Leaderboards and sharing functionality enhance engagement by encouraging competition and social interaction. On Day 9, we’ll create a leaderboard to display high scores and implement sharing features so players can share their achievements.
1. Implementing a Leaderboard
Step 1: Create a Leaderboard Data Structure
Use an array to store player scores. In Level1.js, initialize it:
create() {
this.leaderboard = [
{ name: 'Player1', score: 150 },
{ name: 'Player2', score: 120 },
{ name: 'Player3', score: 100 },
];
}
Step 2: Display the Leaderboard
Use Phaser’s Text object to display leaderboard entries:
create() {
this.add.text(10, 10, 'Leaderboard:', { fontSize: '24px', color: '#ffffff' });
this.leaderboard.forEach((entry, index) => {
this.add.text(10, 50 + index * 30, `${index + 1}. ${entry.name}: ${entry.score}`, {
fontSize: '20px',
color: '#ffffff',
});
});
}
Step 3: Update the Leaderboard
Add a method to update and sort the leaderboard:
updateLeaderboard(name, score) {
this.leaderboard.push({ name, score });
this.leaderboard.sort((a, b) => b.score - a.score); // Sort by score descending
this.leaderboard = this.leaderboard.slice(0, 5); // Keep top 5
}
Call this method when a player finishes a level:
this.updateLeaderboard('NewPlayer', 180);
2. Adding Sharing Functionality
Step 1: Generate a Shareable Message
Create a text string summarizing the player’s performance:
generateShareMessage(playerName, score) {
return `I scored ${score} points in Phaser Game! Can you beat my score?`;
}
Step 2: Implement Social Sharing
Integrate social sharing via web links. Add a share button in the create method:
create() {
const message = this.generateShareMessage('Player1', 150);
this.add.text(10, 200, 'Share Score', { fontSize: '20px', color: '#ffffff', backgroundColor: '#007bff' })
.setInteractive()
.on('pointerdown', () => {
const shareURL = `https://twitter.com/intent/tweet?text=${encodeURIComponent(message)}`;
window.open(shareURL, '_blank');
});
}
Replace the twitter.com URL with other social platforms (e.g., Facebook or WhatsApp) as needed.
Step 3: Enable Sharing in React Native
For React Native, use the react-native-share library to enable native sharing:
npm install react-native-share
Update App.js:
import Share from 'react-native-share';
function shareScore(playerName, score) {
const message = `I scored ${score} points in Phaser Game! Can you beat my score?`;
Share.open({
message: message,
}).catch((err) => console.error(err));
}
3. Integrating the Leaderboard and Sharing
Update App.js with Leaderboard and Sharing Logic
Modify the phaserHTML to include leaderboard and sharing functionality:
const phaserHTML = `
<html>
<head>
<script src="https://cdn.jsdelivr.net/npm/phaser@3/dist/phaser.min.js"></script>
<script>
const config = {
type: Phaser.AUTO,
width: 800,
height: 600,
backgroundColor: '#2d2d2d',
scene: {
preload: function () {},
create: function () {
const leaderboard = [
{ name: 'Player1', score: 150 },
{ name: 'Player2', score: 120 },
{ name: 'Player3', score: 100 },
];
this.add.text(10, 10, 'Leaderboard:', { fontSize: '24px', color: '#fff' });
leaderboard.forEach((entry, index) => {
this.add.text(10, 50 + index * 30, \`\${index + 1}. \${entry.name}: \${entry.score}\`, {
fontSize: '20px',
color: '#fff',
});
});
const shareMessage = 'I scored 150 points in Phaser Game! Can you beat my score?';
this.add.text(10, 200, 'Share Score', {
fontSize: '20px',
color: '#fff',
backgroundColor: '#007bff',
})
.setInteractive()
.on('pointerdown', () => {
const shareURL = \`https://twitter.com/intent/tweet?text=\${encodeURIComponent(shareMessage)}\`;
window.open(shareURL, '_blank');
});
},
update: function () {},
},
};
new Phaser.Game(config);
</script>
</head>
<body></body>
</html>
`;
4. Running the Game
Step 1: Start the Development Server
npm start
Step 2: Test Leaderboard and Sharing
- Verify that the leaderboard displays scores correctly.
- Test the share button for generating and sharing messages.
5. Key Concepts Covered
- Creating and managing a leaderboard.
- Integrating social sharing via web links or native libraries.
- Updating game state dynamically with scores and sharing functionality.
Next Steps
On Day 10, we’ll optimize the game for performance and deploy it to mobile platforms like Android and iOS.
