How to retrieve array of faces that are inside a group?

[renderiza]

Hi,

I want to fix my Animatex plugin to animate faces with textures even within a group but I can't manage to retrieve index of faces inside groups. Here is the Animatex forum just in case... http://sketchucation.com/forums/viewtopic.php?f=323&t=52238

Any help will be appreciated!

The only thing that comes to my mind is raytest but I hope there is an easier way.

try something like
faces = group.entities.grep(Sketchup::Face)

Hi,

I can't seem to iterate though all the groups to get all faces. Only can retrive faces if I use [0] or [1] in faces = group[0].entities.grep(Sketchup::Face) for only one group.

Is there a way to have something like group.each kinda thing?

model = Sketchup.active_model 
ents = model.entities 

group = ents.grep(Sketchup;;Group)
faces = group[0].entities.grep(Sketchup;;Face)

UI.messagebox faces

Again thanks TIG!

groups.each {} also works off course.

Thanks you Thomthom and TIG you both have been really kind in helping me out!

Hi,

Can I include both faces inside groups and faces out of groups in the same 'face=' variable?

model = Sketchup.active_model ;
ents = model.active_entities ;	

groups = ents.grep(Sketchup;;Group) ;
for group in groups
  faces = group.entities.grep(Sketchup;;Face)
end

How can I add this to the faces value above without overwriting it?

faces = ents.grep(Sketchup;;Face) ; 

Thanks!

[TIG]

model = Sketchup.active_model
ents = model.active_entities

faces = ents.grep(Sketchup;;Face)

groups = ents.grep(Sketchup;;Group)
for group in groups
  faces << group.entities.grep(Sketchup;;Face)
end

faces.flatten! ### combine []'s
faces.compact! ### remove 'nils'

### now you have an array of 'faces' in the model's active_entities AND inside all groups in the model's active_entities...

Thomthom the code above I though retrieved all faces from all groups but only does it for one. It acts like when I used [0], any ideas?

Let me test your suggestion TIG

Thanks!
See my post just before it uses array<< NOT array= and then a flatten! & compact!

[renderiza]

model = Sketchup.active_model ;
ents = model.active_entities ;   

groups = ents.grep(Sketchup;;Group) ;
for group in groups
  faces = group.entities.grep(Sketchup;;Face)
end

Thank you so much yet again!

Another variation on how to get all faces from multiple groups:

<span class="syntaxdefault"><br />model&nbsp;</span><span class="syntaxkeyword">=&nbsp;</span><span class="syntaxdefault">Sketchup</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">active_model<br />ents&nbsp;</span><span class="syntaxkeyword">=&nbsp;</span><span class="syntaxdefault">model</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">entities<br /><br />groups&nbsp;</span><span class="syntaxkeyword">=&nbsp;</span><span class="syntaxdefault">ents</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">grep</span><span class="syntaxkeyword">(</span><span class="syntaxdefault">Sketchup</span><span class="syntaxkeyword">;;</span><span class="syntaxdefault">Group</span><span class="syntaxkeyword">)<br /></span><span class="syntaxdefault">faces&nbsp;</span><span class="syntaxkeyword">=&nbsp;</span><span class="syntaxdefault">groups</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">map&nbsp;</span><span class="syntaxkeyword">{&nbsp;|</span><span class="syntaxdefault">group</span><span class="syntaxkeyword">|&nbsp;</span><span class="syntaxdefault">group</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">entities</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">grep</span><span class="syntaxkeyword">(</span><span class="syntaxdefault">Sketchup</span><span class="syntaxkeyword">;;</span><span class="syntaxdefault">Face</span><span class="syntaxkeyword">)&nbsp;}.</span><span class="syntaxdefault">uniq<br /></span>

The .uniq part is there just in case you have two groups that are copies of each other.

[TIG]

In my version you ought to add a closing
faces.uniq! ### to remove 'duplicates' if the groups have multiple copies

[renderiza]

Very grateful indeed!
