IrrlichtMt version 1.9
======================
IrrlichtMt is the 3D engine of [Minetest](https://github.com/minetest).
It is based on the [Irrlicht Engine](https://irrlicht.sourceforge.io/) but is now developed independently.
It is intentionally not compatible to upstream and is planned to be eventually absorbed into Minetest.
Build
-----
The build system is CMake.
The following libraries are required to be installed:
* zlib, libPNG, libJPEG
* OpenGL
* or on mobile: OpenGL ES (can be optionally enabled on desktop too)
* on Unix: X11
* SDL2 (see below)
Aside from standard search options (`ZLIB_INCLUDE_DIR`, `ZLIB_LIBRARY`, ...) the following options are available:
* `BUILD_SHARED_LIBS` (default: `ON`) - Build IrrlichtMt as a shared library
* `BUILD_EXAMPLES` (default: `OFF`) - Build example applications
* `ENABLE_OPENGL` - Enable OpenGL driver
* `ENABLE_OPENGL3` (default: `OFF`) - Enable OpenGL 3+ driver
* `ENABLE_GLES1` - Enable OpenGL ES driver, legacy
* `ENABLE_GLES2` - Enable OpenGL ES 2+ driver
* `USE_SDL2` (default: platform-dependent, usually `ON`) - Use SDL2 instead of older native device code
e.g. on a Linux system you might want to build for local use like this:
git clone https://github.com/minetest/irrlicht
cd irrlicht
cmake . -DBUILD_SHARED_LIBS=OFF
make -j$(nproc)
This will put an IrrlichtMtTargets.cmake file into the cmake directory in the current build directory, and it can then be imported from another project by pointing `find_package()` to the build directory, or by setting the `CMAKE_PREFIX_PATH` variable to that same path.
on Windows system:
It is highly recommended to use vcpkg as package manager.
After you successfully built vcpkg you can easily install the required libraries:
vcpkg install zlib libjpeg-turbo libpng sdl2 --triplet x64-windows
Run the following script in PowerShell:
git clone https://github.com/minetest/irrlicht
cd irrlicht
cmake -B build -G "Visual Studio 17 2022" -A "Win64" -DCMAKE_TOOLCHAIN_FILE=[vcpkg-root]/scripts/buildsystems/vcpkg.cmake -DBUILD_SHARED_LIBS=OFF
cmake --build build --config Release
Platforms
---------
We aim to support these platforms:
* Windows via MinGW
* Linux (GL or GLES)
* macOS
* Android
This doesn't mean other platforms don't work or won't be supported, if you find something that doesn't work contributions are welcome.
License
-------
The license of the Irrlicht Engine is based on the zlib/libpng license and applies to this fork, too.

To make Irrlicht run inside the custom window, you still will
have to draw Irrlicht on your own. You can use this loop, as
usual:
\code
while (device->run())
{
driver->beginScene(video::ECBF_COLOR | video::ECBF_DEPTH, 0);
smgr->drawAll();
driver->endScene();
}
\endcode
Instead of this, you can also simply use your own message loop
using GetMessage, DispatchMessage and whatever. Calling
IrrlichtDevice::run() will cause Irrlicht to dispatch messages
internally too. You need not call Device->run() if you want to
do your own message dispatching loop, but Irrlicht will not be
able to fetch user input then and you have to do it on your own
using the window messages, DirectInput, or whatever. Also,
you'll have to increment the Irrlicht timer.
An alternative, own message dispatching loop without
device->run() would look like this:
\code
MSG msg;
while (true)
{
if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
if (msg.message == WM_QUIT)
break;
}
// increase virtual timer time
device->getTimer()->tick();
// draw engine picture
driver->beginScene(video::ECBF_COLOR | video::ECBF_DEPTH, 0);
smgr->drawAll();
driver->endScene();
}
\endcode

do it how you like. */
