Game Background

Purpose

The new game background is implemented to better fit the game's story setting. Therefore, to provide the player a more immersive gaming experience and more attractive visuals.

Implementation

Key Components

• background images The images that make up the background of the game, background_rock.png, background_star.png, background_stars.png, background_sky.png, background_surface.png.
• TerrainFactory The new background images have to be initialized in createTerrain() and give them actual position in createSideScrollTiles().

Usage

1. Initializing the background images in createTerrain().

case SIDE_SCROLL_ER:
        TextureRegion surface =
                new TextureRegion(resourceService.getAsset("images/background_surface.png", Texture.class));
        TextureRegion underground =
                new TextureRegion(resourceService.getAsset("images/background_rock.png", Texture.class));
        TextureRegion sky =
                new TextureRegion(resourceService.getAsset("images/background_sky.png", Texture.class));
        TextureRegion star =
                new TextureRegion(resourceService.getAsset("images/background_star.png", Texture.class));
        return createSideScrollTerrain(0.5f, surface, underground, sky, star);

2. Arrange the position of each background image in createSideScrollTiles() when they appear in the game.
