14. Wrapping up

• In this section, we will cover weapon holding and audio.

Weapon

• Here are two main methods to make the player character hold a weapon.

Basic method

• If your character's arms are already in a weapon-holding position, attach the weapon 3D model to the character's primary hand.
  • Locate the main hand in the character skeleton in the scene hierarchy: Hips > Spine > RightShoulder > RightArm > RightForeArm > RightHand.
  • Place the weapon 3D model as a child of the RightHand and position/rotate it accordingly.

IK method

• Attach a weapon using a two-bone IK (Inverse Kinematics) constraint.

Audio

• Add the "Audio Source" component to the weapon (which we want to produce the shooting sound).
  • Attach the appropriate audio clip to the "AudioClip" field.
  • Disable the "Play On Awake" field.
• In the Shooting.cs script:
  • Declare public AudioSource shootAudioSource;
    • Set that variable from the inspector to the audio source on the weapon.
  • Add shootAudioSource.Play(); inside the Shoot() method.
