Text Typewriter View

Hello guys, I am here with a simple but useful extension


It shows text as a typing effect in an arrangement



com.TypeWriter.aix (10.9 KB)

I will add font bold, italic and custom .ttf options

It is showing a story as a demo

Thanks to @kangris and @Sneha_Sharma for their help


Which view components does it accept? Arrangement, Label, Textbox ?

Arrangements :slightly_smiling_face:

If someone bans on making an app with a few blocks, then yes. For me it does not matter if a function takes 1 or 20 blocks.
But the fact is, if someone has a problem with coding in ai2, it might help.

You are right but this extension may be helpful for the new users or who are beginners or do not want to code the blocks

If they do not want to code the blocks they shouldn't start using App Inventor :wink:


Also it is benefitial for large scale project :relaxed: :grin:

Sorry to make this comment but - have you ever used a typewriter? The paper should start at the bottom of the screen and feed upwards for each new line of text.

See my website for a block code snippet download:
