 if @xg>pages.size-1

all pages are activated, but without any break between each of them. (it's like it goes directly to the last page). How to implement a break ?
Also it doesn't loop : when the last page is shown, it stops (doesn't loop). Any reason why ?

Thanks again.
I will post my complete plugin when finish. Actually it's based on mover.rb plugin (to move components between pages) but I wanted to add a toolbar to have all tool within on click.

Read the Page section of the API.
page.delay_time gives the time to delay between pages [there is also transition_time], you could try using it/them between page changes, using a UI.start_timer(...){...} for each page ? [untested]...
If it's -1 you need to also get the model's page-options to find what the default value is...
Sketchup.active_model.options["SlideshowOptions"]["SlideTime"]
Sketchup.active_model.options["PageOptions"]["TransitionTime"]
etc

inteloide

Thanks TIG for telling me to look at Page API, because I thought it was only a collection (Pages) and not an entity.

So at the end, the solution I found is the following one :

def lire_anim (p) model = Sketchup.active_model pages = model.pages pages.selected_page = pages[p] if p<pages.size-1 then id = UI.start_timer(Sketchup.active_model.options["PageOptions"]["TransitionTime"], false) { lire_anim(p+1) } end end

and to launch : lire_anim(0)

Now, I need to find a way to stop animation while it's running...

TIG

You also need to understand view.animation= etc...
https://developers.google.com/sketchup/docs/ourdoc/view#animation=
Add this into your script's methods

animation = Anima.new()
 model = Sketchup.active_model
 view = model.active_view
 anim = view.animation=animation
 if (anim)
   UI.messagebox anim
 else
   UI.messagebox "Failure"
 end

To cancel the current view's animation use view.animation=nil

inteloide

I'm close to the aim !
I have 2 issues :
1-When start the animation it goes to "stop" subrouting but it doesn't stop animation ...?!
2-When setting view.animation to nil, it' doesn't stop... ?!

Again your help is welcome !

class Class_Run_Animation def initialize puts "Start of animation" show_scene(0) end def show_scene(p) puts "Go to scene #{p}" pages = Sketchup.active_model.pages pages.selected_page = pages[p] if p<pages.size-1 then id = UI.start_timer(Sketchup.active_model.options["PageOptions"]["TransitionTime"], false) { show_scene(p+1) } return true else puts "End of loop" return false end end def stop puts "Loop stopped" return false end end

TIG

You loop through the pages and then return false, this stops it, you never call stop, and don't really need to...
You should only use the initialize() method to set up @ variables etc, if needed...
You have dropped the def nextFrame(view)... Why? I think this is confusing the issue... Using it would let you create an animation class object that you could assign to the view [looping through the scenes [pages] etc] in some separate code with view.animation=Class_Run_Animation.new(), then you can later cancel with view.animation=nil.
The separate code used would be something like:

module Inteloide
  def self.start_animation()
    Sketchup.active_model.active_view.animation=Class_Run_Animation.new()
  end
  def self.end_animation()
    Sketchup.active_model.active_view.animation=nil
  end
end

Used in the console [or added to a toolbar command] as
Inteloide.start_animation
and
Inteloide.stop_animation
Your earlier code could be readily adapted to do this...

inteloide

ok, I changed to an animation class, but it still don't stop
I think the issue comes from the start_timer which start the procedure even if animation is stopped.

` class Class_Run_Animation
def initialize
puts "Start of animation"
#show_scene(0)
@p=0
end

def nextFrame(view)
puts "Go to scene #{@p}"
pages = Sketchup.active_model.pages
pages.selected_page = pages[@p]
if @p<pages.size-1 then
@p+=1
id = UI.start_timer(Sketchup.active_model.options["PageOptions"]["TransitionTime"], false) { nextFrame(view) }
return true
else
puts "End of loop"
return false
end
end
end

module Inteloide
def self.start_animation()
Sketchup.active_model.active_view.animation=Class_Run_Animation.new()
end
def self.stop_animation()
Sketchup.active_model.active_view.animation=nil
end
end`

You've made it iterate itself!
Try something like this...


def initialize()
  @model=Sketchup.active_model
  @pages = Sketchup.active_model.pages
  @po=@model.options["PageOptions"]
end
def nextFrame(view)
  while view
    @pages.to_array.each_with_index{|page, i|
      next unless page.name==page.label ### (SKIP)
      puts page.name
      @pages.selected_page = @pages[i]
      UI.start_timer(@po["TransitionTime"],false){###}### wait for a time
    }
  end#while
end

or similar...

inteloide

Well, I'm lost ;o)

what is the aim of this loop :
@pages.to_array.each_with_index{|page, i|
next unless page.name==page.label ### (SKIP)

what do you put instead of "###" in the code :
UI.start_timer(@po["TransitionTime"],false){###}
(I put nextFrame(view) because if not the animation doesn't continue)

inteloide

Maybe it's because I don't understand how sketchup makes the loop for an animation, what's happen after nextframe is called and run ? I'm lost in fact.... (

TIG

Maybe I confused you with the addition of
next unless page.name==page.label ### (SKIP)
All this does is NOT display the page IF the name and label don't match.
A page's name and its label are the same UNLESS the page has be marked NOT to be included in the animation in the Scene-Manager dialog - it then has the name labeled inside () - so you won't show it...
The ### is a 'rem' statement - a 'comment' after the code so what follows is ignored...

The next part:
puts page.name
simply displays the name of the scene it's processing in the Ruby Console
Then:
@pages.selected_page = @pages[i]
sets the selected page to be the current pages 'item' [by index 'i'] in the list of pages...
Next:
UI.start_timer(@po["TransitionTime"],false){###}### wait for a time
The timer starts a pause - the rem ### at the end is as above...
ON reflection... I appreciate that this final part is wrong.
Because the timer then runs outside of the main loop !
Perhaps using:
sleep(@po["TransitionTime"])
instead, might work instead ?? This stop processing for that long before the next page is set 'selected'.

Hi,

I didn't saw your answer but I produced this code...
I post it for your information...but I will work on your answer

So, my code, as it is now (please don't blame me using a global variable... )

` class Class_Run_Animation
def initialize
puts "Start of animation v1"
@p=0
@id=0
end

def nextFrame(view)
if $inteloide_cont==true then
puts "Go to scene #{@p}"
pages = Sketchup.active_model.pages

  pages.selected_page = pages[@p]
  if @p<pages.size-1 then
    @p+=1
    @id=UI.start_timer(Sketchup.active_model.options["PageOptions"]["TransitionTime"]+Sketchup.active_model.options["SlideshowOptions"]["SlideTime"], false) { nextFrame(view) }
    return true
  else        
    puts "End of loop"
    return false
  end
else
  puts "stop animation"
  @id=UI.start_timer(1, false) { nextFrame(view) }
end

end
end

module Inteloide
def self.start_animation()
$inteloide_cont=true
Sketchup.active_model.active_view.animation=Class_Run_Animation.new()
end
def self.stop_animation()
$inteloide_cont=false
Sketchup.active_model.active_view.animation=nil
end
def self.pause_animation()
$inteloide_cont = !($inteloide_cont)
puts $bg_cont
end
end`
