Listening to preference changes and applying them on another activity in android studio

Asked 2022-Apr-16 at 15:48

I have a google maps fragment in my MainActivity and a SettingsActivity that has a ListPreference option to select styles for the map. What I want to do is to listen to the changes in that preference, and change the map on the MainActivity accordingly. I can only change it on onMapReady which is a one time thing it is not a listener. How can I do this? I tried to do it in the SettingsActivity but I can't access mapStyle.

MainActivity:

Maybe not best solution, but i think you could update your map style on activity resume. After opening settings activity and selecting style you could return to map activity. OnResume function would be called and you would check which style has been selected and update map based on this information.

Maybe something like so would be sufficient:

Could you collect the items with onEach instead of collectLatest? It would solve your problem probably.

QUESTION

Can you import a pygame script without opening a pygame window (until you want to?)

Asked 2022-Jan-19 at 01:21

So, I have a game called run.py that I made with pygame, and for the most part, it works fine. And I'm trying to make a launcher for all of my pygames. But when I import it, it immediately opens a blank window. What I want to happen is nothing, until I call run.main()

...

ANSWER

Answered 2022-Jan-19 at 01:21

Yes. First off pygame doesn't initialize a game window until you call pygame.display.set_mode((width, height)).

So you can either move all your game logic inside of run.py into a function say for example...

QUESTION

When I make a new screen in pygame, you have to repeatedly click the exit button to close the window

Asked 2022-Jan-18 at 21:44

In my pygame game, when the player dies, I run a game_over() function, which displays a screen with "GAME OVER Press E to exit or R to restart." But while this is running, if you try to close the window, you have to click multiple times, and same goes for clicking E. Even if you click R and restart, you have to do this, but not before game_over() has run.

Here is game_over():

here, (and with 'e') You set 'running' to true, which breaks that loop. the following line pygame.QUIT. Does nothing pygame.QUIT is a variable, not a function, you probably mean pygame.quit().

Deny movement in pygame when player would collide with a wall

Asked 2022-Jan-09 at 19:46

I've been having trouble with collisions in pygame. Specifically, I have a player and a list of walls, and if they collide, I'm supposed to prevent any more movement in that direction.

I've tried many guides but I can't seem to get this to work myself.

ANSWER

Answered 2022-Jan-09 at 19:46

Create the objects once before the application loop. You don't need the variables playerX and playerY at all. Use player.rect.x and player.rect.y instead.

Store the position of the player before moving it. If a collision is detected, restore player position:

Weird diagrams using chains within tikz

Asked 2022-Jan-03 at 16:23

I am trying to replicate some diagrams that I made using Microsoft Visio, using the tikz package in LaTeX. The basic diagrams are relatively easy to build, but when it comes to add more than two nodes next to each other, it gets quite tricky... I can't seem to find any documentation that justifies my needs to center and align the nodes like I've done in Visio.

These are the MS Visio diagrams:

You could change the number of capture groups from 5 to the 2 that you need in the replacement. Instead of using .+, you can either use .*? or use a negated character class to match any char except a commen [^,]+

If the surrounding parenthesis of the example data should not be part of the replacement, you can use:

It's not a flaw in your code. That 1x1 image is probably a placeholder that gets replaced later by Javascript on the page. BeautifulSoup doesn't execute Javascript. If you really need that, you'll need to use something like Selenium to run a Chrome instance. It's more trouble, so make sure you need that cover art.
