One more thing, is there any way to keep some pixels without a need to draw them evey frame? i mean at the moment i am painitg the whole screen no matter if it changes or not, i think android has something for this invalidate() but can i use it here?

One of my problems is that i dont know what to expect from the device capacity

1. If i find any 2d engine / GUI toolkit can i try to post-render the screen with another engine, and the most important, it will be stable and fast enought?

2. what im trying to do is some kind of chess game, and i need to know where on the table did the player clicked to move, i can create every box like a new object or all the board like 1 object and then calculate where he want to move. If i want to make it shine where is possible to move then i should to it separately?

Thank you

Hi
Im a new user of this engine and i lack a lot of experience with grafic engines or android development, but i want to thank you for this engine and say that its easier to use than expected ( at least till now xD)
I have some questions to you:

- user GUI: i want to have my world in the background that is represented in the camera and over this i would like to have a 2dWorld with the user interface, those are some buttons or some text panel , in some guides that i saw ppl used blit() but that is only some pixel painting , i would like to know if there are something more advanced.

- is there some way to know at what point of the 3dObject i have clicked, at what object but and where at that object

Thank you
