Convert string to char*

Dynad · 02-04-2010 09:09 PM

Hey,

I want to convert the engine Str to char* but the compilers gives me great errors which i don't really understand. probably i don't know how to use it.

Tried operator CChar16 * and operator ()

The following code:

PHP Code:

rakpeer1->Send(message.operator CChar16 *, strlen(message.operator ())+1, HIGH_PRIORITY, RELIABLE_ORDERED, 0, UNASSIGNED_SYSTEM_ADDRESS, true); 

Gives me this error:

PHP Code:

error C3867: 'EE::Str16::operator const CChar16': function call missing argument list; use '&EE::Str16::operator const CChar16' to create a pointer to member 

Thnx,
~Dynad

What are the arguments for that Send method?

Code from my project:

Code:

wchar_t* f = (wchar_t*)file;

size_t origsize = wcslen(f) + 1;

const size_t newsize = 100;

size_t convertedChars = 0;

char nstring[newsize];

wcstombs_s(&convertedChars, nstring, origsize, f, _TRUNCATE);

converts CChar* [file] to char* [nstring].

regards,
Kevin

Str8 str=Str("text");
const char* s=str;

in shortcut:

->Send((Str8)message,

Ok but what kind of type is "file"??

U cant just cast from CChar16 * to wchar_t*.... or am i missing something?

Nvm, Esenthel ty that is working smile

For Esenthel's example: My compiler says
"EE:Str8 can't be converted to char*"

**Esenthel** · 02-04-2010 09:39 PM

yes, forgot to add 'const' (fixed it)

Perhaps some of us could get together and make a RakNet tutorial with login and chat for Esenthel Engine with client and server projects?

Perhaps similar to Player demo (which used ogre): http://princeofcode.com/blog/?p=249
(warning uses a slightly older version of raknet)

Would that be useful? I remember some other people said they were using RakNet, but can't exactly remember who.

I like the idea

Dynad · 02-05-2010 12:42 AM

ok but when i try to convert it back to a Str i get strange Chinese text. probably the cast is not correct.

I tried Str test = (CChar) (packet->data+1);

The data in the packet->data is correct debugged it smile

try CChar8* (or just char*)

Dynad · 02-05-2010 07:38 AM

(char*) works fine pfft

Ive a tiny question about the GUI, when i add a message i need to open the chat bar first with a button -> thats set on the letter T. But when i push on T it adds the letter T right away in the chat bar.

TextLine *chatbar;
I tried to use chatbar->clear(true); before chatbar->visibleActivate(true); but this is not working.

when you detect 't' char, you can try immediately calling Kb.eat(KB_T) for example, this should eat the input

Dynad · 02-05-2010 05:56 PM

uhm ok, but is the eat an engine function or...?

**Esenthel** · 02-06-2010 12:08 AM

oh, it is currently hidden
ill make it available for the next release
