Space Invaders project
I’m making a game similar to Space Invaders. Is there a way to check for an event like shooting less frequently? Right now, if you press space bar fast enough the top shot will disappear before it hits the top of the screen. I was wondering if you could check for the shot event like 2/(how long it takes to get the the top).

Another method is to fire shot only if you have less than 2 shot on screen.

A few tips: Your first blit is pointless. Since you already start bliting in the while loop.
You could store ship_left and ship_top in a tuple, so there will be less clutter in your code.
Use functions, and give them meaningful names, this way it will be easier for you and others that read your code.
Back to your question. This is how it is normally solved in games like these.
You make a list of missiles. Each KEYDOWN event would create a new missile, and append it to the list. If let’s say there are 10 missiles in the list, the missile is not created.
It best to create a separate class Missile. For each object in the list, you should do the following:

Space invaders is originally an arcade game released in 1978. It is a 2D shooter, the first of its genre. The goal, as for most of the arcade game of this time, is to obtain the highest score by destroying continuously the incoming aliens.
Here is two gifs of gameplay :
Many aliens are invading world and move slowly to you, shooting laser randomly in your direction.
The spaceship (aka the player) can move on the horizontal axis, avoiding laser shots. The spaceship can also fire at aliens, but it should aim properly since it’s only one shot at a time. It can take cover below barriers, but they are gradually destroyed by enemy lasers and spaceship missiles.
Hit aliens are destroyed and award points. Periodicaly, a mistery saucer will appear, granting a lot of bonus point if destroyed.
Download the source code and type :
python : >= 3.7.6
pygame : >= 1.9
This game was implemented to reproduce as faithfully as possible the original arcade game.
Sounds have been edited but the original material comes from :
Gameplay inspiration comes from youtube :
There is a configuration file config.py which contains all the configuration data. It can be modified to customize the game experience.
I’m very glad you take some time to look at my game and at my code!

Space Invaders is a two-dimensional fixed shooter game in which the player controls a ship with lasers by moving it horizontally across the bottom of the screen and firing at descending aliens. The aim is to defeat five rows of ten aliens that move horizontally back and forth across the screen as they advance towards the bottom of the screen. The player defeats an alien, and earns points, by shooting it with the laser cannon. As more aliens are defeated, the aliens’ movement and the game’s music both speed up.
The aliens attempt to destroy the ship by firing at it while they approach the bottom of the screen. If they reach the bottom, the alien invasion is successful and the game ends. A special «mystery ship» will occasionally move across the top of the screen and award bonus points if destroyed. The ship is partially protected by several stationary defense bunkers that are gradually destroyed by projectiles from the aliens and player.
If you have the correct version of Python and Pygame installed, you can run the program in the command prompt / terminal.
Note: If you’re using Python 3, replace the command «python» with «python3»

Thanks for checking out my game and I hope you enjoy it! Feel free to contact me.

Inspired by Space Invaders, Alien Invasion is an arcade game where the user has to use a ship to destroy all the aliens in the screen to reach the next level. As the levels increase, the aliens and the ship’s bullets both move faster, the user has to steer the ship dexterously to create a new high score. The game ends when either the aliens collide with the ship or they reach the bottom of the screen.
Testing my new abilities with python I decide to make the space invaders, with the help of the book, Python crash course by Eric Matthes. In this Project I learned how to detect mouse movements, display information in textual and nontextual ways, how to use python libraries, how to use nested loops to create a grid of elements, how to track the statistics in a game and use flags to determine when the game is over.
Since this game is created using Pygame modules. You will need to install Pygame and its dependencies.
On Linux: Install the dependencies first using the packet manager.
If you want to add sounds to the game, install the following libraries as well:
Then finally install Pygame using pip:
On OSX: Install the dependencies using Homebrew.
And for sound libraries:
Ending by installing Pygame using pip:
On Windows
No installation is needed! To play the game, run the alien_invasion.py file using Python3 and enjoy!
###2. The game images aren’t loading properly on my OSX. What do I do? This is the OSX’s SDL image glitch I was talking about. You probably have a relatively newer version of SDL. This is what is making the images load incorrectly. You can solve this problem by degrading the SDL version down to 1.2.10. There are several ways to do this, I found this method the best. Run this on your Terminal:

This is my second game, not yet finished but working. I’ve put so much time into it I wanted to get feedback before continuing. I always learn so much from those that comment.
Whilst my first (still a work in progress), is object orientated, this isn’t. Given that though, I certainly appreciate the OO method more now.
Please try the game out and post your feedback:

Just a minor improvements.
1) If you count something manually or repeat exact lines one after other probably you do something wrong. Use iteration if possible
2) Try not to use \ to split logical line. You don’t need it anyway if splitting inside (). Also I’m not familiar with PyGame, so I can guess what the parameters are but not always:
3) # create user events and # event timers looks a bit painful. You should try to use dictionaries more often for creating special options and then just iterate over them.
But that requires replacing many variables like this:
Also note that I try to sort functions and variables in alphabetic order if possible.
4) Multiple if statements are bad, since they all will be processed one after another every time code is executed. Use elif or better: dictionaries. Again:
Edit:
If you don’t want to introduce classes you should probably stick with elif statements. You can try to modify global variables, but very carefully since they can mess code logic easily and usually this a bad practice to use many global variables:
On the other hand with classes you can edit class parameters anywhere in the code as well as obtain parameter values:
