Moving 3d text

kiesewetter

Hallo!
I'm trying to write a script that creates a list of 3d texts. One 3d text should be diplayed, then it should be moved (in negative y-direction), then the next 3d text should be created and so on.
With my code the Translation of the text doesn't work.
Here is the code:


y_text=0
zaehler=0 #counter
textarray=[]
@bauabschnitte.each{|b|
                     tr = Geom;;Transformation.new [0,y_text,0]
		     anzeige =  b.getname #the text the should be displayed by the 3d text
                     textarray[zaehler]=ents.add_3d_text anzeige, TextAlignRight,"Arial",false,false,10,5,0,true,1
		     ents.transform_entities tr, textarray[zaehler] #here the 3d text should be moved...
		     y_text = y_text-15
		     zaehler = zaehler+1
		    }

Thanks for your time.

Initially 3D text is always placed at the ORIGIN = [0,0,0]
Your code sets a new point as a tr-ansformion = [0,y_text,0]
BUT you have just set y_text=0
SO it won't move as you transform it to the same point !!!
You then reset y_text = y_text-15 BUT that's after the tr-ansformation was invoked!!!
Set a point that isn't [0,0,0] and you will see the 3D text move!!!!!!!!!!!!!!!

Hi,
TIG, good point, quite obvious

@unknownuser said:

tr = Geom::Transformation.new [0,y_text,0]

Better like this: tr = Geom::Transformation.new([0,y_text,0])
or: tr = Geom::Transformation.translation([0,y_text,0])
Always put arguments within parenthesis, such as:
textarray[zaehler]=ents.add_3d_text(anzeige, TextAlignRight,"Arial",false,false,10,5,0,true,1)

Tschüss

The translation should be done with the elments of the array @bauabschnitte exept the first one.
So y_text is set to 0 at the beginning an gets raised every time the code passes the "each" part.

Here is the error-message that appears in sketchup every time I load the code:

Error: #<TypeError: C:/Program Files/Google/Google SketchUp 8/Plugins/klasse_ausgabe.rb:253:in transform_entities': wrong argument type (expected Sketchup::Entity)> C:/Program Files/Google/Google SketchUp 8/Plugins/klasse_ausgabe.rb:253 C:/Program Files/Google/Google SketchUp 8/Plugins/klasse_ausgabe.rb:253:in balkendiagramm'

C:/Users/tim/Desktop/test_balkendiagramm.rb:5

The first 3d-text is created at the origin. So I don't know what to do.

def texter
    model=Sketchup.active_model
    ents=model.active_entities
    y_text=0
    zaehler=0 #counter
    @bauabschnitte=["Dog","Cat","Mouse","Spider","Fly"] ### TIG faked up 'name' list here***
    textarray=[]
    @bauabschnitte.each{|b|
        anzeige =  b ###b.getname #the text the should be displayed by the 3d text - 
        ###***what is 'b.getname' ?  If 'b' is a component then use 'b.name' ???
        gp=ents.add_group() ### must group 3D text
        gp.entities.add_3d_text(anzeige,TextAlignRight,"Arial",false,false,10,5,0,true,1)
        tr = Geom;;Transformation.new(Geom;;Point3d.new(0,y_text,0))
        textarray[zaehler]=gp ### add gp to array
        ents.transform_entities(tr, textarray[zaehler]) #here the 3d text should be moved...
        y_text = y_text-15
        zaehler+=1 ### increment counter
    }
end

This works type 'texter' to run. When you make a piece of 3D text it returns 'true' if successful so your array was 'booleans' NOT 'entities'. Here I add the 3D text to a group and THEN add the group to the array, that way you CAN transform the group as needed...

works . thanks a lot.
