QUESTION

Trying to add a restart keystroke to my problem but facing encounters

Asked 2021-May-02 at 07:43

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.

QUESTION

Discord.py - How would I remove a certain character from a variable?

Asked 2020-Nov-17 at 14:04

So I have a command which allows you to create a channel and a role based on what the user gives. The problem arises when the channel name is over a word. For example:

>newrealm Space Invaders (emoji) (mention)

This command will raise an error because now it's assuming "Invaders" is the emoji.

Which is why I am now using something like this:

>newrealm Space-Invaders (emoji) (mention)

Now the problem with this command is that while creating the role, the name is Space-Invaders OP. Is there a way to remove the - in the role's name?

There are several options that would solve this problem:

encase the name in quotes so the function recognizes it as one argument.
receive the name last with a special syntax:

QUESTION

Error while creating an executable installer for a python game file made using pygame module

Asked 2020-Sep-30 at 04:11

I made a game using pygame module of Python. I thought to make an executable installer of the file so that anyone could play that game without even having to install python or pygame. I used the module cx-freeze to create an executable for my game file. I stored the code for making an executable installer in file called setup.py and saved it in the same directory as of the game file and all other files which are required for the game like images, sounds, etc. When I executed the command python setup.py build to create an executable I started to get warnings and at the end this error occurred:

ANSWER

Answered 2020-Sep-29 at 15:09

I have not used cxFreeze before, so I cannot directly help with your issue, but I would really recommend using pyinstaller to package python programs. I have used it with pygame before and it has worked fine, and doesn't even require a setup file.

Pyinstaller can be installed using pip, and to package a file you call: pyinstaller file.py, along with any flags you may need. In general, I use pyinstaller file.py --onefile --noconsole, which creates a single executable file.

Pyinstaller does not package asset files, so you must supply them with the project, but all python files used by the project (including libraries) are packaged, so no code needs to be supplied with the project.

Pyinstaller can be temperamental sometimes, so I'd recommend first creating a simple hello world file, and packaging it using pyinstaller helloworld.py --onefile, and then running the file in the dist/ folder.

The docs are not always very helpful for pyinstaller, but I found that the best way to learn to package projects is slowly increase the complexity of the projects you try packaging, and check each project works after packaging.

If you use relative script and asset imports (e.g. pygame.image.load('image.png')), you'll need to move the resulting .exe to the original script's location (the .exe is normally created in the dist/ folder, which will not work if you use relative imports and run the .exe from there.

If you want to add an icon, you can use the --icon flag like this: pyinstaller file.py --icon=image.ico (the icon file must be a .ico file - you can always you online converters if need be)

I believe you are trying to do this:

c = sqrt(pow(a,2) + pow(b,2))

But your code has one pow() too many. Happens to me too, when I make I make game sounds in my head, while coding (pew pew pew)

Try to remove one pow()

from math.pow(math.pow(enemyY - bulletY,2)) to math.pow(enemyY - bulletY,2)

First of all, you are requesting an integer between 0.1 and 0.5, which is not possible for obvious reasons.

To get a float you can use random.uniform(0.1, 0.5).

Although I have to note here, that pixels can't be float values, because there are no half pixels. Thus you have to think whether you really need a float value for a pixel change value.

pygame.QUIT is not a function - it's a constant, simply an integer representing a QUIT event. You can't do if event.type == pygame.QUIT(), you need to do if event.type == pygame.QUIT, without parenthesis.

You also don't really need to call pygame.quit() and exit() at the end of the program - both pygame and the program itself will be terminated when the program reaches its end.

Apart from that your program works for me, images are showing. Make sure your image is visible over a black background and if it is and you are still having problems I'll try to help you with them.
