How to recognize cursor on top of texture?

renderiza

Hi, I am about to finish my next update for Canvas plugin but I am having trouble with cursor on top of texture. Here is link to Canvas... http://sketchucation.com/forums/viewtopic.php?f=323&t=51655

So Far I have this done;

Add:: On Vertex
Add:: On Edge
Add:: On Face
Add:: Group
Add:: Component
Add:: On Image

But I still trying to finish these;

Add:: On Texture - Can't solve it at the momment
Add:: On Shadow - (I made a thread asking this and I am close to finishing it...just need little more time)
Add:: On Selection - (Have not tried yet so don't know if I will have problems)

I tried this;


def onMouseMove(flags,x,y,view)

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

select_comp=view.pick_helper
select_comp.do_pick x,y
selected_comp=select_comp.best_picked

 if flags == 1 && @@sel != nil && @@texture_addon == true && selected_comp.is_a (Sketchup;;Texture) == true
   add_object(point) ;
 end 
end #def

Thanks in Advance!

Here is a WIP

I managed to recognize the material by doing this;

select_comp=view.pick_helper
select_comp.do_pick x,y
selected_face=select_comp.picked_face
selected_face_mat=selected_face.material

# Add On Texture 	
if flags == 1 && @@sel != nil && @@texture_addon == true && selected_face_mat != nil
	add_object(point) ;
end

Now I need see how I can integrate texture material in there....wish me luck!

I feel weird replying to my own posts but I solved it!

Just need to add .texture at the en of selected_face_mat like this...selected_face_mat.texture


select_comp=view.pick_helper
select_comp.do_pick x,y
selected_face=select_comp.picked_face
selected_face_mat=selected_face.material

# Add On Texture    
if flags == 1 && @@sel != nil && @@texture_addon == true && selected_face_mat.texture != nil
   add_object(point) ;
end

Cheers!

That won't work if the face have the default material - in which case selected_face.material will return nil - and you can't call nil.texture

Also - no need to do: selected_face_mat.texture != nil
nil evaluates to false and any other value evaluates to true.

For the Canvas Plugins now have this two Add:: On Features;

Add:: On Material - I am actually happy that the default material returns nil because it may pass as a mask feature

Add:: On Texture - This one is working as it should at the momment adding groups or Coponents on top of entities with textures only and ignores any kind of entities with material color only & no texture image.

But this line will cause an error:
if flags == 1 && @@sel != nil && @@texture_addon == true && selected_face_mat.texture != nil

If selected_face_mat is nil then you cannot call .texture on it.
