Really cool. Probably makes sense to add the pixel grid overlay before distorting the screen shape, since the shape would affect the grid as well.

[@stephaneduhamel7706]

Shaders are often counter-intuive. In this case, if you want to have the distortion affect the grid as well as the image, it's better to do the "distortion" first. When doing the distortion, what happens is that the coordinates of each pixel are transformed to correspond to another texel on the image. You can then use these same transformed coordinates to draw the grid. And the effect would be pretty much the same (though with possibly better quality, and faster) than if we first added the grid on top of the image, and then distorted the new image in another pass.(it would use 2 shaders instead of 1)

[@lepels]

@@stephaneduhamel7706 Is there not also a chance of blurring the pixel grid? You'd of course want crisp crt lines, not them being blurred because of a distortion effect.

[@BranchBruh]

the human brain doesnt think like that. it adds more emersion to the game if you do it like this. since the goal is to make it look like a rounded tv screen your brain seeing the squares curve will actually give you the image better.

You're brilliant, man. Doing as much as you can in just code is incredible, really shows how far you can get with nothing but C++ and an iron will.

[@dandymcgee]

Hah, love it. I like how you somehow made this a tutorial withing droning on for hours about each line of code. Straightforward, beautiful and to the point. I'm not a big fan of bloom in games; I feel like every single person I've seen use bloom applies like 700% too much and it just washes out the whole scene, but after you applied the pixel grid it toned it down a bit so it didn't look as bad. The end result was quite impressive. Thanks for sharing.

[@PezzzasWork]

Yes it's easy to over use bloom :D in this case I indeed forced it a bit because of the crt shader which tends to mitigate the effect

[@GMPranav]

The game looks so neat! I would like to see an option to disable the chain labels though, they just cover the beautiful particle effects.

[@supereligo]

I love the way you have implemented the modern touches. I especially like how dynamic feeling you have made the game with the springs.

[@iamdozerq]

Springs and physics alone make a lot of fun already, all other things just multiply it. Great work, dude!

It looks so good that I want to download and play it!

I'm very happy that I discovered your channel a year ago. You inspired me so much by your videos that I learned C++ and SFML library which helped me understand a lot of things that I didn't know about physics and maths by making different programms/games. and now, I'm making my own engine :D

[@krccmsitp2884]

This looks sooo great!

[@dandymcgee]

A tiny bit of torque spring on the player ship could feel nice. But it's totally not necessary. Too many springs makes everything feel too loose, and it's nice to have a few things be very crisp and stand out as special. It also helps avoid confusion about where the player's hitbox is.

[@yemyint9725]

[@icemojo]

Amazing work. Is there any chance the game is going to be available as a tutorial series? Anytime someone searches for C++ game programming with either SDL or SFML, they're either 10 years old, or the final result game is boring as heck. We need more high quality C++ tutorials which produces high quality end products. Please!

No gravity in space! The debris should just travel in whatever direction it was already going till it collides with something or exits the screen.

[@Bingo901]

[@charetjc]

I've never understood how one would relocate colors to another pixel with shaders. Impressive result overall.

[@amosnimos]

cool

[@nicholaslaux]

What are the memory/storage requirements of the compiled code in the final version? I'm curious if this could have, in theory, been made back when c++ was released, if you could take the coffee from all of the libraries back with you, or if any level of modern hardware is required for any of the physics/graphics requirements?

[@RomanSteiner_xD]

Shaders require a GPU with shader support. I think the first "T&L" hardware came out in the 90s, like 10 years after c++

[@mmankt]

can you make a tutorial where you show how to get the same versions of SFML and compiler, and how to install it?

[@chriswinslow]

[@rukna3775]

how did u break the things? and how did u make ur custom enemy movement patterns?

[@thehambone1454]

Next gen space invaders! How cool! How did you approach breaking apart the squares? Just broken into a lot of triangles?

[@tissuepaper9962]

My guess is: 1. Pick a certain number of random points inside the square to be the vertices where different cracks intersect. 2. Calculate the dual of the Voronoi diagram for those points 3. Each connected region in that diagram is instantiated as a physics object, and the original square is deleted. Alternatively, if you don't care about making sure that the debris can be reassembled into the original image, you could just manually make a couple of different particles out of parts of the spaceship sprite, and randomly spawn them at the same moment that you delete the original ship and render the smoke.

[@multiarray2320]

@@tissuepaper9962 this sounds like a lot of work for this small effect.

[@tissuepaper9962]

@@multiarray2320 the point of the "hard way" is to make the debris look more realistic. One should be able to take the debris and reassemble it into the original sprite, and every sprite shouldn't break apart exactly the same way. It really isn't that much extra work, and you could precalculate a few different options to make it faster at runtime.

[@jacobpeifer2875]

My only suggestion would be that the debris from the destroyed aliens should either explode outwards in all directions, or the player's ship should be a tank with the ground beneath it. It doesn't make sense for everything to be subjected to a such a significant gravitational force if they're fighting in space. Unless the player is defending an absolutely gigantic space station, or the battle is taking place in the earth's upper atmosphere? Which in either case should be represented graphically.

[@PezzzasWork]

SFML is a good start since it will allow you to get your hands dirty on more and more complex projects until you create your own game :)

[@CristiNeagu]

2:44 So... what happens if an alien is identified as, say, the right hand blue limit (3:16) and then the last left hand orange block is destroyed? Will the blue block bounce off of the left hand wall if there is no orange block?

[@VestigialHead]

When the orange block is destroyed the code will look for the next leftmost alien which in this instance will be the same as the rightmost alien. So that alien will now be the orange and the blue.

Too many clones... imagine if the popular games arriving at the right time were different from space invaders, tetris, mario, super breakout, etc. How crazy would it be if a strategy had been popular lol. I guess everyone was playing cards and chess for that. ( "strategy games existed though". And they were the most popular games at the time that get talked about and cloned the most to this day? )

That’s very impressive. I would love to know how you did all that.
