Changelog

Fires

• Added fires. A fire is a group of cells that take damage over time. Cells below the waterline are extinguished
• Fire damage taken reduces the armor value of blocks, to a minimum of 1. X% total health taken as fire damage = (1-X)% armor left
• Fires spread when they destroy blocks, or if they have lots of fuel relative to their size
• Fires have 3 properties: fuel, intensity and oxidizer
• Fuel determines how much total damage a fire can do. The baseline is 1 fuel = 1 damage
• Intensity determines how much fuel/s a fire uses for every burning cell, and reduces the damage reduction of fire resistant materials. Fuel used/sec/burning cell is 1.5 * INTENSITY
• Oxidizer doubles the armor reduction effect of fires (50% fire damage taken reduces every block to 1 armor), and makes it possible for them to burn under water
• At 20 intensity 1 oxidizer is used for every 4 fuel over water, 1 oxidizer for every 2 fuel below water. Every 10 intensity increase also increases oxidizer use by 1/3 of the base
• Blocks have 2 new properties: fire resistance and flammability
• A fire with intensity below the block's fire resistance does reduced damage to that block. Damage multiplier: (INTENSITY - RESISTANCE * 0.15) / (RESISTANCE * 0.85), 0-1 range.
• Blocks with flammability above 0 add fuel to the fire for every unit of fuel used. Intensity of the fuel added is the block's fire resistance
• Wood has 10 resist and 80% flammability, 1 cell taking damage from a 100 fuel, 50 intensity fire: 25+60=85 fuel left, new total intensity is ~21.76
• Blocks generally have 10-60 fire resist, and 0-80% flammability
• High speed fans the flames, increasing fire damage done/fuel
• Big fires choke themselves out, reducing damage done/fuel. Reduction starts at 5000 total burning cells on a vehicle, minimum efficiency is 30% of the original.
• Added incendiary bodies to APS and missiles and incendiary pellets to CRAM. Their intensity range is 20-40, and they can also pack oxidizer
• APS and missile impacts ignite a fire around the explosion point
• Fires have an IR signature, a function of total fuel and intensity. IR guidance and AI hot point targeting can target individual fires
• A burning block colliding with another construct spreads the fire to it
• Added a tab to the V menu showing all the active fires on that vehicle/structure
• Added a designer-only character item for igniting fires
• Destroying fuel tanks ignites fires, fuel of the fire depends on the fuel level of the vehicle. Intensity is 20
• Destroying steam boilers and controllers creates fires, and weaker explosions. Intensity is 20, fuel is a function of the steam in the boiler chain

Flamers

• New weapon system: flamers
• Flamers use fuel, and ignite fires at short range. Cheap and compact for the firepower
• Flame speed is ~300 m/s, maximum range is ~400m
• 2 main block variants, both 1x1x4m beams: connection point in the back with +-35° azi and elevation range, connection point at the bottom with 360° azi and -10° to 89° elevation range
• Pipes connect the main blocks to tanks
• 3 tank types: fuel, oxidizer and catalyst. They increase fuel/oxidizer throughput and intensity
• Intensity without catalyst tanks is 20. 2:1 fuel:catalyst tank ratio is 30 intensity, 1:2 is 50, ...
• 2 tank sizes: 1x1x1 and 1x3x3. Smaller tanks are more compact and more expensive for the firepower
• Tanks can be chained, they can only connect to tanks of the same size and type
• Destroying flamer tanks ignites fires
• Tank lines have to be pressurized by adding compressors to their end
• Compressors use power, and have a variable power use
• Flamer pressure is the weighted average of the pressure of individual tank lines. Lower pressure means slightly lower range

Lasers

• Lasers have intensity instead of AP, and they are mitigated by fire resistance instead of armor. Damage multiplier is RESIST / INTENSITY, capped at 1
• Lasers ignite fires when they destroy blocks. Fuel of the fire is determined by flammability of the blocks destroyed, intensity by fire resistance
• Laser base damage is reduced to 50%, and smoke/shield reduction is much weaker
• Laser damage counts as fire damage, also reduces armor of the blocks damaged
• Laser fires don't add any oxidizer
• New laser component: superheating modulator. Can be placed on combiners, reduces base damage to a minimum of 75% and increases fuel of fires ignited to a maximum of 250%
• Short range combiner ranges from 100-500 to 150-600

Misc

• Wood base health up from 180 to 200
• Impact damage gets the same boost as explosions under water
• Local weapon controllers now have an alternate mode, they can control weapons up to 4 cells away in 2 directions
• Steam pipe durability increased
• Propeller hub overlay is only displayed in build mode
• Increased particle cannon damage output by ~4.2%
• Added target prioritisation options for plasma and flamer firepower
• APS projectiles have 20% more health
• APS flak damage reduced by ~11%
• APS flak warhead renamed to munition defense warhead, flak damage to anti-munition damage
• Missile interceptors do 20% reduced damage to projectiles under water
• Maximum turbocharger power/fuel bonus up by ~11%
• Limited maximum ring shield destruction energy to EFFECTIVE_AREA * 3000 (intensity is unchanged, 6)
