title: Spawner Controller
---

The Spawner Controller controls the automated mob spawning system. When placed 
above a [spawner cage](@oritech:spawner_cage_block), it can be used to spawn specific mob types.

<Callout variant="warning">
    *Oritech Inc* accepts no liability for existential crises experienced by mobs questioning their 
    purpose in life, nor for any ethical concerns you may develop about industrialized soul harvesting.
</Callout>

## Setup

The mob type is determined by the first entity that walks over the controller. This 
type can only be changed by breaking and replacing the controller. Once a mob type 
is set, the controller will highlight the required size of the spawner cage needed 
underneath it.

## Operation

The controller collects souls from nearby deaths and consumes them to spawn the 
assigned mob. 

- **Soul Cost**: The number of souls required for one spawn is calculated based on 
the mob's health (specifically the square root of its maximum HP).
- **Spawn Range**: The controller attempts to find a valid spawning surface within 
a small radius (4 blocks) around itself.
- **Redstone Control**: Applying a redstone signal to the controller will disable 
it, stopping all spawning operations.

Right-clicking the controller provides information on its current operational state, 
including the set mob and current soul levels.

    The spawner cannot be set to mob types that are part of the `oritech:spawner_blacklist` tag.
