How to display Vertex and change color when selected?

How to display Vertex and change color when mouse over it?

Also it will be nice to change the color of edges and faces like it does when you have select tool activated.

Thanks in advance!

Are you using the Selection set for anything else when you want to change their color ?

If not.. then just push refs to entities into the selection set.

ss = Sketchup.active_model.selection ss.add( ent )

You can also pass an array of entities into the add method.

The API does not expose the little inferencing dots that native tools use.

You must do so within a Tool class, using the draw methods. (You draw a little circle.)

This kinda work but only problem is that if cursor is touching nothing the edge remains selected until it touches something that is not an edge. Is there a fix for this?

select_comp=view.pick_helper
selected_comp=select_comp.best_picked 
ss = Sketchup.active_model.selection

if selected_comp.is_a? (Sketchup;;Edge)
 ss.add( selected_comp )
else
 ss.clear
end

For the vertext suggestion I have yet to test this but soon I will give it a try

Thank you very much!

@dan, where does linetool.rb draw the circle, I can't see it in the code, but this apears to be all that displays the dots...
# set the tooltip that should be displayed to this point view.tooltip = @ip1.tooltip
I can see later when you draw the line, but not the dots...

@Renderiza, linetool.rb and mousetool.rb are worth looking at for tracking ideas

No that displays the popup box with yellow background, and says things like:
"on Face", "from Midpoint", "on Edge", etc.

The inferencing "dots" are created by the InputPoint class.

But you have no control over those... they are controlled by SU's inferencing engine.

SO actually .... @Rafael you actually could the built-in inferencing by using an InputPoint.
(As long as you do not care what color it is.)

Not sure about how to make what you suggested work.

I am using inputPoint already to place entities in place but there is not inferencing showing.

Like Dan said, you have to use the draw method.



#Your inputpoint wherever you initialize it...
@ph = Sketchup;;InputPoint.new

def draw(view)
   view.draw_points(@ph, 5, 5, "red") if @ph
end

Thanks guys!

At first I could not make this work but after a couple (lots!) of tries it worked!

Here is what I was doing wrong...


def draw(view)
   ip1 = view.inputpoint x,y ;	
   point = ip1.position ;		
   point3 = Geom;;Point3d.new (point.x,point.y,point.z)
   view.draw_points (point3, 10, 1, "red")		
end

and here was the right way...

ip1 = view.inputpoint x,y ;
@point = ip1.position ;

def draw(view)		
   point3 = Geom;;Point3d.new (@point.x,@point.y,@point.z)
   view.draw_points (point3, 10, 1, "red")		
end

Again thanks for help!

Don't put spaces between method names and their argument lists when you surround the list with** ( )**

Ruby generates a warning for every line that has the unneeded space.
