问题 Hi Guys I have 2 activities, 1 is in Android Native(Extends Activity) and 2 is in LIBGdx extends AndroidApplication.

When I'm now changing the Screen to the actual Game-Screen, my device just blackscreens. This Screen contains a Box2d World with lots of Objects, a big Texture

问题 I'm trying to do a card flip animation in Libgdx. Sprites and Actors support only rotation clockwise/counter-clockwise. So I thought that I can achieve that by using the Rotate function in the camera object. The problem is that it affects the whole stage and not just the actor. How can I achieve this affect without creating a new stage? 回答1: Well you have never defined what the back side of a card looks like, since actors are just images ;) What you could do is to use two images, one for the

问题 I am trying to add a simple library like json.org to my libgdx project. The dependencies were properly configured in the gradle file. The project is not compiling any longer. I think the problem is because the GWT compiler is not able to find the source code. Did this happen to someone else before? Any possible solution? Thanks. 回答1: What errors are you getting ? Try to issue the command from the command line: gradlew --refresh-dependencies Got this one from the Universal Tween Engine
