Assert

Description

Assert 类包含用于在代码中设置不变量的断言方法。

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.

一个断言方法的失败不会中断执行的控制流程。 失败时，系统会将断言消息记录在日志中 (LogType.Assert)，而执行 会继续进行。如果 Assert.raiseExceptions 设置为 true，则系统会抛出 AssertionException 而不是将消息记录在日志中。

如果调试器附加到项目（System.Diagnostics.Debugger.IsAttached 为 true），则系统会抛出 AssertionException 以暂停执行并 调用调试器。

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);
    }
}
