## Controls
Eagler Mobile provides a variety of mobile controls and gestures to navigate the EaglerCraft client. While many controls mimic Minecraft Pocket Edition's controls, other controls have been added to interact with Minecraft Java Edition features.

> [!WARNING]
> Because Eagler Mobile does not directly inject code into the EaglerCraft client, Eagler Mobile's touch controls only work for the standard control scheme that the EaglerCraft client is set to start with. Editing the controls in the EaglerCraft client could create unintended behavior.
