Entity and Vertex

dany67300

Hi everybody,

for my first message, I've got a problem in Sketchup and Ruby.
I'm trying to modify some Vertex position, I access them through the vertices method in the edges, so myVertex is a Vertex

				
if myVertex.is_a?(Sketchup;;Vertex)
     puts "Vertex"
     if myVertex.is_a?(Sketchup;;Entity)
          puts "Entity"
     end
end
			
if myVertex.is_a?(Sketchup;;Entity)
     Sketchup.active_model.selection.add myVertex
end

this show me in the ruby console :

Vertex
Entity
Error; #<TypeError; wrong argument type (expected Sketchup;;Entity or Array of Sketchup;;Entity)>

when i try to add it to the selection.
so I've got a Vertex which is an Entity, and it says me that it's not an Entity (with the error)

Can somebody explain me this symptom please ?
thanks

(sorry for my english)

Technically a Vertex is an Entity, but SketchUp can't select vertices - it does not have such a feature.
It's why I made Vertex Tools.

That error message you got simply isn't accurate enough.

ok thank you for your fast answer.

I'll try to fit my needs into antoher way, your Vertex Tools looks great, but it isn't adapted for me.

What is it you are trying to do?

I just wanted to put the vertex in the selection for drawing considerations, but I'll do it in an other way.

For that you can use the Tool class, just draw an indicator of the vertex you are manipulating.

For the moment, I'm trying to found a memory leak when I try to send my mouse coordinates to a Webdialog for displaying it using the InputPoint class and the position method. It takes me a lot of memory and then makes sketchup very slow.

This is odd - do you have some sample code we can look at?

dany67300

		#quand on bouge la souris
		def onMouseMove(flags, x, y, view)   
			#mise à jour du point deplace
			@input.pick view, x, y	
			
			update
			
			view.invalidate
		end
		
		def update
			pt = @input.position
		end

it looks like this with some javascript call in the update function

but when I comment them, there is still the leak. If you move a lot your mouse, you'll see the bug
