### energy_source :: Read LuaElectricEnergySourcePrototype

The energy source prototype for the equipment.

### equipment_categories :: Read array[string]

Category names for this equipment. These categories will be used to determine whether this equipment is allowed in a particular equipment grid.

### burner_prototype :: Read LuaBurnerPrototype?

The burner energy source prototype this equipment uses, if any.

### electric_energy_source_prototype :: Read LuaElectricEnergySourcePrototype?

The electric energy source prototype this equipment uses, if any.

### background_color :: Read Color

The background color of this equipment prototype.

### attack_parameters :: Read AttackParameters?

The equipment attack parameters.

Can only be used if this is ActiveDefenseEquipment

### automatic :: Read boolean

Whether this active defense equipment is automatic. Returns false if not active defense equipment.

### valid :: Read boolean

Is this object valid? This Lua object holds a reference to an object within the game engine. It is possible that the game-engine object is removed whilst a mod still holds the corresponding Lua object. If that happens, the object becomes invalid, i.e. this attribute will be `false`. Mods are advised to check for object validity if any change to the game state might have occurred between the creation of the Lua object and its access.

### object_name :: Read string

The class name of this object. Available even when `valid` is false. For LuaStruct objects it may also be suffixed with a dotted path to a member of the struct.
