§3 Core Systems — Galaxy Strike Online

Resource Economy (GDD §5)

Resources

Metal — 100/hr base, 10,000 cap
Gas — 60/hr base, 5,000 cap
Crystal — 40/hr base, 5,000 cap
Energy Cells — 200/hr base, 8,000 cap
Dark Matter — 5/hr base, 500 cap

Production Formula

output = base_rate × (1 + 0.15 × level) × research_mult × sector_richness

Implementation

60-second server tick (ResourceSystem.tick())
Offline accumulation — computed on login
Resource tick on disconnect — partial credit
Building upgrades multiply rates
Research bonuses stack multiplicatively

Resource System100%

Full tick, offline, HUD display

Base & Buildings (GDD §6)

Buildings

Command Center (max lvl 20)
Mining Facility — metal rate
Gas Extractor — gas rate

Building Costs (GDD §6.2)

All buildings require a blend of credits + metal/gas/crystal. Example:

Shipyard — 500cr + 1000 metal + 300 gas
Research Lab — 300cr + 600 metal + 100 crystal
Hangar Bay — 500cr + 1500 metal + 400 gas
