This mod locks your view to a specific direction and can be adjusted to only lock up and down or left and right. The view can also be locked to the closest x and y axes using a key.

Usage:

Align your view to whichever x and y axis you would like and press Y. This will lock your view to those axes. To unlock/lock your up and down movement, press U. To unlock/lock your left and right movement, press I. Alternatively, just press U or I to unlock/lock your left and right or up and down movement.

Examples:

When using an afk farm, sometimes keeping the view steady and consistent can be difficult, especially when having to place blocks. This mod fixes that problem by allowing the user to configure their view to specific positions.
Repetitively placing down blocks can be quite tedious. Sometimes when placing long lines of blocks, the player will start to drift from side to side, requiring you to realign yourself. This mod allows you to align yourself to a specific axis so you don't have to deal with realignment.

Controls:

Y: Toggle locks the view to the closest x and y axes

U: Toggles locking on up and down view movement (x axis)

I: Toggles locking on left and right view movement (y axis)
