How to go about creating a race track game? [closed]

Answer 1

I suggest you download AndEngine ( an open source 2d android game develoopmnent framework ). In the examples there is a (very simple) race track demo with a movable car + controls + obstacles. If you have troubles you can always get support from the forums

AndEngine has a very easy learning curve :-)
Have fun creating your racing game!!

Here are 2 good tutorials on starting with 2d:
- Canvas tutorial
- OpenGL tutorial

The last part, about showing only a part of the map, can be achieved by using a BoundCamera in AndEngine.

Answer 2

You should start with studying the 2D graphics capabilities of the Android library. Here's another good reference article. It lists some drawing options including drawing to the Canvas object which is probably the right choice for the kind of game you're describing.

Here's a full but simple example of handling the onDraw event for a canvas and performing custom drawing. Here's a small bit of the code:

        paint.setColor(Color.BLUE);
        canvas.drawCircle(20, 20, 15, paint);

The above is a simple example that draws a circle with a particular size to a particular location on the canvas. It's a good place to start. To finish your game you'll be drawing bitmaps which is a more complex process but conceptually similar.
