Actually my question is already asked, but answers didn’t made me content.
I don’t think people at epic doing things in different ways for fun. I don’t think seasoned veterans of c++ doing things from different ways for fun. There should be a reason as to why they used uint32:1 to create a boolean. Thinking that even they use a rule to add ‘b’ to boolean variable name prefixes, it probably has a very good reason.
I would love to know that reason, thanks in advance.
Please epic staff and community share your knowledges with me
You are absolutely right - there is a logical reason behind this. uint 32 is used to create a Boolean because of bit fields and alignment. Basically, these are the tools that allow more effective memory management.

I actually know about bitfield to some degree and that article helped some.
Just to confirm, if i use uint32:1 i will just have 1 bit while i use a bool i will have 32 or 64 bits and many bits wasted. This way we are saving memory, right?
Yes, you are right. You see, a bool should be at least one byte long (due to processor limitations). However, since there are 8 bits in a byte it has enough space to keep 8 bits (or 8 bools).
Thus, if you have a data structure featuring multiple bools, you don’t have to specify a byte for each - one byte can be shared.
