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:

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 your code would look like. I finally ended up with Continue reading Initial Landscape orientation issue on iOS solved

Objective-C Memory Management

coders

Every object that is derived from NSObject has the ability to be managed by retain counting. When an object is created (alloc) the system will allocate memory for the object and set a retain count to 1. The count can be incremented when a new instance of this object exist (assignment for example) and decrement when an object instance is released. Once the retain count is going to zero the object will be destructed and the memory gets freed. This post is Continue reading Objective-C Memory Management

Disconnect SVN repository

If you want to “disconnect” your SVN repository from your current project you could use the export function of svn:

But this will just export the repository. All uncommitted changes will be lost. 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”

Hint: Always make a backup before you use this script

 

Fast realtime shadows in Unity

plane_shadow1

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
