Godot Space Ace - High-Performance Arcade Shooter

This is the seventh project in my Godot learning journey. This project pushes the boundaries of "Game Feel" and System Architecture using advanced particle systems, a data-driven Wave Manager, and an optimized Object Factory.

Learning Outcomes

In this project, I focused on high-speed system architecture and visual polish:

• Data-Driven Wave Management: Developed a custom WaveManager that uses structured data to define enemy types, spawn intervals, and formation patterns, allowing for easy difficulty balancing.
• Advanced Object Factory: Expanded the ObjectMaker pattern to handle high-frequency instantiation of projectiles, power-ups, and VFX without performance bottlenecks.
• VFX & Juice: Leveraged CPUParticles2D for sophisticated combat feedback (engine trails, multi-stage explosions, and screen shake), focusing on "Game Feel."
• Collision Layers & Masking: Mastered Godot's physics layers to manage complex interactions between player bullets, enemy projectiles, and environmental hazards.
• Dynamic Resource Despawning: Implemented efficient memory management using VisibleOnScreenNotifier2D and signal-based cleanup to maintain high FPS during intense combat.

Tech Stack

• Engine: Godot 4.5
• Visuals: CPUParticles2D & ParallaxBackground.
• Patterns: Factory Pattern, Data-driven Wave Management, Singleton (SignalHub).

Technical Excellence: Wave Logic & Factory Integration

The following snippet demonstrates how the WaveManager coordinates with the ObjectMaker to create structured gameplay flow instead of simple random spawning:

# Professional Wave Control and Object Factory Handshake
func spawn_wave(wave_data: Dictionary) -> void:
    for i in range(wave_data.enemy_count):
        # Using the Factory to instantiate specific enemy types from data
        var enemy = ObjectMaker.create_enemy(wave_data.enemy_type)
        
        # Setting up path-following or position based on wave pattern
        enemy.global_position = Vector2(SCREEN_WIDTH + 100, randf_range(50, 600))
        enemy.set_speed(wave_data.base_speed + (current_wave * 10))
        
        add_child(enemy)
        await get_tree().create_timer(wave_data.spawn_delay).timeout

# VFX trigger via ObjectMaker for 'Juice'
func _on_enemy_destroyed(pos: Vector2) -> void:
    ObjectMaker.create_visual_effect(ObjectMaker.FX_TYPE.EXPLOSION, pos)
    ObjectMaker.create_visual_effect(ObjectMaker.FX_TYPE.SCREEN_SHAKE)
