Changes in version 1.5 (... 2008)
- Basic support for joystick input events on OSX tested with xbox 360 wireless controller using driver http://tattiebogle.net/index.php/ProjectRoot/Xbox360Controller/OsxDriver and a logictech wired controller
- ISceneNode::setParent and addChild now updates node SceneManager pointers if the node was from another SceneManager.
- Basic support for joystick input events on Windows, Linux and SDL devices.
- Major API change: RTTs are now created via addRenderTargetTexture instead of createRenderTargetTexture, which allows to retrieve them from the texture cache, but also changes the way of removing the RTTs, and especially one must not drop the pointer anymore.
- WindowsCE-Bugfix
- isBetweenPoints return true now even for the begin and end points, i.e. line segments are now including their start and end.
- Fix XML reader creation for non-existing files and invalid callbacks.

Changes in version 1.4.2 (22.9.2008)
- Unified the handling of zwrite enable with transparent materials on all hw accelerated drivers. This means that all transparent materials will now disable ZWrite, ignoring the material flag.
There is a scene manager attribute, though, which will revert this behavior to the usual SMaterial driven way. Simply call
SceneManager->getParameters()->setAttribute(scene::ALLOW_ZWRITE_ON_TRANSPARENT, true) and set the SMaterial flag as desired.
- Some changes for texture matrices in q3 shaders.
- Added BlindSide's irrAllocator patch for proper TextureMatrix release under Win32 with any CRT library.
- Added VC9 project files.

Changes for Version 1.4.2
-------------------------
This is once more a bugfix release of the 1.4 branch, and hence pretty API-consistent and backward compatible. The major reason to publish this release is the OpenGL bug, which made several OpenGL 2.x drivers run in SW emulation.
However, we also introduced some driver consistency fixes, which might affect your application's behavior. So read through the next points thoroughly.
SceneParameters.h (and general video driver behavior)
The way Irrlicht handles zbuffer writing with transparent materials has changed. This was an issue ever since, because the default behavior in Irrlicht is to disable writing to the z-buffer for all really transparent, i.e. blending materials. This avoids problems with intersecting faces, but can also break renderings. And this is now consistent for both OpenGL and Direct3D.
If transparent materials should use the SMaterial flag for ZWriteEnable just as other material types use the newly introduced attribute scene::ALLOW_ZWRITE_ON_TRANSPARENT like this:
SceneManager->getParameters()->setAttribute(scene::ALLOW_ZWRITE_ON_TRANSPARENT, true);
All transparent materials will henceforth work as specified by the material flag, until the scenemanager attribute is set to false.
SMaterialLayer.h
The texture matrix now uses irrAllocator for memory handling. This shouldn't be noticeable from the user application (besides fixed heap corruptions on Windows machines), but is still mentioned for completeness.
ISceneNode.h
Documentation error. The docs said that children of a scene node are not visible if the node itself is set to visible. This is of course wrong, children inherit non-visibility of the parent and are hence invisible if the parent is. If the parent is visible, the visibility flag of the child determines its status.
SColor.h
Removed methods (use the unsigned versions and cast in your app if necessary)
inline s32 getRedSigned(u16 color)
inline s32 getGreenSigned(u16 color)
inline s32 getBlueSigned(u16 color)
IParticleSystemSceneNode.h
Changed default values (the old direction default was no real direction)
virtual IParticleAnimatedMeshSceneNodeEmitter* createAnimatedMeshSceneNodeEmitter(...)
virtual IParticleCylinderEmitter* createCylinderEmitter(...)
virtual IParticleMeshEmitter* createMeshEmitter(...)
IBoneSceneNode.h
Changed signature (Made const)
virtual E_BONE_SKINNING_SPACE getSkinningSpace() const=0;
IrrlichtDevice.h
Changed signature (Return value bool instead of void). Returns whether the event has been handled somewhere.
virtual bool postEventFromUser(const SEvent& event) = 0;

