# Toggles

Toggles are a way to turn on and off parts of a creature. When a toggle is off, none of its children will be active.

Calculated toggles should be avoided if possible, because while they offer a lot of power and flexibility to the creature engine, they often create [dependency loops](/docs/dependency-loops) that can be difficult to troubleshoot, causing parts of a creature to calculate incorrectly.

Calculated toggles can be applied by [actions](/docs/property/action) and will apply their children if the condition is true, but they should be avoided in favor of [conditional branches](/docs/property/branch) which can do the same, but are more efficient.
