UI Scripting; Managing access to arrays

[Aurasphere]

I would like to use arrays for certain fields; is there a way to have the UI allow a drop down from an array field rather than what Im getting atm

Manual states 

I need a drop down for each array item and dont want this behaviour which jump s the user to an standard array input and not highlighting the relative index

I would like each field to display the field value

What happens if you use ui_listfield?

How are you structuring the parameter's array currently?  Do you have 24 separate parameters each with an array, or a single parameter with 24 items in the array.

If its a single parameter with 24 items to represent each component, you can just include the array index after the parameter name in UI_INFIELD .

ui_infield param[1]  x, y, width, height

However, to get the dropdown list of available items you need to use a index-string pair value set.

So instead of setting your parameter you are storing the information in to a String, set it to an Integer.

And then use the following Value code in your Parameter script:

dim aComponentsIndex[]
dim aComponentsDescription[]

aComponentsIndex[1] = 1 
aComponentsDescription[1] = "1 - PIERS"
aComponentsIndex[2] = 2
aComponentsDescription[2] = "2 - FOOTINGS"

VALUES{2} "param", aComponentsIndex, aComponentsDescription

 And an associated example in the Interface Script:

UI_INFIELD{3} param[1], 10,10,300,20
UI_INFIELD{3} param[2], 10,10,300,20
UI_INFIELD{3} param[3], 10,10,300,20
UI_INFIELD{3} param[4], 10,10,300,20
....

However that doesn't seem to be showing the the description in the UI field for some reason, so I had to go down the route of using the UI_INFIELD dropdown method.  Full script:

!! MASTER SCRIPT
dim aComponentsIndex[]				! Create the array to story the indexes of your dropdown list
dim aComponentsDescription[]		! Create another array for Description of each item in your dropdown list
dim aComponentsImages[]				! And a last array to link to an image file for each item - this isnt required but the UI_INFIELD was requiring something

aComponentsIndex[1] = 1 
aComponentsDescription[1] = "1 - PIERS"
aComponentsImages[1] = ""

aComponentsIndex[2] = 2
aComponentsDescription[2] = "2 - FOOTINGS"
aComponentsImages[2] = ""

!! create the additional items in your dropdown in the above format




!! PARAMETER SCRIPT
VALUES{2} "param", aComponentsIndex, aComponentsDescription



!! INTERFACE SCRIPT

row_height = 20  	! Set the Height of each input row

for i=1 to 5  		! Loop through each item in the parameters array to display an input

	UI_INFIELD{3} param[i], 10, 10+row_height*i, 300, 20 ,							! parameter, x,y,width,height
					8, "",															! method:dropdown, picture_name: n/a
					0, 																! images_numer:n/a
					0, 0, 0,														! rows_number:n/a, cell_x:n/a, cell_y:n/a,
					0, 0,															! image_x:n/a, image_y:n/a,
					aComponentsImages, aComponentsDescription, aComponentsIndex		! the arrays containing the images, description and index of the dropdown list


next i

Frustratingly whenever I tried to use "" in place of aComponentsImages it was only giving a warning, but then wasnt working, so i had to create a separate array to story the blank strings for the image component of the UI_INFIELD dropdown.  

Anyone else know how to avoid that?
