I am a TOTAL noob in android coding.
SO I have to make this game...
The game is basically a 2D space invaders primitive clone.
There will be a set no. of enemies to shoot down that come towards you constantly.
I need to know how to do the following:-
1) Generate enemies on the screen at random positions at the top and make them fly towards the bottom
2) Make my player shoot bullets
3) make the enemies disappear if they touch bullets
