Cosmic Additions – Oxygen & Survival Addon

Cosmic Additions expands the vast universe of Cosmic Horizons by adding realistic survival challenges to space exploration. Designed for players who love the thrill of interplanetary travel, this addon brings depth to your adventures with three core mechanics: oxygen supply, radiation exposure, and extreme temperatures. Craft and upgrade space suits to withstand the harsh environments of planets, moons, and galaxies, turning every expedition into a test of strategy and preparation.

## Key Features

• Oxygen Management: Equip suits to monitor and consume oxygen levels. Run low, and you'll see bubble effects as your air supply depletes—find an Oxygen Distributor or risk suffocation!
• Radiation Resistance: In high-radiation zones like Mercury or Pluto, exposure builds over time. Suits reduce accumulation rates, but exceeding your threshold triggers the radiation effect, causing damage and debuffs like nausea and slowness.
• Build in Sealed Areas: Establish your own protected bases in designated Sealed Areas — safe from environmental hazards and hostile mobs, perfect for storing your resources and crafting equipment.

• Temperature Regulation: Each planet has a fixed temperature (inspired by NASA data, scaled for gameplay). Suits provide safe ranges—Steel handles Mars (-65°C) and Luna (+120°C), Titanium opens most of the solar system, and Nickel is essential for extremes like Venus (+460°C) or Pluto (-225°C). Stray outside your suit's limits, and suffer burning or freezing effects.
• Customizable Suits: Four tiers of suits (Improvised, Steel, Titanium, Nickel) with increasing protection. Mix and match pieces for partial coverage, but missing parts reduce effectiveness.
• HUD Integration: A clean overlay shows real-time oxygen bars, radiation levels, and a dynamic thermometer for temperature, making monitoring intuitive.

## How to Get Started ## Installation: Cosmic Additions is an addon for Cosmic Horizons, so install Cosmic Horizons first from Modrinth or CurseForge. Add Cosmic Additions to your mods folder. Requires Minecraft 1. 20. 1 with Forge loader. No additional dependencies, but compatible with JEI for recipes.

Crafting Suits: Start with basic materials (Steel for tier 1, titanium for Tier 2). Use an anvil or crafting table to assemble helmets, chestplates, leggings, and boots.

Exploration Tips:

1. Tier 1 (Steel): Perfect for Mars, Luna, and space travel (-80°C to +120°C safe range). 1. Tier 2 (Titanium): Handles Jupiter, Europa, and Mercury (-150°C to +300°C). 1. Tier 3 (Nickel): Endgame gear for Venus, Neptune, Uranus, and Pluto (-250°C to +500°C).

## Survival Guide: ## !(https://cdn.modrinth.com/data/cached_images/fe1b46e6d6db91459bd9ad288214c8fcc54f3144.png) HUD Overview: Your heads-up display (HUD) is your lifeline. It shows:

• Oxygen Bar: A segmented bar (0-10 levels) indicating oxygen levels (0-100%). Bubbles decrease as oxygen depletes.
• Radiation Bar: A segmented bar showing exposure (0-60 units). Fills faster in high-radiation planets like Mercury or Pluto.
• Temperature Bar: A thermometer with a moving line indicating current temperature (°C). 0°C is neutral (center). Blue for cold, red for hot.

## Oxygen Management

How it Works: Oxygen is consumed in hostile dimensions (e.g., space, moons, planets) at a rate based on your suit tier and activity. The variable OxygenLevel starts at 100% and decreases over time. When it reaches 0%, bubble effects appear, and you take damage (delegated to DecreaseProcedure).

Consumption Rate (per second):

No Suit: 2. 0 (rapid depletion). Improvised/Steel (Tier 1): 0. 5 (moderate, good for short trips). Titanium (Tier 2): 0. 25 (slow, for longer explorations). Nickel (Tier 3): 0. 1 (minimal, endgame).

Missing suit pieces increase consumption by 0. 2 per piece.

Tips: Monitor the oxygen bar—bubbles mean you're low. Use oxygen tanks for quick escapes; they pause consumption. Experiment with partial suits, but full sets are essential for deep space.

## Radiation Resistance

How it Works: Radiation accumulates in specific planets (e.g. Mercury, Pluto) as RadiationExposure (0-60 units). It increases at a rate based on your suit:

No Suit/Improvised: +4/s (reaches 60 in 15s). Steel (Tier 1): +2/s (reaches 60 in 30s). Titanium (Tier 2): +1/s (reaches 60 in 60s). Nickel (Tier 3): +0/s (inmune). When _RadiationExposure_ reaches the threshold (15 for no suit, 30 for Steel, 60 for Titanium), it triggers the radiation effect, causing damage (1 HP/s), nausea, slowness, and accelerated oxygen consumption (if below 50%).

Tips: The radiation bar fills progressively. Use Titanium for medium-risk planets, Nickel for high-radiation ones. Partial suits increase exposure rate.
