Feel free to use this in your projects by dragging the "Scorekeeper" sprite into your backpack. You can use it by using the custom block "Render (Number) at X: () and Y: ()" Simply type the number you want to display, along with the X and Y position of the first digit of that number. The example uses the ABS value of the mouse X position, but you can use any number you want.
If you want to know how this works, press "See Inside" and read the notes in the blocks. Press the arrow on them if you want to read more. If you still don't understand it, ask and I'll try to help!
