Can I adjust a variable that reads from another variable?

JGoode — Wed, 19 Jul 2017 11:34:55 GMT

I need to edit the variable A but still be able to set it up so that when the object changes it 'A' will revert back to a set value. I can only manage to get 'A' to read from another parameter that I have made but this does not allow 'A' to be edited. Is there a way around this? In my case there are 2 variations of the objects where the width changes so I need A to reset to a default.

Sounds like you'd need a toggle switch for each of the instances.

So if you want A to define the width, that's situation 1. If you want other variables to determine A and this in turn defines the width, that's situation 2.

That way the two instances shouldn't interfere or exclude eachother.

The issue comes when I change one of the widths. Because it scales with B, when I change the width of one then change to a different variation, either the B or one of the width variables will stay the same and not scale correctly until a value is re-entered in. Here is a part of the master script

if (show_text) then
	if GLOB_MODPAR_NAME = "text_width_2" then 
		 B=text_width_2*(2/3)
	  endif 
	
	  if GLOB_MODPAR_NAME = "B" then 
		 text_width_2=B/(2/3)
	  endif 
endif

if (show_text = 0) then
	if GLOB_MODPAR_NAME = "text_width" then 
    	B=text_width/0.88 
  	endif 

  	if GLOB_MODPAR_NAME = "B" then 
     	text_width=B*0.88
  	endif 
endif

PARAMETERS A=A, B=B

if (show_text = 0) then
	A = text_width
endif

if (show_text) then
	A = text_width_2
endif

and here is a part of the 2D mul2 calculation

 if (show_text) then 
	mul2 text_width_2/0.075, B/0.05
else 
	mul2 text_width/0.0441, B/0.05
endif

Maybe split things up into callable subroutines and run them in order that is needed to keep the variables scaled as needed?
