Abstract
( Class names has changed ! This tutorial is currently unvaible )
KGLengine is a powerfull 2d games engine, for people who want to create hight level of games. Instead QGraphicsView system, KGLEngine use all power of openGL and Eigen mathematic library. Now you will be able to create fullscreen games, particles effects for make smoke or explosion, shadow effects, collision detection with a lot of items, and as soon as possible to use Shaders effects.
Installation
First : install eigen2 librairy.
Second, be sure you have libQt4-dev, libQt4-openGL-dev, and kde4-lib devel.
download KGLEngine source from svn :
svn co svn://anonsvn.kde.org/home/kde/trunk/playground/games/KGLEngine
cd kglengine mkdir build cd build cmake .. make; make install;
First program
<syntaxhighlight lang="cpp-qt">
- include <KApplication>
- include <KAboutData>
- include <KCmdLineArgs>
- include <KGLEngine2d>
- include <KGLItem>
using namespace std;
int main(int argc, char *argv[])
{
KAboutData aboutData("kglintro", 0, ki18n("tutorial1"), "1.0", ki18n("engine 2d"), KAboutData::License_GPL, ki18n("Copyright (c) 2009 Developer")); KCmdLineArgs::init(argc, argv, &aboutData); KApplication app;
KGLEngine2d *engine= KGLEngine2d::instance(); //init engine
engine->setShowAxis(true); //show repere line x,y engine->setShowFps(true); //show fps engine->show(); //show window engine
KGLItem * box = new KGLItem(QRectF(0,0,0.5,0.5)); //create an item box->scale(0.5); //reduce the size box->translate(-box->transformCenter()); //translate the box to the center box->rotate(M_PI/4); //rotate it with a radius = 45 deg box->setColor(Qt::white); //setColor! By default, it's white engine->addItem(box); //add item to the engine
app.exec(); return 0;
}
