addTriangleSelector() crashes the program

[reiskaG]

My first language is Finnish...

My problem is collision with MetaTriangleSelector. I'm adding triangleselector to the metatriangleselector and I compile the program. I run the program and then it stop for few seconds and then it crashes . If i take the addtriangleselector() away it works nicely.

The code:

Code: Select all

#include <irrlicht.h>
#include <iostream>
#include <windows.h>

using namespace irr;



int main()
{
	// let user select driver type

	video::E_DRIVER_TYPE driverType;

	printf("Please select the driver you want for this example:\n"\
		" (a) Direct3D 9.0c\n (b) Direct3D 8.1\n (c) OpenGL 1.5\n"\
		" (d) Software Renderer\n (e) Apfelbaum Software Renderer\n"\
		" (f) NullDevice\n (otherKey) exit\n\n");

	char i;
	std::cin >> i;

	switch(i)
	{
		case 'a': driverType = video::EDT_DIRECT3D9;break;
		case 'b': driverType = video::EDT_DIRECT3D8;break;
		case 'c': driverType = video::EDT_OPENGL;   break;
		case 'd': driverType = video::EDT_SOFTWARE; break;
		case 'e': driverType = video::EDT_SOFTWARE2;break;
		case 'f': driverType = video::EDT_NULL;     break;
		default: return 0;
	}

	// create device

	IrrlichtDevice *device =
		createDevice(driverType, core::dimension2d<s32>(640, 480), 16, false);
		
	if (device == 0)
		return 1; // could not create selected driver.
    
    
    
	video::IVideoDriver* driver = device->getVideoDriver();
	scene::ISceneManager* smgr = device->getSceneManager();

	scene::IMetaTriangleSelector* meettori = 0;
    scene::IAnimatedMesh* q3levelmesh = smgr->getMesh("koo.bsp");
	scene::ISceneNode* q3node = 0;
	scene::IAnimatedMesh* maalimesh = smgr->getMesh("dwarf.x");
	scene::ISceneNode* maali = 0;
	
	if (q3levelmesh)
		q3node = smgr->addOctTreeSceneNode(q3levelmesh->getMesh(0));


	scene::ITriangleSelector* selector = 0;
	
//LOOK THIS
	if (q3node)
	{		
		q3node->setPosition(core::vector3df(-6.719374, 26.503641, 9.631497));

		selector = smgr->createOctTreeTriangleSelector(q3levelmesh->getMesh(0), q3node, 128);
		q3node->setTriangleSelector(selector);
		meettori->addTriangleSelector(selector);
selector->drop();
	}

//....
	
	
		if (maalimesh)
		maali = smgr->addOctTreeSceneNode(maalimesh->getMesh(0));


	scene::ITriangleSelector* selector2 = 0;
	
	if (maali)
	{		
		maali->setPosition(core::vector3df(2350,200,45));

		selector2 = smgr->createOctTreeTriangleSelector(maalimesh->getMesh(0), maali, 128);
		maali->setTriangleSelector(selector2);
		selector2->drop();
	}


	scene::ICameraSceneNode* camera =

	// disable mouse cursor

	// add 3 animated faeries.

	video::SMaterial material;
	material.Texture1 = driver->getTexture("../../media/faerie2.bmp");
	material.Lighting = true;

	material.Texture1 = 0;
	material.Lighting = false;

	// Add a light

	smgr->addLightSceneNode(0, core::vector3df(-60,100,400),

		  lastFPS = fps;
		}
	}

	device->drop();
	
	return 0;
}

No comments for rest of the code, please. It's not complite yet

And the Problem:



I hope that you undestand my english and my problem.

Would be a good idea to actually initialise the metaSelector

metaSelector = smgr->createMetaTriangleSelector();
