GameObject.GetComponent

Parameters

Description

Возвращает компонент типа type, если он прикреплен к игровому объекту и null, если не прикреплен.

Using gameObject.GetComponent will return the first component that is found and the order is undefined. If you expect there to be more than one component of the same type, use gameObject.GetComponents instead, and cycle through the returned components testing for some unique property.

using UnityEngine;

public class GetComponentExample : MonoBehaviour
{
    void Start()
    {
        HingeJoint hinge = gameObject.GetComponent(typeof(HingeJoint)) as HingeJoint;

        if (hinge != null)
            hinge.useSpring = false;
    }
}

Description

Generic version of this method.

using UnityEngine;

public class GetComponentGenericExample : MonoBehaviour
{
    void Start()
    {
        HingeJoint hinge = gameObject.GetComponent<HingeJoint>();

        if (hinge != null)
            hinge.useSpring = false;
    }
}

Parameters

Description

Возвращает компонент типа type, если он прикреплен к игровому объекту и null, если не прикреплен.

It is better to use GetComponent with a Type instead of a string for performance reasons. Sometimes you might not be able to get to the type however, for example when trying to access a C# script from Javascript. In that case you can simply access the component by name instead of type.

using UnityEngine;

public class GetComponentNonPerformantExample : MonoBehaviour
{
    void Start()
    {
        HingeJoint hinge = gameObject.GetComponent("HingeJoint") as HingeJoint;

        if (hinge != null)
            hinge.useSpring = false;
    }
}
