【问题背景】

Unity3D中开发物体的移动，实现代码如下：

public class TargetController : MonoBehaviour
{
	private CharacterController character;
	private float speedRate = 4f;

    private void Start()
    {
        character = GetComponent<CharacterController>();
        
    }

    private void Update()
    {
        float hor = Input.GetAxis("Horizontal");
        float ver = Input.GetAxis("Vertical");
        Debug.Log("hor:" + hor + ", ver:" + ver);
        Vector3 speed = new Vector3(hor, 0, ver) * speedRate;
        character.SimpleMove(speed);
    }
}

结果运行时报错信息为：

CharacterController.Move called on inactive controller

UnityEngine.CharacterController.SimpleMove (UnityEngine.Vector3)

也有其他人反馈类似问题：

【问题原因】

请看上面截图的红色报警提示部分：Step Offset must be less or equal to <scaled Height> ...

这个提示指的是 Character对象的Step Offset设置太大了，

所以是Step Offset的原因，不用在inactive controller上寻找原因

【问题解决】

将Step Offset设置为0.1
