Question

I am going to make a Tetris clone. In order to make it look more authentic, I want to draw it in a 160×144 area, but scale it to a 640×576 (scaled 4x), so that every pixel looks like 4 pixels. How can I do this?

Answer 1

If you’re using simple, straightforward Graphics and Graphics2D objects, then drawing a simple square may suffice.

gfx.fillRect(x, y, width, height)

I’ll write a method to do this for myself to make things easier, i.e.

final static int SIZE = 4;

...

public void drawBigPixel(int x, int y, Color col) {
   gfx.setColor(col);
   gfx.fillRect(x * SIZE, y * SIZE, SIZE, SIZE);
}
