Inputbox issues

[Pixero]

I have a simple inputbox but I'm getting errors later in the plugin complaining @@depth to be an array so I tried adding a [1] but it doesn't seem to work.

@@depth = 400.mm unless @@depth

# Dialog box
prompts = ["Depth"]
values = [@@depth]
results = inputbox prompts, values, "Settings"

return if not results
@@depth = results[1] #Tried to solve the array error with this. 
#The Error goes away but the value isn't passed on.

I tried with a:
puts @@depth
but nothing is visible in the console.
Any ideas how to solve this?

@@depth = results[0]
There's only one input - so the first in the array 'results' is [0] ?
Ruby's array-element counts always start at 0, NOT 1 !
Don't ask why !!

[Pixero]

Ah, makes sense. I should have tried that. I just thought that it was like this:

results = inputbox prompts[0], values[1], "Settings"[2]

[Pixero]

Your right. It passed the value to puts at least.
But now I'm getting: Error: #<ArgumentError: comparison of Length with nil failed>

I'm trying to set an attribute of a DC from this Input box and I guess DC's don't like the .mm thing. Is there any other way of getting the correct lenght as a plain number? From tests that works but it gets translated to inches when returned so it screws up the Input box value the next time it is opened.

[TIG]

NO ! Use:
@@depth = 400.mm unless @@depth prompts = ["Depth"] values = [@@depth] results = inputbox(prompts, values, "Settings")
Then if results use:
@@depth = results[0]
??

If it's for a DC issue, then try using a float 400.0 in the inputbox and then later on pass it as a value that is converted to inches etc for the DC code ? Later on, when you recover it convert it back ?

[Pixero]

I do it exactly like that and I still get this error:

Error; #<ArgumentError; comparison of Length with nil failed>

...

Edit: Ok, I'll try that.

Skip the inputbox part for initial testing.
Simply set your @@depth to various 'types' - e.g. float, mm etc, and test each.
Which works ?
That gives you a clue as to which 'type' can be successfully passed...

[Pixero]

This works but next time the value is in inches.

@@wdepth = 400.0 unless @@depth
	
# Dialog box
prompts = ["Depth"]
values = [@@depth]
results = inputbox(prompts, values, "Settings")

return if not results
@@depth = results[0]
@@depth*=0.0393700787 

In the last line I turn the mm value into inch so it will be correct in the DC but I need to multiply that value by 2.54 to get it back to mm for the prompt the next time.
Where and how to do that?

[Pixero]

Solved it this way so I never have to pass the @@depth value to the DC.

@@depth_inch = @@depth*0.0393700787
