Cosmic Radiation

While we wait to see what Keen cooks up for 1.207, this cosmic radiation system for Space Engineers integrates seamlessly with Eat.Sleep.Drink.Repeat! (EDSR) and Eat.Sleep.Drink.Repeat.Advanced! (EDSRA).

With the exception of player production of Anti-Radiation injections, it also works in Vanilla.

Add it in to my Proper Solar System world!

Cosmic Radiation tracks your exposure (“Rads”) when you leave protected zones—atmospheres, gravity fields, or pressurized volumes. Accumulate too many Rads and you’ll start suffering health damage. Use shielding, habitat design, or medical treatments to survive in harsh space environments.

• Dynamic radiation accumulation based on:
  
  • Gravitational and magnetic field strength
    
  • Atmospheric presence and density
    
  • Depth underground (regolith shielding)
    
  • Line-of-sight exposure to stars (in a possible future update)
• Health damage kicks in slowly after 80 Rads, grows increasingly lethal without treatment
  
• Multiple mitigation methods: cockpit pressurization, airtight bases, gravity generators, and planetary shelter
  
• Medical treatments:
  • Standard Medical Kits (−5 Rads in 5 sec)
    
  • Radiation Exposure Kits (-15 Rads in 15 sec)
    
  • Anti-Radiation Injections (easily produced, but toxic. -3 Rad in 3 sec, but also -3 Health)
    
  • Natural healing when sleeping in pressurized environments
    
  • Constant healing in an Earth-like environment
  All of the consumable medical treatments can show up in Unknown Signal pods.

• [NEW] Stellar Radiation - The sun is a deadly lazer. Real Solar Systems/Real Stars compatible!
  
• Damaged reactors leak radiation!
  Off by default. Toggle with /crreactor.
  
• Damaged reactors can also leak heat from nuclear fuel decay!
  Off by default. Toggle with /crheat.

Reactor radiation and heat both increase by fuel load and reactor damage, but decrease by range and atmospheric pressure. Both are blocked when seated inside a sealed, pressurized cockpit block. Both are independent of one another. They are turned off by default because they are essentially feature creep and I don't want to force them on unsuspecting people who subbed before they were added.

If you don't see the new options in your pre-existing save game config file, delete the existing file, load the world, save and exit. You should then be able to access the new options.

1. HUD Compatibility mod.
   Either Standard HUD or Modern and Fancy (Color) HUD, but not BOTH.
   Required if using EDSR or EDSRA. Without one, this mod will still function, but you will not see your radiation level, since those mods will overwrite the default HUD included in this mod.
   
2. EDSR or EDSRA, but not BOTH.
   
3. Cosmic Radiation (This mod)

Mod order in vanilla does not matter, except that any non-compatible HUD mod will override the default if it is higher in the mod load order. No HUD mod is required for Vanilla unless you prefer the "modern" version, and then you will need to grab the compatibility mod above in order to see your radiation level, and then go pay Adriano some love for creating such a great HUD mod.

• Pressurized single block cockpits grant baseline shielding.
  
• Stay inside airtight structures for extra protection.
  
• Spin up gravity generators to create artificial magnetic fields to block cosmic rays.
  
• Put 10m+ of rock over your head to fully block cosmic rays if you can't build a pressurized structure yet. This works for asteroids, too!
  
• Monitor your Rads on the HUD—treat exposure promptly to avoid rapid health loss.
  
• Sleeping in a pressurized environment will slowly but naturally reduce your radiation levels.
  
• Your radiation levels will naturally decay while you are on the surface of a fully Earthlike planet. The gravity and atmosphere of other worlds will also help, to varying degrees.

• Fold in anything useful from 1.207
  
• Radiation fields/belts for Real Gas Giants?
  
• Faster radiation healing in Medical Stations
  
• Configurable parameters for custom game modes
  
• Split reactor radiation and heat into range of effect and line of sight components?
  
• Spread shelter check raycasting workload over the span of the 100 ticks in between main loop cycles for performance?
  
• Spread radiation and health damage between cycles as well, so that the HUD bar updates are more fluid?

Radioactive Reactor Smoke by Chipstix213. Basic idea, no code or assets used. Mine is just brute force simple and doesn't change the particle effects like his does. His is likely much more efficient. I just wanted an option that used the same radiation mechanic used in CR.
