I need to create loading progress.
I am select next way:
create new theard for updating window:
Code: Select all
DWORD WINAPI UpdateSplash(LPVOID data)
{
ILoadSplash* splash = (ILoadSplash*)data;
while(GetDevice()->run() && splash->Enable)
{
GetVideoDriver()->beginScene(true, true, SColor(255,200,200,230));
splash->BeginUpdate();
//splash->GetSceneManager()->drawAll();
splash->EndUpdate();
GetVideoDriver()->endScene();
}
return 0;
}
Afte creating theard a start loading function.
But theard does not updates my window
. I have a black screen.
But I am set color (200,200,230).
As possible load the resources in separate theard?

I am rewrite my code and put to enoter process loading function.
All images loaded as white rectangle
Irrlicht has problem with multithearding?

It may not be Irrlicht that is causing your problems, but Irrlicht is not thread safe. You should only be rendering from one thread. You can't really even load meshes or images from a thread because the mesh/image loaders are not thread-safe; they use shared data internally.
You are going to make your life very difficult if you start to write threaded code with Irrlicht.

Surely there is an alternative method for a game loading screen. Maybe do it in a serial fashion and stick an update command between every loading operation? And interpolate somehow inbetween...
Can anyone show me an example

HM. I am have a bug.
I am create function for update screen
Code: Select all
void ILoadScreen::RenderScreen()
{
GetVideoDriver()->beginScene(true, true, SColor(255,0,0,0));
OnBeginRenderScene();
smgr->drawAll();
OnEndRenderScene();
GetVideoDriver()->endScene();
GetDevice()->run();
}
//OnBeginRenderScene is overload for ILoadScreen::OnBeginRenderScene
void LoadLocationScreen::OnBeginRenderScene()
{
GetVideoDriver()->draw2DImage(tezx, position2di(0,0));
}
I am run function RenderScreen for update loading screen between stage of the loading.
For example:
Code: Select all
RenderScreen();
...
//load resources
...
RenderScreen();
//load resources
..
RenderScreen();
But I have bug in process!
Line
Code: Select all
GetVideoDriver()->draw2DImage(tezx, position2di(0,0));
Do not draw texture tezx, it draws texture which is loaded at current moment.
Please take me example for create normal loading.

I am rectet realize RenderScreen()?

I am replace my render function with:
Code: Select all
void ILoadScreen::RenderScreen()
{
glClearColor(0,0,0,0);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
OnBeginRenderScene();
SendMessage((HWND)GetVideoDriver()->getExposedVideoData().OpenGLWin32.HWnd, WM_PAINT, 0,0);
SwapBuffers((HDC)GetVideoDriver()->getExposedVideoData().OpenGLWin32.HDc);
}
But this bug is remained.
I am view variable tezx in debug - this value is const (for example: 1357e88)
It is system bug?
Why is not drawn image necessary for me?
P.S. I am use Visual Studio 2005
