How to once to declare and initialize variable for many GDL elements

Anonymous — Mon, 27 May 2019 08:32:16 GMT

I need to declare and initialize array.
dim my_array[]
my_array[1]="1"
my_array[2]="2"
Count of the my_array items can be changed in time to development aims.
And need to use it in any my GDL elements of the library.
How I can declare andi initialize this array once for all my elements?
Help me please(.

I have never tried it on multiple objects.
Maybe the LP_XMLConverter can do this - I have never used it but I believe it can reset variables in multiple elements.
I may be mistaken though - as i say i have never used it.

Otherwise you will need to do it individually in each object.
I have done this in an object I made so I can easily reset all the array values back to default while I am testing or changing the object.

Create a boolean parameter called "reset_defaults_swch"
Then add this to the master script (it may work in the parameter script as well, but for some reason I have it in the master script"

if reset_defaults_swch = 1 then
	dim my_array[]
	my_array[1]="1"
	my_array[2]="2"
	
	parameters my_array = my_array

	reset_defaults_swch = 0
	parameters reset_defaults_swch = reset_defaults_swch
endif

Now just turn on the boolean parameter in the parameter list - it will turn back of instantly but will have reset your array.

You could do it without the boolean switch but you would have to manually uncomment/comment the lines otherwise it will always be initialising.

Probably LibraryGlobal is a key - can be changed by MVO and then injected to the calling object.

I was going to mention Library Globals and MVO but I ended up deleting it.
That will work for resetting values in placed instances of the objects but not the object default (script) values themselves.

Ok, I missed the "main" part.
So there is another way but the XML tool:
- make an object with desired parameters and values
- set it as a template
- apply the template to the desired objects...
(delete the template when necessary ... when deleted it will be allowed to change the template without deleting the previously inserted parameters)
