Damage Mechanics

In Survival Mode, every block has hitpoints that represent its physical integrity, and players have hitpoints that represent their health.

In singleplayer, or if you are the server admin, you can enable or disable individual Damage Mechanics in the World Settings on a per game basis.

Damage level	Players	Blocks
Full hitpoints	The players are healthy	A functional block is fully functional, an armor block is intact.
Loss of hitpoints	Collisions, explosions, exposure, or weapons have subtracted hitpoints and the players are wounded. They can still act normally. They can heal themselves using Life Support.	Collisions, explosions, or weapons have caused damage to blocks. Damaged above "the functional line", they still function. Blocks damaged below "the functional line" stop providing their functionality. Damaged armor blocks deform and allow damage to neighbouring blocks; dropped components turn into Scrap Metal. Damaged blocks can still be repaired.
Zero hitpoints	Dead players drop their backpack and respawn at an allied Medical Room or Survival kit.	If a block's hitpoints reach zero, the block breaks beyond repair. Its components turn into Scrap Metal. It stops providing its functionality; attached neighbouring blocks start coming loose.

Voxel Damage

Voxels can be destroyed by explosions (such as warheads, rockets, and explosives), by meteors, by collisions or the impact of crashed ships, and by drills.

Tip: Depending on graphic settings, voxel changes on planet surfaces can be seen from orbit which can give away a player’s position in multiplayer.

To a certain degree you can “repair” smaller holes using Voxel Hands. But too much voxel deformation will eventually slow down performance. To really reset voxel deformations, use the Admin Screen.

Collision/Impact Damage

The HUD shows a block's state when you point at it holding a grinder or welder. This block is damaged "below the functional line".

Collisions and impacts are equally devastating to ships, rovers, voxels, and player characters.

Examples of what counts as collision for ships and rovers (grids):

• Hitting voxels (mountains, asteroids, ice lakes, boulders) or grids when flying a ship or when catching air in a rover
• Free-falling from a height
• Being hit by flying block debris
• Intersecting with suddenly spawning loose Ores after a filled container bursts

When Hydrogen and Oxygen Tanks are damaged (or grinded) below the functional line, they leak fuel and eventually explode.

Examples for sources of collision damage for player characters:

• Hitting voxels (planet surface, boulders, ice lakes, asteroids) or grids when jetpacking
• Free-falling from a height with disabled jetpack
• Bumping into blocks or other players when not seated in a moving vehicle, e.g. due to abrupt rover/ship manoeuvres
• Being crushed by falling block debris, e.g. while salvaging wrecks in gravity
• Being hit by loose Ores, especially in tight mining tunnels

Colliding with trees and bushes doesn’t do much damage, but trees slow vehicles down and can make vehicles rebound into neighbouring voxels.

Explosive Damage

Explosions affect grids, voxels, and player characters.

Short version: Don't store all ammo in one cargo container, distribute it using Sorters. Also, don't store oxygen and hydrogen tanks near essential parts of the ship.

• Any block that contains explosives or ammunition in its inventory will explode when destroyed by taking damage. The explosion radius is based on the amount and type of munitions that were inside the inventory.
• Destroyed Hydrogen and Oxygen Tanks explode and deal damage based on the amount of fuel left inside at the time of their destruction.
• Dropped Explosives detonated with weapon shots deal damage to blocks in a (1cm*number of explosives in stack) blast radius. Blocks get damaged proportionally to their distance to the explosion.
• Rockets have a 4m blast radius on impact, doing damage to blocks proportionally to their distance from the center of the blast.
• Warheads explode when shot, or after a countdown, or after manual detonation. Large-grid warhead have a 22.4415m (4.4883m for small-grid warhead) explosion radius even against voxels.
• The max explosion range is ~170m.

Projectile Weapons

Block Weapons damage players and blocks, but not voxels. Artillery Shells and Assault Cannon Shells can ricochet against grids at certain angles.

Block Armor

Welded and unwelded blocks have the same mass, welding them adds durability in the form of hitpoints. Each block's health is equal to the sum of the health of its components, meaning that more expensive und undamaged blocks also have higher durability:

Name	Mass(kg)	Integrity	Integrity/Mass Ratio
Construction Component	8	30	3.75
Metal Grid	6	15	2.5
Interior Plate	3	15	5
