I know this comment is a year old but this video was great help and solved the issue i was dealing with for hours. Thank youuu!

thanks a lot <3

thank you so much

This is what I am looking for but it’s not connected to any key press events like player movement would be, I will keep hunting though. Lot of GREAT material by the way, you really don’t get as many likes as you deserve ❤

where'd you learn to code? did you go to school? this has that... rigorous training, feel, to it. it's seriously some of the nicest, most professional code, I've ever seen. granted I don't get around much... I'm still a newb. but this code feels like.... industrial strength! people say when they're teaching in tutorials, they give that excuse of... well this is just to show you a concept... but then everything else they write, looks the same way. no polish. if they don't teach the right way... then people don't learn the right way. then you get a buncha idiots, sitting in high places, thinkin they know what they know what their doing, because all they've ever known, is the wrong way, of something. wow that was a tangent, and a half...

Hello Maggie ❤

Very awesome video. One area where I've used mod a lot in various areas is when trying to find some angle offset. I used to work for a test and evaluation command so I would place sensors off the line of fire. Before I learned about transforms I could calulate the distance and position of a sensor using standard geometry. So if I wanted to know the x and y position of a sensor, using the local coordinate system, it would be something like X_desired = distance * (cosine(90-line of fire) mod 360))+X_current, Y_desired = distance * (sine(90-line of fire) mod 360))+Y_current.

I just noticed an error in the code in the video that I wanted to point out -- I'll fix the code in github. In the namespace example, the roll_die function takes a parameter num_sides, and then doesn't use it! The random call within the function should be random.randint(1, num_sides). Ugh!!!

Good morning Maggie ❤

Thanks Maggy, another well-run lesson! It would have great to see the final demonstration on screen. It is necessary to clear the buffer if and only if you read a string after having read a type number seems to me to summarize the matter simply.

Hello Maggie, here is another version of the loop based on your example: int i = 0; while (text.length() > i) { if (text.charAt(i) == ',') { i++; } else if (text.charAt(i) == ' ') { System.out.println(); } else { System.out.print(text.charAt(i)); } i++; } Thanks for teaching us how to think and not just applying recipes. Keep on making these wondeful videos.

I hope this helps. # Why 'while True' Loops Are Bad Practice and How to Replace Them """ [1] Understanding 'while True' Loops: - A 'while True' loop is an infinite loop that continues to execute until explicitly broken. - It's often used when the exit condition is complex or unpredictable. - Even Though it is simple, this structure can lead to a code that's hard to read and maintain. [2] Problems with 'while True' Loops: - Readability : It's not immediately clear what condition will end the loop. - Maintainability: The exit condition is often buried within the loop body. - Error-prone : Easy to create infinite loops if the break condition is missed. - Performance : In some cases, it can be less efficient than alternatives. [3] Alternatives to 'while True' Loops: a) Using a condition in the while statement. b) Using a validation function to encapsulate the loop condition. ==> Better for multiple inputs [4] Best Practices for while Loops: - Make the loop condition clear and explicit. - Keep the loop body as simple as possible. - Use meaningful variable names that explain the purpose of the loop. - Consider using functions to encapsulate complex logic. [5] When to Use 'while True' Loops: - In rare cases where an infinite loop is actually desired (e.g., in some game loops or server programs). - When the exit condition is truly unpredictable and can only be determined within the loop body. - Even in these cases, consider if there's a clearer way to express the logic. [6] The `assert` statement: - The `assert` statement is often used to catch programming errors or unexpected conditions. - If the condition inside the assert evaluates to False, it raises an AssertionError. - It helps in debugging by ensuring that the input validation logic is working correctly. - If you are confident the input will always be valid, you can remove the assert statement. [7] Notes for Studying: - It is better to only loop if the input is incorrect. - When validating user input, it's better to start with a priming read (initial input). - Use functions like (`valid_input`, `valid_password`, `correct_guess`, etc.) to validate input. - Functions improve code reusability and can be tested separately. """ # Example 1: Basic input validation loop # a. Using a while True loop (not recommended) while True: # 1. Start a `while True` loop. input_value = int(input("Please enter a number between 1 and 10: ")) # 2. Ask for input. if 1 <= input_value <= 10: # 3. `if good_input`: break # ===> break print(f"You entered: {input_value}") # b. Without using a `while True` loop. input_value = int(input("Enter a number between 1 and 10: ")) # 1. Ask for input. while (input_value < 1) or (input_value > 10): # 2. start a `While bad_input` loop. print("The number must be between 1 and 10!") # ===> A warning message. (optional) input_value = int(input("Enter a number between 1 and 10: ")) # ===> Ask again. print(f"You entered: {input_value}") # c. Better approach: Using a validation function. def valid_input(value): # 1. Write an input validation function. return (1 <= value) and (value <= 10) # <== return the good input. input_value = int(input("Please enter a number between 1 and 10: ")) # 2. Ask for input. while not valid_input(input_value): # 3. Start a `while not valid_input` loop. print("That number must be between 1 and 10!") # ==> A warning message. (optional) input_value = int(input("Please enter a number between 1 and 10: ")) # ==> Ask again. print(f"You entered: {input_value}") # NOTE: We only enter the loop if that user-input is wrong or not valid.

