How do I

Hey. I want to do a game in vertical. What is the resolution for Android Games in vertical? And how I do a gamee with a view like you were in helicopter. Top view

Android has many different resolutions, so it's best to target multiple screensizes.

Choosing the right movement behaviour depends on what you would like.

For top view you could use 8-direction, car, bullet and maybe even pathfinding, depending on the effect you'd like.

Adding some conditions you could tweak these behaviours to do almost anything you want.

I want a game with 3 roads. The player has a car going walking in the wrong lane and have to dodge the cars coming . Do you know of any tutorial so the type ?

I don't, but the mechanics shouldn't be that hard..
