Notecard Configuration Reader by Maddox Deluxe

This new update has been tested and works great

Read the script comments to have better understanding of the codes. [v1.6 Video]

Fixes in v1.6

• Backdrop uuid now checks for NULL KEY
• Checks the notecard for saved data
• Clean up the script

Fixes in v1.5

• New uuid Key checking function

Fixes in v1.4

• Themes list format adding

Fixes in v1.3

• Empty notecard data error checking
• Spaces error checking
• Add few more comments to some codes

Fixes in v1.2

• Key names error checking
• Other fixes that are not listed

Useful Functions - (See main script comments)

• DumpListFind(list db, string name)
• integer IsElement(list db, string search)
• integer KeyNameCheck(list db, string search)
• integer isKey(key uuid)

First make a notecard called (Category Theme).Fantasy and copy the data of this one into it. The 00000000-0000-0000-0000-000000000000 just means no floor drop, but holds the key format still for error checking. The notecard format can not have line spaces and need to be done just how you see the notecard settings here, the error checking works great for the script.

// our test notecard
[Author Name] = Maddox Deluxe
// Theme [1]
[Menu Button Name] = Fantasy Tiger
[BackDrop Texture UUID] = 8f304cf2-7120-24e2-d1f1-db6b31bd6f6c
[FloorDrop Texture UUID] = 00000000-0000-0000-0000-000000000000
// Theme [2]
[Menu Button Name] = Fantasy Car
[BackDrop Texture UUID] = 517b2288-67ca-b14c-1de2-c5f5fdf5291f
[FloorDrop Texture UUID] = 00000000-0000-0000-0000-000000000000
// Theme [3]
[Menu Button Name] = Fantasy Tree
[BackDrop Texture UUID] = f6321118-cc24-6230-78a5-a257a3e33378
[FloorDrop Texture UUID] = 00000000-0000-0000-0000-000000000000
