Directly apply a material

[rossthompson]

Hi,
I am working on a script that activates the paint bucket tool with a predefined material of a certain colour and transparency. The code I have written works fine except on every use it creates a copy of the material eg. 'window1', 'window2' etc. which makes a bit of a mess of the materials palette.

I think it just needs a simple if statement to avoid creating the material if it already exists. Does anyone know how to do this?

Thanks Ross

toolbar = UI;;Toolbar.new "Window"
     cmd = UI;;Command.new("Test") { window }	
     cmd.small_icon = "CBG/window_sm.png"
     cmd.large_icon = "CBG/window.png"
     cmd.tooltip = "Paint Window"
     toolbar = toolbar.add_item cmd
     toolbar.show	 
	 
def window
 model = Sketchup.active_model
 materials = model.materials
 m = materials.add "Window"	 					# Adds a material to the "in-use" material pallet.

m.color = Sketchup;;Color.new(100, 150, 240)	# Specify the colour
color = m.color
alpha = m.alpha=0.5								# Set transparency

materials.current = materials["Window"]			# Set to the current material
Sketchup.send_action "selectPaintTool;"			# Start the paint tool
end

Try something like this:
m=materials.add("Window") unless m=materials["Window"]
Which sets ' m' to be an existing material named 'Window', but if it fails [ unless or should you prefer it use if not]... then it sets it to a new material named 'Window' [ add]...

Hi, that worked perfectly

Thanks TIG

Can also be written like so:
m = materials['Door'] || materials.add('Door')
