What am I doing wrong?

JaViXP

Hello,

well, I was just trying do make an 'addition' to Chris' multi-pushpull plugin and this is what I've got so far:

model = Sketchup.active_model
sel = model.selection
ent = model.active_entities

height = mpp_options_diag

faces = []
	sel.each do |e|
	
		if e.is_a? Sketchup;;Face
			faces << e
		end
	end
	
	faces.each do |face|
	face.pushpull height.to_i
end

def mpp_options_diag
	prompts = ["Insert the height for the Multi PushPull"]
	defaults = ["100"]
	input = UI.inputbox prompts, defaults, "Multi PushPull Tool Parameters"
end

Thing is, it lets me run the code if I do "face.pushpull(100)", but not with "face.pushpull height.to_i"

The Ruby Console shows this error:

undefined method `to_i' for ["100"];Array
C;/Program Files (x86)/Google/Google SketchUp 8/Plugins/webconsole/webconsole.rb;31;in `run'
(eval);15;in `each'
(eval);15;in `run'
undefined method `to_i' for ["100"];Array

What am I doing wrong then?
Thanks.

Hi Javier,

Ruby methods will return the value of their last statement. In your code, the method mpp_options_dialog return the value of the input variable; which is a Array.

So height == ["100"]. You need to get the first element of the Array. Here is one way:

height = height[0].to_i

Also you might not want the height as an integer by using .to_i, because 0.5.to_i will become 0 not 1 as you might have expected, as an integer simply ignores anything to the right of the decimal-separator !
The inputbox dialog can have its 'type' set to be a 'float' etc by making the default e.g. 1.0 [rather than 1 which fixes it as an integer] - then the dialogs returned_value[0] is always as a float anyway - BUT if you really want it to be a string - so for example the user can type ' 1.5m' and they'll get 1.5m irrespective of the SKP's current unit settings - then use .to_l to convert that value into a 'length'...

Rather than add your dialog into a lot of complex code to test it just make it in a one-liner in the Ruby Console...

results=UI.inputbox(["Height: "],[1.0],[""],"My Title")
for a float - shown with
answer=results[0], and answer.class

results=UI.inputbox(["Height: "],[1],[""],"My Title")
for an integer - shown with
answer=results[0], and answer.class

results=UI.inputbox(["Height: "],["1.0"],[""],"My Title")
for a 'string'- shown with
answer=results[0], and answer.class and then
answer.to_i answer.to_f answer.to_l

If you feed the inputbox a Length - then it will return a Length. No need for conversion. And the Length will even be displayed in the format of the model.

thomthom

result = UI.inputbox( ['Width: '], [10.m], 'Hello World' )
Type 50cm in the inputbox.
` > [19.6850393700787]

result[0].class

Length

result[0].to_s

500mm`

Thank you everyone, for "clearing up" my doubts. It works fine now.
By the way, just not to make a new topic for a single question, is is possible to load/unload/reload plugins with SketchUp running?

That is actually better to make a new topic. New topic of conversation - new thread. Makes it easier to navigate and browse. Also makes the threads easier to follow with less topics.

You can load (and reload) scripts by using the Ruby Console, typing load 'myRubyFile.rb'

Sorry to dig up an old thread but It's kind of relevant to what I'm trying to do with inputbox.

What I'd like to do is associate a word with a value... ie: inputbox prompts for 3 values to create a square, height, width and vertical line... height and width are pretty self explanatory. Vertical line is expressed as inches.. so a 24" x 24" square could be divided in half by typing in 12... what I'd like to add is being able to type in 'center' or 'middle' and getting the same result.

I've tried making that field of the array a string and then converting the string to an integer or a float but I just can't get it to work... also tried associating the words to a value and samething no workie...

Hope that makes sense...

Thanks in advance.

With some trial and lots of errors I figured it out.

Sorry we were so useless. Glad you figured it out, though!

Frankn

Trust me Chris you and everyone else who takes the time to help us new guys out are anything but useless.
