请问unity game窗口如何可视化物体方向角范围，请给出代码实现

可以使用Unity中的Gizmos来可视化物体方向角范围。具体实现代码如下：

using UnityEngine;

public class VisualizeDirection : MonoBehaviour
{
    public float angle = 45f;
    public float distance = 10f;

    private void OnDrawGizmosSelected()
    {
        Gizmos.color = Color.yellow;
        Gizmos.DrawWireSphere(transform.position, distance);

        Vector3 rightDirection = Quaternion.Euler(0, angle, 0) * transform.forward;
        Vector3 leftDirection = Quaternion.Euler(0, -angle, 0) * transform.forward;

        Gizmos.color = Color.green;
        Gizmos.DrawLine(transform.position, transform.position + rightDirection * distance);
        Gizmos.DrawLine(transform.position, transform.position + leftDirection * distance);
    }
}

在Unity中将该脚本挂载到需要可视化方向角范围的物体上，即可在Scene视图中看到可视化效果。
