Camera goes straight through Quake 3 map...

[IrrGamer]

Yeah, I know you set the collision or something but the collision tut isn't helping. The map-20kdm2 is what I'm using, so I need help making the walls "solid". Also, I heard by doing this you won't be able to go up stairs...

Here's the code:

Code: Select all

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

using namespace irr;

#pragma comment(lib, "Irrlicht.lib")

int main()
{
	// ask user for driver

	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) Burning's 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_BURNINGSVIDEO;break;
		case 'f': driverType = video::EDT_NULL;     break;
		default: return 1;
	}	

	// create device and exit if creation failed

	IrrlichtDevice *device =
		createDevice(driverType, core::dimension2d<s32>(640, 480));

	if (device == 0)
		return 1; // could not create selected driver.

	video::IVideoDriver* driver = device->getVideoDriver();
	scene::ISceneManager* smgr = device->getSceneManager();

	device->getFileSystem()->addZipFileArchive("../../media/map-20kdm2.pk3");

	scene::IAnimatedMesh* mesh = smgr->getMesh("20kdm2.bsp");
	scene::ISceneNode* node = 0;
	
	if (mesh)
		node = smgr->addOctTreeSceneNode(mesh->getMesh(0), 0, -1, 128);

	/*
	Because the level was modelled not around the origin (0,0,0), we translate
	the whole level a little bit.
	*/
	if (node)
		node->setPosition(core::vector3df(-1300,-144,-1249));
	smgr->addCameraSceneNodeFPS();

	/*
	The mouse cursor needs not to be visible, so we make it invisible.
	*/

	device->getCursorControl()->setVisible(false);

	int lastFPS = -1;

	while(device->run())
	if (device->isWindowActive())
	{
		driver->beginScene(true, true, video::SColor(0,200,200,200));
		smgr->drawAll();
		driver->endScene();

		int fps = driver->getFPS();

		if (lastFPS != fps)
		{
			core::stringw str = L"Irrlicht Engine - Quake 3 Map example [";
			str += driver->getName();
			str += "] FPS:";
			str += fps;

			device->setWindowCaption(str.c_str());
			lastFPS = fps;
		}
	}

	/*
	In the end, delete the Irrlicht device.
	*/
	device->drop();
	return 0;
}

The collision tutorial helps plenty, just look through it carefully. Research a bit more before you post on the forums.

From what I see in your code:

- You have defined a basic FPS camera with no arguments. It will work, but use the defaults arguments.

- You don't have defined a triangle selector for your Occtree. This need to be specified if you want to have a collision response animator analysing something.

- There is no collision response animation defined and it's not applied to your camera. The main reason, why your going thru the walls.

In case you would need some examples to set this. look this:
http://irrlicht.sourceforge.net/phpBB2/ ... hp?t=23707

This code basicaly load a IRRscene from IRRedit, create a triangle selector for each Occtree meshes then add them in a MetaTriangle selector, then finally apply the collision response animator to the FPS camera (based on the meta selector).

For the stairs, you only have to define the proper size of the "collision sphere" on your collision response animator. If the sphere is too small, it will stop. If the sphere is bigger than the stair then it will go over it.
