Bor Engine | devLog #000

I want to keep track of my progress in my latest quest: creating my own game engine!

It will be built on top of openGL using C++.

I’ll leave it open source but mostly uncommented, keep that in mind if you want to check out the code: it will be messy!

Why “Bor Engine” you say?
Mainly because I was bored and wanted to create a 3D engine…soooo “Bor3D Engine”? ikr
I’ll think later about a fitting acronym…

[edit]
Almost forgot: link to the code, hosted on GitHub

Bitwise Operations and Bitfields in C++

Basics of Logic:

0 && 0 == 0
0 && 1 == 0
1 && 1 == 1
0 || 0 == 0
0 || 1 == 1
1 || 1 == 1
!0 == 1
!1 == 0

Bitwise operations:

1 & 0 == 0
1 | 0 == 1

unsigned char data = 0;
unsigned char flag = 4;
unsigned char flag2 = 8;
data = 00000000
flag = 00000100
flag2 = 00001000

data = data | flag;
data = 00000100

data = data | flag2;
data = 00001100

00001100
&
00000100
--------
00000100 // now we know that flag is set into data

data = ~data;
data = 11110011
