Physics Demo

Hi!!

My name's Bruno and I'm new here!
I've grown-up with a NES clone and having the opportunity to write code for it, is a dream come true! I haven't been this excited about programming in years!!!

So, I've been using the 8bitworkshop IDE for a few weeks now and after creating a mini text adventure, I decided to start experimenting with collision detection.
The entire thing is written in C and I am well aware of its performance issues. Nevertheless, I'm looking forward into learning how to speed-up the critical parts using assembly (inline or files).


Sped-up footage, it's actually pretty slow...

About me:
As a professional, I'm a software developer (Python, C and some C++) for one of the big Japanese IT companies, nothing game related though, just boring business stuff.
As a hobbyist, I develop under the name "Ninja Dynamics" and I have some unfinished/work-in-progress stuff for PC and Android.
As a gamer, I'm completely addicted to Dragon Ball FighterZ (Demon~SS3 rank). I've tried to summarize my favorite games but there are just too many to mention. (Doom 2016 <3)
As an anime fan, Dragon Ball and Neon Genesis Evangelion are my favorite animes ever, alongside with Full Metal Alchemist: Brotherhood and Food Wars, just to name a few.

I have so many questions for you guys, so I'm really looking forward into learning a lot more from you all!

That's a pretty fun and impressive physics simulation!

Welcome here!

Cool. Are you handling rotation, or just bouncing? Either is neat I'm just curious.

Thank you!!


Thanks!! There is no rotation, just some basic bouncing.

What I'm trying to achieve is a high-level C game framework, while retaining an acceptable level of performance.
The collision detection module so far, was the hardest one to put together (no floats? no sin()? cos()? atan2()? ARGH!!!! ), but I'm happy I did it!

Now I'm wondering if I can rewrite it in assembly...

Nice demo, thanks for sharing!
If it would be used for a game, then a ball-ball collision detection would be handy.
Nevertheless, it's fun as is already...
