Help with School Project – Three Exercises in One AIA File

MIT App Inventor Help
1

Hello,

My name is Mohammad, and I am working on a school project using MIT App Inventor.
This project contains three exercises in one AIA file, as per my instructor’s instructions:

  1. Simple Drawing – The user draws points and lines on the Canvas.
  2. Runaway Ball Game – The Ball moves when flung and bounces on the Canvas edges.
  3. Character Control – An ImageSprite moves with the user's finger on the Canvas.

Some parts are not working correctly, especially the Ball movement in Exercise 2. I believe some blocks or settings might be incorrect, and I would appreciate any help in fixing them.

I have attached the **assignment and AIA file for review.
Could you please check the project and help me fix it?

Thank you for your time and support!

Best regards,
Mohammad

Dear @mohammadtv86m2803602 ,

I've opened your .aia file, corrected the errors (you've duplicated any event, which is wrong, please see the blocks' image below for its amendment), compiled and run it but, as I can see, it has nothing to do with your homework. .

I suggest you to search the forum for topics similar to yours (tag like "drawing", "sprites" and so on) before any attempt to make a complete app. Please also take a look to the component reference page, to learn how to use them:

Hi @TIMAI2 ,
I've seen that while I was answering him, you've already done a complete app !!! :grin: :grin: :grin:
That's why you have thousands of solutions in your "palmares" :rofl: :rofl: :rofl:

All the best, Ugo.
