This typing engine will run any text you want to in one sprite with 76 blocks. Use it in your own projects by dragging the enter sprite into your backpack. In your project, all you have to change are the inputs, like the "ask" block, and the "text" input of the "enter text" custom block.
USE IT IN YOUR PROJECTS AND STUFF!!! (And I did all of the coding, but I got most of the costumes from the scratch library)
