Hey everyone! If you are looking to build out this game further, check out this video: kzfaq.info/get/bejne/bZlhf9KSv6m5mqM.html In it we refactor our code to use classes, fix the glitch where you can move off the screen, and add images to the enemy blocks falling down :).

In year 1991 I was 10 years old and I programmed my first shooter game with spaceships and crafts using "Basic" programming language on 8-bit computer including some puzzle games, also hacked few other games. Unfortunately my parents were keep saying that the computers will bring me nothing in my life and they will never support me. That was the reality in a soviet republic. Our childhood was ruined by fake preceptions of what we should become in life and what they were telling us at school. At the end of the days that turned me into rebellion, punk, electronic musician and I missed how this technology was developed it time, but I was really into the games and computer programming. Growed up with illigally imported Atari ( that game was forbidden in our country) present from my auntie since I was at the kindergarten. I'm sure that there is kids at same situation still somewhere...

To make the enemies move smoother, you could: ... screen.fill(BG_COLOR) if enemy_pos[1] >= 0 and enemy_pos[1] < HEIGHT: enemy_pos[1] += 1 ... clock.tick(100*SPEED) This would make enemies fall down smoother, improving gameplay. :)

Hey, Keith, I was wondering if you could change the color of the player rectangle along the progress at the game, like when you have 10 score its change the color of the player to green. I hope you could help me. btw very good video I learned a lot from it.

@KeithGalli 5 жыл бұрын

Glad you enjoyed video! :) So you can definitely do that. You should define a variable called playercolor that is initialized in the same way the other colors are. Instead of drawing the player as RED, you substitute in the playercolor we defined. Now as the score increases in the game you can add conditional statements to change the value of playercolor. So for example if you defined playercolor = (255,0,0) initially, you could add an if statement like if score == 10: playercolor = (0,255,0). The printing of the player will use whatever playercolor was most recently set to. Hope this helps!

After watching your more recent videos, I hope life is treating you kindly.

Great tutorial once again Keith! I got an idea of adding a "shoot" function, so the player can fire and eliminate enemy blocks to get points instead of dodging them. Is that a doable project for a beginner? Or do I need deeper skills than your tutorial series here to pull that off?

@KeithGalli 4 жыл бұрын

You definitely can do it! It's just a matter of translating it into programming logic. Basically you can think of bullets very similar to the falling blocks (but in reverse) . You can leverage the collision function to see when bullets collide with specific blocks and then pop that block off of your enemy_list. It might not be easy to do at first, but challenging yourself is the best way to learn! :)

I designed the background color so that it changes color slowly in the range of the whole color wheel :> Had some difficulties and after everything was solved i decided to change the color changing speed from 9 to 2 but realized it wouldn't work since I had some numbers there that needed to be % 9 = 0 so i used the random.random() function to make it so that the color changing function goes through only 50% of the time. that way i didn't need to touch the code in order to change it's speed. Big brain.

@Lyttii_ 4 жыл бұрын

@@jaydenaldum7419 yeah it's probably not that good since I had been coding for only a month at that time but it worked I guess... looking back I think these were the parts that I did: 1. in the beginning of the code where the constants were: RED = (255, 0, 0) BLUE = (0, 0, 255) YELLOW = (255, 255, 0) BACKGROUND_COLOR = (0, 0, 0) R = [255, 154] G = [154, 255] B = [154, 255] 2. under the "while not game over" part: R, G, B = background_color(R, G, B) rgb = (R[0], G[0], B[0]) screen.fill(rgb) 3. and the function was like this: def background_color(R, G, B): if random.random() < 0.5: if B[0] < 253 and R[0] != 154 and G[0] != 255: B[0] += 3 elif B[0] > 156 and R[0] == 154 and G[0] == 255: B[0] -= 3 elif R[0] > 156 and G[0] != 255 and B[0] != 156: R[0] -= 3 elif R[0] < 253 and G[0] == 255 and B[0] == 156: R[0] += 3 elif G[0] < 253 and R[0] != 253 and B[0] != 156: G[0] += 3 elif G[0] > 156 and R[0] == 253 and B[0] == 156: G[0] -= 3 elif R[0] == 156 and G[0] == 253 and B[0] == 253: R = [154, 255] G = [255, 154] B = [255, 154] else: R = [255, 154] G = [154, 255] B = [154, 255] return R, G, B (if you look at how the values of R, G and B change in the color wheel from the site, you can get an idea of what the code means. I think you can control the changing speed from "if random.random() < 0.5:" by changing the 0.5 to 0.1 you can make it 5 times slower I think.)

Hello Keith, how would you edit this code so that the player continuously moves in the left or right direction while the left/right arrow key is pressed down?

@KeithGalli 5 жыл бұрын

So in addition to the KEYDOWN event, there is also a KEYUP event. Basically you'll want to add some logic that says move left/right after you press keydown. That movement will continue until that same key is lifted up, triggering the KEYUP event. On the keyup event you'll want to stop the player motion. Does this help?

@KeithGalli 5 жыл бұрын

So I think when I originally defined SPEED I didn't have plans for it to change, and then when I added set level, I didn't think too much about how I defined it. So you are correct, SPEED is not a constant and should not have been declared with all caps. Great question.

Thanks. I always learn something new watching your videos. My problem is I want to go from beginner to advanced immediately. I've decided to watch all of your videos even if I covered the same material on a different channel.

dude, you are the bomb diggity. i gave up after about 45 minutes but learned a whole bunch about python and pygame. I really am not in the mood to spend 3 hours going over an error because I lost sleep, so now i'll just move on, but thanks. (Now i know how to do collision!)

Great video, thanks a lot. What was a surprise for me, was that when we made an enemy_list and called the intake? enemy_pos, I didn't know that in for-loops we have to use that. In the beginning, I just used 'for enemy in enemy_list ' and then spent some time wondering why it's not working. I compared our codes, and it took me a while, but I figured it out. :)) Its a great tutorial and learned a lot, Thanks!

Hello, I found this guide fun to explore. Thanks for giving us such content. P.S. at the collision function, it would be much easier to just use "if abs (p_x - e_x) < player_size and abs (p_y - e_y) < player_size"

Make sure you include the line that resets the player position after you update x (player_pos = [x, y])

KEITH you deserve NOBEL PRIZE OF MAKING PYTHON FRIENDLY TO SENIORS like me. Last sunday I spent four hours learning about lists, watching at your video and practising and making new solutions of your explanations. I am really grateful, pal, best wishes from Guatemala, I will try to record something and send you the link of video. I am old programming stuff, and sought after Python but never was so interested, because some of the folks are kind of .... less didactic.

I have, at last, a good way to organize my learning curve at Python, I have also started with the turtle, and I expect to dive deep into your lessons, in the next near months, or years, who knows. For the time being, I will share my advance with local students, who do not speak English (sigh). Dad payed me an English course when I was 15, my daughter is becoming an English teacher at the university, so English is the key to handle this kind of learning. Your voice is clear and understandable, thanks again. I will have a nice lunch on your honor, lol.
