What setting in the Input Manager should be adjusted to stop unintended character movement when the gamepad is not in use?

Adjusting the 'Dead' setting in the Input Manager is crucial for preventing unintended character movement when a gamepad is not in use. The 'Dead' zone defines a range of input around the center of the joystick where any movement is ignored. By increasing this range, you ensure that small, unintentional movements of the joystick—such as those that may occur due to slight touches or neural noise—do not result in character movement in the game. This is particularly important in scenarios where precise control is needed, as it allows players to rest their hands on the gamepad without accidentally steering their character.

If the 'Dead' zone is set too small, even minor deviations in the joystick position could be interpreted as intentional input, leading to frustrating character movement when players are not actively controlling their character. Thus, increasing the 'Dead' zone helps enhance the overall gameplay experience by ensuring that character movement is only registered when the player deliberately moves the joystick.
