Imagine calling something "meh" because what a single person did isn't more impressive than Unity, a program that has been developing for almost twenty years by hundreds of employees.

@Blobfish_Times 7 месяцев назад

As someone who has done speedruns of crystal seeker, its really cool that the game was designed with speedrunning in mind. I was actually the first person to "discover" the axe climbing at 17:00, so it was crazy to see it was intended all along. It was really fun to run the game, I should really go back to it sometime, maybe try to get the Any% record

The person who said this is not impressive doesn't know what they are talking about. This "generic platformer" is better than anything I could make in my 2 years of using unity because like you said it has a soul. In my opinion you have something truly special here. Hats off to you 👑

@OhCrapI_He 6 месяцев назад

It was designed for speedrunning, and there's a lot of movement tech utilizing knockback to get you through faster. It ain’t much compared to, say, SM65 or Crash Bandicoot, but not only are those some of the best of the best (especially at the time), but they were made on platforms designed for 3D stuff, while this was made on Scratch

@BoiGamer124 6 месяцев назад

Yeah I don't know what the hell that guy from the beginning's problem is. It is INFINITELY more impressive if you somehow make a 3D game in an engine meant for 2D games, rather than obviously using a 3D game engine (Unity for example) to make a 3D game

Update: not only did he just make a physics engine, but he also made a 3D LEVEL using it (don't forget it is a 2D game) literally called "WHAT". He also made a programming language inside Geometry Dash (Spwn), and hosted the biggest collaboration to make a level (around 14.000 participants) called "Place" that worked like the r/place subreddit. Just search it, it's amazing.

"Z buffering vs Painter's algorithm." I was working awhile back on something 3D and this was really a problem. I ended up going down a huge rabbithole trying to figure out how to correctly segment triangles analytically.

@ggenije 7 месяцев назад

there is also method called BSP, which is same painter's algorithm but it splits triangles that way you never have errors, at it doesn't have to sort triangles , make it much faster , with condition that triangles aren't moving (like in doom game). But it's EXTREMELY hard to make.

To be honest you DO expect someone with a thick accent :P seriously though, I'm actually learning about 3D objects, 3D rendering, game physics, game optimisation, ON A SCRATCH VIDEO. And I'm just halfway through. Dear god, good job!! Your power levels are comparable to that one guy who made a 3D level on Geometry Dash, if not greater!

I don't know if you think there's anything new worth discussing from it, but i would love to hear the ins and outs of how you made that game work. Going through its code has really inspired me and made me start considering transitioning my game from clones to pen rendering, but I still think I lack a fundamental understanding of how a pen-game like that is put together.

There's still a lot to be said for vectoid because vectoid have much better game design, and it isn't slow even on vanilla Scratch(expect if there are many turrets and enemies at once).
