View not updating after Update runs

[cronyakatsuki]

Hello, I'm having an issue while trying to make a simple conway's game of life where after running the update logic, the view doesn't redraw.

I did some simple checks whether or not the logic works and it does, but the view doesn't want to redraw.

Link to the repo is here: cgol

Would also like to ask how I could make it after getting the view to update on space, to update every second automatically instead.

This looks cool!

View actually is being called after pressing space, so there's likely still be an issue in your logic. To demonstrate I added a counter that shows the current step in the game which redraws after pressing space. Also, note that you weren't returning the new model after so I fixed that as well.

Here's the diff:

To update every second have a look at tea.Tick.

Thank You! I didn't return the new model correctly so view didn't update with it. Still new to go, so still have some python habits.

Also fixed up the logic a bit to actually work on correct grid/buffer.
