Sequencer command: Set AICharacterControl target

[Tony Li]

If you use Unity's Standard Assets Third Person Character with the AICharacterControl script, you can add the script below to your project. It adds the following sequencer command:

AISetTarget(target, [subject])

where:

• target: GameObject that the character should walk to, or 'none' to stop.
• subject: The character with the AICharacterControl script. Defaults to the speaker.

using UnityEngine;

    // Adds sequencer command AISetTarget(target, [subject])
    //

    // - subject defaults to speaker.
    public class SequencerCommandAISetTarget : SequencerCommand

            var target = noTarget ? null : GetSubject(0, listener);
            var subject = GetSubject(1, speaker);
            var ai = (subject != null) ? subject.GetComponent<UnityStandardAssets.Characters.ThirdPerson.AICharacterControl>() : null;
