Irrlicht Engine

Do anyone kown how to convert from 'wchar_t' to 'const irr::c8 *'
??

i have a problem like this
\virtualmuseum\modeleventreceiver.cpp(189): error C2440: '=' : cannot convert from 'wchar_t' to 'const irr::c8 *'

THANKS~~
PLS HELP~~!

the tutorial work
why my program have link error?

i hv link irrklang library file
and it has been included, still not work

i have try IrrKlang, but when i createIrrKlangDevice
it link error:

unresolved external symbol "__declspec(dllimport) class irr::audio::ISoundEngine * __cdecl irr::audio::createIrrKlangDevice(enum irr::audio::E_SOUND_OUTPUT_DRIVER,int,char const *)" (__imp_?createIrrKlangDevice@audio@irr ...

what sound-libraries should use?
in the demo of Irr, it said that can play sound, but it still can't play
so is that need to include something?

or is there any tutor / ref to teach me how to add sound to the Irr program?

it's urgent, coz i need to add this function within these 2 weeks

thx

anyone knows?

is there any load music example?

thx~

i have try to set node->remove()

but i can't run this at the beginning of the function
if at the end, then nth is drawn

i think at the beginning it throw exception is that node is NULL
but i check if this is not NULL, then node->remove()

however, it still run not NULL
so what's suppose to do?

yup, i havn't call the drop() in the scene 2 but still can't clear the mesh/drawing when call the scene in second time

the problem that is not drop, i understand that drop means delete the device, but how can i clear the mesh when load in second time?

my confuse is that the mesh can't be clear ...

void Museum::runMuseum(int win_width, int win_height, s32 id, float x, float y, float z, bool backward, IrrlichtDevice* input_d)
{
if (false == backward)
{
Params.AntiAlias = false;
Params.Bits = 32;
Params.DriverType = video::EDT_DIRECT3D9;
Params.EventReceiver = 0;
Params.Fullscreen ...

anyone knows??

smgr->getMeshCache()->removeMesh(mesh) is just remove the mesh from the memory
but how can i remove the mesh and drawing?

how about
smgr->getMeshCache()->removeMesh(mesh)??

i have call this after the drawing process
but still no effect

then how about when i call it at first, that is calling smgr->clear() before drop()
it still crash, why??

it not like that if i have string a = "abc"

then i run a = ""
a = "def"

then a is def and assign a new value?

is that possible in device or smgr?

the flow is

device -> create

event receiver -> call sec operation(pass device)
run operation 2

while loop
{
draw things
}
device->drop

in sec operation
use device passed from the first

device->beginscene
draw thing
device->endscene

event receiver -> still using the first one (call back to ...
