Parameters

typeThe type of component to retrieve.
componentThe output argument that will contain the component or null.

Returns

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

Description

using UnityEngine;

public class TryGetComponentExample : MonoBehaviour { void Start() { if (gameObject.TryGetComponent(typeof(HingeJoint), out Component component)) { component.name = "My Hinge"; } } }

public bool TryGetComponent(out T component);

Returns

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

Description

Generic version. See the Generic Functions page for more details.

using UnityEngine;

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