The Acceleration property of the CharacterController class represents the rate at which the character's velocity increases over time. This property is crucial for controlling how quickly a character can reach its maximum speed from a standstill or when changing directions.

To use the Acceleration property, simply set it to a desired value within the specified range. The range is defined by the RangeAttribute as 0 to 64, with a step of 0.01. This allows for fine-tuning of the character's acceleration behavior.

Example usage:

CharacterController characterController = new CharacterController();
characterController.Acceleration = 10.0f; // Sets the acceleration to 10 units per second squared
