You are a professional game developer. Please update my 2D space shooter so that each temporary power-up icon is loaded at runtime from the project’s Assets folder rather than hard-coded. The AI should generate: - A `PowerUpUI` manager that, on startup, scans `Assets/PowerUps/Icons/` for all PNG files and builds a dictionary mapping each file name (without extension) to a Sprite. - A `GetIconSprite(string id)` method that returns the corresponding sprite or a default placeholder if the file isn’t found. - A `ShowPowerUp(string id, float duration)` function that: 1. Retrieves the icon via `GetIconSprite(id)` 2. Instantiates it in the next available UI slot (with image and countdown text) 3. Starts a 10-second timer updating the countdown every second 4. On expiry, plays a fade-out animation and removes the slot, shifting remaining icons left. - Instructions for designers to add or replace icons simply by dropping PNGs named after the power-up IDs into `Assets/PowerUps/Icons/`. Structure the response into: 1. Project setup & asset folder layout 2. Runtime asset loading logic 3. UI slot management & countdown 4. Designer instructions for adding icons Provide this as a complete prompt for an AI code generator—no implementation code itself, just the prompt text.```

You are a professional game developer. Please update the 2D space shooter game so that temporary power-ups (boosts) appear visibly on screen with customizable icons. Follow these requirements:
1. **Power-Up UI Slot**
- Reserve a fixed area (e.g. top-right corner) showing up to three active power-up slots.
- Each slot displays an icon image, a border or background frame, and a small countdown timer underneath.
2. **Customizable Icons**
- Load icon textures from an “Assets/PowerUps/Icons” folder.
- In code, reference each icon by filename (e.g. “speed_boost.png”, “double_shot.png”, “invincible.png”).
- If no custom icon is provided, use a default placeholder sprite.
3. **Power-Up Activation & Expiry**
- When the player collects a boost:
- Instantiate its icon in the next empty slot.
- Start a 10-second timer that updates the countdown text every second.
- When the timer reaches zero:
- Play an expiry animation (e.g. icon fades out).
- Remove the icon and shift any remaining slots to fill gaps.
4. **Implementation Details**
- In [your chosen framework/language], create a `PowerUpUI` manager class or module that:
- Holds references to UI slot GameObjects or canvas elements.
- Provides `ShowPowerUp(type, duration)` and `HidePowerUp(type)` methods.
- Example pseudocode for Unity C#:
```csharp
public void ShowPowerUp(string type, float duration) {
var slot = GetNextEmptySlot();
var icon = Resources.Load

You are a professional game developer. Please generate a complete 2D shooter game based on the following enhanced specifications: 1. **Core Gameplay & Progression** - Start with a gentle difficulty: slow enemy spawn rate, easy movement patterns. - As the player’s score increases or time passes, gradually ramp up difficulty by spawning more enemies, increasing their speed, and adding complex behaviors. 2. **Temporary Power-Ups (10-Second Duration)** - **Speed Boost**: Doubles player ship movement speed for 10 seconds. - **Double Shot**: Fires two bullets per shot for 10 seconds. - **Invincibility**: Player ship is immune to damage for 10 seconds. - **Other Ideas**: Rapid-fire (increased fire rate), shield recharge, score multiplier. 3. **Power-Up Spawning** - Power-ups appear at random positions, drifting downward like enemies. - Only one power-up active on screen at a time; new one spawns 5–8 seconds after the previous expires or is collected. - Use distinct icons/colors for each power-up type. 4. **Implementation Requirements** - Include code examples in [your chosen framework/language] (e.g., Unity C#, HTML5 Canvas + JS, Godot GDScript). - Show how to: - Track and trigger difficulty scaling (by score or time). - Spawn and time-limit power-ups. - Apply and expire each boost effect cleanly. - Update UI to display active boost icon and remaining duration. 5. **UI & Feedback** - Display player score and kill count at top. - Show small icons for active boosts with a countdown timer. - Play distinct sound and particle effects when picking up and when boost expires. Structure your response into clear sections: - Project Setup - Difficulty Progression System - Power-Up Types & Logic - Input & Controls - UI & Effects - Build & Export Instructions Thank you!
