Irrlicht data types

Irrlicht data types are so handy. I can't imagine programming c++ without them.

s = singed, u = unsigned, d = double, f float and c = char. Then add byte amount.

I wonder if other libraries include them. In fact, I wonder if irrlicht can submit these data types to IEEE to get them into a future iteration of a c++ standard.

I wouldn't be surprised if they're in boost libraries or simliar.

that's not the same thing

i think I'll get bored of writing

uint32_t
instead of
u32.

I used to include <irrTypes.h> in all my programs. Also in programs that don't uses irrlicht.

also the float

f32 is usefull. is hard mistyping it.

while when you write"float"

sometimes happens that you write "falot" "flaot" ecc.

Guys? Get a decent IDE that corrects typos like "flaot" for you...
Or one with a good auto completion so you only have to type "fl"

Well, since the using namespace directive is evil, it would be

Code: Select all

irr::u32

So typing uint32_t would probably be faster.

I have my own collection of headers with typedefs and math functions and what not I use throughout a lot of my personal projects, mostly based upon irrlicht's

It's really nice to have a set of libraries of your own which you can keep independent of the project you're doing

I use the irrlicht types in my projects too, even on iOS where I dont use irrlicht; the types are extremely handy and I've become accustomed to using them everywhere

But writing using irr::u32; would save typing the long run. Though I simply just use namespace irr; in all my headers anyway. The "probably not" is simply a coding suggestion.

While I've always hated namespaces (PHP; et tu?) they do make things nice and quantified when dealing with multiple c++ libraries. The is one aspect where C++ is really starting to show its age.

Python not surprisingly does it perfectly by treating directories like namespaces. The from x import y is fantastic.

I've sometimes just kept irrlicht included in my console programs for the handy data types. Makes the .exe bigger and has to have the .dll, but makes my job easier I think.

That's like carrying a car door while wandering in the desert so you can open the window to get some fresh air.

Seriously, the 'handy' datatypes are already there. All you need is to include stdint.h. If you want u32 rather than uint32_t, use a typedef. There is no point in including Irrlicht.

Sounds like a good idea to me!

But seriously, I'm not talking about just data types, I also like the vector classes, matrices, etc. If I only wanted the data types, I'd use a typedef. Sorry if my last post was misleading.

Wouldn't it be easier to just include irrTypes.h, or does that also require to build lib?

Haha, I was thinking this.

Just remove the namespace and you've got a perfect header.

Well, I have a blank console project that includes irrlicht by default. Why would I download a new library, learn how to use it, or recompile irrlicht, when I don't have to? It's easier not to change anything. I mean if I actually planned on releasing it, I'd of course pick something more compact. But I never release it (I use it as practice), so there's no real point in changing anything. Thanks for the concern though
