Assert

説明

Assert クラスには、コード上に不変条件を設定するためのアサーションメソッドに含まれています。

All method calls will be conditionally included only in a development build, unless specified explicitly. See BuildOptions.ForceEnableAssertions. The inclusion of an assertion is controlled by the UNITY_ASSERTIONS define.

Assert throws exceptions by default whenever an assertion fails. You can however set Assertions.Assert._raiseExceptions to false and Unity then logs a message using LogType.Assert instead.

If a debugger is attached to the project (System.Diagnostics.Debugger.IsAttached is true), AssertionException will be thrown in order to pause the excecution and invoke the debugger.

using UnityEngine;
using UnityEngine.Assertions;

public class AssertionExampleClass : MonoBehaviour
{
    public int health;
    public GameObject go;

    void Update()
    {
        // You expect the health never to be equal to zero
        Assert.AreNotEqual(0, health);

        // The referenced GameObject should be always (in every frame) be active
        Assert.IsTrue(go.activeInHierarchy);
    }
}
