Welcome to the Magical String Joiner! The String Joiner is a simple and easy-to-use custom block that can be used to join together certain letters of strings with user-inputted parameters. For example, Joining letters 1-4 of "Scratch" = "Scra" Joining letters 5-11 of "01100011010101" = "0011010"
The pen text engine used in the project is by @TheMachinumps https://scratch.mit.edu/projects/86541174/ I would've used mine but it doesn't support lowercase letters. =P You'll probably see this implemented in many of my future projects. To use the block, just drag it into your backpack!
