Love2D | Shader Tutorial 1 | Introduction

[@lonochka9634]

I LÖVE shaders! Thank you so much!

[@lonochka9634]

Actually, I have a gap by shaders, thanks for the tutorial.

[@tomekosika9584]

very cool! shaders were confusing to me but this is simply explained!

[@JoeyMerryfield]

this helped me a lot especially when you described what vect4 means.

[@Krunklehorn]

Informative and straight to the point, thanks !

[@BinaryMaestro1]

even though it's old. It helped me a lot

[@Domarius64]

Ah! Please continue this tutorial! Really hanging out for the next episode.

[@thomaslacourt]

this is so useful it should be part of love2d doc

[@dill__pickles]

Awesome! Thanks so much. Are you going to make more of these? it would be very much appreciated.

[@ghoom]

int x = "Hello" is technically valid cuz strings are basically pointers which in turn are special ints.

[@andresan2010]

Amazing video man! Just getting into love2d and your content is really cool!

[@marcuswilliamjohansson7624]

Very nice! You might want to slow down the pace a bit though - the topics fly by so quickly that it becomes a bit hard for someone new at shaders (like me) to follow along (:

[@merncat75]

You could hit *pause* on the video or *slow down the playback speed* to .5 😉

Anyone knows what distribution is used here? I like the simple terminal included in the desktop and the text style taskbar.

[@gustavo9758]

What graphical env are you using? looks cool (guessing it's Linux) Is it just a window manager?

[@variegatus4674]

How could I make a fade out shader for an atmosphere? GLSL has been confusing to me too, but I understand how to do it on a basic level from what you've told me. I need to figure out the shader for an atmosphere since I'm working on a space game and would like the atmosphere to look good.

[@BorneKiwi]

Great tutorial! I never really understood shaders until now :)

[@freshofftheufo]

Glsl is a lot of fun, and very cool to see it alongside Lua!

[@fryt2744]

Excuse me for asking maybe a stupid question, but why do we have {...} array after effect(...) and space between vec4 and effect, vec4 and pixel, is it like a metadata that changes vec4 to effect which draws the shader, because i didn't understood that moment

[@SkyVaultGames]

Good question! so glsl is a different language than lua, so the syntax and semantics will be different, the vec4 before effect says that the effect function returns a vec4, this is the return type. The {...} is the function body, in lua the function starts after the ')' and ends with an 'end', in glsl the functions start with '{' and end with '}'. Hope that helps

[@fryt2744]

@@SkyVaultGames thanks, i see it's C language.

[@jeremyskeleton6749]

cool was looking for shader tutorial !

[@eliaswenner7847]

I don't understand why you didn't sent a table with x and y as keys but then called it with screen.x and screen.y, I thought it would raise an error, could you please explain why you did so ? PS : I hope you will upload the next video soon 😊

[@reaper5002]

Yea I was thinking the same thing.

[@JULIUSCOOLX]

🎉🎉🎉🎉🎉

[@sph2120]

Hello, thanks for this nice tutorial. One question though, is it possible to use vec2(love_ScreenSize) to normalize the screen coords instead of using the extern instruction ?

[@nikyde9154]

Amazing video! By the way, may I ask what OS are you using?

[@SkyVaultGames]

Kah Cuun Low Glad you liked It! I'm on Manjaro linux using the i3gaps window manager

[@picalines]

Thanks, very helpful!

[@notiashvili]

Great stuff, keep it up :^)

[@flamendless]

Awesome!

[@unlisting7782]

this is so helpful thanks

[@masonhawver3577]

Can't believe i can play with shaders without whipping out glfw or lwjgl

[@skaruts]

I'm in love with love 2D, but I'm not really digging lua... :(
