Mathematics related problem

Perhaps I am just a raw beginner myself but it appears that in his original snippet meeta is setting @M = bending.

Shouldn't that be @M = result?

Inputbox does not alter the input default value that I can see.
therefore bending will still be 0.0 after the input.

yes your absolutely true.. i corrected that in my code and yet its showing the same results.. and besides if it were to be 0 then @M / 'anything ' = NaN? there is some problem there.. but I got a newer problem after sorting that out.. this is more interesting i reckon.. please have a look at this

@b = 300
      @h = 280
      weight =((25.0*@b*@h) / 10**6)
      prompts = ["Variable Load(kN/m) ", "Permanent Load(kN/m) ", "Max Moment known(Nmm)"]
      loads = [0.0, 0.0, 0.0] #At this point enter 21, 50.1 and 0
      results = inputbox prompts, loads, "Loads apart from Self-weight/ Or if moment is known, Please enter"
      variable_load, permanent_load, moment = results
		
		if (moment != 0) 
			@M = moment
		else
			uls = (1.35*variable_load + 1.5*permanent_load + 1.5*weight)*@length
			UI.messagebox(@M)
			UI.messagebox(weight)
			UI.messagebox(results)
			@M = 0.11*uls*@length 
			@shear = 0.60 * uls 
			UI.messagebox(uls)
			UI.messagebox(@M)
		end

I don't know why, the weight that it should be showing is 2.1, but its showing 0.0032 something at the very beginning of the code.. its really taking a toll on me now! I know that many UI boxes is absolutely silly but that's my way of debugging because I know no other way! pls recommend any other method for debugging!

Output the values to the Ruby Console, use the puts method. puts "Hello World"

yes i tried doing that,, but strangely the answer in ruby is always right but not in sketchup! so i figured something must be wrong in the code or in sketchup! hopefully its my code because that'll be easier to fix

You are aware of the Ruby Console window in Sketchup, right? That's the one I'm referring to. That will let you see the values you get from the script running in SU's Ruby.

oh you mean that ruby console,, i thought you were talking of the interactive ruby console.. sorry about them.. let me try it out now!

thomthom

There are people that have worked out how to hook up debuggers to SU's ruby. But I've so far managed by using the Sketchup Ruby Console to output data throughout the script when I need to debug errors and abnormalities. It's the Sketchup Ruby Console that most people here on this forum will be referring to when they mention the Console.

meeta

ohh really? thanks i am newb with sketchup programming have been using sketchup for a few years though.. anyways now i wont look like a fool if anyone says console and i think of the irb! thanks

thomthom

For most people here, the Sketchup Ruby Console is the debugging tool. Some are also using Jim's custom console which has some extended features.

thomthom

FYI, I'd never used Ruby before I started making plugins for SU. And I only recently installed a normal Ruby installation on my computer - never touched a full Ruby installation before.

So there's no wonder we're getting confused here.

meeta

haha i see what you mean.. i ought to not touch the irb as well! i just downloaded and installed jim's web console.. its really good.. i dinno i could write and test the code in sketchup! i used to restart and edit it in msft notepad! not anymore.. always love increasing productivity :

thomthom

I write in Notepad++ and use the regular Console to debug. Reload the changes by typing load "rubyfile.rb" into the Console. Crude - but it works. Though there are cases where I really wish I could step through the code...

meeta

ahh notepad++ old friend.. i used to do my c++ programming on it and then take it to university to test it! haha
i think i am gonna take the night off and start over with this tomorrow might crack something.. good night world!
