Get access to Vaegrant's source code (+shaders) and maybe pay for my lunch? 😳 www.patreon.com/dafluffypotato Also, there’s a mistake at 4:20. I may have been talking to someone in Discord at the time and not noticed that I highlighted an unrelated section of code from a file that wasn’t even the associated shader. lol The base shader functionality is open source though: github.com/DaFluffyPotato/pygame-shaderlib

I am constantly amazed at your work... just knowing the background footage was made with pygame is amazing

I enjoy periodically coming back to your videos. Every time I see one pop up on my feed, I think, what's Da Fluffy Potato been up to in Pygame now, and im always impressed by how much content you will have released in the meantime to binge.

I would like to personally thank you for uploading your code for this. I know you have a more up to date video using modernGL, and that this code probably isn't for everyone, but honestly this code was exactly what I needed. I have an existing pygame game and was looking to add a few openGL features to it but wanted precise control over the integration of GL and was having a HELL of a time getting ANYTHING to run, and I literally was frustrated in a way I had never been before. Then I came across this video, downloaded your code, and after a little tweaking got it to run and was finally able to start playing around with and testing everything. I got a shader programmed up for my needs and I don't know if I ever would've made it this far without you. Thanks, thanks, thanks. You da man :)

I ran a test once comparing pygame's software blit vs opengl rendering a quad to draw many copies of an image to the screen with random sizes and positions. With any large number of images to draw, opengl was 1-2 orders of magnitude faster than the standard blit function even when each instance of the image was a separate vertex array. I'm using opengl for the pygame project I'm currently working, but I'm using the moderngl wrappings instead of PyOpenGL

When I switched from software surfaces to pygame._sdl2 GPU rendering my CPU usage was reduced from 7% to 0.5% or less. And this simple wrapper is far easier than the opengl wrappers, while also letting you use the directx or vulkan backend of SDL2 instead of opengl.

So I suppose it takes more work to get all the images rendered and placed correctly, but then you get much better performance and can use shaders without it running super slow?

Great video. I wasn't aware of any pygame games that use this so it's cool to know it's possible.

Since I'm Supposed To Learn C++, I Won't Learn Pygame Anymore, But You Fill Me With So Much Inspiration, Thx So Much!!!

Dude you are a big inspiration for me when it comes to learning python

I was wondering if you have a public version of the current engine you've made? Love your videos!

Hey , for your dialog system , I think if you calculate before how words will appear avoid words warped at the end line , anyways good job bro

I can feel how happy you are because of the update.

Cool style, i love this

Live your work dude

Thanks for the video. I have my own game engine written with c++/SDL2.0. With the game mostly finished, I decide that I want to use a bloom shader. I guess that what I need to do is just convert the SDL texture for main screen to opengl like you do.

I spent a few weeks in the fall of 21 trying to implement shaders in pygame for a fireworks sandbox, and I thought I reached a dead end cus I really didn’t want to rewrite the whole program to use OpenGL rendering. I was only doing this as a month long project and the time constraint meant it wasn’t worth it to switch to OpenGL. I will have to implement this bypass into my code and then I can finally make my fireworks have proper bloom in real-time!!!

Good video

just… WOW! It’s soooo amazing

Hi DafluffyPotato. Your work is wonderful no doubt about that :) I just want to ask if you have a tutorial on how to make sprite I'm really bad at drawing or even designing. If you have a suggestion on where should I start. That would be greatly appreciated. Again, thanks for the work you've done!!

How about using ModernGL? Wouldn't it be a more friendly library (Basically a pythonic wrapper for OpenGL) than raw direct PyOpenGL, which directly ports every function there is from C's OpenGL?

Blubberquark was recommending that. That's not what I did because I wasn't aware of it at the time, but that would probably be easier.

@Smelly Frog used an OpenGL texture to add Steam Overlay to his pygame game. Honestly worth checking out if you ever wanted to add it to your own games at some point.

@DaFluffyPotato

I saw that. The steam overlay only works with OpenGL, so you kind of have to do that for it to work.

