Component.TryGetComponent

参数

返回

bool 如果发现组件，则返回 /true/，否则返回 /false/。

描述

获取指定类型的组件（如果存在）。

TryGetComponent attempts to retrieve the component of the given type. The notable difference compared to GameObject.GetComponent is that this method does not allocate in the Editor when the requested component does not exist.

using UnityEngine;

public class TryGetComponentExample : MonoBehaviour
{
    void Start()
    {
        if (TryGetComponent<HingeJoint>(out HingeJoint hinge))
        {
            hinge.useSpring = false;
        }
    }
}

参数

返回

bool 如果发现组件，则返回 /true/，否则返回 /false/。

描述

The non-generic version of this method.

This version of TryGetComponent is not as efficient as the Generic version (above), so you should only use it if necessary.
