调用了OnTriggerEnter，但从未设置变量 [英] OnTriggerEnter called but variable is never set

问题描述

我已经开始使用C#慢慢学习Unity，到目前为止，这是一个爆炸！

I've started learning Unity slowly using C# and it's been a blast thus far!

我遇到了一个小问题(我希望这是一个小问题)并陷入困境，从那以后一直在质疑我的理智.

I've run into a small problem (I hope it's a small problem) and gotten stuck, and have been somewhat questioning my sanity ever since.

在我首先运行的主脚本中，我有运行时生成原始图元(球体)并将其附加脚本的代码，脚本会检查该球体是否已触发.

In my main script which runs first I have code that generates a primitive (sphere) on the fly and attaches a script to it, the scrip checks to see if the sphere has been triggered.

主脚本

bool createNav (Vector3 _start) {

        GameObject nav = GameObject.CreatePrimitive(PrimitiveType.Sphere);
        nav.AddComponent<NavTrigger>();

        nav.collider.isTrigger = true;

        nav.transform.localScale = new Vector3(1f,1f,1f);
        nav.transform.position = _start;

        return nav.GetComponent<NavTrigger>().Triggered;
    }

我的其他脚本

private bool triggered = false;

    void OnTriggerEnter() {

        this.triggered = true;
    }

    public bool Triggered {

        get { return this.triggered; }
    }

可悲的是，无论运行OnTriggerEnter代码如何，它仍然会返回false.

Sadly, it still returns false regardless of it running the OnTriggerEnter code.

如果有人有任何想法或建议，请告诉我，我将尽一切努力使这项工作成功.

Please, if anyone has any ideas or suggestions at all let me know I will try and do just about anything to make this work.

非常感谢您的帮助！ :)

Thank you very much for your help! :)

推荐答案

OnTriggerEnter 需要一个参数(其他碰撞器)，否则将与Unity期望的签名不匹配.

OnTriggerEnter requires a parameter (Collider other) or it won't match the signature Unity expects.

private bool triggered = false;

    void OnTriggerEnter(Collider other) {
        Debug.Log("Triggered");
        this.triggered = true;
    }

    public bool Triggered {

        get { return this.triggered; }
    }
}

此外，如文档所述:

请注意，只有在对撞机之一也触发时才发送触发事件 附有刚体.

Note that trigger events are only sent if one of the colliders also has a rigid body attached.
