I'm going to make Conway's Game of Life.
However, an error occurred in the process of drawing the grid.
What should I do?
(I'm Korean, and I'm using a translator.
So the sentence may not be natural.
Please excuse me.)
저는 콘웨이의 생명 게임을 만들려고 합니다.
그러나, 격자를 그리는 과정에서 오류가 생겼습니다.
제가 어떻게 해야하나요?

Maybe this will help ?
Thank you!
I didn't fix the error about drawing lines, but I knew another way to draw a grid.
Instead of drawing a line, I will use the method you told me.
@TIMAI2 Umm.....
I think it's a bug.
When I tested it on iPhone, there was no bug.
But, when i tested it on android, there was bug.
So this is a BUG OF APP INVENTOR!
I don't think it is a bug either (let's not jump to conclusions so fast). Please post your new blocks in English as well. 
no
this is bug.
no bug on that, bug there is a bug on my app.
on iPhone:
on android:
They are same project.

Ah, this is not a bug either. Your Android phone may take a while to draw the horizontal lines, so you have to use a Clock timer to give your app some time to draw the horizontal lines.
Ah, I see.
Thank you for letting me know!
No. This is a problem of the Android emulator. Should be OK on real phone.
No. I once bumped into this issue on a real phone drawing multiple grid lines all at once while helping a user. Let me try to find it.
