CS2 Metamod Plugin std::stringstream

Hi there!

Can someone please tell me why is stringstream not working with int's inside the metamod plugin?
E.g.:

Code:

//this works

std::stringstream ss;

ss << "123";

//ss.bad() == false here

Code:

//this not works

std::stringstream ss;

ss << 123;

//ss.bad() == true here

Seems like all streams (std::cout, std::clog, std::cerr) not working with any numbers (int/double). If cout, clog, cerr is objects and engine or metamod can replace e.g. rdbuf for them so why even stringstream not working?

Re: CS2 Metamod Plugin std::stringstream

There are many c++ examples, what use also string and stringstream.

Also, try this:
Create variable int with value.
Add that in your stringstream ss <<

Not works as well.

Code:

std::stringstream ss;

int a = 777;

ss << a;

//ss.bad() == true here, ss.str() is empty

Im using s1_stub_mm example from latest mm sources and latest hl2sdk-cs2. This code was launched inside the Load function.

I would start looking <string> and format.

Forget stringstream :S

Thanks, I know about the formatting functions. But stringstream is used inside some libraries that I want to use. And they break when loading from mm.

I will try to investigate more

Re: CS2 Metamod Plugin std::stringstream

What if you do:

ss << 123 << " ";

Same. After ss << 123 stream state is bad.

Re: CS2 Metamod Plugin std::stringstream

If this has something to do iostream badbit...

What if you use:
ss.clear();

...after you declare stringstream variable?

But something is off, can't say what.
Also, what require stringstream ?

If above thing not help.
Try use string and format.
Then finally, add that string into stringstream
