We are both iOS. I am confused on how it works on one but not the other.
Are you both testing the same copied code? Did you create your code and your friend created his?
We have the same code. I started it but then had to go so I sent it to him about half way done and he finished it and sent the finished product to me and I am using that.
We have the same code but his global top left works but my global top left does not work.
show your relevant blocks and error message screenshot
It works on an old android phone that I have so I think that it is the phone that is causing the problems.
i had a problem where the tetris blocks move slightly further from the canvas. like 2 blocks are hidden beneath the canvas when going down and also left and right.
and when i try to stack them up, this error appears. the tetris blocks also seems to collide with each other as well. what do you think might be the problem?
Since the turorial have many functions into seperate procedures.
you need find our which procedure cause this error.

this is my code. can you please check the block code? i rechecked my code with the tutorial multiple times but i found no error. everything i followed is the same. can you help check it because i believe you are more expert in this and i may mislooked any error.
thankyou for replying, so what can i do to fix that?
compare this with the tutorial to find out the problem.
ohhhh i see, my mistake 
. thankyou so much for fixing it, i appreciate it so much! thankyou!
Thanks for sharing the aia file so I just need to move the break block right under the set block to fix the app. 
is there any way to make it using an image instead of color? Im a bit of a beginner myself, so I'm not sure if it's possible or not
you can following this tutorial first to understand how it works. then you can change it to imagesprite version.
the link doesn't work for me?
It's working from my side.

這是沒修改的
我想请问一下 App Inventor开发探底--俄罗斯方块开发笔记金从军 第15章 完善游戏功能 · 俄罗斯方块开发笔记网址里说得绘製预报组块怎麽编程,还是版本更新以前的设计已经不能了,虽然前面十章都还可以,预报组块显示不出图片我不太懂怎麽修改通过对画块过程的调用
你说的跟我这个不是一个教程啊。如果你会开发前面14章的功能，这个应该不难。不过是在一个新的画布上划线而已。
