Description

该盒体的总大小。这始终是 extents 的两倍。

size.x is the width, size.y is the height and size.z is the depth of the box. Note that size is given in world size. A Bound surrounding a tall human might have size.y approximately 2.0f, meaning a 2 meter height body.

//This script outputs the size of the Collider bounds to the console

using UnityEngine;

public class Example : MonoBehaviour
{
    Collider m_Collider;
    Vector3 m_Size;

    void Start()
    {
        //Fetch the Collider from the GameObject
        m_Collider = GetComponent<Collider>();

        //Fetch the size of the Collider volume
        m_Size = m_Collider.bounds.size;

        //Output to the console the size of the Collider volume
        Debug.Log("Collider Size : " + m_Size);
    }
