Initial Landscape orientation issue on iOS solved
I have searched for a solution how to implement a ViewController that supports only LandscaleLeft and LandscapeRight mode. Most solutions I found on stackoverflow and other forums using a setOrientationMode selector on the device object: NSNumber *value = [NSNumber numberWithInt: UIInterfaceOrientationLandscapeLeft]; [[UIDevice currentDevice] setValue:value forKey:@”orientation”]; this could probably work for you, but it uses a non official selector. You may think of this: it is impossible for the program to actually physically turn around your device, but that is what Continue reading Initial Landscape orientation issue on iOS solved

The other (in my opinion better) way is just to delete all SVN folders. if you are unsure what this script is really doing you could check via “echo” cd /path/to/your/project find . -name .svn | while read; do echo rm -Rf “$REPLY”; Continue reading Disconnect SVN repository

Fast realtime shadows in Unity
Unity comes with built-in shadow map support, but you shouldn”t expect cutting edge technology. No soft shadows on mobile devices and at least for my current project it is too slow on the GPU. Unfortunately Unity 4.x does not provide many other solutions for realtime shadows. However there is hope that there will be improvements for shadows in Unity 5, but you can’t develop a game on hope can you? I decided to have a fallback solution that is fast Continue reading Fast realtime shadows in Unity