This Tutorial shows how to set up the IDE for using the
Irrlicht Engine and how to write a simple HelloWorld
program with it. The program will show how to use the
basics of the VideoDriver, the GUIEnvironment and the

Microsoft Visual C++ 6.0 and .NET is used as

if you are using a different one or even another operating
system than windows.
This Tutorial shows how to set up the IDE for using the Irrlicht Engine and how

the basics of the VideoDriver, the GUIEnvironment, and the SceneManager.
Microsoft Visual Studio is used as an IDE, but you will also be able to
understand everything if you are using a different one or even another
operating system than windows.
To use the engine, we will have to include the header file
irrlicht.h, which can be found in the Irrlicht Engine SDK
directory \include.
To let the compiler find this header file, the directory where
it is located should be specified somewhere. This is different
for every IDE and compiler you use. I explain shortly how to
do this in Microsift Visual Studio C++ 6.0 and .NET:
You have to include the header file <irrlicht.h> in order to use the engine. The
header file can be found in the Irrlicht Engine SDK directory \c include. To let
the compiler find this header file, the directory where it is located has to be
specified. This is different for every IDE and compiler you use. Let's explain
shortly how to do this in Microsoft Visual Studio:
- If you use Version 6.0, select the Menu Extras -> Options.
- If you use Version 6.0, select the Menu Extras -> Options.
Select the directories tab, and select the 'Include' Item in the combo box.
Add the \include directory of the irrlicht engine folder to the list of directories.
Now the compiler will find the Irrlicht.h header file. We also
need the irrlicht.lib to be found, so stay
in that dialog, select 'Libraries' in the combo box and add the
\lib\VisualStudio directory.
Add the \c include directory of the irrlicht engine folder to the list of
directories. Now the compiler will find the Irrlicht.h header file. We also
need the irrlicht.lib to be found, so stay in that dialog, select 'Libraries'
in the combo box and add the \c lib/VisualStudio directory.

\image latex "vc6optionsdir.jpg"
\image html "vc6include.jpg"
\image latex "vc6include.jpg"
- If your IDE is Visual Studio .NET, select Tools -> Options.
Select the projects entry and then select VC++ directories.
Select 'show directories for include files' in the combo box, and
add the \include directory of the irrlicht engine folder to the list of directories.
Now the compiler will find the Irrlicht.h header file. We also
need the irrlicht.lib to be found, so stay
in that dialog, select 'show directories for Library files' and add the
\lib\VisualStudio directory.

this scene node, irr::scene::ISceneNode::getMaterialCount() returns the
amount of materials in this scene node (our tetraeder only has one
material), and irr::scene::ISceneNode::getMaterial() returns the
material at an index. Because we have only one material here, we can
return the only one meterial, assuming that no one ever calls getMaterial()
with an index greater than 0.

In this tutorial, I will show how to detect collisions with the Irrlicht Engine.
I will describe 3 methods: Automatic collision detection for moving through 3d
worlds with stair climbing and sliding, manual triangle picking, and manual
scene node picking.
To start, we take the program from tutorial 2, which loaded and displayed a quake 3
level. We will use the level to walk in it and to pick triangles from it. In addition
we'll place 3 animated models into it for scene node picking. The following code
starts up the engine and loads
a quake 3 level. I will not explain it, because it should already be known from tutorial
2.

So far so good, we've loaded the quake 3 level like in tutorial 2. Now, here
comes something different: We create a triangle selector. A triangle selector
is a class which can fetch the triangles from scene nodes for doing different
things with them, for example collision detection. There are different triangle
selectors, and all can be created with the ISceneManager. In this example,
we create an OctTreeTriangleSelector, which optimizes the triangle output a
little bit by reducing it like an octree. This is very useful for huge meshes
like quake 3 levels.
After we created the triangle selector, we attach it to the q3node. This is not
necessary, but in this way, we do not need to care for the selector, for example
dropping it after we do not need it anymore.

