The
updateGameOver()
method also checks if the button in the middle of the screen was pressed.
If it has been pressed, then we initiate a screen transition back to the main menu screen.
@Override
public void
present(
float
deltaTime) {
Graphics g = game.getGraphics();
g.drawPixmap(Assets.
background
, 0, 0);
drawWorld(world);
if
(state == GameState.
Ready
)
drawReadyUI();
if
(state == GameState.
Running
)
drawRunningUI();
if
(state == GameState.
Paused
)
drawPausedUI();
if
(state == GameState.
GameOver
)
drawGameOverUI();
drawText(g, score, g.getWidth() / 2 - score.length()*20 / 2, g.getHeight() - 42);
}
Next up are the rendering methods. The
present()
method first draws the background image, as
that is needed in all states. Next, it calls the respective drawing method for the state we are in.
Finally, it renders Mr. Nom's world and draws the score at the bottom-center of the screen.
private void
drawWorld(World world) {
Graphics g = game.getGraphics();
Snake snake = world.snake;
SnakePart head = snake.parts.get(0);
Stain stain = world.stain;
Pixmap stainPixmap =
null
;
if
(stain.type == Stain.
TYPE_1
)
stainPixmap = Assets.
stain1
;
