[Code] Rantexpos

[thomthom]

hey guys. first up, i dont take credit for that plugin. its by axel lee. i found this plugin rantexpos at http://rhin.crai.archi.fr/rld/plugin_details.php?id=324

it doesnt seem to work in su 8. can one of you look into it and maybe correct it? i'm not into coding but really need this to work.

its supposed to randomize the texture position of the selected group/faces.


code is as follows.

Code: Select all

def rantexpos
   Sketchup.active_model.start_operation("RANTEXPOS!")
   selected = Sketchup.active_model.selection   
   for ent in selected
      if( ent.is_a? Sketchup::Face )
         tex = ent.material
         texpoint = []
         texpoint.push [rand(2048), rand(2048), rand(2048)]
         texpoint.push [rand(2048), rand(2048), rand(2048)]
         texpoints = [texpoint[0],texpoint[1]]
         ent.position_material (tex, texpoints, true)
         ent.position_material (tex, texpoints, false)
      end
      if( ent.is_a? Sketchup::Group )
         for fac in ent.entities
            if( fac.is_a? Sketchup::Face )
               tex = ent.material
               texpoint = []
               texpoint.push [rand(2048), rand(2048), rand(2048)]
               texpoint.push [rand(2048), rand(2048), rand(2048)]
               texpoints = [texpoint[0],texpoint[1]]
               fac.position_material (tex, texpoints, true)
               fac.position_material (tex, texpoints, false)

            end
         end
      end
   end
   Sketchup.active_model.commit_operation
end


filename="rantexpos.rb"

if !file_loaded?(filename)
   plugins_menu = UI.menu("Plugins")
   if plugins_menu
      plugins_menu.add_separator
      plugins_menu.add_item("Randomize texture positions") {rantexpos}
   end
   file_loaded(filename)
end


thanks in advance.

it doesnt seem to work in su 8.

Parenthesized argument lists for methods. (And remove a few spaces when they were in between method names and arg lists. This causes an error in Ruby 1.8.6)
Wrapped in a module.
Added Constants at top for setting menus.

Code: Select all

  TOPMENU = 'Plugins' unless defined?(TOPMENU)

  # Enter a string in the quotes to create a submenu:
  SUBMENU = "" unless defined?(SUBMENU)

  Filename = File.basename(__FILE__).downcase

thanks dan for looking into it. when starting sketchup i get an error now:

"Error Loading File rantexpos.rb
undefined local variable or method `filename' for AxelLee:Module"

and still when i start the plugin from the plugins menu su crashes.

Hi,

Typo: replace: file_loaded(filename) with: file_loaded(Filename)

Typo: replace: file_loaded(filename) with: file_loaded(Filename)

Done. Edited the code.

I did that in a secs just before bed. I have not tested it. (I assume it worked under Ruby 1.8.0, and didn't under 1.8.6 because of spaces between method names and argumentlists, etc.)

and still when i start the plugin from the plugins menu su crashes.

I was able to get it to work on a simple model (attached.)

SaucePan.skp

I was also able to get a BugSplat! on a very complex old ver 7.1 model. I selected the terrian mesh, and tried it on that. (splatto!)

hey man this is awesome. i needed to make a cutting board like ikeas whole-wood boards and they consist of individual parts glued together... anyway: NICE ONE!
although i have another thing. the textures original rotation is changed and completely oriented in the other way. is it possible to not let the rotation change or choose whether it randomizes rotation at a given angle?

thanks again, this was a big help

greets,

I don't have time myself to work on this.

Um.. if you have control.. then it would no longer be random ?

but I did notice that when I ran it on a pavement texture on a bridge model, that the roadway became misalign with the bridge. (Looked terrible.)

[g.moggel]

figured it out. i just need to rotate my face/object to be oriented with the axis. then i can hit rantexpos and it aligns them in the other way. thanks again for your help.