Thank you so much. You forgot to leave the video link 7:07 though..

Thank you Madam Magnificent 🤗great resource 😎

Thank you so much

thanks :D... J saun(a). lol. that was very cool! thanks for the shoutout! look forward to the next.

DesignCodeDebugRepeat, cool video keep it up dude

Happy holiday weekend Maggie ❤

ty it helps

Thank you, this helped me programme a grenade throwable system for my game!

Great tutorial! Didn't know this was a feature. Any tips on how to do this with two rects instead of images?

have you done one, about saving a character to file? with json? it's hard to find good explanatory videos. about how to do that, and maintain cohesion and coupling.

Nice! thanks!

Hi there, Maggie the magnificent 🎉

very nice end to the chapter. Nicely explained.. Stars were too time-consuming to fill, so I just filled with car headlights and cleared the screen after the screen filled.

Thank you so much, you 100% nailed it. So equipment should blited as parallel list while masking would be better suited for equipment color customization. Thanks for clearing that up! Presenting the concepts in contrast really helped to see the distinction between bliting the pixels we see as equipment, no different than anything else we are able to visualize on the screen, and masking where we track pixels with specific collision or in this case appearance conditions. You are an amazing instructor!!!

nicely explained. As soon as the image appeared on screen, I was like: ah yes!

Hello Professor, Is there a video in your channel of programs demonstrating polymorphic behavior? I am reading about polymorphism and I am sure that one of your videos would be a great tool in helping me understand this concept!

Thanks, this was helpful.

Hi, I have a mask question. Can masks be used for player cosmetic choices and if they can, would this remove the processing burden associated with masks if the mask was not responsible for detecting collisions at all?

first day starting python. was stuck in this.. thanks.. it was helpful

Thank you for sharing your knowledge, Professor! This video was very helpful when reviewing the concepts of Inheritance and Polymorphism in Java. I used it in addition to reading chapter 10 in the book “STARTING OUT WITH JAVA, from Control Structures through Data Structures” (by Tony Gaddis and Godfrey Muganda)!

Thankyou for this video. This helped me a lot to run java program in eclipse. I was facing the same issue.

Excellent as always. The last example with printf is a nice trick. Is it possible to post at least 2 lessons per week ? Maybe it could help the yt algorithm :) Have a nice day 💛

Wonderful videos!! I'm re-learning a lot of concepts, so thank you so much! However, here is where I need to pay careful attention and understand how looping mechanisms work properly, as I burnt out and gave up last time when I couldn't understand nested loops. Some may call it the definition of insanity, repeating something and expecting a different result (no pun intended of course 🤣).

thanks

Very helpful! Thank you so much!!

thankyou kind teacher for teaching out the conctp of pygame.vector2 , nowhere in the internet had i found that the vector2 uses top left of pygame.screen as 0 , 0(i could not read through all the documentation for this ) thankyou for explaining it in detail using animations ♥

Thank you so much! It is exactly what I’m looking to achieve in my backgammon game 👍 Great keyboard noises btw! Very ASMR ✌️

I have been watching all of your pygame videos ❤ No other content creators annotate their variables, can you explain why this is done?

This was a very awesome video and idea, thank you for creating and sharing.

wish I could like this as many times as ive used it haha

Nice breakdown, thank you. This felt a lot more like learning how to think than the bargain barrel monkey see monkey do follow along tutorial.

OMFG thank you so much i was struggling to get my sprite rotating and no of the other videos i watched were this helpfull 🙏SÓ AGRADECE🙏

That was very helpful! Thank you!

thanks

thanks for sharing your knowledge, just in this moment i'm learning java

Very nice, I am allready a fan.

the most overpowered module in the whole world is pygame.math module. now I can finally make the enemies move towards the player in my game. thank you for making this video.
