Component.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 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;
        }
    }
}

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

説明

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.
