# Boundary Enforcer

BattleArena comes pre-installed with a boundary enforcer module which ensures that players do not leave the bounds of an arena.

### Configuring the Module

This module can be enabled by adding **boundary-enforcer** to the **modules** section of your [Arena Configuration](https://docs.bplug.in/books/user-guide/page/arena-configuration). No other configuration is required from this point, and once BattleArena has been reloaded with **/battlearena reload**, players will be unable to leave the arena boundaries configured in the [Map Creation](https://docs.bplug.in/books/user-guide/page/map-creation) process.
