Of course it is easy if you know what you're doing and if you have practiced a lot. So you need to tell us what you have currently done. Which languages have you learned yet and what have you programmed? Haave you ever worked with DroidScript? Have you ever Programmed? We need to know this so that we know where we should start with our explanation.
You currently have 4 ways to create a game in DroidScript:
1. HTML Canvas - I don't recommend it because you'll need to use a web view and touch handlers as well as the performance won't be very good.
It may be enough for a little game like the Dinosaur demo, but I don't recomend it anyway for mobile devices.
2. Images - A good way for beginners to start with in my point of view. They're not fast too but if you're doing it right it will be the best choice.
3. GLViews - They're very fast and just a bit more difficult to use. There's just one tricky thing you should pay attention on.
This was the best way to make very good performing games until now. But I've noticed that it is consuming much energy.
4. GameView - it is currently in beta state and may change a lot in the future. It uses gles for all graphics and that's one reason why it is the most performant way to make games.
The advantage is, that you have support of many features like sprite sheets, collision detection, physics in general, sound etc. But I wouldn't recomend it for beginners. It is very very hard to understand if you have never coded before because of all these features and it is not very stable in debugging.
So please tell us what your current experience with programming and game development is, and we ay be able to help you with the principles.
