After this, add the following code:
public Sprite[] testSprites;
public int selectedSprite;
public WorldController () {
init();
}
private void init () {
initTestObjects();
}
private void initTestObjects() {
// Create new array for 5 sprites
testSprites = new Sprite[5];
// Create empty POT-sized Pixmap with 8 bit RGBA pixel data
int width = 32;
int height = 32;
Pixmap pixmap = createProceduralPixmap(width, height);
// Create a new texture from pixmap data
Texture texture = new Texture(pixmap);
// Create new sprites using the just created texture
for (int i = 0; i < testSprites.length; i++) {
Sprite spr = new Sprite(texture);
// Define sprite size to be 1m x 1m in game world
spr.setSize(1, 1);
// Set origin to sprite's center
spr.setOrigin(spr.getWidth() / 2.0f, spr.getHeight() / 2.0f);
// Calculate random position for sprite
float randomX = MathUtils.random(-2.0f, 2.0f);
float randomY = MathUtils.random(-2.0f, 2.0f);
spr.setPosition(randomX, randomY);
// Put new sprite into array
testSprites[i] = spr;
}
// Set first sprite as selected one
selectedSprite = 0;
}
private Pixmap createProceduralPixmap (int width, int height) {
Pixmap pixmap = new Pixmap(width, height, Format.RGBA8888);
// Fill square with red color at 50% opacity
