Im working on a space invaders type game and I have a keyboard controller class but the problem is if I want to move my player I can shoot at the same time, how can I change my controller to fix this?
ANSWERAnswered 2021-May-26 at 12:39
Do not calculate the speed, acceleration and direction in the
KeyEvent. You should do that in your GameLoop. You can memorize the keystrokes in the KeyEvent and then process them in the GameLoop.
You could query the KeyEvents as follows.
Some basic python code with the help of the pygame module. I want to be able to spawn another enemy every time my previous enemy reaches 300px on the Y axis. I tried to search for solutions online but I did not find anything helpful. I'm a complete beginner so pls excuse me if there's a pretty obvious answer to this.....

Do not load the images continuously in
enemy. Loading an image is a very time consuming operation. Load the images once at initialization.
I know this question has been asked before but I'v tried different approaches and I can't seem to be able to fix it.
I know I have to reset my important global variables in order to correctly restart the game. The reset of those variables is done when lives == 0 -> I reset the global variables, main menu becomes True and Game False which should put me back in the main menu.
However when I run my game, as soon as the lives reach 0 the code finishes and exits -> Process finished with exit code 0.
The issue must be in my while game loop but I'm unsure what I'm doing wrong. I'v also tried wrapping my game logic in a function, this seems to mess with my game since I only get the frozen state screen, no enemy spawning and not able to move.
Any ideas what might cause this issue?

You are setting game = False, but using that in the while loop. As soon as game is set to False the while loop exits and the game ends. If you want to do it this way, use another variable in the while loop:
I have this error when running the script from terminal but works from
ANSWERAnswered 2021-May-15 at 02:08
You're trying to execute the script with global python which doesn't have the pygame package installed. So, you have to activate the virtual environment first. To do this, go to venv/Scripts/ and there will be an "activate" file that you need to execute. Once you have done this you can run your script and it should work.

I suspect that pygame failed to initialize. This propogated to:
I am writing a simple invaders game. To add damage to the bases I figured I could blit a small, black surface on the base at bullet impact, and use a mask to check if the bullet was on the damage or the base, but it isn't working and I feel I am misunderstanding the mask. The first collision is detected but after that it also detects a collision but doesn't put any more damage on the base. I thought because the surface was black the base mask wouldn't include it, but it isn't working. Here is a short test to demo this. Press space (or any key) to fire a bullet at the base. I thought maybe I should generate a new mask for the base but that doesn't work. The mask collide is from the pygame sprite code on github....
ANSWERAnswered 2021-May-07 at 05:47
pygame.Surface object is changed you need to recreate the mask with
pygame.mask.from_surface. However, the mask is generated form the Surface's alpha channel. Therefore, you need to make the damaged area transparent. Create a completely transparent rectangle (RGBA = 0, 0, 0, 0) and
blit the rectangle using the special flag
BLEND_RGBA_MIN). Finally recreate the mask:
So I currently have an Enemy Class that uses sprite groups and a projectile class that does not use sprite groups.
I check the collision of my projectiles against the enemies in the sprite group. If an enemy is hit, the enemy sprite gets removed, the score is incremented and the bullet gets removed from the screen. At the moment only the enemy sprite gets removed.
ANSWERAnswered 2021-May-08 at 17:17
I can't see the drawing code so I am guessing that you are still drawing the beam. Make beams a spritegroup and do this in the loop (not in the beams class)
pygame.sprite.groupcollide(beams, speedboats, True, True)
Which will remove both from their respective groups.
So I was trying to build this game using a free course on Youtube by Freecodeacademy(feel free to check them out) and after I finished I tried to add my own restart key log to the game. In the sense that I wanted that if people press R the game restarts.
I have tried the following methods
Put the game loop in a separate function and try to use recursion to replay the function over and over again but while the game does work, the images such as the bullet image or background does not load and hence it does not work properly
I have also tried creating a new python file in the same project and tried to import the main file over and over again using importlib.reload(main) but I can't seem to do that either.
I was wondering what else could the solution be and if there is a more efficient solution. I will leave my code down below and would appreciate any help.
Ps: I am only a armature in coding right now so I understand this problem might be small and stupid but I do want to learn from my failures and mistakes. Also I apologize if there is something wrong with anything in my question. This is my first question on stack overflow....
ANSWERAnswered 2021-May-02 at 07:43
Write a function that will reset any variables that change when the game is running:
I'm trying to automate the www.freeinvaders.org version of Space Invaders using Python and Selenium. The actual game works through a HTML5 canvas element, which is wrapped in a shadow-root.
Using the answer to this question, I'm attempting to expand the shadow-root, so I can click the canvas and 'play' the game.

It seems that this is a known issue filed on bugzilla.
The geckodriver devs also say that the WebDriver spec needs to be updated. See: w3c/webdriver#350.
Following the advice to return the children of shadowroot
return arguments.shadowRoot.children it finds 4 elements:
Im creating a small retro space invaders type game and wanted to hide the turtles being spawned in the background of the program while having a "loading" screen in front. is their any way to do this? (This is the first question i've asked on here so i'm not sure what code i need to include)...
ANSWERAnswered 2021-Apr-15 at 02:40
As a rule, turtles can never appear behind anything drawn by turtles. I recommend you put up your "loading" screen message, and create your turtles invisibly:
