Question

我的目标是让NPC关注ThePlayer。我有一个功能正常的NPCFollower脚本附加到一个角色，有两个动画，空闲和步行。我想知道是否有人知道我如何使用'SimpleCharacterControl'script实现NPCFollower脚本，该脚本附加到带有多个动画的动画师的角色。我想呼吁两个动画，走路和闲置。我非常感谢你的帮助！

NPCFollow'脚本

public class NPCFollow : MonoBehaviour {

public GameObject ThePlayer;
public float TargetDistance;
public float AllowedDistance = 5;
public GameObject TheNPC;
public float FollowSpeed;
public RaycastHit Shot;


void Update () {
    transform.LookAt(ThePlayer.transform);
    if (Physics.Raycast(transform.position,transform.TransformDirection(Vector3.forward),out Shot))
    {
        TargetDistance = Shot.distance;
        if(TargetDistance >= AllowedDistance)
        {
            FollowSpeed = 0.02f;
            TheNPC.GetComponent<Animation>().Play("Walk");
        }



        else
        {
            FollowSpeed = 0;
            TheNPC.GetComponent<Animation>().Play("Idle");
        }
    }       
}

}

Answer 1

1）获取对ThePlayer的引用（您希望其他对象遵循的任何对象）。 2）找到ThePlayer的方向。 3）在DistanceFromTarget的更新检查中

if (DistanceFromTarget <= distanceUwant)
{
  setMovingSpeed=0;
  playIdelAnimation();
}
else 
{
  setMovingSpeed= asmuchyouwant;
  playWalkAnimation();
}