We add a first person shooter camera to the scene for being able to move in the quake 3
level like in tutorial 2. But this, time, we add a special animator to the
camera: A Collision Response animator. This thing modifies the scene node to which
it is attached to in that way, that it may no more move through walls and is affected
by gravity. The only thing we have to tell the animator is how the world looks like,
how big the scene node is, how gravity and so on. After the collision response animator
is attached to the camera, we do not have to do anything more for collision detection,
anything is done automaticly, all other collision detection code below is for picking.
And please note another cool feature: The collsion response animator can be attached
also to all other scene nodes, not only to cameras. And it can be mixed with other
scene node animators. In this way, collision detection and response in the Irrlicht
engine is really, really easy.
Now we'll take a closer look on the parameters of createCollisionResponseAnimator().
The first parameter is the TriangleSelector, which specifies how the world, against
collision detection is done looks like. The second parameter is the scene node, which
is the object, which is affected by collision detection, in our case it is the camera.
The third defines how big the object is, it is the radius of an ellipsoid. Try it out
and change the radius to smaller values, the camera will be able to move closer to walls
after this. The next parameter is the direction and speed of gravity. You could
set it to (0,0,0) to disable gravity. And the last value is just a translation: Without
this, the ellipsoid with which collision detection is done would be around the camera,
and the camera would be in the middle of the ellipsoid. But as human beings, we are
used to have our eyes on top of the body, with which we collide with our world, not
in the middle of it. So we place the scene node 50 units over the center of the
ellipsoid with this parameter. And that's it, collision detection works now.

The next special effect is a lot more interesting: A particle system. The particle
system in the Irrlicht Engine is quit modular and extensible and yet easy to use.
There is a particle system scene node into which you can put particle emitters, which
make particles come out of nothing. These emitters are quite flexible and usually have
lots of parameters like direction, amount and color of the particles they should create.
There are different emitters, for example a point emitter which lets particles pop out
at a fixed point. If the particle emitters available in the engine are not enough for
you, you can easily create your own ones, you'll simply have to create a class derived
from the IParticleEmitter interface and attach it to the particle system using setEmitter().
In this example we create a box particle emitter, which creates particles randomly
inside a box. The parameters define the box, direction of the particles, minimal and
maximal new particles per second, color and minimal and maximal livetime of the particles.

Because only with emitters particle system would be a little bit boring,
there are particle affectors, which modify particles during they fly around. They can
be added to the particle system, simulating additional effects like gravity or wind.
The particle affector we use in this example is an affector, which modifies the color
of the particles: It lets them fade out. Like the particle emitters, additional
particle affectors can also be implemented by you, simply derive a class from
IParticleAffector and add it with addAffector().

After we set a nice material to the particle system, we have a cool looking camp fire.
By adjusting material, texture, particle emitter and affector parameters, it is also
easily possible to create smoke, rain, explosions, snow, and so on.
Because only with emitters particle system would be a little bit
boring, there are particle affectors which modify particles while
they fly around. Affectors can be added to a particle system for
simulating additional effects like gravity or wind.
The particle affector we use in this example is an affector which
modifies the color of the particles: It lets them fade out. Like the
particle emitters, additional particle affectors can also be
implemented by you, simply derive a class from IParticleAffector and
add it with addAffector().

