How to make a memory game app inventor 2

[Zerlwars]

Could you tell me how to make the correct blocks 

 Thank you

Hi Zerlwars

I'm sorry but your request is far too broad. You need to be much more specific about what your App will do, what the GUI looks like etc. 

If you haven't done so already, plan your app carefully on paper! 

Write your own blocks: Small section - proof test - next small section etc, each as a separate self-contained mini-project. If your small section of code fails your tests, open a forum post showing the blocks and explaining what you expected to happen.

Look at the examples in the MIT Gallery.   One of the Projects may do what you want and you can download the aia file.

I did some rework on the .aia you posted on an earlier thread,

and got the game mechanic to work,

reusing Screen4 (20 buttons) for smaller button counts by hiding buttons,

and reducing the number of buttons used according to the

level started.

I could not find the image and sound you wanted for timeout,

so I left that out.

Also, your background images are very large, so they slow down screen startup

and occasionally cause crashes.

I ran some of them through the site Tinypng.com to shrink them,

to ease the memory problem,

and removed a big sound file.

You use separate screens for applause to mark successful completion,

and this continues to be a problem.

(I have no good experience with multiple Screens, and prefer instead

to use multiple Vertical Arrangements in the same screen, showing only one at a time.)

Each of the 3 puzzle sizes was tested and works,

with the required delay between exposing a match and judging it.

Hi, I have imported and downloaded this app and it works on its own, however, when I try to use the same code as part of a bigger app, the screen keeps shutting down after giving me the error notification:

property getter was expecting a com.google.appinventor.components.runtime.Button component but got a YailList instead.

Why is this happening?

Thank you
