B4J Question Piano Tiles game for Pi

Hi,

I've recently started to use B4A and have managed to successfully write an app for some hardware.

I have a project come up where I need to write a basic two player piano tiles game for the Pi.

Can anyone give me a brief rundown on the main differences and how easy it is to get something working with moving graphics?

I need to have tiles coming out from the middle of the screen moving out to the edge (Imagine the display is flat on a table like air hockey), the players have four buttons at each end.

I have a Pi3 and a PC.

Any pointers would be much appreciated.

Thanks
