Debugging in Pygame

How to access information in order to debug games. The major problem we have to overcome is that the game loop produces too much output if we use the if statement. This video goes through how to create a debug panel to access information, which makes debugging drastically easier.

Apriciate it! It is really hard to keep making new topics on pygame, especially tutorials! Great job!

[@MustafaTuncay..]

Hello, I am really happy that you are preparing these tutorials, so thank you. Can you also show us how to make inventory systems in pygame? Or you already planned?

[@rudomir-__-2929]

Thanks, it's way better than print debugging, and here is the source code (i changed names a bit and add offset of '10' by default): import pygame pygame.init() font = pygame.font.Font(None, 30) def logd(info, y=0, x=0): surface = pygame.display.get_surface() text = font.render(str(info), True, 'white') rect = text.get_rect(topleft=(x + 10, y + 10)) pygame.draw.rect(surface, 'Black', rect) surface.blit(text, rect)

good job! This is what i needed for my code

If u want to make it a little bit more advanced, maybe u can put it in a class so it can keep track of the debug texts, and can auto adjust the nex text pos. Maybe a bit over complicating, but it can be helpful is some situation. But anyway it is a nice one, and i should start using something like this instead of print :D So far did not had that much problem debuging with print. Most bugs come from my stupidity such as refering to a list when i recreate the list instead of use its own clear method, and then wondering why my projectile is still keep moving after it collided with an enemy. :D This one made me headache. But could find it out when i print out the list memory adress and could see 2 different function using 2 different adress.

good topic

[@jk-gn2fu]

Could you please do a tutorial about simple shaders? Such as: simple 2d lighting (day and night, torches), outline, water effect, glow effect. I really need these tutorial.

[@mohiuddinsyed1684]

It would be really good if you introduced type hints in the debugging file. It would help us what exactly it takes and does, or returns.

Generally, on a Black background, the colour that is most legible (for most people) is Yellow.

[@dennys.1880]

Hey i always have a problem where everything i write past exit() comes as code is unreachable and i have tried everything and i cant fix it. Do you have any idea why. It might be a simple code like the one from 1:18 but still it doesn't work .

[@ClearCode]

I think you are messing up the indentations.

[@dennys.1880]

@@ClearCode i did it and still no. anyway thanks

Thank you

Yess!!! Kivy!!!

You are too amazing!

Please make a tutorial on endless runner 2d game in Godot

[@Derpy999]

interesting concept!

the moment i pressed the like button under this video was when you showed the cute pixel cat

[@seed5743]

What app do you use to code ?

[@affezippel7214]

it's a bit offtopic, but I just noticed when trying to implement this debug function in my code. Does anybody know why I get the error "TypeError: invalid color argument" when passing colors in as string ? screen.fill((0,0,0) works, but screen.fill('black') doesn't (so does every other color of the colordict in pygame documentation when I pass it as a string)

[@ClearCode]

might be because of an outdated pygame version

[@affezippel7214]

@@ClearCode I thought I'm on the latest version... better to check. upgraded from 2.0.0dev6 to 2.0.1 and it works now. Thanks!

[@MrTega1975]

Debug package for sublime text is not useful?

[@bishnuprasadpahari3780]

why aren't new videos comming

[@chigstardan7285]

Pls start kivy for ios/Android since it runs pygame under the hood.

[@SkyFly19853]

By Cython as well. That makes it very fast. Even IronPython...
