Assert

描述

Assert 类包含用于在代码中设置不变量的断言方法。

所有方法调用均将按条件仅包含在开发 版中，除非明确指定（请参阅 BuildOptions.ForceEnableAssertions）。 断言的包含由 UNITY_ASSERTIONS 定义控制。

A failure of an assertion method does not break the control flow of the execution. On a failure, an assertion message is logged (LogType.Assert) and the execution continues. If Assert.raiseExceptions is set to true, an AssertionException is thrown instead of logging a message.

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.

For shorter and more readable syntax see Assertions.Must.MustExtensions.

using UnityEngine;
using UnityEngine.Assertions;

public class ExampleClass : 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);
    }
}

For different assertions syntax see Assertions.Must.MustExtensions.
