To use the LookAt() method for aiming, follow these steps:

1. Import your character to Unity and place it on the Scene.
2. Follow the previous recipe to make a character walk and aim.
3. Attach the CharacterLookAt.cs script to the character.
4. Create a new Sphere object and name it AimTarget.
5. Assign the chest bone to the CharacterLookAt.cs component's Bone field.
6. Assign the AimTarget to the Target field of the CharacterLookAt.cs component.
7. Make the AimTarget a child of the Main Camera game object. We are using the same CameraLook.cs script in this recipe. You can find the script in the Shared Scripts folder in the example Unity project provided.
8. Offset the AimTarget position in its local Z axis around 20 units.
9. Play the game to see the effect. Our character will try to aim at the AimTarget. You may need to adjust the Additional Rotation vector in the CharacterLookAt.cs component. In our example, it is set to 15 in X and 20 in Y.