Now lets create the new materials.
As you maybe know from previous examples, a material type in the Irrlicht engine
is set by simply changing the MaterialType value in the SMaterial struct. And this
value is just a simple 32 bit value, like video::EMT_SOLID. So we only need the
engine to create a new value for us which we can set there.
To do this, we get a pointer to the IGPUProgrammingServices and call
addShaderMaterialFromFiles(), which returns such a new 32 bit value. That's all.
The parameters to this method are the following:
First, the names of the files containing the code of the vertex and the pixel shader.
If you would use addShaderMaterial() instead, you would not need file names, then you
could write the code of the shader directly as string.
The following parameter is a pointer to the IShaderConstantSetCallBack class we wrote
at the beginning of this tutorial. If you don't want to set constants, set this to 0.
The last paramter tells the engine which material it should use as base material.
To demonstrate this, we create two materials with a different base material, one
with EMT_SOLID and one with EMT_TRANSPARENT_ADD_COLOR.

the files containing the code of the vertex and the pixel shader. If
you would use addShaderMaterial() instead, you would not need file
names, then you could write the code of the shader directly as string.
The following parameter is a pointer to the IShaderConstantSetCallBack
class we wrote at the beginning of this tutorial. If you don't want to
set constants, set this to 0. The last paramter tells the engine which
material it should use as base material.
To demonstrate this, we create two materials with a different base
material, one with EMT_SOLID and one with EMT_TRANSPARENT_ADD_COLOR.

This tutorial will briefly show how to use the terrain renderer of Irrlicht. It will also

Note that the Terrain Renderer in Irrlicht is based on Spintz' GeoMipMapSceneNode, lots
of thanks go to him.

-> terrain smoothing.

an event listener to listen if the user presses the 'W' key so we can switch to wireframe
mode and if he presses 'D' we toggle to material between solid and detail mapped.
This tutorial will briefly show how to use the terrain renderer of Irrlicht. It
will also show the terrain renderer triangle selector to be able to do
collision detection with terrain.
Note that the Terrain Renderer in Irrlicht is based on Spintz'
GeoMipMapSceneNode, lots of thanks go to him. DeusXL provided a new elegant
simple solution for building larger area on small heightmaps -> terrain
smoothing.
In the beginning there is nothing special. We include the needed header files
and create an event listener to listen if the user presses a key: The 'W' key
switches to wireframe mode, the 'P' key to pointcloud mode, and the 'D' key
toggles between solid and detail mapped material.

The only parameter we use is a file name to the heightmap we use. A heightmap

the 3D terrain from it.
To make the terrain look more big, we change the scale factor of it to (40, 4.4, 40).
Because we don't have any dynamic lights in the scene, we switch off the lighting,
and we set the file terrain-texture.jpg as texture for the terrain and

the scale values for the texture: The first texture will be repeated only one time over
the whole terrain, and the second one (detail map) 20 times.