This is very impressive

Could you make a video on how to convert a pygame surface to an opengl texture and render that to the opengl display? If not no problem, but I think other people might be interested into that as well perhaps. And as a side note, how did you learn all this? Through documentation or any other online sources?

Everyone I've seen do it uses the pygame.image.tostring() function (which is slow af) then glTexImage2D function and I think it may not feasible unless you have low-res graphics or create all the textures ahead of time and do all the graphics through opengl and not try to mix the two.

great video love what your doing, i have a question what does the ftexcoords stand for in 4:18 cause i try to copy the CRT tv style in my game, it will help if you told me

Theoretically, yes.

You could use this lighting thing for fire particles but it's probably super slow. It's based off your particles video, removing during iteration video, and lighting in pygame video: import pygame import sys import random from pygame.locals import * pygame.init() Clock = pygame.time.Clock() Screen = pygame.display.set_mode((800, 700)) pygame.display.set_caption("Base") particles = [] particle_colors = [(127, 63, 15), (127, 63, 31), (127, 63, 0)] click = False def glow(radius, color): glow_surf = pygame.Surface((radius * 2, radius * 2)) pygame.draw.circle(glow_surf, color, (radius, radius), radius) glow_surf.set_colorkey((0, 0, 0)) return glow_surf while True: Screen.fill((0, 0, 0)) mx, my = pygame.mouse.get_pos() if click: particles.append([[mx, my], [random.randint(3, 10) / 5, random.randint(6, 15) / 3], random.randint(6, 12), random.choice(particle_colors)]) for i, particle in sorted(enumerate(particles), reverse=True): particle[0][0] += particle[1][0] particle[0][1] -= particle[1][1] particle[0][1] += 1 particle[2] -= 0.1 if particle[2] 9: color = (255, 255, 255) elif particle[2] > 6: color = (224, 112, 61) elif particle[2] > 3: color = (112, 61, 30) else: color = (56, 23, 11) # pygame.draw.circle(Screen, color, (int(particle[0][0]), int(particle[0][1])), int(particle[2])) #will look ugly with this radius = int(particle[2]) * 2 Screen.blit(glow(radius, (particle[3])), (int(particle[0][0]), int(particle[0][1])), special_flags=BLEND_RGB_ADD) for i in range(3): copy = Screen.copy() copy.set_colorkey((0, 0, 0)) copy.set_alpha(127) Screen.blit(copy, (i * 2, i * 2)) for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() if event.type == KEYDOWN: if event.key == K_q: pygame.quit() sys.exit() if event.type == MOUSEBUTTONDOWN: if event.button == 1: click = True if event.type == MOUSEBUTTONUP: if event.button == 1: click = False pygame.display.update() Clock.tick(60)

Can u make a video about saving/loading ?

Super, awe$ome

Your game is looking incredible. So…. I’m on episode 2 of the devlog so this might not work for you… catching up. Have buffs in the game that make you really strong but are unusable. Pair those with debuffs to make it usable. I.e. +100% run speed(making you zip back and forth on the screen) and then get something that does more dmg but slows you down.

Dude, the game in the background is PyGame...? If so, I would like to ask: how to make such exact collisions? All my attempts to do at least something that we see in game engines have not been successful, it just doesn't work correctly and with terrible errors...

Is programming hard? I feel very dumb trying to learn it.

I'm suggesting to try Ebitengine. It very similar to SDL2 but with fragment shader support out of the box. Also Python is too bad for multi-platform development.

I use pygame._sdl2.video for GPU rendering without using pyopengl at all. In fact I even converted Aeroblaster to use this GPU rendering. This way I can run games at full HD resolution and work with SDL2 Textures from within pygame. I wonder if I can combine pygame._sdl2.video with shaders? I don't know why everyone ignores the experimental GPU rendering in pygame. This is the only way to get good performance on underpowered devices, such as Linux or Android retro handhelds.

I haven’t used it since it’s still sorta undocumented (at least the last time I checked). I believe you should be able to use shaders on SDL2’s textures. Not sure if that’s implemented though.
