unity编辑器绘制扇形

使用

UnityEditor.Handles.DrawSolidArc

using UnityEngine;
using UnityEditor;

public class DrawSectorHandles : MonoBehaviour
{
    public float radius = 5f;  // 扇形半径
    public float angle = 90f;  // 扇形角度
    public Color arcColor = Color.red;  // 扇形颜色

    void OnDrawGizmos()
    {
        // 设置颜色
        Handles.color = arcColor;

        // 计算扇形起点和终点的方向
        Vector3 forward = transform.forward;  // 扇形的正前方向
        Vector3 fromDirection = Quaternion.Euler(0, -angle / 2, 0) * forward;  // 扇形左边界

        // 绘制实心扇形
        Handles.DrawSolidArc(transform.position, Vector3.up, fromDirection, angle, radius);
    }
}
