strings!!

[interceptor]

This is bloody annoying. My biggest annoyance with this engine is the strings!

Current dilema: How can i convert a stringc or stringw to a c8?

[loki1985]

both stringc and stringw have a c_str() method, just like regular c++ strings... read the documentation next time.

Yea, thanks for that, but .c_str() gives me the problem of

cannot convert parameter 1 from 'const wchar_t *' to 'irr::c8 *'

I did actually read the manual first but i didn't understand, that's why i posted it on the forum. Isn't that what forums are for?

its not really what you're asking, but maybe it works...

Code: Select all

core::stringw test = "test";
core::string<wchar_t> test2 = test.c_str();
core::string<char> test3 = test.c_str();

No, the forums are an answers knowledge base first, which you should query. So do the search first. Should bring up hundreds of threads which already solved this. There are basically two ways, one is correct for all encodings, one only works with the usual ANSI characters or little more.

I had the same problems, comming from a b3d, bmax, c#, php background i completely agree c/c++ string handllings a mess,
so do what i did, Create your own wrappers for strings. You can quite easily implement high level methods like Replace, Mid, Trim etc.
then you can use ".c_str" for quickly convertig it to an array.
basically keep everything as a "string" in your prog, and write your own conversion functions just once for using with irrlicht etc...

OK, if you call c_str() on a stringw, you'll get a wchar_t array out of it.

If you want a c8 array, then you'll have to convert the content of the wide string. If you're OK with the contents as ASCII/Latin-1 (rather than utf-8), then Irrlicht can do this for you, just by creating a narrow string from the wide string.

Code: Select all

	stringw wide(L"content");
	
	stringc narrow(wide);
	const c8* narrowContent = narrow.c_str();

Well, i kinda gave up on using c8's. stringw suited my needs better..
