Add Dyson Sphere - Progressive assembly (Implementation B)

[wannerdev]

Description

Alternative Dyson Sphere implementation with tier-based sun station upgrades and progressive sphere construction animation.

Implementation Approach

This is Implementation B - Progressive Assembly with gradual building and visual progression.

Key Differences from Implementation A

• Tier System: Sun stations upgrade through 3 tiers (not instant activation)
• Progressive Building: Sphere builds gradually (not instant)
• Visual Progression: See sphere forming in real-time with pulsing edge
• More Gradual: Requires more total bricks for completion

Core Mechanics

Brick System

• Bricks spawn every 25 seconds (faster than Implementation A)
• Green-yellow colored for distinction
• Spawn at distance 40 from sun
• Satellites collect on contact

Sun Station Tiers

• Tier 1: 2 bricks (light golden)
• Tier 2: 3 more bricks = 5 total (medium golden)
• Tier 3: 5 more bricks = 10 total (deep golden)
• Each tier changes sprite color progressively
• Visual tier rings around stations

Progressive Sphere Construction

• Starts building at total tier 4 (e.g., 2 tier-2 stations)
• Target completion = total_tier / 12
• Builds at 10% per second toward target
• Reaches 100% at tier 12 total
• Smooth animation with pulsing construction edge

Changes

• Created dyson_sphere_progressive module
• Added tier-based SunStation component
• Added DysonSphere with completion percentage
• Implemented upgrade_sun_stations for tier progression
• Implemented build_dyson_sphere_progressively for gradual start
• Implemented animate_sphere_construction for smooth building
• Added pulsing visual effect on construction edge
• Added tier ring indicators around stations
• Faster brick spawn rate (25s vs 30s)

Visual Effects

Sun Station Tiers

• Tier 1: Light golden (RGB: 1.0, 0.9, 0.3)
• Tier 2: Medium golden (RGB: 1.0, 0.8, 0.2)
• Tier 3: Deep golden (RGB: 1.0, 0.7, 0.1)
• Golden rings around stations (1-3 rings based on tier)

Dyson Sphere Animation

• Builds 10% per second
• Pulsing white effect on construction edge
• Smooth progression from 0% to 100%
• Golden color (RGB: 0.9, 0.9, 0.3)
• Radius: 1.8x sun radius

Brick Indicators

• Small circles above satellites
• Shows up to 5 collected bricks
• Green-yellow color matching brick sprites

Gameplay Flow

1. Bricks spawn every 25 seconds
2. Collect 2 bricks → Tier 1 station
3. Collect 3 more → Tier 2 station (5 total)
4. Collect 5 more → Tier 3 station (10 total)
5. Reach tier 4 total → Sphere starts building
6. Reach tier 12 total → Sphere 100% complete

Progression Examples

• 2 Tier-2 stations: Tier 4 total → 33% sphere
• 1 Tier-3 + 1 Tier-1: Tier 4 total → 33% sphere
• 4 Tier-3 stations: Tier 12 total → 100% sphere
• 2 Tier-3 + 2 Tier-3: Tier 12 total → 100% sphere

Balancing

Brick Requirements

• Tier 1: 2 bricks
• Tier 2: 5 bricks total
• Tier 3: 10 bricks total
• Full sphere: 40 bricks (4 tier-3 stations)

Time Investment

• Brick spawn: 25 seconds each
• Minimum time: ~17 minutes (40 bricks * 25s)
• Construction animation: ~10 seconds per 100%

Benefits Over Implementation A

• More Engaging: Gradual progression feels rewarding
• Visual Feedback: See sphere building in real-time
• Strategic Depth: Choose between many low-tier or few high-tier stations
• Better Pacing: Tier system provides intermediate goals
• More Polished: Animated construction with pulsing effects

Technical Implementation

Tier Upgrade Logic

if bricks >= 2 && tier == 0 -> tier 1
if bricks >= 3 && tier == 1 -> tier 2
if bricks >= 5 && tier == 2 -> tier 3

Sphere Construction

target_completion = total_tier / 12.0
current += 0.1 * delta_time (toward target)

Visual Progression

• Tier rings: 1-3 concentric circles
• Sphere segments: 32 total, drawn based on completion %
• Pulsing: sin wave on construction edge

Testing

• Wait for bricks to spawn (25s intervals)
• Collect 2 bricks → Verify tier 1 activation
• Collect 3 more → Verify tier 2 upgrade
• Collect 5 more → Verify tier 3 upgrade
• Check sphere starts building at tier 4 total
• Verify smooth animation to 100%
• Check pulsing effect on construction edge
• Verify tier rings around stations

Comparison with Implementation A

Feature	Implementation A	Implementation B
Station System	Single activation	3-tier upgrades
Sphere Formation	Instant	Progressive
Brick Requirements	12 total	40 total (4x tier-3)
Visual Progression	Static ring	Animated building
Gameplay Pace	Faster	More gradual
Strategic Depth	Moderate	High
Polish Level	Basic	Enhanced

Future Enhancements

• Particle effects for brick collection
• Station convergence animation
• Different brick types/rarities
• Sphere energy production bonus
• Victory screen on completion
• Sphere rotation animation
