Translation and rotation

[Anthony]

Have never used two smgrs yet but I think you have to do something like:

Code: Select all

driver->beginScene(true, true, video::SColor(0,100,100,100));
smgr1->drawAll();
driver->endScene();

driver->beginScene(false, false, video::SColor(0,100,100,100));
smgr2->drawAll();
driver->endScene();

It's a long shot

I think using separate scene manager may not do the job.
Using 2 scene managers means there should be 2 cameras.
So confused -,-

Code: Select all

#include <irrlicht.h>

int main() 
{ 

   IrrlichtDevice *device = 
      createDevice( video::EDT_OPENGL, dimension2d<u32>(640, 480), 16, 
         false, false, false, 0); 

   if (!device) 
      return 1; 

   device->setWindowCaption(L"Hello World! - Irrlicht Engine Demo"); 

   IVideoDriver* driver = device->getVideoDriver(); 
   ISceneManager* smgr = device->getSceneManager(); 
   IGUIEnvironment* guienv = device->getGUIEnvironment(); 

   ISceneManager* smgr2 = smgr->createNewSceneManager();

   camera2->setTarget(core::vector3df(0,0,0)); 



   while(device->run()) 
   { 
      driver->beginScene(true, true, SColor(255,100,101,140)); 
      smgr->drawAll(); 
      guienv->drawAll(); 
	  smgr2->drawAll();

   } 

   device->drop(); 

   return 0; 
}

Code: Select all

smgr2->setActiveCamera( smgr1->getActiveCamera() );

maybe this could work. Taking the active camera of the first scene and set it active to the second.

or;

Code: Select all

   ICameraSceneNode *camera=smgr->addCameraSceneNodeFPS(0, 100.0f, .3f, -1, 0, 0, false, 3.f); 
   smgr->setActiveCamera( camera );

Both actually do the same thing

[wsw1231]

Anthony,
have you run the code?

Do you know why the texture cannot be loaded in smgr2.....?

[Anthony]

nope, I don't know. But why are you adding a cube twice? Shouldn't you have the cube in smgr1 and then that pivot of the cube (I assume this is what you are trying) in smgr2 to render it over the cube.

And nope I haven't run it.

[wsw1231]

Hey!!! It seems the arrow is in front of the cube now:D
But......I still dont know why the texture cannot be loaded in smgr2 =,=

Don't know that either but do you need it? Think you are creating some sort of editor where you have pivots wich only are coloured. If so you don't need any texture in that manager.

Have seen some topic about it though, can't remember how the thread is called or in wich forum.

[wsw1231]

Code: Select all

arrowX->setMaterialFlag(video::EMF_LIGHTING, false); 

This can solve!!!

[Anthony]

yes, well it depends on how you colour the things.

If you use the S3DVertex colour that works.

If you use it with a light (diffuse, emissive or ambient...don't know) you need lighting ofcourse.

Think the first would be the fastest to use. Anyone, please correct me if I am wrong.

[wsw1231]

Now I can do this



But now, the problem for me to handle is to let the program now I am clicking on one of the arrows to perform object translation about one of the axes.

I think I need to add another collision manager for smgr2

Any suggestions?
