Aside from standard qualities like damage and weight, items, objects, and creatures can have physical or metaphysical properties that affect how they behave and how other items interact with them.

Metal

Metal items can rust, be magnetized, and be pulled by Pulsed field magnet.pngpulsed field magnets. Creatures can be metallic as well. This means their entire body becomes pulled if magnetic pulsed, and will refuse to properly function if rusted. Metal items (but not creatures) cannot be set on fire.[1]

For modding purposes, this property corresponds to the Metal object part.

Organic

A thing that is organic[2]:

Cannot be removed once equipped

Items with this property can't be unequipped normally by the player, but can be unequipped under other circumstances by the game, such as when they're destroyed.

For modding purposes, this property corresponds to the Cursed, CursedCybernetics, and NaturalEquipment object parts.

EMP Sensitive

This item will deactivate if hit by an EMP blast, usually from Electromagnetic Pulse or an EMP grenade.

For modding purposes, this property usually corresponds to having an IsEMPSensitive attribute of true on an appropriate object part. There are several such parts; refer to ObjectBlueprints.xml for examples. There is a generic base class that supports parts with involved conditional behavior, called IActivePart; see Modding:Active Parts for details. IsEMPSensitiveis a field on that class.

Some parts implement hardcoded EMP sensitivity because they do not use IActivePart. These include support parts for geomagnetic discs, night vision implants, mines, bombs, high-powered magnets, melee weapon elemental damage, walltraps, and conveyor belts.[7]

Reality Distortion Based

Capabilities that are reality distortion based are subject to being interfered with by normality.

On items, this property usually corresponds to having an IsRealityDistortionBased attribute of true on an appropriate object part. This is another configuration point provided by IActivePart; see Modding:Active Parts for details.

Some mutation parts can also be configured for this property, using fields called either IsRealityDistortionBased or RealityDistortionBased. There is no way to change these fields via Mutations.xml, so this is only manipulable by scripting mods.

Occluding

Occluding objects are objects that block a character's field of view. Objects that are occluding also block non-seeping gases from passing through their tile. In terms of AI, even though the enemy knows their target is behind an occluding object, and the object does not block bullets, they will still refuse to fire until they are able to see their target again. Occluding items can also prevent NPCs from witnessing the player stealing an object. The most common class of objects that occlude light are walls (including closed doors and vents). Other occluding objects are shown below.[8]
