Catchy title right? Don't worry, content partly matches to that description... ;)
It seems that I quite often include videos in my blog posts. There is no reason to stray away from that habit now, so here's a video showing a beta version of "Smoke the Bugs!" game on N950 & N8:
To work on current Harmattan & Symbian devices, game uses Qt 4.7 with the shaders plugin. This is an okay-ish platform, as you see from the video: N8@680MHz runs at smooth ~60fps. But I have also smelled, tasted and floated in the sweet velvet of Qt5 and can tell you as a fact that it will be much better. With Qt5 & QtQuick 2.0, applications will get a healthy boost of performance, smoothness and possibility for even better effects.
Here is a short list of improvements QtQuick-based games will gain from Qt5:
- Performance: QML Scene Graph will render everything faster than Qt4 QGraphicsView-based renderer, especially when the amount and complexity of (animated) items rises.
- Smoothness: Qt5 moves rendering into a separate thread which makes UI feel much smoother.
- Effects: QtQuick 2.0 supports shader effects to make QML UI's much more dynamic. Using shaders with Qt4 is possible with the shader plugin as shown above, but Qt5 native support will be more complete.
- Particles: QtQuick 1.0 contains particles plugin but it's very basic when compared to QtQuick 2.0 particles. No game can survive without particles!
- QML features: There are additions in QML which will suit games very well like SpriteImage for sprite animations and PathAnimation & PathInterpolator to animate along a custom path instead of linear path.
- QtCreator: Had to mention this one still as the work done in QtCreator Qt5 integration, QML debugger & analyzer etc. will improve the developer (that's me) productivity.
Now look at the video again to see what the old 2011 QML looked like, add all the above improvements to it and use your imagination... For me it feels like Qt5 & QtQuick 2.0 can offer a great platform not just for applications but also for games. Billion or two, I don't really care... ;) Happy New Year 2012 Everyone!
