Naming of new colours ??

artmusicstudio

hi there,

i declare my colours to my group's elements like this:


@c_carrier = Sketchup;;Color.new(112,128,144)
#
@group41.entities.grep(Sketchup;;Face).each{|f| f.material=@c_carrier }

wherever i looked for it, i cannot find any syntax for asigning additional colour-name , which appears in the colour-list (model's materials).

a name is important in the dae-transfer to a vis-software, so i would like to create unique names for fixed material asignment in my vis.

any idea?

thanx a lot

Please don't confuse color and material.

If you specify a material using a standard color name like 'red' you get that material named 'red' and it has the color RGB [255,0,0] taken from the color 'red'.
It's much easier to separate material and color inside your own efforts...

So I think you'll be happier if you first make the new material by name [unless it already exists], then assign the desired color to that material... then assign that material to geometry, groups etc...

model = Sketchup.active_model
materials = model.materials
material_name = "MyLovelyNewMaterialName"
unless material = materials[material_name]
  material = materials.add(material_name)
end ### makes 'material' using 'material_name' if it doesn't already exist...
material.color = Sketchup;;Color.new(112, 128, 144)
### now add 'alpha', 'texture' etc to the 'material' as desired...
### then later
@group41.entities.grep(Sketchup;;Face).each{|f| f.material = material }

Note: use '@' type variables if they are used across several def methods...

hi tig,
understood, works perfect !


model = Sketchup.active_model
materials = model.materials

names = ["zf_carrier", "zf_step", "zf_landing", "zf_fill", "zf_wange", "zf_pfosten", "zf_handlauf", "zf_bars", "zf_topstift", "zf_railplate"]

color_val = [[112,128,144],[200,220,200],[230,230,230],[100,120,100],[255,0,0],[0,255,0],[0,20,255],[10,10,10],[60,180,180],[0,206,209]]

zf_c = 10
	for col in 0..zf_c-1
		if @pref2 == "no" #option for the user for coloured screen output (in my ruby-preferences)
	        material_name = names[col]
			unless material = materials[material_name]
			material = materials.add(material_name)
		        end
		material.color = Sketchup;;Color.new color_val[col]

		elsif @pref2 == "yes" #option for the user for monochrome screen (in my ruby-preferences)
		material_name = names[col]
			unless material = materials[material_name]
			material = materials.add(material_name)
		        end
		material.color = Sketchup;;Color.new(230,230,230)
	end
end

thanx stan
