The GroundAngle property of the CharacterController class represents the maximum angle of the ground that the character can walk on. This property is crucial for determining the character's ability to traverse sloped surfaces within the game environment.

To use the GroundAngle property, you can get or set its value to control the maximum slope angle the character can walk on. The value is a float and should be within the range of 0 to 90 degrees, as specified by the RangeAttribute.

Example usage:

CharacterController characterController = new CharacterController();
characterController.GroundAngle = 45.0f; // Set the maximum walkable slope angle to 45 degrees
float currentGroundAngle = characterController.GroundAngle; // Retrieve the current ground angle
