BaseNetInput

Base class for Input nodes used with rollback.

During rollback, multiple logical ticks are simulated in the span of a single network tick. Since these are just logical ticks, no actual input arrives during them from the input devices.

The solution is to gather input before the tick loop, and use that input for any new ticks simulated during the rollback.

Gathering input

This class provides a virtual _gather method that you can override. Set the variables configured in RollbackSynchronizer in your own implementation:

extends BaseNetInput

var movement: Vector3 = Vector3.ZERO

func _gather():
  movement = Vector3(
    Input.get_axis("move_west", "move_east"),
    0,
    Input.get_axis("move_north", "move_south")
  )
