Checking wether material exists before declaring it

kiesewetter

Hallo!

I want to declare a material in a method, but before it's declared it should checked wether the material already exists to avoid overloading the memory with tons of the same material. Here is the code i used but it doesn't work so far...


def status_anzeigen 
  mod = Sketchup.active_model
  ents = mod.entities 
  sel = mod.selection 
  mats = mod.materials
  unless mats.include?("im_bau")
    bau_mat = mats.add "im_bau"
    bau_mat.color = [255,127,38] 
    fertig_mat = mats.add "fertig"
    fertig_mat.color = [211,211,211] 
    inplanung = mats.add"noch_nicht_angefangen"
    inplanung.color = [176,196,222]  
    inplanung.alpha = 0.3 
  end

#and so on

TIG

model=Sketchup.active_model materials=model.materials mat=materials.add("MyNewMaterial")if not mat=materials["MyNewMaterial"]
This test adds a new material named "MyNewMaterial" IF it doesn't already exist AND sets ' mat' to refer to it, whether it exists OR it has just had to be made...
