Thank you so much it worked perfectly despite the loads mistakes I made... It had for me 4 days in a row, a few mental breakdowns and struggles, but I managed to solve everything and follow your path and I"m very thankful because I just finished my first python project with you :)! Btw I have an advice for people who watch this; create a checkpoint save and save it everytime when you ran the project without any error, so you wouldn`t have to restart the project everytime you have an error. Thanks again!

Been programming, for well over 40 years, in BASIC, various assembler languages, FORTRAN, COBOL, C, Perl, php, and several scripting thingys. After much resistance, I finally broke down and decided I should spend some time learning more about python. Watched the 4.5 hour tutorial from Mike, pygame demo of Connect 4 (part 1), and then watched this. Best use of a cold Saturday in a long time. In about 8 hours, I've a decent handle on the basics, along with graphics use. I can't thank this channel enough. I might actually learn some JavaScript now. ;)

[@mattmovesmountains1443]

About halfway through this code-along, my program would force-close as soon as I hit the shoot button. I couldn't for the life of me figure out what was different between my code and Tim's, so I made a file comparison program that printed each line of both of our codes, one line at a time. Got to the issue, fixed it, and it works! Noob for the win

[@christopherfrias183]

[@robinnutbeam750]

Hi Tim. Great tutorial, it has helped me to better understand what code in Python/ Pygame can create. I managed to add background music to this game, which I learnt from one of your other Pygame videos I had an error with the def collide (obj1, obj2): section. When I ran the program it said that the argument result expected was an int value but returned a float value. I managed to get the code running by using the int function before the offset_x and offset_y. like this: def collide(obj1, obj2): offset_x = obj2.x - obj1.x offset_y = obj2.y - obj1.y return obj1.mask.overlap(obj2.mask, (int(offset_x), int(offset_y))) != None If anyone else had the same problem I hope this helps. All other code works great :) thanks Tim

[@williamneck7897]

Thanks for being so specific explaining every single line of the code, learning python this way becomes much easier and dynamic than reading books full of theory (I'm not saying these are useless but for me learning hands on is proving to improve the learning curve and the interest in programming in a beginner level) Thanks again Tim keep it up!!

thank you so much my brother Tech With Tim i'm using this for my final project

If anyone of you are getting the "FileNotFoundError: No such file or directory" error (at around the 10min mark) then one of the reasons could be that you are not running your Python from the folder that you are working from. Meaning, many IDEs work from the root or base folder like ".../Documents/Python Scripts" and if you created a folder for this project like ".../Documents/Python Scripts/Space Invaders" then you need to change your IDE's working folder to ".../Space Invaders". Also remember to use the correct slash \ vs / , whenever you need to use it for paths etc. Also space between words of a folder name need to be handled appropriately.

At one point, when you REPLACE, in python it also replaces the file name from ship to player and then it throw an error, so I had to go back an manually replace player back to ship so it could find the right asset.

Hey man, I just want to say I appreciate the living hell out of you. How have I only just discovered you. I guess perhaps its because this is the first time I have dabbled in pygame and you came up. But good god. I have not found a better teacher for coding related topics. Seriously, you teach better than my profs do. If your someone who has never touched pygame, following along, you go over all the built in functions and what they actually do. I love that when you're using an unfamiliar library. I even downloaded Sublime text to try out. Was curious as to how you got the intelligence going and to get the parameters to pop up for the built in functions?

[@varivalentinuzzi3602]

Great lesson. I changed to just lose a life instead of game over when health comes to zero. I also want to introduce a points counter each time shoot down an enemy ship. To test my self

[@philipeby5418]

I noticed that too. I think it was just a bug he didn't catch. But great tutorial nonetheless

[@dejavukun]

Thanks a lot for your videos Tim. I had a question. How do you start with building such projects? Do you use references? Do you use other people's code initially? Like supposed you are starting out with PyGame module(I know that now you are pretty experienced with it and you can build up stuff on own), how would you approach building a game like let's say PONG. Could you explain your approach. Could you make a video on this topic? Like how we can approach things while making a project which can minimize copying stuff. One thing that I do is that if I learn something from a blog or a video, i try to understand it. Then, mostly I will make a variant of it. That way, I am practicing also and using the concepts I learnt without copying much.

[@jfsimard79]

Muito bom, estou começando no pygame e seu vídeo ajudou muito a entender melhor a iteração entre objetos.

[@thepaperbowser]

For the issue of enemy lasers shooting off center from the enemy ships, I used a different solution that doesn't involve overriding the inherited shoot method: Use an image editing program (Photoshop, Paint 3D, etc.) to edit the size of each laser image asset (red, green, and blue) to be the same width as its corresponding ship image asset (red, green, and blue). NOTE: Make sure to keep the transparent background! Thank you for the tutorial! This is really helping me learn Python and is giving me good practical practice for how to work with classes.

[@styk3000]

def shoot(self): if self.cool_down_counter == 0: laser = Laser( *self.x - ((self.laser_img.get_width() - self.ship_img.get_width()) / 2),* self.y, self.laser_img, ) self.lasers.append(laser) self.cool_down_counter = 1

Hey there,if you got any errors like: " int got float" then the error is in the instance of player and if you have tried to divide the WIDTH/HEIGHT with some values so it will spawn at the center or somewhere of your screen if so...then the problem is when you try to divide that numbers that returns a floating number so what you can do is: import decimal decimal.Decilam(Now just do your math stuffs) i faced this error and saw the entire video 3 times..but after all i found this problem..its hard to find this type of error...HOPE THIS HELPS

Hey Tim. Amazing tutorial !! I managed to make the game and I really enjoyed your way of teaching. Quick question, I am trying to make my version of the game by adding "lives" which could be an enemy ship but instead of removing 10 points of life and collide, it will add 10 points to my player. I tried a few ways by myself but without luck. My way of thinking was to define that when the enemy ship from when randomly was selected, if it is green for example to add points. I guess the error was mostly that I havent defined ship."green" anywhere. Any help or comments will be highly appreciated. Thanks again for the video

[@hossumquat]

If anyone is wondering why the Y coordinate increases going down instead of up, like it does in mathematics, I believe the reason is because that is how screen rasterization on the old CRTs were done. It would draw from the top-left corner and go to the right first, then back and down a line to draw the next row, etc. Why did that do it that way? Probably because that was the way people read books here in the west, left to right and top to bottom in the same way. So maybe that will help you remember how the coordinate systems work in graphics programming.
