Materials again

kiesewetter

me again...

i don't know why, but the attribut "ablauf", "material" always receives a new value, even if the face's material is included in the array called invalid_material. i'll post the code, because i realy don't know how to fix it.

    
ents.each{|e|
          if e.typename == "Face"
             start = e.get_attribute "ablauf", "baubeginn"
             ende = e.get_attribute "ablauf", "bauende"
             if (e.material)
               invalid_materials = ['bau_mat', 'fertig_mat', 'inplanung']
               unless invalid_materials.include?( e.material.name )
                 mat_vorher = e.material.name
                 e.set_attribute("ablauf", "material", mat_vorher)
               end
             end
                     
                     
          if @woche.to_i >= start.to_i && @woche.to_i < ende.to_i
            e.material = bau_mat
          end
          if @woche.to_i >= ende.to_i
            e.material =fertig_mat
          end
          if @woche.to_i < start.to_i
            e.material = inplanung
          end
       end
                     
        }
   

    #now the code that reloads the material

    def mat_back
       mod = Sketchup.active_model
       ents = mod.entities
       mats = mod.materials
       default_mat = mats.add "standardwert"
       default_mat.color = [50,250,50]
       ents.each{|e|
                  if e.typename == "Face"
                    if (e.get_attribute "ablauf", "material")
                      mat_temp=e.get_attribute "ablauf", "material"
                      e.material=mats[mat_temp]
                    else
                      e.material=default_mat
                    end
                  end
                 }


    end

To check the materials' name make the line
p mat_vorher = e.material.name
Then it will print the name of the material in the [opened] Ruby Console to compare with your invalid_materials list...
Looks like they don't match ?

kiesewetter

it was my mistake. the materials were declared in a tool as a local variable. every time the tool was invoken, the materials werde declared. so to the materials name was a number added, because the material already existed in the materials container. when you only once invoke the tool everything is fine. one more an it didn't work.

is it possible to declare a material as a constant or to declare it with an "@" in a class to avoid that?

thomthom

Why not just check if the material exists?

TIG

For example:


if mats["standardwert"]
  default_mat = mats["standardwert"]
else
  default_mat = mats.add("standardwert")
  default_mat.color = [50,250,50]
end

kiesewetter

it works. thanks a lot, once more

tommorow t'll try to declare the material in the constructor of the class anyway, to avoid putting all the trash in the memory.

bye.
