    ... I might have a look later, not enough time to look through the whole thing right now though ๐Ÿ˜† .

    Also, I've been trying to figure out how to implement mouse control in ruby script; I think Chris Phillips might know a thing or two (considering how much mouse interaction there is in sketchyphysics), but if there's anyone else out there that could help out at explaining what do do, that would be great.

    So far, all I know is that it would involve def onMouseMove(flags, x, y, view) (view is model, which is Sketchup.active_model, .active_view), aswell as def onLButtonDown(flags, x, y, view), def onLButtonUp(flags, x, y, view) and def draw(view). Or at least I THINK those are what I need to use.

    Anyways, if anyone knows how, I would really appreciate it if you could explain a bit, or if it's in the tutorial (which I haven't been able to look at yet), that would work too ๐Ÿ˜†

      That is not in the turorial, but it will be in a future one I hope. The idea there is implementing a tool class in your script. I can write up a quick start template, but I can't get too in depth right now. Hopefully alter in a tutorial though.

      Chris

      PS I think the tutorials are open to anyone to write at this point. If aynone out there wants to do a better on, or do one on a different topic, they are more than welcome to go for it! I think we might need a new tutorial template though for Ruby tutorials. The current one is very little text and very much image - not ideal for Ruby. Maybe I'll outline what I think a Ruby tutorials might need, and then see if Coen has time to implement it eventually.

                    Thanks Chris
                    I have really always wanted to give it a try, or at least understand Rubys in greater depth.
                    Thanks for the effort.

                      Thanks for the great comments, I hope it gets more people interested in beginning. I'm sure there are other roads to take to get into Ruby, but thats how I did it, so its the only way I can explain. Hopefully it will be logical enough for others to use too.

                      Malaise, sorry the font is small. If you click on most of the images, it shows a full size image. But if the full size image is too small also...hmm. I don't know. I bet I could also provide a link to the .rb script for download right up front, for people who can't read the images very well.

                      But if I provide the link to the text script, its not a free pass to just copy and paste ๐Ÿ˜„

                        @BTM (and anyone interested) I did go ahead and write up a quick tool script that creates a tool, which is how you get the onmousemove and all other tool methods to work. Check it out here:

                          Chris,

                          Thanks for making a ruby tutorial.

                          Its always inspiring to look at someone else's code.

                          Here is a version which use a hash instead of arrays to count all entities types;

                          
                          def count_entities
                          	model = Sketchup.active_model
                          	entities = model.entities
                          	count = {} # start a new hash
                          	entities.each do |e|
                          		stype = e.typename
                          		# start new count, or add 1 to existing count
                          		count[stype] = count[stype] ? count[stype] + 1 ; 1
                          	end#loop
                          	sorted_keys = count.keys.sort
                          	sorted_keys.each do |key|
                          		printf("Total %-12s; %5d\n", key, count[key])
                          	end#loop
                          	return nil
                          end#def
                          
                          

                          The weird line:

                          count[stype] = count[stype] ? count[stype] + 1 : 1

                          would be easier to read as

                          
                          if (count[stype])
                              count[stype] = count[stype] + 1
                          else
                              count[stype] = 1
                          end#if
                          
                          

                          Keep up the good work
