Space Age - Space

[SWeini]

Support space travel and multiple planets

Space Map
The space map is part of the tech tree

• Reconstruct space map using SpaceLocationPrototype and SpaceConnectionPrototype
• Integrate into tech tree with UnlockSpaceLocationModifier
• Trigger technologies for CreateSpacePlatformTechnologyTrigger and SendItemToOrbitTechnologyTrigger

Space Platforms

• CreateSpacePlatformTechnologyTrigger
• SpacePlatformStarterPackPrototype
  Contains links to surface (with its properties) and initial items which might be important for milestones

Asteroids
Model asteroid collection

• Read all AsteroidChunkPrototype::minable
• Read all AsteroidCollectorPrototype that can mine asteroid chunks
  I couldn't find any category, so every collector can mine every chunk
• What is the speed of 1 collector entity?
• Support AsteroidPrototype
  • Model damage to destroy them
  • Model dying_trigger_effect with CreateAsteroidChunkEffectItem
• Each location and connection has a unique combination of asteroids and asteroid chunks
  This could be made into specific recipes that mine in the "correct" ratio.
  Asteroid collectors can be filtered, so it should still be possible to mine only a single asteroid chunk prototype.

Surface Conditions
Planets are different

• Read PlanetPrototype and their surface_properties
• Provide GUI to select a planet per sheet and/or nested table
• Entities only work with compatible EntityPrototype::surface_conditions
• Recipes only work with compatible RecipePrototype::surface_conditions
• Read PlanetPrototype::map_gen_settings to have different resources available on each planet
• Entities only work with compatible EntityPrototype::tile_buildability_rules, tile availability according to map_gen_settings
• Variable solar panel / accumulator output defined by "solar-power"/"day-night-cycle" surface properties and PlanetPrototype::solar_power_in_space

Space Travel
Model flying and asteroids along the way.

• Introduce traveled distance imaginary good
• Read ThrusterPrototype
  Consumes fuel and oxidizer
  Variable performance according to min_performance and max_performance, this would allow for fixed building count of fuel/oxidizer production, plus fixed building count for thrusters, automatically adjusting the performance. This is totally different from other forms of "fixed" things.
  Generates traveled distance.
  Does speed depend on the weight of the platform?
• Asteroid spawning
  Generate asteroids per distance according to SpaceConnectionPrototype::asteroid_spawn_definitions

Interplanetary Logistics
Model sending items to other planets.

• Attach planet information to each good
• Sending item from planet into space costs rocket launches
  Like normal rocket launches, but has to respect ItemPrototype::weight and UtilityConstants::rocket_lift_weight
• Sending items from space to planet is free
• Assume space travel is free/self-sufficient
