📜TrashPurge

Motto : Clean to Survive. Recycle to Conquer.

TrashPurge is a high-octane AR action-survival experience that gamifies environmental stewardship. Players defend their real-world surroundings by transforming physical "waste" into tactical resources, bridging the gap between digital combat and global sustainability.

🎮 1. The Core Concept

TrashPurge fuses the frantic energy of wave-based shooters with the urgent necessity of the UN Sustainable Development Goals (SDGs).

The Loop

1. Scan: Detect horizontal planes in your actual room/office.
2. Anchor: Establish a physical "Command Desk" as your UI hub.
3. Collect: Scavenge virtual trash spawned in your real-world space.
4. Convert: Process waste into Ammo or Health at the workstation.
5. Defend: Use your recycled arsenal to repel escalating waves of "Trash-Blights."

High-Level Design Metrics

Feature	Implementation	Strategic Purpose
Mechanical Hook	Collect $\rightarrow$ Recycle $\rightarrow$ Fight	Ties eco-action directly to player survival.
AR Modality	Plane Detection & Spatial Tracking	Forces physical movement and spatial awareness.
Session Flow	Onboarding $\rightarrow$ Tutorial $\rightarrow$ Waves	Ensures low barrier to entry with high replayability.

⚙️ 2. Technical Mechanics & Systems

A. AR Environmental Integration

• Spatial Mapping: Uses real-time plane detection to ground gameplay objects.
• The Hub: A designated desk acts as the "Safe Zone" and primary interaction anchor for the player’s HUD.

B. Resource Economy (The "Clean" Economy)

Players must balance their inventory to stay alive. The choice to convert trash into Health vs. Ammo creates a constant tactical tension.

Resource	Value	behavior
Starting Stats	$15$ HP / $10$ Ammo	Baseline for Wave 1.
Recycle (Ammo)	$+10$ Ammo / Trash	Primary path for offensive sustainability.
Recycle (Health)	$+1$ HP / Trash	Critical path for defensive recovery.
Spawn Logic	Cap: $8$ Items	Prevents visual clutter; maintains frantic pacing.

C. Combat & Wave Scaling

Enemies utilize a Weighted Selection System, meaning as waves progress, the "Blight" composition shifts from simple scouts to heavy-duty environmental threats with scaling Health and Damage.

🌍 3. Global Impact & SDG Alignment

TrashPurge is built to be more than a game—it's a behavioral nudge engine.

Primary Goals

• SDG 11 (Sustainable Cities): Frames waste as a visible, actionable problem in the player’s immediate vicinity.
• SDG 12 (Responsible Production): Simulates the "Circular Economy" by treating waste as a valuable raw material for recovery.
• SDG 13 (Climate Action): Uses gamification to build long-term sub-conscious habits regarding environmental responsibility.

📈 4. Roadmap & Success Metrics (KPIs)

The Impact Funnel

• Phase 1 (Prototype): Validate the "Fun Factor" of recycling mechanics.
• Phase 2 (Playtest): Analyze decision-making under pressure (Do players recycle or panic?).
• Phase 3 (Scale): Educational partnerships and real-world cleanup campaigns.

Key Performance Indicators

• Cleanup Efficiency: $\geq 10$ Trash items collected per session.
• Recycle Engagement: $\geq 5$ Conversion actions per run.
• Survival Floor: Median player reaches Wave 3.
• Retention: $\geq 25\%$ Day-7 return rate via "Daily Cleanup" incentives.
