Rotateable cameras

[Nicolas Gramlich]

Oh man, that last bug almost made me scratch my eyes out ... but I got it working now

[Edit]Ok trust me now it works [/Edit]

So... 100x stupid sign-errors later you can do stupid stuff like, rotating menus upside down or this:

You can see that you don't have to care about the touch coordinates as they get converted for you

Let me know if you find a bug

Oh crap! This is awesome.

I'm going to stop my other progress on the game and figure out how to implement this tonight.

thanks! thanks! thanks!

I had quickly had hacked above demo using this code:

Using java Syntax Highlighting

1. this.mEngine.registerUpdateHandler(new TimerHandler(0.01f, true, new ITimerCallback() {
2.         @Override
3.         public void onTimePassed(TimerHandler pTimerHandler) {
4.                 mCamera.setCameraSceneRotation(mCamera.getCameraSceneRotation() + 0.2f);
5.         }
6. }));

Ok, I managed to compile the source, and implement the single line of code in my protogame that makes this work (sorta).

However, rotation is still jerky. I will play with this over the weekend and see how much of the jerkiness is my hack code, and what I can do to smooth things out.

What is the FPS your game is running at

Above code was just a quick hack and definitely not the best solution. Sth like this should work better:

4.                     mCamera.setCameraSceneRotation(mCamera.getCameraSceneRotation() + pSecondsElapsed * ROTATION_PER_SECOND_DEGREES);
5.             }
6.     });

How to set rotation back to normal. ?? like reset( ) but in Camera it is just an empty mothod.

Not 100% sure but how about