/** Example 018 Splitscreen
A tutorial by Max Winkel.
In this tutorial we'll learn how to use splitscreen (e.g. for racing-games)
with Irrlicht. We'll create a viewport divided
into 4 parts, wtih 3 fixed cameras and one user-controlled.
Ok, let's start with the headers (I think there's
nothing to say about it)
*/
#include <irrlicht.h>
#include <stdio.h>
#ifdef _MSC_VER
#pragma comment(lib, "Irrlicht.lib")
#endif
//Namespaces for the engine
using namespace irr;
using namespace video;
using namespace core;
using namespace scene;
using namespace io;
using namespace gui;
/*
Now we'll define the resolution in a constant for use in
initializing the device and setting up the viewport. In addition
we set up a global variable saying splitscreen is active or not.
*/
//Resolution
const int ResX=800;
const int ResY=600;
const bool fullScreen=false;
//Use SplitScreen?
bool SplitScreen=true;
/*
Now we need four pointers to our cameras which are created later:
*/
//cameras
ICameraSceneNode *camera[4]={0,0,0,0};
/*
In our event-receiver we switch the SplitScreen-variable,
whenever the user press the S-key. All other events are sent
to the FPS camera.
*/
class MyEventReceiver : public IEventReceiver {
public:
virtual bool OnEvent(const SEvent& event)
{
//Key S enables/disables SplitScreen
if (event.EventType == irr::EET_KEY_INPUT_EVENT &&
event.KeyInput.Key == KEY_KEY_S && event.KeyInput.PressedDown)
{
SplitScreen = !SplitScreen;
return true;
}
//Send all other events to camera4
if (camera[3])
return camera[3]->OnEvent(event);
return false;
}
};
/*
Ok, now the main-function:
First, we initialize the device, get the SourceManager and
VideoDriver, load an animated mesh from .md2 and a map from
.pk3. Because that's old stuff, I won't explain every step.
Just take care of the maps position.
*/
int main()
{
//Instance of the EventReceiver
MyEventReceiver receiver;
//Initialise the engine
IrrlichtDevice *device = createDevice(EDT_OPENGL,
dimension2d<s32>(ResX,ResY), 32, fullScreen,
false, false, &receiver);
ISceneManager *smgr = device->getSceneManager();
IVideoDriver *driver = device->getVideoDriver();
//Load model
IAnimatedMesh *model = smgr->getMesh("../../media/sydney.md2");
if (!model)
return 1;
IAnimatedMeshSceneNode *model_node = smgr->addAnimatedMeshSceneNode(model);
//Load texture
ITexture *texture = driver->getTexture("../../media/sydney.bmp");
model_node->setMaterialTexture(0,texture);
//Disable lighting (we've got no light)
model_node->setMaterialFlag(EMF_LIGHTING,false);
//Load map
device->getFileSystem()->addZipFileArchive("../../media/map-20kdm2.pk3");
IAnimatedMesh *map = smgr->getMesh("20kdm2.bsp");
if (map)
{
ISceneNode *map_node = smgr->addOctTreeSceneNode(map->getMesh(0));
//Set position
map_node->setPosition(vector3df(-850,-220,-850));
}
/*
Now we create our four cameras. One is looking at the model
from the front, one from the top and one from the side. In
addition there's a FPS-camera which can be controlled by the
user.
*/
// Create 3 fixed and one user-controlled cameras
//Front
camera[0] = smgr->addCameraSceneNode(0, vector3df(50,0,0), vector3df(0,0,0));
//Top
camera[1] = smgr->addCameraSceneNode(0, vector3df(0,50,0), vector3df(0,0,0));
//Left
camera[2] = smgr->addCameraSceneNode(0, vector3df(0,0,50), vector3df(0,0,0));
//User-controlled
camera[3] = smgr->addCameraSceneNodeFPS();
/*
Create a variable for counting the fps and hide the mouse:
*/
//Hide mouse
device->getCursorControl()->setVisible(false);
//We want to count the fps
int lastFPS = -1;
/*
There wasn't much new stuff - till now!
Only by defining four cameras, the game won't be splitscreen.
To do this you need several steps:
- Set the viewport to the whole screen
- Begin a new scene (Clear screen)
- The following 3 steps are repeated for every viewport in the splitscreen
- Set the viewport to the area you wish
- Activate the camera which should be "linked" with the viewport
- Render all objects
- If you have a GUI:
- Set the viewport the whole screen
- Display the GUI
- End scene
Sounds a little complicated, but you'll see it isn't:
*/
while(device->run())
{
//Set the viewpoint to the whole screen and begin scene
driver->setViewPort(rect<s32>(0,0,ResX,ResY));
driver->beginScene(true,true,SColor(255,100,100,100));
//If SplitScreen is used
if (SplitScreen)
{
//Activate camera1
smgr->setActiveCamera(camera[0]);
//Set viewpoint to the first quarter (left top)
driver->setViewPort(rect<s32>(0,0,ResX/2,ResY/2));
//Draw scene
smgr->drawAll();
//Activate camera2
smgr->setActiveCamera(camera[1]);
//Set viewpoint to the second quarter (right top)
driver->setViewPort(rect<s32>(ResX/2,0,ResX,ResY/2));
//Draw scene
smgr->drawAll();
//Activate camera3
smgr->setActiveCamera(camera[2]);
//Set viewpoint to the third quarter (left bottom)
driver->setViewPort(rect<s32>(0,ResY/2,ResX/2,ResY));
//Draw scene
smgr->drawAll();
//Set viewport the last quarter (right bottom)
driver->setViewPort(rect<s32>(ResX/2,ResY/2,ResX,ResY));
}
//Activate camera4
smgr->setActiveCamera(camera[3]);
//Draw scene
smgr->drawAll();
driver->endScene();
/*
As you can probably see, the image is rendered for every
viewport seperately. That means, that you'll loose much performance.
Ok, if you're aksing "How do I have to set the viewport
to get this or that screen?", don't panic. It's really
easy: In the rect-function you define 4 coordinates:
- X-coordinate of the corner left top
- Y-coordinate of the corner left top
- X-coordinate of the corner right bottom
- Y-coordinate of the corner right bottom
That means, if you want to split the screen into 2 viewports
you would give the following coordinates:
- 1st viewport: 0,0,ResX/2,ResY
- 2nd viewport: ResX/2,0,ResX,ResY
If you didn't fully understand, just play arround with the example
to check out what happens.
Now we just view the current fps and shut down the engine,
when the user wants to:
*/
//Get and show fps
if (driver->getFPS() != lastFPS)
{
lastFPS = driver->getFPS();
wchar_t tmp[1024];
swprintf( tmp, 1024, L"Irrlicht SplitScreen-Example (FPS: %d)", lastFPS);
device->setWindowCaption(tmp);
}
}
//Delete device
device->drop();
return 0;
}
/*
That's it! Just compile and play around with the program.
Note: With the S-Key you can switch between using splitscreen
and not.

