GameObject.TryGetComponent

パラメーター

戻り値

bool Returns true if the component is found, false otherwise.

説明

Gets the component of the specified type, if it exists.

TryGetComponent will attempt 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 (gameObject.TryGetComponent(typeof(HingeJoint), out Component component))
        {
            component.name = "My Hinge";
        }
    }
}
