Dude, I am studying Python and I found your channel... it's amazing!!! I'm in love with your videos and with the way you teach. I am from Brazil and I wish we could have videos like yours. So I decided to start a channel about python and pygame! Maybe I'm gonna do it tomorrow haha but I am very excited to share it with people (in English, sharing your videos for my friends and in Brazilian Portuguese making my own videos). Thank you so much and keep doing a great job!

[@Seio0987]

Great guide, as always. I changed a small thing that bugged me about the live-system. First, I created a new Function for self.live_x_start_pos: def update_lives(self): self.live_x_start_pos = screen_width - (self.live_surf.get_size()[0] * (self.lives - 1) + (10 * self.lives)) For this function, I changed the 2 for (self.lives - 1) and the 20 for (10 * self.lives). Now I called this function in the place of the original line as well as in the player collision, right after reducing the lives per one. Reason being that 1st: now the positioning looks way better with more then two Extra-lives and 2nd: if you lose a live, you'll now lose the left-most icon instead of the right-most icon.

I have a question about the alien_position_checker(). I want to point out that I do not expect you as the creator of the video to answer my question. If you do, very cool, but no expectations here. You do such great work and I am very grateful for it, thanks. 🙂 Maybe someone else is also able to answer it. at 1:02:00 why do you create a new list named all_aliens in which you put the sprites with the sprites() method. I just looped through self.aliens itself like this: def alien_position_checker(self): for alien in self.aliens: if alien.rect.right >= screen_width: self.alien_direction = -abs(self.alien_direction) elif alien.rect.left

[@Erdbeerbowle]

Hello, I'm following along, and I'm having some trouble with the self.image.fill('white') code at the 21:21 mark. When I run the code, I get a "TypeError: invalid color argument" statement, and the program crashes. When I delete the self.image.fill('white') code however, it runs fine, with the exception that I now have a "black" laser. Do you know what I'm doing wrong? Thanks!!

[@johnwall6585]

Some great techniques here, I always get confused with game programming - but find other programming ok

[@HappyLicker]

Love this channel :D

[@CodePhiles]

that was really brilliant, I enjoyed watching the tutorial till the end, hope to work on levels and adding more laser shoots at once for the player...and what are the challenges that we could face if we wanted to user higher resolutions graphic??

[@jamesbondisamonkey]

I think you can get the right x offset for the obstacle creation, each of those blocks has a string of size 10, maximum of 60 because you set each one to 6... So then you can offset it by 30 and I think that it puts it then directly in the middle

[@charg1nmalaz0r51]

yeah what i did was take the position of the last obstacle and and added its width which i got from its (row count * size) then took this from the screen width to get the space on the right then divided that by two to get the start x obstacle_x_offsets = [num * (self.SCREEN_WIDTH/amount) for num in range(amount)] end_x = obstacle_x_offsets[len(obstacle_x_offsets)-1] start_x = (self.SCREEN_WIDTH - (end_x + (Obstacle.width * size))) / 2

[@potatocat6855]

The best , keep it up

[@jamesbondisamonkey]

same thing with the alien offset. You can do (width of the screen - (alien size + space_in_betweeen_each_alien) * number of columns of aliens))/2... and that should number can be the buffer you use to start positioning the x coordinates of the aliens, which will even out the space on the left and right of screen, if you care...

[@charg1nmalaz0r51]

dont suppose you have a better solution for moving the aliens and switching directions. I found his code breaks if you slow the aliens down because more than one hits the wall and if you arent fast enough to swap directions it goes haywire. I found it out by replicating the clastic alien movement and realised how lucky his stats were to switch direction before it breaks lol. in my head a better solution is to have each alien know its position relative to the edge and switch when it reaches that offset and have the aliens move themselves. but my maths skills are shite

[@gabizehE]

I couldn't done the code of this game, because everytime I import Player and set his position, as player_sprite = Player((300,300)), pygame tells me that I've used 2 posicional arguments instead of 1 , considering that a error. What should I do? Oh! I almost forgot that I have a Windows 7 computer and my python version is Python 3.7.0. This information must be important somehow.

[@Pogomeister]

I am still at the beginning of the tutorial. The exercise about constraining the player to the window at 11:30 I solved differently. I did not create a constrain function. Instead I modified get_input like this: if keys[pygame.K_RIGHT] and self.rect.right < self.max_x_constraint: self.rect.x += self.speed elif keys[pygame.K_LEFT] and self.rect.left > 0: self.rect.x -= self.speed This also worked at that stage of the game. Is it also a good solution to stick with? Or will there be some issues later on which makes it better to use the constrain function? If the constraint function is not used for anything else later on, the version above should be better just because it is less code, right? I hopefully will get an answer to my question by just continuing the tutorial. But for the case that it will not get answered automically during the video I wanted to post the question already. :-)

[@charg1nmalaz0r51]

Theres always multiple ways to do something, just do what you feel is best for your sanity and if problems crop up later modify it, otherwise you are good to go

[@dennys.1880]

Where can i add a starting screen in the code ? And how should i do it?

[@fnxbcn369]

Big thanks!

[@DeltaNrOne]

There is 1 thing very small nitpicky thing in the very last part of the video and i am not even sure if it is better or not. When adding the sound for the laser for the player instead of loading the sound in again. would it not be better to pass the sound along to the player? I know that disk operations can be quite slow and passing it along is as fast as your game can run. for sure it wont have any performance issues with just one file in simple game like this but if you do this over and over again it might get heavy? great video learned a lot. and gonna give it some of my own features!

[@gametimewitharyan6665]

It will be very helpful if you can offer a multiplayer version of any game that you made with server and client because the multiplayer side of it is pretty hard for beginners to grasp these hard topics, and if you will teach them I am 100% Sure that everything will be crystal clear

You use the word "and" an awful lot and do not hide your accent. Also, you use words native speakers would not use in a presentation (e.g., center vs. middle). But thanks a lot for an easy-to-follow tutorial. I have learned a lot and will start developing a game for my son based on it. Greetings from a Canadian

[@Astrogator1]

what is wrong with his use of 'and' and why should he hide his accent. I am native level English speaker but still have an accent, I have spent many hours talking to people in English and some have mentioned my accent but no one has ever raised an issue with it with me. The people who do say anything have been positive. I am not sure why you needed t o raise this ? Greetings from Spain

Other than that I got everything Thanks Again For Such an Awesome Video For Free !

[@ClearCode]

Hey, I will talk about this more in detail next week (probably) in a tutorial about an overworld. Essentially, here is what you want to do: You keep the game class as it is (maybe rename it) and put it inside of another class, and that class will manage the state. That way you can switch them fairly easily.