handle keyboard events in Irrlicht. Here we'll handle mouse events
and joystick events, if you have a joystick connected and a device
that supports joysticks. These are currently Windows, Linux and SDL

In this tutorial, I will show how to collision detection with the Irrlicht
Engine. I will describe 3 methods: Automatic collision detection for moving
through 3d worlds with stair climbing and sliding, manual triangle picking and
manual scene node picking.
To start, we take the program from tutorial 2, which loaded and displayed a quake 3
level. We will use the level to walk in it and to pick triangles from it. In addition
we'll place 3 animated models into it for scene node picking. The following code
starts up the engine and loads
a quake 3 level. I will not explain it, because it should already be known from tutorial
2.

We add a first person shooter camera to the scene for being able to move in the quake 3
level like in tutorial 2. But this, time, we add a special animator to the
camera: A Collision Response animator. This thing modifies the scene node to which
it is attached to in that way, that it may no more move through walls and is affected
by gravity. The only thing we have to tell the animator is how the world looks like,
how big the scene node is, how gravity and so on. After the collision response animator
is attached to the camera, we do not have to do anything more for collision detection,
anything is done automaticly, all other collision detection code below is for picking.
And please note another cool feature: The collsion response animator can be attached
also to all other scene nodes, not only to cameras. And it can be mixed with other
scene node animators. In this way, collision detection and response in the Irrlicht
engine is really, really easy.
Now we'll take a closer look on the parameters of createCollisionResponseAnimator().
The first parameter is the TriangleSelector, which specifies how the world, against
collision detection is done looks like. The second parameter is the scene node, which
is the object, which is affected by collision detection, in our case it is the camera.
The third defines how big the object is, it is the radius of an ellipsoid. Try it out
and change the radius to smaller values, the camera will be able to move closer to walls
after this. The next parameter is the direction and speed of gravity. You could
set it to (0,0,0) to disable gravity. And the last value is just a translation: Without
this, the ellipsoid with which collision detection is done would be around the camera,
and the camera would be in the middle of the ellipsoid. But as human beings, we are
used to have our eyes on top of the body, with which we collide with our world, not
in the middle of it. So we place the scene node 50 units over the center of the
ellipsoid with this parameter. And that's it, collision detection works now.
